Aquatic Plant Information Retrieval System
The Aquatic Plant Information Retrieval System (APIRS),
now with more than 67,000 bibliographic citations, continues to be
the largest free database of its kind in the world. Used regularly by
researchers, government agencies, companies, teachers, students
and private groups and individuals, users can request searches of
the database or they can access the database themselves online.
APIRS is supported by the Florida Department of Environmental
Protection, Bureau of Invasive Plant Management.
The APIRS database was moved to a new system programmed-
by a senior computer science student at the University of Florida,
Mr. Dmytro Martynyuk. The system now runs on MySQL with
php as an interface, allowing for greater flexibility and stability
Features of the new system include an optional Log In that en-
ables users to tag and email citations, a date modifier field, faster
data entry, online editing capabilities, and a far less expensive
system to maintain.
To tag and email citations, users simply login before searching
the database (nothing is required except a password and an email
address). Any citations of interest may then be selected and sent
to Tag Records, where you may accumulate or delete citations
before sending them to your own email address. See Tagging
Help under Search Strategies for more information (only avail-
able when you log in).
Note: Logging in is not required in order to search the APIRS
database. It is only required for tagging citations.
Search operators for the APIRS database have changed and are

= Truncation operator. An asterisk (*) appended to a
word will find that word plus any additional letters; for example:
sediment* will return records on sediments, sedimentation, sedi-
+ = AND Operator. A leading plus sign (+) indicates that the
word or words must be present in each citation that is returned.
There is no space between the operator and the search term; for
example, +hydrilla +smith

the word must not be present in any of the citations that are re-
turned; for example, smith* -hydrilla will return citations contain-
ing smith, but not those containing hydrilla.
= OR operator. When neither + nor is specified, the default
is OR; for example, smith* hydrilla* returns citations that contain

To restrict your search results by date, choose one of the modi-
fiers from the Date modifier field (<, >, =), and enter a date, com-
bined with your search term in Search All Fields.
To search for a single publication year, enter the year into the
Date field under the list of individual fields (see below).
+hydrilla smith finds citations that contain the word "hydril-
la", but ranks citations higher if they also contain Snniit ".
+ = BUT NOT operator. +wetland -construct* finds cita-
tions that contain "wetland" but not "constructed wetlands".
Search Individual Fields
To search a specific field (for example, Title, Author, Date,
etc.), type a single word into an individual field. Individual field
searches do not support the above listed operators, multiple search
terms, or multiple fields; use a single word in a single field only
(for example: Vallisneria in the Title field).
Advanced Search Examples
Following are examples of advanced search strings for search-
ing the APIRS database. These have been compiled based on
many years of experience using the database. Search examples
are in bold:
For acid rain, use the following keywords to be sure you are
not missing the publications that refer to acid rain as acid precipi-
tation or acid deposition: +acid +(rain* precip* depositi)
For carbon-14, search: ("c-14" "c14" "14-c" "14c" "carbon-

Mr. Moran is curator of ferns at the New York Botanical Garden and the author of four other books about ferns. This book is orga-
nized into six categories: The Life Cycle of Ferns; Classification of Ferns; Fern Fossils; Adaptations by Ferns; Fern Geography, and
Ferns and People. Aquatic genera include Azolla, Ceratopteris, Equisetum, Isoetes, Lygodium, Marsilea, Salvinia (with the chapter
title, The Molesting Salvinia), and others. The book is full of _.ia. kil natural history, such as the quote from 19th century botanical
explorer Richard Spruce who, upon sighting a stand of giant I ,,,, .-i., ;i z. (Equisetum) in Ecuador in the early 1860s exclaimed, "the most
remarkable plant in the forest of Canelos is a gigantic Equisetum, 20 feet high, and the stem nearly as thick as the wrist!...It extends for
a distance of a mile on a plain bordering the Pastasa [Pastaza River] but elevated some 200 feet above it, where at every few steps one
sinks over the knees in black, white, and red mud." There are literary references from h..l .. "..-. to Daniel Defoe's Robinson Crusoe.

This introductory book describes the Ruidera lakes, made up of a chain of lake basins in Campo de Montiel in Central Spain. The
lakes depend on groundwater and surface drainage for their water. Similar lake districts occur in Plitvice (Croatia), Land'o'Lakes (Wis-
consin), the Adirondack mountains (New York) and the northwest region of Florida (Tallahassee). Human activities have dramatically
altered the environmental quality of the Ruidera lakes.
Forty-five aquatic macrophytes are listed in the chapter devoted to this topic, nine of which are Charophytes.
BAIRA: THE FLOATING GARDENS FOR SUSTAINABLE LIVELIHOOD
By Haseeb Md. Irfanullah, with contributions by Md. Belayet Hussain and T.I. ( i.'n .l. / ,,,; edited by A. Nishat and R. Ahmed, 2005.
61 pp. ISBN 984-8574-08-5. IUCN-The World Conservation Union, Bangladesh Country Office, Dhaka.
This intriguing book describes bairas, floating platforms made up of plant materials, used to cultivate crops or to raise seedlings
within ',, (small containers made with aquatic plant material). Water hyacinth (Eichhornia crassipes) plants are the major component
of these practical structures. Since the floodplains of southern Bangladesh are under water for three to four months per year, bairas are
an effective method of creating small tracts of arable land. At the end of the wet season, bairas can be broken up and used for compost.
This book was written as part of a project to provide alternative livelihood options to the people of Bangladesh.

Pictured on the cover of this US Airways magazine is
the infamous Salvinia molesta. The issue was discovered
by Mr. Don Doggett of the Lee County Hyacinth Control
District (Florida) as he was flying to the annual meeting
of the Aquatic Plant Management Society in Portland,
Oregon last year. Also in the photograph is another well-
known aquatic weed, Eichhornia crassipes. Fortunately
these invaders are enclosed in an ornamental pond on an
island, and neither species can survive in salt water. But it
is well known that aquatic weed infestation problems often
begin when an attractive, conspicuous lavender flower and
unknowing tourists are involved.
Eichhornia crassipes (water hyacinth) has long been
cited as one of the ten worst weeds in the world. It wreaks
havoc in the world's great rivers, irrigation and flood con-
trol canals, and reservoirs. A mat of medium-sized plants
may contain as many as two million plants per hectare and
the total wet weight may be 270 to 440 metric tons per
hectare (Holm (1977)).
Salvinia molesta, a serious weed in approximately two
dozen countries, is known to foul irrigation systems and
navigable streams, interfere with electric power produc-
tion, and threaten rice farming.

Eurasian Watermilfoil in Idaho
by William T. Haller, Acting Director,
UF/IFAS, Center for Aquatic and Invasive Plants
In April of 2006, the Idaho legislature allocated four million
dollars per year for a three year effort towards eradication of
Eurasian watermilfoil (EWM), Myriophyllum spicatum, in their
freshwater systems. EWM was located primarily in the large
lakes (reservoirs) of northern Idaho and in many small lakes in
the southwest, near Boise. The funding program was directed by
the Idaho State Department of Agriculture (ISDA), which uti-
lized lake associations, county noxious weed programs, coopera-
tive weed management associations, and Native American tribes,
as contracting authorities to conduct the effort. By the summer
of 2006, hand removal, benthic barriers and herbicides, as well
as educational programs, were all being utilized to reduce EWM
populations in the state.
In November 2006, a peer review panel was established to
evaluate and make programmatic recommendations to the ISDA
to streamline the program and make it more efficient. The panel
was chaired by Dr. Joe Joyce, former U.S. Army Corps of Engi-
neers, Director of Weed Control Operations for the Jacksonville
District, and currently Executive Associate Vice President for
Agriculture and Natural Resources at UF/IFAS. Panel members
also included Dr. Ken Langeland, UF/IFAS, Dr. Robert Leavitt,
California Department of Food and Agriculture, Mr. Chip Well-
ing, Minnesota Department of Natural Resources, and Mr. Jeff
Schardt, Florida Department of Environmental Protection. The
panel convened November 12-16, 2006 in Boise, Idaho, and met
with numerous state agency personnel and county noxious weed
superintendents, as well as many stakeholders, in order to review
the eradication efforts. The full report is available at http://www.
The panel was complimentary of the 2006 eradication pro-
gram, a monumental effort to establish a program where none
had existed in order to treat EWM in the summer of 2006. The
panel discussed eradication at length, recognizing that there is no
effort to control EWM in many waterways in eastern Washington
state, a close source of plants for reinfestation. The conclusion
was to eradicate EWM in counties with small infestations where
eradication is possible, and to control EWM around boat ramps
and in high use areas in large reservoirs (where eradication is
less likely) to minimize movement into nearby waters. The panel
also recognized the ISDA as the lead agency, and endorsed the
county based weed management agencies as primary operational
entities. Following this initial three year effort, additional recur-
ring funding should be sought to maintain the effort against not
only EWM, but other potentially invasive aquatic weeds. Addi-
tional staffing was deemed necessary to represent north, central
and southern Idaho in program coordination, mapping, survey-
ing and evaluation of contractor performance.
Most invasive weed management programs identify a prob-
lem, followed by many years of cajoling agency heads and legis-
lators to provide funds for control. For example, for many years

Florida biologists recognized melaleuca (Melaleuca quin-
quenervia) as a significant and expanding problem in south
Florida. Finally in about 1990, funds were allocated and
15-17 years later, melaleuca is under control in most areas
and eradicated from many sites. In Idaho, funding was pro-
vided by an informed legislature, which is being followed
by program development and new proposed legislation to
reduce the risk of naturalization of additional species and
provide greater vigilance in natural and aquatic areas.
In the southeastern U.S., Florida in particular, we have
new invasive pests found on a regular basis. There are
certainly many invasive weeds in Idaho (cheatgrass (Bromus
tectorum) and Russion olive (Elaeagnus angustifolia)) that
are very common and very serious, but aquatic ecosystems
in Idaho only contain the aquatic weeds EWM and curly-
leaf pondweed (Potamogeton crispus), with a huge
diversity of native species. Hopefully the state of Idaho,
with a program and personnel in place, can protect their
aquatic systems from further invasive aquatic plants.

International Aquatic Plant Enthusiasts Gather
in Thailand by Paula Biles
The annual Symposium of the International Waterlily & Water Gardening Society (IWGS) convened in Asia for the
first time in the Society's 23 year history. The July 2007 meeting's activities spanned seven days and was attended by
scholars, hybridizers, retailers, botanical garden directors, growers, and hobbyists from 14 countries.
Several Thai agencies co-hosted the Symposium, which was considered part of the national celebration to honor the 80th
birthday of King Bhumibol Adulyadej. Our hosts included Kasetsart University, King Rama IX Public Park, the Thailand
Agricultural Science Foundation, and Queen Sirikit Botanic Gardens. They pulled out all the stops to showcase the aquatic
plant side of the country, as well as to show attendees a good time while exposing us to fascinating non-botanical things.
A perfect example of our royal treatment was that their beloved Thai Princess Chulabhorn Walailuk attended the opening
As is customary with the IWGS, the Symposium was composed of excursions to botanical gardens, visits to aquatic plant
growers, behind the scenes looks at places of interest, and a full day of educational presentations. It goes without saying that
everything took on a completely different flavor since Thailand is known for its hospitality and most attendees had never
been there before. We got to experience several non-customary events, beginning with a "Welcome IWGS" banner carried
in by elephants.
We visited both Chiang Mai and Bangkok, where we learned how Thais include aquatic plants into their daily life. Every-
where we went and whatever we did, water plants were visible. It seemed that all aspects of the Thai society (food, agricul-
ture, commerce, decoration, clothing, and religion) included at least an aquatic plant or two. Even the median strips in hectic
Bangkok were planted with several varieties of cannas and occasional pots of water lilies.
One memorable activity was a visit to Bangkok's weekly plant market. It was astounding to see the number and variety of
aquatics amid the countless other plants offered in the small crowded stalls. Since aquatic plants are so popular in Thailand,
it was possible to buy flowers, plants, fertilizer, containers, seeds, tubers, and soil. There were even small plants of the giant
Victoria amazonica for sale, many of them in flower.
Lotuses and water lilies were most common, with
some identified by name (occasionally in English)
but more often by blossom photograph. Prices were ....
Unexpected surprises were the pervasive use of .*. .
containers instead of ponds and the great popularity
of water garden displays. It seemed that almost every
home, business (large and small), and temple (gran-
diose and informal) had at least one water feature.
There would be a beautifully decorated pot filled
with water lilies.., or a small fountain with a little
moving water... or a sculptured container filled with ..
large dramatic lotuses. This was the case in busy .
Bangkok as well as laid back Chiang Mai.
It seemed that lotuses were everywhere as
plants, food, temple offerings, symbolic art, and
decoration on items in everyday life. Throughout the
Symposium we learned a great deal about numer-
ous aquatic plants, predominantly tropicals. How-
ever, since the lotus is such a revered and practical
plant, many of the educational seminars and poster
sessions dealt with it. Some of the many Nelumbo
topics included: an ethnobotanical study in Thailand,
development in China, use as a multipurpose crop in
the US southeast, and effects of gamma radiation on
growth. Photo by Paula Biles
