Aquatic Weed Training Course

Attended by Almost 500 Participants

by Tyler J. Koschnick, University of Florida/IFAS Center for Aquatic and Invasive Plants



Every year hundreds of people from the United States and abroad who are involved with
aquatic and invasive plant management converge on south Florida to attend the Aquatic
Weed Control Short Course.

The four-day Short Course is one of the largest Extension programs sponsored by the University
of Florida's Institute of Food and Agricultural Sciences (IFAS).

This year over 460 aquatic and invasive plant managers participated to improve their job
performance and personal safety and to minimize environmental impacts including damage to
non-target species. Florida likely has the largest aquatic plant management program in the world,
spending more than $70 million annually. The state encourages the integration of biological,
chemical, and mechanical methods to remove unwanted aquatic and invasive plants.

Under U.S. federal and state laws, applicators of pesticides classified as restricted use (RU) must
be trained and certified in general knowledge of proper pesticide use and safety (referred to as
core requirements) and in their respective area of work (aquatic; natural areas; turf and
ornamental; etc.) Though no currently registered aquatic herbicides are classified as restricted use
in Florida, most employers and public agencies insist that their applicators be trained and
certified to improve personal safety and application expertise.

The Aquatic Weed Control Short Course is designed primarily to provide the necessary training
to certify people in natural area and aquatic weed control categories. The course also is designed
to offer continuing education units (CEUs) to those already certified and licensed in aquatic plant
management categories. Licenses must be renewed every four years with a required amount of
CEUs in each category.

This year's courses included equipment calibration, aquatic and natural areas weed control, core
examination standards, reading and interpreting a pesticide label, basic weed science, selective
weed management, plant identification, weed ecology, and state and federal rules and regulations.




Presentations also were given on general safety issues for people working in the field. These
included identification of venomous snakes by the Florida Fish and Wildlife Conservation
Commission and information on heat stroke, exhaustion and dehydration by the University of
Florida Health Sciences Department.

Reviewed subjects included pesticide safety, Lygodium management, ditch bank and upland
weed control, biological control of Melaleuca, the herbicide registration process, mosquitoes and
their relationship to aquatic plant control, as well as updates on active ingredients found in
herbicides.

The training course concluded with a field day offering airboat safety training and field
equipment calibration, and an equipment demonstration with a variety of all-terrain vehicles,
herbicide spray rigs, granular blowers, mowers, and tractors. For a photographic tour of the short
course, visit http://conference.ifas.ufl.edu/aw/photos.htm

Exams were offered on the last day, and approximately 160 people were tested on core
requirements or one of the specialized categories.

The University of Florida is one of the only institutions in the country that offers a Short Course
specific to aquatic plant management. The University of Florida's IFAS Center for Aquatic
and Invasive Plants is dedicated to research, Extension, and education as it pertains to invasive
plant management on a local, state, national and international level.

With thousands of certified aquatic pesticide applicators in Florida, we anticipate another
successful course in 2005. Every year, a contingent from other countries arrives to learn about
management practices for aquatic invasive plants in the United States. We welcome and
encourage attendance from those abroad.

Mark your calendars for the
2005 Aquatic Weed Control Short Course:
May 16th-20th, 2005, Fort Lauderdale, Florida.

Land-Grant Universities and Extension

Land-grant universities were established by Congress and signed into law by Abraham Lincoln
in 1862 with the purpose of educating citizens in agriculture, home economics, mechanical arts,
and other practical professions. At that time, more than 50 percent of the U.S. population lived in
rural areas, and 30 percent of the workforce was engaged in farming. Land grant institutions
received funding and/or grants of land.





There are more than 100 land-grant colleges and universities in the U.S. that help meet public
needs by providing practical, applied, non-credit programs called Extension Programs. These
programs are provided through thousands of county and regional extension offices to bring land-
grant expertise to local levels. Extension was formalized by legislation in 1914 and established
the partnership between land-grant institutions and the U.S. Department of Agriculture.
Extension was defined as "developing practical applications of research knowledge, and giving
instruction and practical demonstrations of existing or improved practices or technologies in
agriculture."

During both World Wars and the Great Depression, land-grant institutions and the Extension
Service played dramatic roles in the increase of food production, improvements in marketing and
preservation of fresh foods, development of buying and selling cooperatives, and the teaching of
home economics including nutrition, canning surplus foods, home gardening and poultry
production, skills that helped many farm families survive the years of economic depression.

Today, fewer than 2 percent of Americans farm for a living and only 10 percent live in rural
areas. Yet the USDA Cooperative Extension Service, together with land-grant universities and
colleges, still serves rural, urban, and suburban citizens by teaching agricultural, natural resource,
family and community skills at the local level, including aquatic plant management!

State Gets Earful From Lake Rousseau Anglers


More than 50 fisher men and women recently took the opportunity to tell state water managers
their observations of the plants and fish on Lake Rousseau in west north-central Florida. Some
anglers were not happy; some said things were okay everyone, anglers and water managers
alike, agreed that the muck buildup in the lake is affecting fish spawning; they wish there were a
way to remove the muck and the advancing Lyngbya algae to expose the sandy bottom beneath.


The June 3rd meeting was hosted by Mr. Rob Hatton of the Lake Roussea RV and Fishing
Resort near Dunnellon. Representing the Florida Department of Environmental Protection was
Mr. Terry Sullivan, plant biologist with the Bureau of Invasive Plant Management.
Representing the Florida Fish and Wildlife Conservation Commission was Mr. Jerry
Krummrich, fisheries biologist. State Senator Nancy Argenziano (District 3) also was in
attendance and spoke of her concerns.





Mr. Sullivan presented a slide show on invasive aquatic plant management and fielded questions
about herbicide toxicity, possible herbicide effects from upstream treatments, treatment
frequency and plant abundance. Sullivan said that hydrilla, which only two years ago filled much
of the lake, was now under "maintenance control" thanks to herbicide treatments.

Mr. Krummrich described current electro-fishing data for the lake, saying that Lake Rousseau
ranks "average" in its number of bass over 15 inches long, compared to other bass lakes in the
state. Krummrich said he does not believe Lake Rousseau has been overfished but that for a
number of reasons young fish are not surviving to adulthood.

Senator Argenziano praised plant and fish management efforts in general but specifically
objected to a lack of progress in controlling the nuisance algae, lyngbya. Lyngbya is a black-
looking blue-green algae that is quickly replacing submersed plant beds in a number of north
central Florida rivers and springs. Argenziano believes management agencies are "using band-
aids" to control the rapidly expanding algae.

Audience members asked a variety of questions: "Aren't the fish contaminated by the
herbicides? why the 3-day fish-consumption restriction?"; "What's causing shoreline plant
reduction; isn't there supposed to be a 12-foot fringe all around?"; "Part of the lake bottom has
no plants; didn't the herbicides kill off the eelgrass as well as the hydrilla?"; "Why don't you
control hydrilla by drawing down the lake like they do at Rodman Reservoir?"; "Why have the
floating islands been destroyed?"; "Where have the birds gone?; What about saltwater
encroachment?"; "Why not put it back the way it was?" While some complained that shoreline
plants have been greatly reduced, others complained that their fish camps were difficult to get to
because of too many plants. Another said he lost $100,000 in the six month period that hydrilla
got in the way of fishing, but things are good now.

Lake Toho Muck Removal Project Complete


The largest whole lake enhancement project ever attempted in Florida has been completed on
Lake Tohopekaliga near Kissimmee. Now we wait for rain to refill the lake to judge its success.
"Lake enhancement" here means "enhancement of fish and wildlife habitat," according to the
Florida Fish and Wildife Conservation Commission's Kissimmee office.

Lake Toho, considered a premiere bass fishing lake, had been suffering from static water levels
and excessive plant growth which led to thick deposits of bottom muck. The muck buildup had
filled areas needed for feeding by wading birds and spawning by fish.

The plan has been to dewater (draw down) part of the lake, expose 40% of the lake bottom for
three months, scrape up and remove more than 9 million cubic yards of muck from more than
3,700 bottom acres, and allow the lake to refill with summer rains. The last truckload of muck
was removed and re-filling began on June 15, 2004.

Bulldozers scraped more than 3,700 acres of the exposed bottom of Lake Toho. Here, rows of
muck await removal. Over time, it is expected that the natural plant seed bank will give rise to
healthy stands of knotgrasses, bullrushes, eelgrass and other desirable plants. Workers will
manage for the desirable plant species and against the problematic plant species.

This lake enhancement work has pushed back the process of eutrophication on Lake Toho. One
expected response to the work is the maintenance of a high level of fish productivity for years to
come.

About half of the muck was used to construct in-lake wildlife islands.

In another part of the project, University of Florida researchers, under the direction of Mark
Hoyer, will measure the plant and animal utilization of the man-made islands over time.

Thousands of truckloads of muck were removed. About half the muck was trucked to upland
pastures and other disposal sites.

Management District, the U.S. Army Corps of Engineers, and the Florida Department of
Environmental Regulation, along with researchers of the University of Florida and others. For

Mary's Picks!

New items in the APIRS database that particularly piqued the interest of reader/cataloger,
Mary Langeland;
elaborated by Vic Ramey.



Water lilies and scarabs: faithful partners for 100 million years? by F. Ervik and J.T.
Knudsen. 2003. Biological Journal of the Linnean Society 80:539-543.
The authors believe scarab beetles have been pollinating night-flowering water lilies since
the late Early Cretaceous "the first unambiguous evidence of a plant-pollinator
relationship of this age."



California butterflies: at home with aliens, by P.D. Thacker. 2004. BioScience 54
(3):182-187.
Faced with the loss of its favorite food, stinging nettles, local populations of the red
admiral butterfly came across a plant with a similar chemistry, baby's tears, a non-native
ground cover used in California. The red admiral switched from its native host to the alien
plant. In Davis, California, apparently that is not so strange; other butterflies have
switched to alien plants too.



Species inventory and the local users of the plants and fishes of the Lower Sondu
Miriu wetland of Lake Victoria, Kenya, by J. Gichuki, F. Dahdouh Guebas, J. Mugo, C.
0. Rabuor, L. Triest and F. Dehairs. 2001. Hydrobiologia 458:99-106.
Among other plant uses discussed, the claim is that "a house that uses Cyperus papyrus
for its roof is cooler, and also cheaper to make and maintain than a comparable corrugated
roofed house."



Viscoelasticity of the giant reed material Arundo donax, by A.E. Lord. 2003. Wood
Science and Technology 37(3-4): 177-188.




Using highly advanced measurements and modelling, the authors show why giant reed "is
almost exclusively the material of choice to manufacture woodwind musical instruemtn
reeds."




Evidence for seed dispersal by the catfish Auchenipterichthys longimanus in an
Amazonian lake, by S. Mannheimer, G. Bevilacqua, E.P. Caramaschi and F.R. Scarano.
2003. Journal of Tropical Ecology 19:215-218.
The stomachs of 40% of the Amazonian catfish studied contained fruits, infructescenses
or whole seeds of various plants, including Alchornea schomburgkiana, Licania,
Psychotria, Bredemeiera, Malonetia, Ludwigia, Oryza and Paspalum. "This result
indicates dispersal potential and similar findings have been reported previously for other
catfishes."




Zero water flows in the carnivorous genus Genlisea, by L. Adamec. 2003. Carnivorous
Plant Newsletter 32:46-48.
Utricularia carnivorous plants have bladders that suck in their prey, but how is prey
captured in plants of the carnivorous plant genus Genlisea? This is especially mysterious
considering that in Genlisea traps there is no water flow, no pumping to create a vacuum.




Hemlock water dropwort (Oenanthe crocata), dead man's fingers. 2001. IACR-Center
for Aquatic Plant Management, England, CAPM Information Sheet 34.
This aquatic plant is "the most toxic plant in Britain to both humans and animals" the
leaves are celery-like and smell like celery or parsley horses, cows and humans mistake
it for lunch.




On the uses of Zostera marina, mainly in Norway, by T. Alm. 2003. Economic Botany
57(4):640-645.
This ethnobotanical review found that in Norway in the 1700s to the 1800s this abundant
marine grass was used variously as manure; stuffing for mattresses; for filling between the
logs of wooden houses; as fodder for cows; to prepare fish; and as ground cover for sheep.

Species targeted habitat restoration: a mitigation option within identified historical
habitat and critical habitat area, by C. Carpenter. 2003. In: Proceedings of the 30th
Annual Conference on Ecosystems Restoration and Creation, Hillsborough Community
College, Tampa. Pp: 63-69.
Within the city limits of West Palm Beach, Florida, rather than build houses on 600 acres
in endangered Everglades snail kite habitat, and to settle a suit brought by the National
Audubon Society and The Sierra Club, 300 acres were given to human house-building and
300 acres were given to the snail kite. After extensive work to remove invasive plants and
to re-establish cypress heads and marshes, and otherwise to restore the area to pre-1942
conditions, the snail kite has returned to the area.

"The Islands the Alligators Build"

by Frank M. Chapman, reprinted from Our Animal Friends 21(9) (May, 1894), contributed by
Chet Van Duzer

Editor's Note: This article from 1894 takes place in your editors' own backyard. Thank you to
Chet Van Duzer for the contribution. See the announcement of Mr. Van Duzer's forthcoming
book, Floating Islands: A Global Bibliography
with an Edition and Translation of G. C. Munz's Exercitatio academic de insulis natantibus
(1711) below.

Few animals are more friendless than the alligator. With claims to neither beauty nor
intelligence, he is not handsome enough to win our admiration, nor dangerous enough to make us
respect him. For hours he basks in the sun, floating on the surface of the water, or lying on some
muddy bank, apparently as useless as the log of wood he so much resembles. Every man's hand is
raised against him. He is killed by the tourist in pure wantonness, simply because he affords a
mark for the ever-ready rifle. Hunters slay alligators by thousands for their hides and teeth.
Indeed, it is for these alone that the alligator is prized. I think, however, that, like everything else
in nature, the alligator plays a part in the drama of animal life for which he is especially adapted.

It is said that on the lower Mississippi River alligators feed on muskrats, and the recent decrease
in the number of alligators has been followed by a corresponding increase in the number of
muskrats, which seriously weaken the levees by burrowing in them. If this be true, the alligator is
here of direct value to the planter, and should therefore be protected by law.

However, my plea for the alligator is not based on his powers as a destroyer of muskrats, but on
his services as a land-maker. It does not seem probable that so stupid and sluggish an animal
should be a factor in changing a stagnant pool of water a breeding ground for miasmatic germs -
into a fertile pasture where cattle may graze. Nevertheless, I think it can be proven that he aids in
accomplishing this remarkable transformation.

Several years ago I passed the winter studying birds and mammals near Gainesville, Florida.
Among my especial desiderata were a singular little round-tailed muskrat, known as Neofiber
(which had previously been found only on the Indian River), and a peculiar semi-aquatic hare. A
resident of the region suggested that these animals might be found on the floating islands of
"Bevan's Arm." This "Arm," a branch of Alachua Lake, is what is known in Florida as a "bonnet
lake." The name will be familiar to any one who has visited Florida, for "bonnet lakes" are
abundant throughout the State. Imagine a lake so thickly covered with a growth of pond-lilies that




the water shows only in occasional patches. The lilies are both of the yellow and of the white
varieties, but the former are by far the larger and more numerous. Some leaves measure eighteen
inches in diameter, and the stems of many project nearly two feet above the surface of the lake.
The water is sometimes fifteen or twenty feet in depth, and in the clearer spaces much deeper. It
is filled with many species of aquatic plants, in which one's oars become entangled, and these,
added to the abundance of lily leaves or "bonnets," make rowing a difficult and tiresome matter.

In one of the open spaces near the centre of the "Arm," which was here about half a mile in
width, were the islands. There were several of them, irregularly circular in shape and varying in
diameter from about ten to nearly fifty feet. They were densely grown with reeds and grasses of
many species, and, in some places, tall flag-like sedges and button baskets grew.

To a naturalist, floating islands possess a strong fascination. They are like earthly satellites
floating about in watery orbits. The animals which inhabit them seem to belong to a sphere of
their own. The isolation of their island-home affords them protection from their mainland
enemies, and this is doubtless why animals are so abundant on the islands in the "Arm." Certain it
is, I have never seen a bit of ground of similar extent so densely populated.

Rowing slowly out through the "bonnets," one was greeted by a chorus of frog-like gruntings
which seemed to issue from under every lily leaf. It was made by young alligators. The "Arm"
was a nursery for them. They were of all sizes, from little fellows six or eight inches in length,
born the preceding summer, to fully grown adults measuring ten feet or more. The smaller ones
are found in schools, families, perhaps; occasionally, to sun themselves, they crawl upon lily
leaves floating on the surface of the water, making as ideal pictures of lazy contentment as one
can well imagine. The larger leaves will support the weight of an alligator three feet in length.

One of the larger islands was my daily resort for nearly two weeks, and I will confine my account
to the history of this particular island, speaking first of the life upon it, then of its probable origin.

I always approached it with caution, in order that I might have a glimpse of its largest inhabitant.
This was an alligator about eight feet in length. His habit of crawling from the water on to the
island at a certain place had resulted in his wearing away the shore, until he had formed a
miniature harbor. He "builded better than he knew," and here on the muddy shore he dozed the
hours away, enjoying, although he did not know it, the fruits of his own or his fellows' labors. On
my appearance he would half slide, half roll, off into the water; the waves rippled outward in
ever- widening circles; a few bubbles rose to the surface, and I saw no more of the king of the
islands that day.

My landing was a few feet beyond. It was made, and my boat "beached" in a unique manner. The
island was two to three feet in thickness, and floated in water from fifteen to twenty feet in depth.
As I stepped from my canoe on to its edge it sank slowly beneath my weight, and, stepping
backwards, I could thus draw the floating canoe after me; but as I advanced toward the centre of




the island the shore rose, and the canoe was lifted from the water by this kind of natural drydock.

Progress now was very much like walking on cracked or partially melted ice. Where the grass
grew thickly there was a firm footing, but the spaces between the little hillocks were
treacherously soft. To fall through an island would no doubt be a novel experience, but one that
the experimenter would doubtless never attempt again.

Although none of the residents were visible, it required but a glance to show that this island was
thickly populated. Broad avenues entered and left the water. There was a network of roads,
pathways and trails leading to grassy nests well hidden at the base of a hillock, or to underground
tunnels with entrances half-closed with mud. Close inspection showed the tracks of many feet. As
I walked carefully about this city for it was nothing less I felt like a Brobdingnag in Lilliputia.
While the place was apparently deserted, I knew that the inhabitants were all at home. With them
it was night, and my presence was doubtless causing many a heart near me to beat with
unaccustomed rapidity.

On this little fragment of earth there proved to be representatives of almost every class of the
animal kingdom. The broad avenues leading to the water were made by the marsh hare. This hare
resembles our common "cotton-tail," but its tail is of drab, and not of white, cotton, while its feet
are less heavily furred and are partly webbed. Its presence on these islands shows how aquatic are
its habits. It swims readily, and is thus especially fitted to live in the low-lands of the South,
where floods are more or less frequent. Indeed, the habitat of this hare and its congener, the water
hare, is entirely included within that part of the lower Mississippi Valley and adjacent regions
which is subject to inundations.

The smaller paths led to nests of dry grasses in the hillocks. These were the homes of marsh-rats,
a native species, smaller than our imported house-rats, and with a denser, heavier fur, which
sheds water easily, and thus forms an excellent suit for these swamp-loving animals. The
underground passages proved to have been made by the rare neofiber, and there were also some
of its singular dome-shaped houses, built of woven grasses, with a single chamber, having both
exit and entrance.

Here, then, were three species of mammals living in harmony on a bit of ground only a few yards
square.

Many species of birds occasionally used the island as a nesting place. There were white herons
and blue, bitterns, ducks and others; but I will tell only of those which seemed to make the island
their home. Of these probably the most common were the boat-tail grackles, a name they have
acquired from their habit when on the wing of holding their long tail-feathers on edge, as it were,
the tail thus resembling in form the hull of a boat. The males are beautiful birds, with glossy blue-
black plumage, while the females are of an inconspicuous dull brown. They place their large
nests of grasses in the tall flags, laying eggs curiously ornamented with hieroglyphic-like




markings.


There were also great numbers of red-winged blackbirds, the males having scarlet epaulets and
the females, as usual, being dull, obscure-looking birds, but I do not think they nested on this
particular island.

Green herons built their platform-like nests of sticks in the button-bushes near by. Their young
were ungainly accumulations of wings, legs, and a long neck, all radiating from one small centre,
and a scanty covering of white hair-like feathers did not add to their gracefulness. A strange,
startling voice I heard sometimes in the reeds probably belonged to a king rail, who showed
himself on only one or two occasions. It was a most singular cry, a loud Bap, Bap, Bap, many
times repeated, as though some one was rapidly striking a resounding board.

Florida gallinules were always common, and in May a number of their purple cousins arrived
from the South. It was a pleasure to watch these graceful birds stepping daintily over the lily
leaves while feeding. Their many strange notes all bore a suggestion of the barnyard about them,
a character quite out of keeping with their surroundings. I found only one nest, constructed of
reeds and placed like a staging over the water. The plumage of the purple gallinule is of a deep
indigo below and of a bright greenish-blue above, and it wears a scarlet helmet. Its under tail-
feathers are white, and when the bird is on the wing, holding its tail at right angles to the plane of
its body, this white mark becomes a conspicuous object.

One morning I found a "pellet" which had been disgorged on the island by some owl. It contained
the skull of a cotton-rat, which had probably fallen victim to a barred owl.

Of reptiles, in addition to the alligators, there were snakes and turtles. One morning I saw a
hideous moccasin snake lying coiled in the grasses almost at my feet a loathsome creature,
nearly four feet in length, possessed of a power which rendered his very hideousness strangely
attractive. Poisonous snakes have the sort of fascination for us that belongs to scaffolds and
guillotines and other means of sudden and violent death. I killed this snake and took him home as
a specimen, assuring myself, however, that he was thoroughly dead before placing him in the
canoe, where he would not have proved an especially desirable companion had he revived when I
was halfway to the shore.

A few days later a small water turtle which had come ashore to lay its eggs was found. It had laid
one egg in a small hole at the base of a hillock, and another was laid in the canoe.

Doubtless there are several kinds of insects on the island, but I found only one species. This was
an ant. Probably the ants on this little detached world were more numerous than all the other
animals combined. They lived in the only dry spot, a little mound near the centre of the island.
Their home was inconspicuous, and might have escaped notice entirely had I not sat down on it!




To return now to the history of these islands and the part alligators play in building them. These
gigantic lizards love to lie in the soft mud at the bottom of lakes; and they carefully select such
places in which to hibernate during the colder months.

Now, if one could see a "bonnet" lake from which the water had disappeared, it would be noticed
that its bottom is a network of interlacing lily-pads. The roots are as large as a man's arm, and it
will be readily seen how they would prevent a large alligator from snugly nestling in the oozy
mud. The alligator, therefore, prepares his bed by biting and pulling out these roots, and they
come floating to the surface, showing plainly the marks of his teeth, to form the framework of a
future island. Every stage of its growth could be seen in the "Arm." Numbers of these roots float
together and form a kind of raft. A scum collects about it, dust settles upon it, and the whole soon
looks like a sheet of mud which undulates with the waves. As it becomes firmer, a small plant,
always of the same species, makes its appearance, entirely covering the island, and growing so
evenly that one might suppose its seed had been carefully sowed by hand. Later stages are now
merely questions of time, but it is probably only a few years before the roots torn from the bed of
the lake by the alligator are firmly woven into a compact mass by the grasses and reeds which
take possession of it, and we have then an island quite similar to the one I have described.

This, it is true, is not a pasture, but it may become one at any time. Some day a strong wind will
blow this island ashore-indeed, I saw islands which had been stranded-and then the roots in its
bottom will prove living anchors, holding it to its moorings, and by and by the floating island will
become firm ground over which cattle cattle may graze. As island after island is blown against
this one, the "Arm" recedes, the shore becomes dryer, and ere long it will be firm enough to
support cattle which are attracted by its luxuriant growth of grasses.

And now what becomes of our villagers? Search the shore as you will, comparatively few traces
of them are to be found. Robbed of the isolation of an insular life, they soon disappear to seek
new homes where they will be more secure from the attacks of their enemies. The alligator gives
place to the cow, the grassy nests of the marsh-rats and neofiber are soon overturned by prying
pigs.

Floating Islands: A Global Bibliography

with an Edition and Translation of G. C. Munz's
Exercitatio academic de insulis natantibus (1711)


by Chet Van Duzer




This book is a unique treasury of information about one of nature's marvels: floating
islands. The bibliography contains more than 1500 citations of books and articles in twenty
languages on the subject; the entries are annotated and cross-referenced, and there are both
thematic and geographic indices. All aspects of floating islands are addressed, including the
formation of floating islands, the causes of their buoyancy, their role in the ecology of lakes and
wetlands, their flora and fauna, their role in the dispersal of plants and animals, and methods for
controlling and managing them. Works are also cited on artificial floating islands used for
agriculture, human habitation, wildlife habitat, and improvement of water quality; and floating
islands in literature, myth, and legend. The book includes the text and an English translation, with
detailed notes, of G. C. Munz's rare 1711 thesis on floating islands, Exercitatio academic de
inulii natantibus, as well as photographs of several floating islands.

Hardcover, 27 cm, 415 pp. with indices and illustrations.
ISBN 0-9755424-0-0
Library of Congress Control Number: 2004093899
Forthcoming from Cantor Press (Summer 2004)

"Chet Van Duzer has done the long, hard, exhaustive, in-depth, multidiscipline, and multilingual
'homework' for all the world's researchers of floating islands, and for others interested in a
fascinating natural feature." Peter A. Stone, Hydrologist, South Carolina Department of Health

Grant, the national Aquatic Plant Management Society, the Florida Aquatic Plant Management Society, and
from the U.S. Army Corps of Engineers Jacksonville Office.


NATIVE AQUATIC PLANTS


























Lest we forget, with so much current emphasis on invasive non-natives, most plants in the U.S. are
native; beneficial to animals, humans, and the environment; and often beautiful. So, here are two photo-
murals of 76 native freshwater plants of the U.S.. Of the plants depicted, 100% are in Florida; 97% are also
found in the rest of the Southeast U.S.; 50% are found in the Eastern U.S.; 22% are found in the West; and 22%
are found throughout most of the U.S.

Aquathol Manufacturer Comes Through Again!

Mr. Bill Moore of Cerexagri, manufacturer of the aquatic herbicide Aquathol, presents a check
to Mr. Vic Ramey of the UF-IFAS Center for Aquatic and Invasive Plants. The $15,000
unrestricted contribution will be used by the Information Office in the production of educational
materials for aquatic plant management personnel as well as for students and the general public.

This is the sixth such contribution from Cerexagri to the Center's Information Office in recent
years. Mr. Gerald Adrian is the company's Aquatic Sales Manager, and Mr. Moore is the
company's Florida representative.

Previous contributions included seed money for the Office's line-drawings project and plant
photography collection, the aquatic plant identification deck and the laminated photo-murals for
schoolteachers. Such unrestricted support from private sources enables the Office to do much
more than it could with base funding alone.

We greatly appreciate it!

44th Annual

Aquatic Plant Management Society Meeting A

Report

Tampa, Florida was the host city for the 44th Annual Aquatic Plant Management Society
(APMS) meeting held July 11 th 14th. 220 delegates attended, including 18 students, to learn the
latest in aquatic plant management from 49 papers and 23 posters. Nine of the presentations were
given by students in the annual student paper competition. Seven of the students are working on
their Ph.D. and two on their Master's degree.

Sarah Habrun of the College of Charleston won the student competition for her presentation,
Investigation of a Novel Cyanobacteria Linked to Avian Vacuolar Myelinopathy (AVM). AVM
is a fatal bird disease and Ms. Habrun states that "the most probable hypothesis is that birds
ingest a neurotoxin produced by epiphytic cyanobacteria." The toxic cyanobacteria has been
closely associated with Hydrilla verticillata in reservoirs in the southeastern U.S., and has
already adversely affected local breeding populations of American bald eagles.

All student presenters received a copy of C.D. Sculthorpe's The Biology ofAquatic Vascular
Plants, or the text of their choice.

Linda Nelson and Judy Shearer from the U.S. Army Engineer Research and Development
Center, Environmental Laboratory won the poster competition with their poster, "Integrating
Triclopyr and a Fungal Pathogen (Mycoleptodiscus terrestris) for Control of Eurasian
Watermilfoil (Myriophyllum spicatum). The pair received a perfect score from a judging panel
of student attendees.

A variety of interesting presentations were given, including economic studies, updates on
biological and chemical control methods, ecological studies, and a special session on plant
resistance and tolerance to aquatic herbicides.

Dr. T. Wayne Miller, Jr., founder of the APMS (originally known as the Hyacinth Control
Society), presented his recollections from approximately 40 years of aquatic plant management
experience beginning in 1960. He displayed a photograph of water hyacinths blocking access to a
boat dock in Lee County, Florida from a 1960 edition of The Saturday Evening Post that inspired
county commissioners to create the first hyacinth control program in the nation.

A review from regional APMS chapters was given, including Florida, Midsouth, Midwest,




Northeast, Texas, and South Carolina. Chapter membership numbers range from less than 100 to
approximately 500 in the Florida chapter. The APMS and most regional chapters award student
scholarships in aquatic plant sciences yearly.

The 45th Annual APMS meeting will be held in San Antonio, Texas. See http://www.apms.org
for more information on all APMS activities and events.

23(2) AQUAPHYTE AQUAPHYTE ONLINE SUMMER 2004 Aquatic Weed Training Course Attended by Almost 500 Participantsby Tyler J. Koschnick, University of Florida/IFAS Center for Aquatic and Invasive Plants Every year hundreds of people from the United States and abroad who are involved with aquatic and invasive plant management converge on south Florida to attend the Aquatic Weed Control Short Course. The four-day Short Course is one of the largest Extension programs sponsored by the University of Floridas Institute of Food and Agricultural Sciences (IFAS). This year over 460 aquatic and invasive plant managers participated to improve their job performance and personal safety and to minimize environmental impacts including damage to non-target species. Florida likely has the largest aquatic plant management program in the world, spending more than $70 million annually. The state encourages the integration of biological, chemical, and mechanical methods to remove unwanted aquatic and invasive plants. Under U.S. federal and state laws, applicators of pesticides classified as restricted use (RU) must be trained and certified in general knowledge of proper pesticide use and safety (referred to as core requirements) and in their respective area of work (aquatic; natural areas; turf and ornamental; etc.) Though no currently registered aquatic herbicides are classified as restricted use in Florida, most employers and public agencies insist that their applicators be trained and certified to improve personal safety and application expertise. The Aquatic Weed Control Short Course is designed primarily to provide the necessary training to certify people in natural area and aquatic weed control categories. The course also is designed to offer continuing education units (CEUs) to those already certified and licensed in aquatic plant management categories. Licenses must be renewed every four years with a required amount of CEUs in each category. This years courses included equipment calibration, aquatic and natural areas weed control, core examination standards, reading and interpreting a pesticide label, basic weed science, selective weed management, plant identification, weed ecology, and state and federal rules and regulations. http://plants.ifas.ufl.edu/aqs04-sc.html (1 of 3) [6/6/2008 1:50:41 PM]

23(2) AQUAPHYTE Presentations also were given on general safety issues for people working in the field. These included identification of venomous snakes by the Florida Fish and Wildlife Conservation Commission and information on heat stroke, exhaustion and dehydration by the University of Florida Health Sciences Department. Reviewed subjects included pesticide safety, Lygodium management, ditch bank and upland weed control, biological control of Melaleuca, the herbicide registration process, mosquitoes and their relationship to aquatic plant control, as well as updates on active ingredients found in herbicides. The training course concluded with a field day offering airboat safety training and field equipment calibration, and an equipment demonstration with a variety of all-terrain vehicles, herbicide spray rigs, granular blowers, mowers, and tractors. For a photographic tour of the short course, visit http://conference.ifas.ufl.edu/aw/photos.htm Exams were offered on the last day, and approximately 160 people were tested on core requirements or one of the specialized categories. The University of Florida is one of the only institutions in the country that offers a Short Course specific to aquatic plant management. The University of Floridas IFAS Center for Aquatic and Invasive Plants is dedicated to research, Extension, and education as it pertains to invasive plant management on a local, state, national and international level. With thousands of certified aquatic pesticide applicators in Florida, we anticipate another successful course in 2005. Every year, a contingent from other countries arrives to learn about management practices for aquatic invasive plants in the United States. We welcome and encourage attendance from those abroad. Mark your calendars for the 2005 Aquatic Weed Control Short Course: May 16th-20th, 2005, Fort Lauderdale, Florida. See: http://conference.ifas.ufl.edu/aw/ Land-Grant Universities and ExtensionLand-grant universities were established by Congress and signed into law by Abraham Lincoln in 1862 with the purpose of educating citizens in agriculture, home economics, mechanical arts, and other practical professions. At that time, more than 50 percent of the U.S. population lived in rural areas, and 30 percent of the workforce was engaged in farming. Land grant institutions received funding and/or grants of land. http://plants.ifas.ufl.edu/aqs04-sc.html (2 of 3) [6/6/2008 1:50:41 PM]

23(2) AQUAPHYTE There are more than 100 land-grant colleges and universities in the U.S. that help meet public needs by providing practical, applied, non-credit programs called Extension Programs. These programs are provided through thousands of county and regional extension offices to bring landgrant expertise to local levels. Extension was formalized by legislation in 1914 and established the partnership between land-grant institutions and the U.S. Department of Agriculture. Extension was defined as developing practical applications of research knowledge, and giving instruction and practical demonstrations of existing or improved practices or technologies in agriculture. During both World Wars and the Great Depression, land-grant institutions and the Extension Service played dramatic roles in the increase of food production, improvements in marketing and preservation of fresh foods, development of buying and selling cooperatives, and the teaching of home economics including nutrition, canning surplus foods, home gardening and poultry production, skills that helped many farm families survive the years of economic depression. Today, fewer than 2 percent of Americans farm for a living and only 10 percent live in rural areas. Yet the USDA Cooperative Extension Service, together with land-grant universities and colleges, still serves rural, urban, and suburban citizens by teaching agricultural, natural resource, family and community skills at the local level, including aquatic plant management!

23(2) AQUAPHYTE AQUAPHYTE ONLINE SUMMER 2004 State Gets Earful From Lake Rousseau Anglers More than 50 fisher men and women recently took the opportunity to tell state water managers their observations of the plants and fish on Lake Rousseau in west north-central Florida. Some anglers were not happy; some said things were okay everyone, anglers and water managers alike, agreed that the muck buildup in the lake is affecting fish spawning; they wish there were a way to remove the muck and the advancing Lyngbya algae to expose the sandy bottom beneath. The June 3rd meeting was hosted by Mr. Rob Hatton of the Lake Roussea RV and Fishing Resort near Dunnellon. Representing the Florida Department of Environmental Protection was Mr. Terry Sullivan, plant biologist with the Bureau of Invasive Plant Management. Representing the Florida Fish and Wildlife Conservation Commission was Mr. Jerry Krummrich, fisheries biologist. State Senator Nancy Argenziano (District 3) also was in attendance and spoke of her concerns. http://plants.ifas.ufl.edu/aqs04-ro.html (1 of 2) [6/6/2008 1:50:44 PM]

23(2) AQUAPHYTE Mr. Sullivan presented a slide show on invasive aquatic plant management and fielded questions about herbicide toxicity, possible herbicide effects from upstream treatments, treatment frequency and plant abundance. Sullivan said that hydrilla, which only two years ago filled much of the lake, was now under maintenance control thanks to herbicide treatments. Mr. Krummrich described current electro-fishing data for the lake, saying that Lake Rousseau ranks average in its number of bass over 15 inches long, compared to other bass lakes in the state. Krummrich said he does not believe Lake Rousseau has been overfished but that for a number of reasons young fish are not surviving to adulthood. Senator Argenziano praised plant and fish management efforts in general but specifically objected to a lack of progress in controlling the nuisance algae, lyngbya. Lyngbya is a blacklooking blue-green algae that is quickly replacing submersed plant beds in a number of north central Florida rivers and springs. Argenziano believes management agencies are using bandaids to control the rapidly expanding algae. Audience members asked a variety of questions: Arent the fish contaminated by the herbicides? why the 3-day fish-consumption restriction?; Whats causing shoreline plant reduction; isnt there supposed to be a 12-foot fringe all around?; Part of the lake bottom has no plants; didnt the herbicides kill off the eelgrass as well as the hydrilla?; Why dont you control hydrilla by drawing down the lake like they do at Rodman Reservoir?; Why have the floating islands been destroyed?; Where have the birds gone?; What about saltwater encroachment?; Why not put it back the way it was? While some complained that shoreline plants have been greatly reduced, others complained that their fish camps were difficult to get to because of too many plants. Another said he lost $100,000 in the six month period that hydrilla got in the way of fishing, but things are good now. V.R.

23(2) AQUAPHYTE AQUAPHYTE ONLINE SUMMER 2004 Lake Toho Muck Removal Project Complete The largest whole lake enhancement project ever attempted in Florida has been completed on Lake Tohopekaliga near Kissimmee. Now we wait for rain to refill the lake to judge its success. Lake enhancement here means enhancement of fish and wildlife habitat, according to the Florida Fish and Wildife Conservation Commissions Kissimmee office. Lake Toho, considered a premiere bass fishing lake, had been suffering from static water levels and excessive plant growth which led to thick deposits of bottom muck. The muck buildup had filled areas needed for feeding by wading birds and spawning by fish. The plan has been to dewater (draw down) part of the lake, expose 40% of the lake bottom for three months, scrape up and remove more than 9 million cubic yards of muck from more than 3,700 bottom acres, and allow the lake to refill with summer rains. The last truckload of muck was removed and re-filling began on June 15, 2004. bulldozers scraped 3,700 acres thousands of truckloads of muck half the muck was used for islands man-made islands will be monitored See color pictures of the Lake Toho project here. http://plants.ifas.ufl.edu/aqs04-to.html (1 of 2) [6/6/2008 1:50:45 PM]

23(2) AQUAPHYTE Bulldozers scraped more than 3,700 acres of the exposed bottom of Lake Toho. Here, rows of muck await removal. Over time, it is expected that the natural plant seed bank will give rise to healthy stands of knotgrasses, bullrushes, eelgrass and other desirable plants. Workers will manage for the desirable plant species and against the problematic plant species. This lake enhancement work has pushed back the process of eutrophication on Lake Toho. One expected response to the work is the maintenance of a high level of fish productivity for years to come. V.R. Photo captions: Bulldozers scraped more than 3,700 acres of the exposed bottom of Lake Toho. Here, rows of muck await removal. About half of the muck was used to construct in-lake wildlife islands. In another part of the project, University of Florida researchers, under the direction of Mark Hoyer, will measure the plant and animal utilization of the man-made islands over time. Thousands of truckloads of muck were removed. About half the muck was trucked to upland pastures and other disposal sites. Photos by Chris Michael, FWC.

24(1) AQUAPHYTE AQUAPHYTE ONLINE SUMMER 2004 "The Islands the Alligators Build" by Frank M. Chapman, reprinted from Our Animal Friends 21(9) (May, 1894), contributed by Chet Van Duzer Editors Note: This article from 1894 takes place in your editors own backyard. Thank you to Chet Van Duzer for the contribution. See the announcement of Mr. Van Duzers forthcoming book, Floating Islands: A Global Bibliography with an Edition and Translation of G.C. Munzs Exercitatio academica de insulis natantibus (1711) below. Few animals are more friendless than the alligator. With claims to neither beauty nor intelligence, he is not handsome enough to win our admiration, nor dangerous enough to make us respect him. For hours he basks in the sun, floating on the surface of the water, or lying on some muddy bank, apparently as useless as the log of wood he so much resembles. Every man's hand is raised against him. He is killed by the tourist in pure wantonness, simply because he affords a mark for the ever-ready rifle. Hunters slay alligators by thousands for their hides and teeth. Indeed, it is for these alone that the alligator is prized. I think, however, that, like everything else in nature, the alligator plays a part in the drama of animal life for which he is especially adapted. It is said that on the lower Mississippi River alligators feed on muskrats, and the recent decrease in the number of alligators has been followed by a corresponding increase in the number of muskrats, which seriously weaken the levees by burrowing in them. If this be true, the alligator is here of direct value to the planter, and should therefore be protected by law. However, my plea for the alligator is not based on his powers as a destroyer of muskrats, but on his services as a land-maker. It does not seem probable that so stupid and sluggish an animal should be a factor in changing a stagnant pool of water a breeding ground for miasmatic germs into a fertile pasture where cattle may graze. Nevertheless, I think it can be proven that he aids in accomplishing this remarkable transformation. Several years ago I passed the winter studying birds and mammals near Gainesville, Florida. Among my especial desiderata were a singular little round-tailed muskrat, known as Neofiber (which had previously been found only on the Indian River), and a peculiar semi-aquatic hare. A resident of the region suggested that these animals might be found on the floating islands of "Bevan's Arm." This "Arm," a branch of Alachua Lake, is what is known in Florida as a "bonnet lake." The name will be familiar to any one who has visited Florida, for "bonnet lakes" are abundant throughout the State. Imagine a lake so thickly covered with a growth of pond-lilies that http://plants.ifas.ufl.edu/aqs04-al.html (1 of 6) [6/6/2008 1:50:46 PM]

24(1) AQUAPHYTE the water shows only in occasional patches. The lilies are both of the yellow and of the white varieties, but the former are by far the larger and more numerous. Some leaves measure eighteen inches in diameter, and the stems of many project nearly two feet above the surface of the lake. The water is sometimes fifteen or twenty feet in depth, and in the clearer spaces much deeper. It is filled with many species of aquatic plants, in which one's oars become entangled, and these, added to the abundance of lily leaves or "bonnets," make rowing a difficult and tiresome matter. In one of the open spaces near the centre of the "Arm," which was here about half a mile in width, were the islands. There were several of them, irregularly circular in shape and varying in diameter from about ten to nearly fifty feet. They were densely grown with reeds and grasses of many species, and, in some places, tall flag-like sedges and button baskets grew. To a naturalist, floating islands possess a strong fascination. They are like earthly satellites floating about in watery orbits. The animals which inhabit them seem to belong to a sphere of their own. The isolation of their island-home affords them protection from their mainland enemies, and this is doubtless why animals are so abundant on the islands in the "Arm." Certain it is, I have never seen a bit of ground of similar extent so densely populated. Rowing slowly out through the "bonnets," one was greeted by a chorus of frog-like gruntings which seemed to issue from under every lily leaf. It was made by young alligators. The "Arm" was a nursery for them. They were of all sizes, from little fellows six or eight inches in length, born the preceding summer, to fully grown adults measuring ten feet or more. The smaller ones are found in schools, families, perhaps; occasionally, to sun themselves, they crawl upon lily leaves floating on the surface of the water, making as ideal pictures of lazy contentment as one can well imagine. The larger leaves will support the weight of an alligator three feet in length. One of the larger islands was my daily resort for nearly two weeks, and I will confine my account to the history of this particular island, speaking first of the life upon it, then of its probable origin. I always approached it with caution, in order that I might have a glimpse of its largest inhabitant. This was an alligator about eight feet in length. His habit of crawling from the water on to the island at a certain place had resulted in his wearing away the shore, until he had formed a miniature harbor. He "builded better than he knew," and here on the muddy shore he dozed the hours away, enjoying, although he did not know it, the fruits of his own or his fellows' labors. On my appearance he would half slide, half roll, off into the water; the waves rippled outward in everwidening circles; a few bubbles rose to the surface, and I saw no more of the king of the islands that day. My landing was a few feet beyond. It was made, and my boat "beached" in a unique manner. The island was two to three feet in thickness, and floated in water from fifteen to twenty feet in depth. As I stepped from my canoe on to its edge it sank slowly beneath my weight, and, stepping backwards, I could thus draw the floating canoe after me; but as I advanced toward the centre of http://plants.ifas.ufl.edu/aqs04-al.html (2 of 6) [6/6/2008 1:50:46 PM]

24(1) AQUAPHYTE the island the shore rose, and the canoe was lifted from the water by this kind of natural drydock. Progress now was very much like walking on cracked or partially melted ice. Where the grass grew thickly there was a firm footing, but the spaces between the little hillocks were treacherously soft. To fall through an island would no doubt be a novel experience, but one that the experimenter would doubtless never attempt again. Although none of the residents were visible, it required but a glance to show that this island was thickly populated. Broad avenues entered and left the water. There was a network of roads, pathways and trails leading to grassy nests well hidden at the base of a hillock, or to underground tunnels with entrances half-closed with mud. Close inspection showed the tracks of many feet. As I walked carefully about this city for it was nothing less I felt like a Brobdingnag in Lilliputia. While the place was apparently deserted, I knew that the inhabitants were all at home. With them it was night, and my presence was doubtless causing many a heart near me to beat with unaccustomed rapidity. On this little fragment of earth there proved to be representatives of almost every class of the animal kingdom. The broad avenues leading to the water were made by the marsh hare. This hare resembles our common "cotton-tail," but its tail is of drab, and not of white, cotton, while its feet are less heavily furred and are partly webbed. Its presence on these islands shows how aquatic are its habits. It swims readily, and is thus especially fitted to live in the low-lands of the South, where floods are more or less frequent. Indeed, the habitat of this hare and its congener, the water hare, is entirely included within that part of the lower Mississippi Valley and adjacent regions which is subject to inundations. The smaller paths led to nests of dry grasses in the hillocks. These were the homes of marsh-rats, a native species, smaller than our imported house-rats, and with a denser, heavier fur, which sheds water easily, and thus forms an excellent suit for these swamp-loving animals. The underground passages proved to have been made by the rare neofiber, and there were also some of its singular dome-shaped houses, built of woven grasses, with a single chamber, having both exit and entrance. Here, then, were three species of mammals living in harmony on a bit of ground only a few yards square. Many species of birds occasionally used the island as a nesting place. There were white herons and blue, bitterns, ducks and others; but I will tell only of those which seemed to make the island their home. Of these probably the most common were the boat-tail grackles, a name they have acquired from their habit when on the wing of holding their long tail-feathers on edge, as it were, the tail thus resembling in form the hull of a boat. The males are beautiful birds, with glossy blueblack plumage, while the females are of an inconspicuous dull brown. They place their large nests of grasses in the tall flags, laying eggs curiously ornamented with hieroglyphic-like http://plants.ifas.ufl.edu/aqs04-al.html (3 of 6) [6/6/2008 1:50:46 PM]

24(1) AQUAPHYTE markings. There were also great numbers of red-winged blackbirds, the males having scarlet epaulets , and the females, as usual, being dull, obscure-looking birds, but I do not think they nested on this particular island. Green herons built their platform-like nests of sticks in the button-bushes near by. Their young were ungainly accumulations of wings, legs, and a long neck, all radiating from one small centre, and a scanty covering of white hair-like feathers did not add to their gracefulness. A strange, startling voice I heard sometimes in the reeds probably belonged to a king rail, who showed himself on only one or two occasions. It was a most singular cry, a loud Bap, Bap, Bap, many times repeated, as though some one was rapidly striking a resounding board. Florida gallinules were always common, and in May a number of their purple cousins arrived from the South. It was a pleasure to watch these graceful birds stepping daintily over the lily leaves while feeding. Their many strange notes all bore a suggestion of the barnyard about them, a character quite out of keeping with their surroundings. I found only one nest, constructed of reeds and placed like a staging over the water. The plumage of the purple gallinule is of a deep indigo below and of a bright greenish-blue above, and it wears a scarlet helmet. Its under tailfeathers are white, and when the bird is on the wing, holding its tail at right angles to the plane of its body, this white mark becomes a conspicuous object. One morning I found a "pellet" which had been disgorged on the island by some owl. It contained the skull of a cotton-rat, which had probably fallen victim to a barred owl. Of reptiles, in addition to the alligators, there were snakes and turtles. One morning I saw a hideous moccasin snake lying coiled in the grasses almost at my feet a loathsome creature, nearly four feet in length, possessed of a power which rendered his very hideousness strangely attractive. Poisonous snakes have the sort of fascination for us that belongs to scaffolds and guillotines and other means of sudden and violent death. I killed this snake and took him home as a specimen, assuring myself, however, that he was thoroughly dead before placing him in the canoe, where he would not have proved an especially desirable companion had he revived when I was halfway to the shore. A few days later a small water turtle which had come ashore to lay its eggs was found. It had laid one egg in a small hole at the base of a hillock, and another was laid in the canoe. Doubtless there are several kinds of insects on the island, but I found only one species. This was an ant. Probably the ants on this little detached world were more numerous than all the other animals combined. They lived in the only dry spot, a little mound near the centre of the island. Their home was inconspicuous, and might have escaped notice entirely had I not sat down on it! http://plants.ifas.ufl.edu/aqs04-al.html (4 of 6) [6/6/2008 1:50:46 PM]

24(1) AQUAPHYTE To return now to the history of these islands and the part alligators play in building them. These gigantic lizards love to lie in the soft mud at the bottom of lakes; and they carefully select such places in which to hibernate during the colder months. Now, if one could see a "bonnet" lake from which the water had disappeared, it would be noticed that its bottom is a network of interlacing lily-pads. The roots are as large as a man's arm, and it will be readily seen how they would prevent a large alligator from snugly nestling in the oozy mud. The alligator, therefore, prepares his bed by biting and pulling out these roots, and they come floating to the surface, showing plainly the marks of his teeth, to form the framework of a future island. Every stage of its growth could be seen in the "Arm." Numbers of these roots float together and form a kind of raft. A scum collects about it, dust settles upon it, and the whole soon looks like a sheet of mud which undulates with the waves. As it becomes firmer, a small plant, always of the same species, makes its appearance, entirely covering the island, and growing so evenly that one might suppose its seed had been carefully sowed by hand. Later stages are now merely questions of time, but it is probably only a few years before the roots torn from the bed of the lake by the alligator are firmly woven into a compact mass by the grasses and reeds which take possession of it, and we have then an island quite similar to the one I have described. This, it is true, is not a pasture, but it may become one at any time. Some day a strong wind will blow this island ashore-indeed, I saw islands which had been stranded-and then the roots in its bottom will prove living anchors, holding it to its moorings, and by and by the floating island will become firm ground over which cattle cattle may graze. As island after island is blown against this one, the "Arm" recedes, the shore becomes dryer, and ere long it will be firm enough to support cattle which are attracted by its luxuriant growth of grasses. And now what becomes of our villagers? Search the shore as you will, comparatively few traces of them are to be found. Robbed of the isolation of an insular life, they soon disappear to seek new homes where they will be more secure from the attacks of their enemies. The alligator gives place to the cow, the grassy nests of the marsh-rats and neofiber are soon overturned by prying pigs. Coming Soon!

Four Photo-Murals Native Freshwater, and Non-Native Invasive APIRS Lest we forget, with so much current emphasis on invasive non-natives, most plants in the U.S. are native; beneficial to animals, humans, and the environment; and often beautiful. So, here are two photomurals of 76 native freshwater plants of the U.S.. Of the plants depicted, 100% are in Florida; 97% are also found in the rest of the Southeast U.S.; 50% are found in the Eastern U.S.; 22% are found in the West; and 22% are found throughout most of the U.S. Click here for the list of plants featured on the two "native" murals.

24(1) AQUAPHYTE AQUAPHYTE ONLINE SUMMER 2004 44th Annual Aquatic Plant Management Society Meeting A ReportTampa, Florida was the host city for the 44th Annual Aquatic Plant Management Society (APMS) meeting held July 11th 14th. 220 delegates attended, including 18 students, to learn the latest in aquatic plant management from 49 papers and 23 posters. Nine of the presentations were given by students in the annual student paper competition. Seven of the students are working on their Ph.D. and two on their Masters degree. Sarah Habrun of the College of Charleston won the student competition for her presentation, Investigation of a Novel Cyanobacteria Linked to Avian Vacuolar Myelinopathy (AVM). AVM is a fatal bird disease and Ms. Habrun states that the most probable hypothesis is that birds ingest a neurotoxin produced by epiphytic cyanobacteria. The toxic cyanobacteria has been closely associated with Hydrilla verticillata in reservoirs in the southeastern U.S., and has already adversely affected local breeding populations of American bald eagles. All student presenters received a copy of C.D. Sculthorpes The Biology of Aquatic Vascular Plants, or the text of their choice. Linda Nelson and Judy Shearer from the U.S. Army Engineer Research and Development Center, Environmental Laboratory won the poster competition with their poster, Integrating Triclopyr and a Fungal Pathogen (Mycoleptodiscus terrestris) for Control of Eurasian Watermilfoil (Myriophyllum spicatum). The pair received a perfect score from a judging panel of student attendees. A variety of interesting presentations were given, including economic studies, updates on biological and chemical control methods, ecological studies, and a special session on plant resistance and tolerance to aquatic herbicides. Dr. T. Wayne Miller, Jr., founder of the APMS (originally known as the Hyacinth Control Society), presented his recollections from approximately 40 years of aquatic plant management experience beginning in 1960. He displayed a photograph of water hyacinths blocking access to a boat dock in Lee County, Florida from a 1960 edition of The Saturday Evening Post that inspired county commissioners to create the first hyacinth control program in the nation. A review from regional APMS chapters was given, including Florida, Midsouth, Midwest, http://plants.ifas.ufl.edu/aqs04-ap.html (1 of 2) [6/6/2008 1:50:49 PM]
