AQUATIC PLANT MANAGEMENT:
FUTURE CONCERNS

by Tom C. Brown, former Chief, Bureau of Aquatic Plant Management,
Florida Department of Environmental Protection. (Note: Brown resigned as
Bureau Chief during a tussel with legislators this past spring. The following are
excerpts from his last speech presented as Chief to an aquatic plant
management audience.)


At the Bureau of Aquatic Plant Management, we readily admit our
weaknesses, but at the same time we are proud to be a part of the aquatic plant
management profession in Florida. I consider Florida's professionals and programs to be
the best in the world.

We all have tremendous challenges before us as we face the profound environmental and
economic problems being created by invasive nonindigenous plants in Florida. In light of
the crisis, there are at least three major concerns for the future that stand out.

The first concern we have is that the public, along with many of the political leaders of
our state, have not shown any great concern over the crisis being created by invasive
exotic aquatic plants. For whatever reasons, they are in a state of denial. When the
evidence is clear and intelligent people will not accept that evidence, then they are in
psychological denial, and as long as that denial lasts the aquatic ecosystems of this state
will continue to suffer.

Perhaps one reason for the lack of general interest in the problem is the conservation
dilemma posed by invasive exotic aquatic species. I am referring to the fact that the
actions required to "correct" the problems entail the killing or removal of these plants.
Such activities are far less popular than traditional activities related to environmental
protection such as buying land for preservation, mitigation that attempts to create
wetlands, or regulatory activities that are designed to protect threatened and endangered
species. While the public and our leaders profess to support the idea of preserving and
restoring aquatic ecosystems, killing nonindigenous plants in order to accomplish this is




not appealing to them. This negative attitude often causes resistance, not only to the
effective methods available (most of which are the result of outstanding research), but to
the idea that such management is a necessity at all. We often hear someone contend that
when a monospecific stand of invasive exotics is found in a water body, we should just
leave it alone and let "nature" take care of the problem. They forget that "nature" did not
place these plants here, and their co-evolved natural enemies which keep them in balance
in their home range are not present.

Others contend that nothing serious has really happened, that we just have to change the
use we make of that water body. But what use can we make of a lake covered entirely with
topped-out hydrilla? We can't swim in it. We can't fish it. Recreational boating is
impossible. Even flood control and irrigation are adversely affected. In addition, the native
biodiversity is being displaced, and property values are being lowered. Probably the only
ones happy with this situation are the few ducks and coots that feed on hydrilla--a big
price to pay for duck food!

This sometimes agonizingly slow, and sometimes startling rapid attack on biodiversity has
come to be considered "normal", and is therefore largely ignored. Most of the state and its
waters are no longer in a pristine or undisturbed condition. Native species are increasingly
confined to limited spaces, habitat islands with artificial boundaries and conditions. These
spaces were originally influenced by natural processes originating both within and outside
their boundaries. These natural processes have been extensively altered by human
activities. During the coming decades, the populations of invasive exotic species that do
well in these disturbed environments will continue to thrive unless corrective actions are
taken.

A second concern for the future relates to the continued introduction of new invasive
nonindigenous species. Will there be another hydrilla-like exotic to appear in our water
bodies in the future? With the continued importation, sale, and dissemination of
nonindigenous aquatic plants without their first being screened for potential invasiveness,
it is not a question of "if' but "when". It is shocking to see the cavalier attitude with which
nonindigenous species are allowed to be imported into our state. We recognize that most
exotics will never become invasive if they escape into the natural environment, and we
also recognize that some exotics enhance our lives in many ways, not only as food, but
also as things that provide aesthetic values. However that should not keep us from being
concerned about those that do escape and do become invasive. New invasive exotics could
literally cost millions, if not hundreds of millions to eradicate or keep under maintenance




control, and frankly, we do not have the necessary funds to deal with those we already
have.

What value do we place upon our ecosystems? What value do we place upon native
habitat for fish and wildlife? What value do we place upon the loss of the use of our water
bodies for recreational purposes? What value do we place upon irrigation, or flood control,
or even our potable water supply? True, all of these things are difficult to evaluate, but that
does not mean they have no economic value. It is hard to off-set all these costs with the
little profit that is to be had by a special interest group through the sale of invasive
nonindigenous aquatic plant species.

During the past twenty years, millions of dollars have been spent in the programs to bring
invasive exotic aquatic plants under maintenance control, while at the same time virtually
nothing has been spent to prohibit the introduction of additional invasive exotic plant
species. That is the moral equivalent of trying to clean up a water body while you continue
to dump untreated sewage into it. Under present law, there is nothing that can be done
until after an exotic introduction has occurred and proved to be invasive. By that time,
eradication may be impossible and the effects on the environment may be virtually
irreversible.

A third concern we have for the future relates to the funding necessary to bring invasive,
nonindigenous aquatic plants under maintenance control, including the funding for the
necessary related research that must be done. For many reasons, our costs are escalating
dramatically. For example, every year funding for management activities remains low,
new infestations occur and existing infestations expand, dramatically increasing the costs
of achieving or restoring maintenance control. Also, in the past ten years there has been a
70% increase in herbicide and mechanical harvester costs. Add to this the loss of federal
funds and you have the makings of a real environmental catastrophe.

We have estimated that the funding needed for hydrilla alone for this fiscal year to be
about $13 million. [But the Bureau received only about a tenth of that...Ed.] At present,
water hyacinth and water lettuce are under maintenance control, and hydrilla is under
maintenance control in about 30 of our large public water bodies. We estimate that the
total acres of hydrilla remaining in public waters to be about 45,000 acres--down from
about 100,000 acres of two years ago. This is impressive progress which soon could be
lost.




At the same time that invasive aquatic plant problems are being under funded, both the
public and political leaders are focused on water quality issues. The irony is that we may
spend millions, if not hundreds of millions as in the case of the Everglades, to improve
water quality, only to find that the beneficiaries of that improvement are the invasive
exotics that are destroying our biodiversity and negatively impacting the economy of the
state by millions of dollars annually.

These three concerns constitute what I believe is a formula for the creation of an
environmental disaster: an uninformed and uncaring public; a cavalier attitude regarding
the introduction of invasive exotic plant species; and an unwillingness on the part of
government to commit the funds necessary to avert this tragedy.

Will the Rare Aquatic Carnivorous Plant Aldrovanda
vesiculosa Survive in Europe?


by Lubomir Adamec, Institute of Botany of the Academy of Sciences of the Czech Republic,
Section of Plant Ecology, Dukelska 145, CZ-379 82 Trebon, Czech Republic. E-mail:
adamec(a@butbn. cas. cz

The waterwheel plant, Aldrovanda vesiculosa L. (Droseraceae), is a very rare aquatic
carnivorous plant that is rapidly vanishing from Europe. Yet it is spread over a vast
territory throughout the Old World. It is a rootless plant, usually 6-18 cm long, free-floating
just below the water surface. It has always excited curiosity among botanists due to its
attractive snapping traps (3-6 mm long). Aldrovanda has the same life form and growth
strategy as temperate aquatic Utricularia species: a fast apical growth (1-2 whorls a day)
and simultaneous basal decay. In temperate countries, it propagates only by apical branching
of shoots. Apical winter buds (turions) are formed in autumn.


Distribution
Aldrovanda is spread irregularly and sparsely from temperate to tropical zones from Europe
to Australia. The origin of its recent population in Europe is still unclear. Here, on the basis


4




of palaeontological records, it is usually considered a Tertiary relict. Since its turions
probably are spread by migratory waterfowl to new sites, another theory explains the origin
of its European temperate populations as postglacial naturalization of African plants that
were transported by birds. In any case, the historical postglacial spread of Aldrovanda in
Europe was highly irregular, variable in time and area, and probably dependent on migratory
routes of waterfowl. Recent data on its distribution in Africa and Asia are not available
(except for Japan) and only a few recent sites are known from Australia. In Europe, it
occurred more frequently and was recorded at about 150 sites in the last two centuries.
However, the view on the recent map of its sites is alarming. It has declined dramatically in
the last 30 years, vanishing from Germany, France, Italy, and Slovakia. It is now probable
that Europe (excluding the former USSR) has no more than 15-20 sites, with a few dozen
sites in the Ukraine and Russia. There are ten sites still in Poland (from a previous record of
78), one in Hungary, and possibly, a very few in the Balcans. Two artificial sites are in
Switzerland where it was successfully introduced in 1908. In all European countries, it has
had a status of "critically endangered species" and has been under strict state protection for
at least twenty years. Yet, this has not helped much!

Ecological Requirements and Reasons for Decline
Aldrovanda is highly sensitive to competition with filamentous algae and higher aquatic
plants that form denser stands. Very fast apical growth and vegetative propagation are the
only way to overcome the competition. The most important ecological requirements of
Aldrovanda include: a) free-C02 concentration >0.1 mM as the plant is a strict C02 user;
pH may be within 5.0-7.6; b) a medium humic acid concentration (2-30 mg.1-1); c) high
biomass of plant litter from reeds or sedges; d) water surface free of a dense biomass of
submersed or floating macrophytes; e) transparent water free of suspended matter or
phytoplankton; f) relative irradiance >20 % of full sun; g) relatively warm water in summer
(optimum 25-28oC); h) shallow water (0.15-0.6 m, but summer minimum 5-10 cm); i)
abundant zooplankton as prey; j) oligo-mesotrophic water.

Aldrovanda grows in shallow standing dystrophic waters: lakes, bogs, fens, backwater
pools, and peaty fishponds, usually on very limited plots in wind-exposed littorals. It never
grows in open water, but only in shallow, loose stands of emergent vegetation (Phragmites,
Typha, Carex) or in little bays among tussocks of denser vegetation. The strict habitat
requirements of Aldrovanda characterize it as a stenotopic species. Its preferred sites are
those subject to slow, permanent succession wherein the emergent vegetation becomes
dense. Generally, small habitat changes may result in the decline of Aldrovanda. That is
why its occurrence at a site usually is limited in time and it may be found at other proximate
site(s) where favourable conditions have developed (a "fugitive strategy"). In the last
decades, however, the number of potential suitable sites has decreased drastically in many
European countries and its chance to "jump" to new sites has greatly diminished. Its rapid
decline has been caused mainly by water eutrophication, drainage, and filling in of water




bodies. Other reasons may be more general land-use changes, particularly intensive
agriculture, water level fluctuations, and wetland afforestation. Besides the evident reasons,
high amounts of N03-, NH4+, and SO042- in acid precipitates might accelerate
eutrophication and, hence, native succession of shallow wetlands. This is suspected because
Aldrovanda has been vanishing even from those sites which are evidently quite unimpacted
by man. Also, the velocity of its decline has been much higher within the last 30 years than
before.

Active Protection Selection of New Sites
Elaboration of reliable outdoor culture of Aldrovanda was a necessary prerequisite for both
ecophysiological study and selection of its suitable substitute sites in the Czech Republic.
The culture mimics habitat conditions at natural sites. In a 1-2.5 m2 plastic container, about
a 3 cm layer of litter of Carex gracilis (or similar species), placed over 5-8 cm of sand, is
used as the bottom substrate. The container is loosely planted with sedges or common reed.
Water depth is 20-30 cm. As Aldrovanda is susceptible to boron deficiency, boric acid must
be added. Turions overwinter well in the refrigerator.

Great effort has been made to select new suitable sites in the Czech Republic. The plants
placed in nylon enclosures in three shallow dystrophic wetlands in North and South
Bohemia grew rapidly and reproduced 8-34 times over the 1994 season. Approximately 10-
50% of the turions overwintered. When 30 Aldrovanda plants were introduced to the
suitable sites in South Bohemia in 1995, the plants grew rapidly only in the Carex rostrata-
dominated pool at Pta i blato 1C. However, turions overwintered perfectly and in the 1996-
1997 seasons, the plants propagated richly, forming an abundant population. The character
of the suitable pools at Pta i blato reminds us of some natural Polish sites. Water level at the
sites in summer has been found to be the crucial factor for rapid growth and propagation of
Aldrovanda. Both of the dystrophic sites are firmly connected with hypereutrophic
fishponds with fluctuating water levels due to summer rains. The water level was very low
in 1995, but high in 1996 and 1997.

Thus, a new prolific site arose in South Bohemia, where Aldrovanda had never grown.
However, this success should be accepted cautiously as the suitable pools tend towards
eutrophication and overgrowing and some management will be necessary in future years to
keep up its rich population. Similar introduction of Aldrovanda succeeded in Switzerland as
early as 1908 and a stable population has been growing there since. Nowadays, when its
natural spread by waterfowl within vast areas of Europe is almost excluded and its natural
populations are declining, introduction to new sites is probably the only effective way to
keep and propagate the European population, in spite of some success with growing it in
tissue culture.

To increase the feasibility of introductions of Aldrovanda to new sites, it is essential to grow




it in outdoor culture, e.g. in botanical gardens or research institutes (so far T ebo Wroclaw,
Berlin, Kiel, Arras, and Strasbourg) and select potential sites. It also might be a project for
Nature Conservation Unions. These organizations in European countries are challenged to
consider their participation in the conservation of Aldrovanda. I am able to provide them
with sufficient plant material for cultivation as well as know-how. Aldrovanda is still
waiting ...!

Note: The author asks colleagues working in Africa to please send living plants or
seeds of Aldrovanda to the above address. The study of African plants could provide
more clues to the origin of European populations. Any information on recent African
spread of Aldrovanda is greatly welcome.

Cyperus Weeds ALERT


Here are four more exotic aquatic Cyperus weed species which now occur
in Florida, and aquatic plant managers should "be on the lookout" for them. Two of
these sedges are listed by Holm (1977) as being among the world's worst weeds
(along with water hyacinth, hydrilla and others). Dr. Charles T. Bryson, an expert on
the Cyperaceae, recently contributed photographs and plant material of these species
to APIRS. Bryson is with the United States Department of Agriculture, Agricultural
Research Service (USDA-ARS), Southern Weed Science Research Unit, Stoneville,
Mississippi 38776-0350, 601-686-5259. E-mail: cbryson(ag.gov


Cyperus alopecuroides Rottb. (Juncellus alopecuroides (Rottb.) C.B. Clarke)


C. alopecuroides is a huge sedge discovered in a reclaimed wetland near Fort
Meade (Polk County), Florida. This is only the second finding of this impressive
species in the Western Hemisphere. C. alopecuroides grows up to twelve feet tall,
with bracts up to six feet long! It has broad bracts and leaf blades and a branched




inflorescence with spikes of densely clustered golden-brown spikelets. Its leaf
margins are serrated and sharp. This species is widely distributed in the tropics of
the Old World where it may form extensive stands and floating mats. According to
Bryson, of the four species discussed here, this one likely would become the most
troublesome weed in Florida conditions.


Cyperus iria L., rice flatsedge


Rice flatsedge, is in Holm's list of the world's worst weeds. An Asiatic species, it
was probably introduced in the 1700 or 1800s. Rice flatsedge has become common
throughout the southeastern United States. Once established in wet situations, rice
flatsedge can persist without wet feet, and become a major weed in rice, cotton,
soybean and other crops.


Cyperus difformis L., smallflower umbrella sedge



















Smallflower umbrella sedge, is listed in Holm's list of the world's worst weeds,
being a problem especially in rice, sugarcane, tea and corn. Smallflower umbrella
sedge is native to the tropics of the Old World, but is spreading well outside its
native range. This sedge has a relatively short generation period of as little as 4 to 6
weeks from seed to seed as opposed to a more usual one or two generations a year:
Bryson notes that such a short life cycle is more like that of an insect than a plant.
Smallflower umbrella sedge seems to be spreading along major waterways and in
rice production areas of the U.S. In California, this plant has become resistant to
rice-field herbicides. In Asian rice production, where herbicides are not used, this
weed may account for 60-70% of the total biomass of the rice field.


Cyperus prolifer Lam., dwarf papyrus or miniature papyrus

































Dwarf papyrus is commonly sold as an ornamental for use in water gardens,
similar to papyrus (Cyperus papyrus L.), and false papyrus (Cyperus involucratus
Poir.). This species spreads vegetatively, simply by leaning over. New daughter
plants grow in the inflorescence; as the new shoots become heavier, the mother
plant leans over, eventually reaching the mud whereupon the daughter plants attach,
grow and spread. In central Florida, this sedge apparently has escaped from
cultivation and is found growing in floating mats and along margins of limesink
lakes.

Questionnaire Results



Looking for someone who speaks Spanish and studies Azolla? Or a field
research contact in New Zealand? The last issue of AQUAPHYTE contained a
questionnaire for personnel in aquatic plant research and management with the
purpose of compiling a searchable database of this group. The project was
performed in conjunction with the Aquatic Plant Management Society, Inc.
(APMS). Over 1,200 people responded to the questionnaire and the database is now
available for searching. Any field from the questionnaire can be searched, including
name, address, languages spoken, fields of expertise (subjects, plants, countries),
employer, etc. The database contains other essential information such as telephone
and fax numbers, E-mail addresses and WWW/Internet sites. For searches of the
Database of Personnel in Aquatic Plant Research and Management, contact APIRS
or Dr. Alison Fox, APMS President, University of Florida, Agronomy Department,
POB 110500, Gainesville, FL 32611 USA, 352/392-1808, E-mail: amfox(gnv.ifas.
ufl.edu

All respondents to the questionnaire were entered into a drawing at the annual
APMS meeting for a complete set of the Journal ofAquatic Plant Management
(1962-1996). The winner was Dr. Michael Braverman, Department of Plant
Pathology and Crop Physiology, Louisiana State University, Baton Rouge,
Louisiana. (According to the database, he speaks Thai.)

The last issue of AQUAPHYTE (VOL. 16 NO. 1) also required a subscription
renewal for continued receipt of this free newsletter. Over 1,200 aquatic and
wetland plant managers, researchers, students and others renewed their subscription
to our publication. Please remember that AQUAPHYTE is a unique forum for this
specialized group of researchers and managers. We encourage the submission of
news and articles of interest to our readers.

Notable Quote:


The words "obnoxious aquatic plants" conjures up visions of waterways,
rivers, streams, and their tributaries, all choked with water hyacinth, alligatorweed,
hydrilla, Eurasian
watermilfoil and
many, many other
species of
undesirable aquatic
plants. The vision ..h '"
would not be
complete if we did
not include the
many boats and
barges stuck in the
vegetation and
moving with
vegetation as
directed by the
wind; or the flood
waters which are being retained on land areas because floodways are choked with aquatic
vegetation; or the agricultural crops suffering extensive damages because of the lengthy
periods of flooding resulting from clogged drains choked with aquatics; or the untold
losses to wildlife and fisheries as a result of coverage of open waters and blanketing of
marshlands by obnoxious plants; or the reduced flows of life-giving water in choked
irrigation ditches. We must not forget these visions because they can become reality again
in short order if neglected."

Turf, July 1972.

Digital Floristic Synthesis of North America

Diskettes for Windows 95 or 3.1, produduced by the Biota of North America Program, University
of North Carolina

Thirty-six thousand (36,000) species are included in this monumental new
computer version of the standard plant reference for U.S. federal agencies: the
Synonymized Checklist of the Vascular Flora of the United States, Canada and
Greenland by Dr. John T. Kartesz. The computer version, however, contains much
more information than the printed version.

This PC/Windows computer program provides plant nomenclature, taxonomy,
geography, morphology and other information distilled from nearly 300 years of
North American vascular plant systematic research. Linking nearly 500,000 records
of plant distributions, this software enables taxonomists, horticulturalists,
nurserymen, foresters, plant and wildlife managers, ecologists and others to produce
species checklists and distribution summaries, and assessments of species
morphology, species rarity, species endemism, species nativity, etc.

Plants can be selected by scientific and common names or by choosing any of 45
biological attributes. The user-friendly systems permits complicated Boolean
operations to be performed with the click of a mouse, and displays the results
graphically as distribution maps.

Though originally advertised as four products, the producers have decided to
include all parts on a single CD. The single CD is for sale for $495.00.

Lexicon

The Lexicon enables users to show immediate relationships between taxa at various
ranks and to produce listings of all plant names in current use. This product uses the




International Code of Botanical Nomenclature for spelling and orthography.

Floristic Atlas

The Atlas displays state level distribution maps for 28,000 accepted taxa, allowing
the maps to be printed in publication-quality format, black and white or color. Zoom
capabilities will permit county-level and even site-specific data to be added to future
editions of the Atlas. A county data update is planned to be released in the summer
of 1998.

Biological Attributes

This includes up to 45 biological attributes for each of the 36,000 species, including
morphology and other specialized data, such as rarity, weediness, insectivory, habit,
habitat, trophic levels, duration, medicinal value, forage and range values, toxicity,
etc.

AQUATIC AND WETLAND PLANTS OF NORTHEASTERN NORTH AMERICA,
by Garrett E. Crow (University of New Hampshire) and C. Barre Hellquist,
Massachusettes College of Liberal Arts. 1999.
(Pre-publication discount and ordering information from Mr. Steve Salemson, Associate
Director, The University of Wisconsin Press, 2537 Daniels Street, Madison, WI 53718-
6772. Phone: (608) 224-3889, Fax: (608) 224-3924. E-mail: salemson@facstaff.wisc.edu)

Currently "in press", this all new 2-volume reference includes 1139 plant species,
with 92% of the taxa illustrated. The aim of this work is to aid in the identification
of vascular plants which are native or have become naturalized in aquatic and
wetland habitats in the northeast. The range of the manual covers Newfoundland to
Minnesota, south to Virginia and Missouri. The keys treat a total of 1139 species
(1186 taxa) representing 295 genera in 109 families. To aid the users 606 pages of
illustrations include figures of 1086 taxa, with 93% of the taxa fully or partially
illustrated. To further facilitate the identification process, references to the figures
are incorporated into the keys. Volume 1 contains the Introduction, Nuisance
Aquatic Plants of the Northeast, General Keys, Pteridosperms, Gymnosperms and
Angiosperms/Dicots. Volume 2 contains the Angiosperms/Monocots. Both volumes
will have a full index.


FLORIDA WETLAND PLANTS--AN IDENTIFICATION MANUAL by J.D. Tobe,
K.C. Burks, R.W. Cantrell, et al. of the Florida Department of Environmental Protection.
1998. 598 pp.
(Order from IFAS Publications, POB 110011, Gainesville, FL 32611-0011. Phone: (352)
392-1764, Fax: (352) 392-2628. $35 plus S/H. Credit card ordering: 1-800-226-1764
weekdays during business hours.)

With more than 800 color photos and 1,000 entries, this book covers a majority of
the plant species listed in the Florida Wetland Delineation Methodology, 1994




(Chapter 62-340, F.A.C.). This is the latest "must have" new resource to help
understand, appreciate and protect Florida's wetlands. It will appeal to nature lovers
and other outdoorspeople, as well as to regulators, scientists, consultants and others
who must help determine where wetlands lay. The volume is a completely revised
and rewritten update to the Identification Manual for Wetland Plant Species of
Florida, published in 1987.

Plants are treated in one-page descriptions which include plant morphology, tips for
recognizing the species, habitat descriptions and Florida distribution. The color
photographs are reproduced well and the drawings are adequate.

Each plant is placed into one of four "indicator" categories: Obligate, Facultative
Wet, Facultative, and Upland; however, the book contains no definitions for what
these terms mean, nor does it include Florida's wetlands delineation laws and plant
lists. Nor does the book include a key to the plants, nor some other means to help
non-botanists identify plants, such as are included in commonly-used field guides.
With this manual, the user is simply expected to know what plant family the plant of
interest is in, and then flip the pages until accidentally finding a matching picture or
drawing. This can be a particular irksome procedure when considering Cyperaceae
(44 pages of plants) or Poaceae (86 pages). In addition, submersed aquatic plants are
not included in the book, since they are excluded from the wetlands vegetation
index.

4. MALARIA PREVENTION IN THE PLANNING OF IRRIGATION SYSTEMS,
by Blue Nile Associates. 1995. Various pages.
(Order from Blue Nile Associates, POB 552, Dolores, CO 81323. 970-882-7778. E-mail:
bluenile(gmcimail.com Handbook 2: $25. Handbook 3: $50. Handbook 4: $30.)

More than 200 million people are infected with bilharzia worms (schistosomiasis).
This human disease is spread by aquatic snails living in rivers, canals, ditches and
other water bodies. The number of snails is linked to the amount of aquatic plants
present; plants serve as the snails' food and sites for egg deposition. Blue Nile
Associates are consultants on tropical diseases in water resource development
projects. Written especially for parasitologists and engineers, these handbooks
contain guidelines for designing tropical dams and irrigation systems to avoid health
problems. They also contain detailed 1995 cost information on disease control
measures, useful in planning and teaching.

aquatic. Numerous tables describe plant habitats and water chemistry.


AQUARIENPFLANZEN, by C. Kasselmann. 1995. 472 pp.
(Order from Verlag Eugen Ulmer, Stuttgart.)

This book is for aquarium plant lovers, who read German. The book treats more
than 300 aquatic and wetland plants; each treatment includes a high quality color
photograph (mostly very good field shots), taxonomy, distribution, plant description,
culturing requirements and ecology. According to C.D.K.Cook, "the book is a
thoroughly professional work and deserves a wider readership than just German-
speaking aquarium freaks."


THE RIVER SCENE--Ecology and cultural heritage, by S.M. Haslam, with
contributions from J. Purseglove and G.A. Wait. 1997. 344 pp.
(Order from Cambridge University Press, The Edinburgh Building, Cambridge CB2 2RU,
United Kingdom; 40 West 20th Street, New York, NY 10011-4211; 10 Stamford Road,
Oakleigh, Victoria 3166, Australia.)

Sylvia Haslam loves rivers: "Rivers are much too unprotected and vulnerable. The
loss of water and the loss of wildlife and cultural heritage, have become
unacceptable... River integrity has no one to speak for it." In this, her latest book
about rivers, she seeks to help non-specialists understand rivers by presenting some
shouldd" of rivers in their natural environment ("rivers should have much
diversity", etc.) and of rivers in relation to their cultural heritage (rivers should not
look like industrial refuse zones). The copiously illustrated book "aims to give a
wide view and an overview", looking at rivers in terms of water, structure,
vegetation, pollution, birds, cultural heritage and controlled recreation, omitting
information about invertebrates, fish, chemistry, diatoms, other algae and micro-
organisms. Though the book concentrates on British rivers, the lessons and
shouldd" apply to rivers worldwide.





BIOLOGICAL POLLUTION -- The Control and Impact of Invasive Exotic Species,
edited by Bill N. McKnight. 1993. 261 pp.
(Order from Purdue University Press, 1532 South Campus Courts Bldg E, West Lafayette,
IN 47907-1532. 317-494-2038; 1-800-933-9637. $30 plus S/H.)

"Biological pollution is one of the least publicized environmental issues facing us,"
says the editor. This is the proceedings of a symposium held at Indiana University-
Purdue University at Indianapolis, October 25-26, 1991. It includes 21 reviews and
case studies covering invasive species as diverse as funguses, fish, fire ants,
domestic cats, and aquatic plants. "What role can science play in eliminating or

Washington, DC 20055. 1-800-624-6242. WWW: http://www.nap.edu US$39.95
hardbound.)

Ballast is any solid or liquid that is taken aboard ship to achieve more controlled and
safer operation. It has been estimated that more than 3,000 species of animals and
plants are transported daily around the world in ballast water, including species such
as zebra mussels, comb jellyfish, seagrasses, and possibly freshwater plants. When
these species are released in new areas, well-known ecological problems can result.
This book assesses current approaches to the problem and makes recommendations
for U.S. government agencies and the international maritime industry.


STRANGERS IN PARADISE--Impact and Management of Nonindigenous Species

(Order from Island Press, Box 7, Dept. 2PR, Covelo, CA 95428. 800-828-1302. US
$29.95.)





In Florida, millions of acres of land and water have been invaded by non-native
plants and animals. Does this mean that introduction of all non-native species should
be regulated? Including plants that nobody thinks will ever spread and become
invasive? "Well,...yes!" the editors of this book say. It "provides the first
comprehensive in-depth examination of the Florida experience." Chapters include
"case studies" of nonindigenous insects, invertebrates, fishes, amphibians and
reptiles, birds and mammals; examples of various "management strategies"; policy
and implementation discussions; and essays on the roles of federal and state
governments.

LAS TABLAS DE DAIMIEL--Ecologia Acuatica y Sociedad, edited by M. Alvarez
Cobelas and S. Cirujano. 1996. 371 pp. (In Spanish.)
(Order from Direccion General de Conservacion de la Naturaleza, Organismo Autonomo
Parques Nacionlaes, Servicio de Publicaciones, Gran Via de San Francisco 4, 28005
Madrid, SPAIN. US$21.00 plus S/H. Fax: (91)3476303.)




Las Tablas de Daimiel is a 1700 hectare wetland found on the La Mancha plain of
south-central Spain. "It is experiencing very high organic pollution coming from the
towns in its watershed." Macrophyte vegetation species richness has decreased from
25 species reported in 1974 to 15 species reported in 1995; fish species have
declined from 13 species twenty years ago to 2 species today. Although humans
have lived at Las Tablas for the past 3,600 years, data shows that in only 20 years
man has overexploited Las Tablas and in doing so, reduced its area by two thirds.
The Spanish government is determined to restore and conserve Las Tablas. This
book compiles what is known about the area's morphology and climate, water
chemistry and production, as well as man's impacts on these unique wetlands.


FLORIDA AQUACULTURE PLAN, Current Status, Opportunities and Future

PEATLANDS IN FINLAND, edited by Harri Vasander. 1996. 168 pp. (In English.)
(Order from the Finnish Peatland Society, Kuokkalantie 4, FIN-40420, Jyska, Finland.
About US$40.)

Finland's 10 million hectares of peatlands are "a major and fascinating element of
the Finnish landscape and national economy." Since the Stone Age, peat, which is
made of fragmented plant residues, has been used for the production of energy. As
peat has been cut-away and burned, peatlands have been converted to agriculture and
forestry. This handsome and colorful book, an "updated interdisciplinary review", is
filled with pictures, illustrations and maps, and includes sections on the ecology and
natural history of Finnish peatlands, Finland's peat resources, economic utilization
of peatlands, environmental aspects of peatland utilization, and options for

least much of the year, with water.


RESTORING PRAIRIE WETLANDS--An Ecological Approach, by Susan M.
Galatowitsch and Arnold G. Van der Valk. 1994. 246 pp.
(Order from Iowa State University Press, 2121 S. State Avenue, Ames, Iowa 50014-8300;
1-800-862-6657. $44.95 plus S/H.)

This book "describes and assesses ecological-based methods of restoration in the
southern prairie pothole region--Iowa, Minnesota, and South Dakota." The main
problem discussed by this book is whether or not "restored" wetlands function as the
original wetlands did, and what difference it makes if they do not. The book
examines ecological and technical considerations in planning, constructing,
managing and evaluating wetland restorations. It includes plant, animal and soils
lists of the pothole region.


BIOLOGIC AND ECONOMIC ASSESSMENT OF BENEFITS FROM USE OF
PHENOXY HERBICIDES IN THE UNITED STATES, edited by Orvin C. Burnside.
1996. 227 pp.
(Ordering information unknown. However, the entire book can be accessed via WWW:
http://piked2.agn.uiuc.edu/piap/phenoxy.html The section on use of 2,4-D in aquatic
systems, written by Dr. Carole Lembi can be found at http://piked2.agn.uiuc.edu/piap/
assess2/chl2.htm

This report was prepared by a dozen of the world's authorities on phenoxy
herbicides, such as 2,4-D. The work was sponsored by the National Agricultural
Pesticide Impact Assessment Program (NAPIAP), a USDA and state cooperative
program. It includes chapters on the history of 2,4-D, risk assessment, potential
effects of banning phenoxy herbicides, and the use of phenoxy herbicides in
agriculture, forestry and aquatic systems. The book also includes "An Overview of
the Epidemiology and Toxicology Data", which is a thorough review of 74 scientific
papers and case-studies of the effects of phenoxy herbicides on animals and humans.
