Assessing Non-Native Plants in Florida's Natural Areas
What does one do when the ornamental horticulture department of a university is
researching and promoting the use of a non-native plant to commercial growers and
landscapers, while other departments of the same university are researching and
advocating the control and eradication of the very same species? In the non-academic
arena, commercial growers and landscapers are outraged over the perceived threat to their
livelihood, while land managers and environmentalists are adamant about protecting their
remaining natural areas from invasive plant species. To help solve this problem, members
of the University of Florida's Institute of Food and Agricultural Sciences (IFAS) Invasive
Plants Working Group came up with an assessment protocol for non-native plants in
Florida. The protocol is an attempt to reconcile these different factions, to make sure that
labels of invasiveness can be defended to the satisfaction of everyone concerned, and to
allow those who hold a stake in the issue to be involved in a reasonable approach to its
resolution. KB
The remainder of this article was adapted from one published in the Fall 2000 issue of
Wildland Weeds, a quarterly publication of the Florida Exotic Pest Plant Council, and
University of Florida Cooperative Extension Service publication SS-AGR-79, by A.M.
Fox, D.R. Gordon, J.A. Dusky, L. Tyson, and R.K Stocker. For further information,
contact Dr. Alison Fox, E-mail: amfox(@,nv. ifas. ufl. edu
The IFAS Assessment of Non-Native Plants in Florida's Natural Areas (hereafter
referred to as the IFAS Assessment) was developed in 1999 by a subcommittee of the
IFAS Invasive Plants Working Group (A.M. Fox, J.A. Dusky, and R.K. Stocker of the
University of Florida; D.R. Gordon of The Nature Conservancy; and L. Tyson of Santa Fe
Community College).
Wilcove et al. (1998) reported that invasive species are second only to habitat loss in the U.
S. as the leading threat to threatened and endangered species. U.S. federal government
recognition of these issues was emphasized by President Clinton's Executive Order on
Invasive Species (1999). However, it is important to acknowledge that only a small
percentage of introduced species create a problem in natural areas (Lippincott 1996), and
that quantifiable ecological and economic impacts caused by invasive plants range from
negligible to catastrophic.
Around the world there is a concerted effort to develop predictive models, primarily for
species not yet present in a particular area. Many of them appear to be efficient at
identifying potential problem species, especially based on information such as whether a
species has been a problem elsewhere. A concern about many of these models has been
that they are often overly restrictive, in some cases falsely accusing up to 20% of plants
that have never (at least in the studied timescales) been found to be invasive (Reichard and
Hamilton 1997). Managers of natural areas may not consider this to be much of a flaw, but
this is unacceptable to the many people who believe that supplies of plants for food, fiber,
and landscaping should not be unnecessarily restricted.
The invasive "no-brainers" are typically well-established and little-disputed species, many
of which are already subject to state and/or federal regulation. On the other hand, it is
recognized that there are many exotic crops, for example, that do not survive without
human intervention in the form of fertilizers, irrigation, etc. Controversy, however, haunts
the middle ground and usually surrounds those commercially important species that are
either just starting to escape or that appear in natural areas but with unknown or poorly
documented impacts.
Since 1984, the Florida Exotic Pest Plant Council (FLEPPC) has been classifying
certain plants as Category I: "species that are invading and disrupting native plant
communities in Florida" based "...on the documented ecological damage caused"; or as
Category II: "species that have shown a potential to disrupt native plant communities".
The lists serve a variety of purposes (see "Florida's most invasive plant list" at http://www.
fleppc.org/) with the precautionary objective to alert managers of natural areas to
currently, or potentially, problematic species.
Things become more controversial when these lists are adopted for other purposes, such as
the development of local laws banning the use of certain non-native plants. With a large
gap between the FLEPPC lists and state and federal regulations (on the 1999 lists, only 25
out of 65 Category I species, and 3 out of 60 Category II species, are government-
regulated), it is not surprising that proactive local organizations have embraced the
Category I list.
Such regulations have alarmed ornamental horticulturists and landscape designers, who
question why some commercially important species such as heavenly bamboo (Nandina
domestica, and lantana (Lantana camera) are on the Category I list. Their concerns are
magnified because, while distribution maps are available on the FLEPPC website,
systematic, written criteria and documentary evidence on which the FLEPPC lists are
based are not available.
Purpose and Objectives of the IFAS Assessment
The primary purpose of the IFAS Assessment is to provide a mechanism to be used within
the University of Florida to develop consistent descriptions of, and recommendations for,
the use and management of non-native plants in Florida. Secondary objectives are to
provide a level of information that is intermediate between simple presence or absence on
a list and all the data that are available on any given species; and to identify the frequent
data-gaps in our knowledge of these species which would assist in setting research
priorities. It is also hoped that the IFAS Assessment will provide a tool to help resolve
some of the conflicts between FLEPPC and the Florida Nurserymen and Growers
Association (FNGA).
The requirements for the IFAS Assessment were that it have precisely defined criteria that
are defendable by faculty, all evidence and decisions should be documented and archived
for anyone to review, and it should only be used on species already present in the state.
Far less is published about most invasive species than desired for an assessment, and
anecdotal information can be difficult to defend without further substantiation. Thus, we
have defined documentary evidence as being either published and quantitative, or as
written observations from three biologists, any of whom could be contacted for
confirmation. This process would not be a sufficient replacement for formal (and much
more costly and complex) risk-benefit analysis, such as is performed in the development
of state regulations prohibiting the use of a species.
The IFAS Assessment has five major sections: one to define if a species is invasive in
Florida; and one for each of four indices ecological impacts; potential for expansion;
difficulty of management; and commercial value; closing with the conclusions. The
assessment is intentionally broader than just determining whether a species is invasive (e.
g., the latter two indices provide important information that does not address that issue),
and there is no intention to offset commercial value against ecological impacts.
Invasiveness is very broadly defined in Section I as the establishment of self-sustaining
plant populations that are expanding within a natural plant community with which they
had not previously been associated (Vitousek et al. 1995). To be declared as being
invasive, a plant must be documented in natural areas where there has not been significant
human disturbance, or it must have survived restoration of the natural communities. The
ecological impacts are evaluated in Section II based on the worst known site(s), without or
before any control effort. Scores are assigned to six items in this section that address
disruption of ecosystem processes, impacts on threatened or endangered species,
competitive displacement, changes in community structure, and hybridization with native
species. This impact score is increased if the species can invade a broad range of habitats.
In areas that a plant has invaded, an assessment of high or low potential for further
expansion (one of very few "predictive" questions) is based, in Section III, on the number
of new sites reported to be infested in the last five years. Difficulty of management and
commercial value are assessed, and result in scores based on 10 and 4 items, in Sections
IV and V respectively. A species is considered more difficult to manage if non-target
damage is hard to avoid, if access and methods of control are costly, if there are large or
dispersed areas to be managed, or if the likelihood of regrowth and re-colonization is high.
Commercial value turned out to be the most challenging index because there is no tracking
of state-wide sales receipts by species. Nobody, including representatives from FNGA,
was very satisfied with the rather vague items in this section related to retail sales and
importance to nursery growers or farmers. Thus, an analysis of the economic impact of
potentially invasive plants in the ornamental nursery industry has been proposed as an
important area for future research.
Conclusions
For all indices other than ecological impacts, the scores for a species are assigned to a high
or low category. Scores for ecological impacts, the index which drives the development of
conclusions, are assigned to low, medium, high, or very high categories. Based on the
permutations of these categories for each index, one of the following conclusions is
designated for a species:
Not considered a problem invasive species at this time (low impacts and potential for
expansion)
Caution, prevent escape of this plant (low impacts but high potential for expansion)
Avoid use of this plant (medium to high impacts)
Do not use this plant (high to very high impacts)
While this language has no regulatory authority and is obviously superseded by any state
or federal prohibitions, it is intended to provide consistent guidance.
All species will be reassessed as new information becomes available (especially in relation
to new sites or impacts) and at least every 10 years. Plants with "Caution" or "Avoid"
conclusions are to be reassessed every two years. Additionally, some of the plants
assigned to "Avoid" will be recommended for a formal risk-benefit analysis. Typically
these plants will have medium to high ecological impacts and high commercial value, and
the risk-benefit analysis should be conducted promptly. Species that are rated with very
high impacts, that score highly on all indices, or that have a combination of medium to
high impacts, high potential and low value, will not be recommended for use.
In developing the IFAS Assessment, over 20 species were tested without the formal
collection of documentary evidence. This range of species represented all categories for
each index and all conclusions. In their formal assessment, it takes a substantial effort to
collect and document the appropriate data for each species and we have several part-time
staff dedicated to this task.
As results are compiled, they will be made available online. As a large number of species
are assessed, we will test the structure and questions in the IFAS Assessment. We expect
that the assessment will continuously evolve both from these internal evaluations and from
external input, hence the long-term objective of having an interactive web-based version
rather than just the printable format currently available.
There is no doubt that for many species on the FLEPPC Category I list, similar
conclusions will be reached via the IFAS Assessment. For other species there will seem to
be a reduced level of concern based on our stringent criteria and requirements for
documented evidence. This may seem alarming to managers of natural areas, but we
anticipate that this could provide the impetus to gather more evidence, especially for
species with expanding ranges, so that problem species are quickly reassessed and
recognized. The precautionary approach of the FLEPPC lists is important for the managers
of natural areas and should be continued. The IFAS Assessment is intended to
complement this system and it is hoped that many people will contribute information on
their least-favorite plants.

New Florida Web Projects
The Florida Environments Online (FEOL) project has merged eight research
bibliographies on Florida's biotic communities into one searchable database. The
bibliographies were compiled by scientists and state agencies throughout Florida
and cover the following subjects: ornithology; fish; herpetology; geology; literature
useful to the study of Florida plants; fresh water; ecosystems; and agricultural
history. The total number of records will eventually number more than 13,000.
Although some records have yet to be entered, the system is currently available
online through WebLUIS (the Library User Information Service of the State
University System of Florida). Access can be gained through the library websites of
any of Florida's state universities.
The FEOL database is part of a larger project, Linking Florida's Natural Heritage
(LFNH), that allows students, researchers, and the public to query museum
specimen databases, library catalogs, and other citation databases for taxonomic and
topical information. Collections included in the project are Everglades Online,
Florida Environments Online, the FORMIS Ant Bibliography (29,000 references),
the Sea Turtle Bibliography (12,000 references), the State University System of
Florida library catalogs (more than ten million references (on all subjects)), the
Florida Museum of Natural History's ichthyology and herpetology specimen
collections (143,000 cataloged lots and 149,000 specimens, respectively), the Tall
Timbers Research Station bird specimen collection (3,900 specimens), and a core
collection of several hundred key publications selected for digitization. The LFNH

AQUATICS still thriving after all these years
With the recent surge in interest in exotic and invasive species of the terrestrial sort,
many researchers and managers have headed upland from their lakes, rivers and
wetlands. Let it be known that the Aquatic Plant Management Society and its
regional chapters are still alive and thriving with plenty of aquatic plants to take care
of.
The Aquatic Plant Management Society, Inc. (APMS) is an international
organization of scientists, educators, students, commercial pesticide applicators,
administrators, and concerned individuals interested in the management and study of
aquatic plants. The membership reflects a diversity of federal, state, and local
agencies; universities and colleges around the world; corporations; and small
businesses.
Originally known as the Hyacinth Control Society, Inc. when founded in 1961, the
APMS is a respected source of expertise in the field of biological, mechanical, and
chemical aquatic plant management and aquatic plant science. The Society has
grown to include chapters in Florida, Texas, South Carolina, the Midsouth,
Midwest, Northeast, Western, and the Nile Basin. Through these affiliates, annual
meetings, newsletters, and the Journal of Aquatic Plant Management, members
keep abreast of the latest developments in the field.
The objectives of the Society are to assist in promoting the management of nuisance
aquatic plants, to provide for the scientific advancement of members of the society,
to encourage scientific research, to promote university scholarship, and to extend
and develop public interest in the aquatic plant science discipline. For more

Aquaphyte Winter 2000 AQUAPHYTE ONLINE Winter 2000 Assessing Non-Native Plants in Florida's Natural Areas What does one do when the ornamental horticulture department of a university is researching and promoting the use of a non-native plant to commercial growers and landscapers, while other departments of the same university are researching and advocating the control and eradication of the very same species? In the non-academic arena, commercial growers and landscapers are outraged over the perceived threat to their livelihood, while land managers and environmentalists are adamant about protecting their remaining natural areas from invasive plant species. To help solve this problem, members of the University of Floridas Institute of Food and Agricultural Sciences (IFAS) Invasive Plants Working Group came up with an assessment protocol for non-native plants in Florida. The protocol is an attempt to reconcile these different factions, to make sure that labels of invasiveness can be defended to the satisfaction of everyone concerned, and to allow those who hold a stake in the issue to be involved in a reasonable approach to its resolution. KB The remainder of this article was adapted from one published in the Fall 2000 issue of Wildland Weeds, a quarterly publication of the Florida Exotic Pest Plant Council, and University of Florida Cooperative Extension Service publication SS-AGR-79, by A.M. Fox, D.R. Gordon, J.A. Dusky, L. Tyson, and R.K. Stocker. For further information, contact Dr. Alison Fox, E-mail: amfox@gnv.ifas.ufl.edu The IFAS Assessment of Non-Native Plants in Floridas Natural Areas (hereafter referred to as the IFAS Assessment) was developed in 1999 by a subcommittee of the IFAS Invasive Plants Working Group (A.M. Fox, J.A. Dusky, and R.K. Stocker of the University of Florida; D.R. Gordon of The Nature Conservancy; and L. Tyson of Santa Fe Community College). Wilcove et al. (1998) reported that invasive species are second only to habitat loss in the U. S. as the leading threat to threatened and endangered species. U.S. federal government recognition of these issues was emphasized by President Clintons Executive Order on Invasive Species (1999). However, it is important to acknowledge that only a small percentage of introduced species create a problem in natural areas (Lippincott 1996), and http://plants.ifas.ufl.edu/aq-w00-5.html (1 of 6) [6/6/2008 2:00:09 PM]

Aquaphyte Winter 2000 that quantifiable ecological and economic impacts caused by invasive plants range from negligible to catastrophic. Around the world there is a concerted effort to develop predictive models, primarily for species not yet present in a particular area. Many of them appear to be efficient at identifying potential problem species, especially based on information such as whether a species has been a problem elsewhere. A concern about many of these models has been that they are often overly restrictive, in some cases falsely accusing up to 20% of plants that have never (at least in the studied timescales) been found to be invasive (Reichard and Hamilton 1997). Managers of natural areas may not consider this to be much of a flaw, but this is unacceptable to the many people who believe that supplies of plants for food, fiber, and landscaping should not be unnecessarily restricted. The invasive no-brainers are typically well-established and little-disputed species, many of which are already subject to state and/or federal regulation. On the other hand, it is recognized that there are many exotic crops, for example, that do not survive without human intervention in the form of fertilizers, irrigation, etc. Controversy, however, haunts the middle ground and usually surrounds those commercially important species that are either just starting to escape or that appear in natural areas but with unknown or poorly documented impacts. Since 1984, the Florida Exotic Pest Plant Council (FLEPPC) has been classifying certain plants as Category I: species that are invading and disrupting native plant communities in Florida based ...on the documented ecological damage caused; or as Category II: species that have shown a potential to disrupt native plant communities. The lists serve a variety of purposes (see Floridas most invasive plant list at http://www. fleppc.org/) with the precautionary objective to alert managers of natural areas to currently, or potentially, problematic species. Things become more controversial when these lists are adopted for other purposes, such as the development of local laws banning the use of certain non-native plants. With a large gap between the FLEPPC lists and state and federal regulations (on the 1999 lists, only 25 out of 65 Category I species, and 3 out of 60 Category II species, are governmentregulated), it is not surprising that proactive local organizations have embraced the Category I list. Such regulations have alarmed ornamental horticulturists and landscape designers, who http://plants.ifas.ufl.edu/aq-w00-5.html (2 of 6) [6/6/2008 2:00:09 PM]
PAGE 6
Aquaphyte Winter 2000 question why some commercially important species such as heavenly bamboo (Nandina domestica), and lantana (Lantana camara) are on the Category I list. Their concerns are magnified because, while distribution maps are available on the FLEPPC website, systematic, written criteria and documentary evidence on which the FLEPPC lists are based are not available. Purpose and Objectives of the IFAS Assessment The primary purpose of the IFAS Assessment is to provide a mechanism to be used within the University of Florida to develop consistent descriptions of, and recommendations for, the use and management of non-native plants in Florida. Secondary objectives are to provide a level of information that is intermediate between simple presence or absence on a list and all the data that are available on any given species; and to identify the frequent data-gaps in our knowledge of these species which would assist in setting research priorities. It is also hoped that the IFAS Assessment will provide a tool to help resolve some of the conflicts between FLEPPC and the Florida Nurserymen and Growers Association (FNGA). The requirements for the IFAS Assessment were that it have precisely defined criteria that are defendable by faculty, all evidence and decisions should be documented and archived for anyone to review, and it should only be used on species already present in the state. Far less is published about most invasive species than desired for an assessment, and anecdotal information can be difficult to defend without further substantiation. Thus, we have defined documentary evidence as being either published and quantitative, or as written observations from three biologists, any of whom could be contacted for confirmation. This process would not be a sufficient replacement for formal (and much more costly and complex) risk-benefit analysis, such as is performed in the development of state regulations prohibiting the use of a species. The IFAS Assessment has five major sections: one to define if a species is invasive in Florida; and one for each of four indices ecological impacts; potential for expansion; difficulty of management; and commercial value; closing with the conclusions. The assessment is intentionally broader than just determining whether a species is invasive (e. g., the latter two indices provide important information that does not address that issue), and there is no intention to offset commercial value against ecological impacts. Invasiveness is very broadly defined in Section I as the establishment of self-sustaining http://plants.ifas.ufl.edu/aq-w00-5.html (3 of 6) [6/6/2008 2:00:09 PM]
PAGE 7
Aquaphyte Winter 2000 plant populations that are expanding within a natural plant community with which they had not previously been associated (Vitousek et al. 1995). To be declared as being invasive, a plant must be documented in natural areas where there has not been significant human disturbance, or it must have survived restoration of the natural communities. The ecological impacts are evaluated in Section II based on the worst known site(s), without or before any control effort. Scores are assigned to six items in this section that address disruption of ecosystem processes, impacts on threatened or endangered species, competitive displacement, changes in community structure, and hybridization with native species. This impact score is increased if the species can invade a broad range of habitats. In areas that a plant has invaded, an assessment of high or low potential for further expansion (one of very few predictive questions) is based, in Section III, on the number of new sites reported to be infested in the last five years. Difficulty of management and commercial value are assessed, and result in scores based on 10 and 4 items, in Sections IV and V respectively. A species is considered more difficult to manage if non-target damage is hard to avoid, if access and methods of control are costly, if there are large or dispersed areas to be managed, or if the likelihood of regrowth and re-colonization is high. Commercial value turned out to be the most challenging index because there is no tracking of state-wide sales receipts by species. Nobody, including representatives from FNGA, was very satisfied with the rather vague items in this section related to retail sales and importance to nursery growers or farmers. Thus, an analysis of the economic impact of potentially invasive plants in the ornamental nursery industry has been proposed as an important area for future research. Conclusions For all indices other than ecological impacts, the scores for a species are assigned to a high or low category. Scores for ecological impacts, the index which drives the development of conclusions, are assigned to low, medium, high, or very high categories. Based on the permutations of these categories for each index, one of the following conclusions is designated for a species: Not considered a problem invasive species at this time (low impacts and potential for expansion) Caution, prevent escape of this plant (low impacts but high potential for expansion) Avoid use of this plant (medium to high impacts) Do not use this plant (high to very high impacts) http://plants.ifas.ufl.edu/aq-w00-5.html (4 of 6) [6/6/2008 2:00:09 PM]

Aquaphyte Winter 2000 While this language has no regulatory authority and is obviously superseded by any state or federal prohibitions, it is intended to provide consistent guidance. All species will be reassessed as new information becomes available (especially in relation to new sites or impacts) and at least every 10 years. Plants with Caution or Avoid conclusions are to be reassessed every two years. Additionally, some of the plants assigned to Avoid will be recommended for a formal risk-benefit analysis. Typically these plants will have medium to high ecological impacts and high commercial value, and the risk-benefit analysis should be conducted promptly. Species that are rated with very high impacts, that score highly on all indices, or that have a combination of medium to high impacts, high potential and low value, will not be recommended for use. In developing the IFAS Assessment, over 20 species were tested without the formal collection of documentary evidence. This range of species represented all categories for each index and all conclusions. In their formal assessment, it takes a substantial effort to collect and document the appropriate data for each species and we have several part-time staff dedicated to this task. As results are compiled, they will be made available online. As a large number of species are assessed, we will test the structure and questions in the IFAS Assessment. We expect that the assessment will continuously evolve both from these internal evaluations and from external input, hence the long-term objective of having an interactive web-based version rather than just the printable format currently available. There is no doubt that for many species on the FLEPPC Category I list, similar conclusions will be reached via the IFAS Assessment. For other species there will seem to be a reduced level of concern based on our stringent criteria and requirements for documented evidence. This may seem alarming to managers of natural areas, but we anticipate that this could provide the impetus to gather more evidence, especially for species with expanding ranges, so that problem species are quickly reassessed and recognized. The precautionary approach of the FLEPPC lists is important for the managers of natural areas and should be continued. The IFAS Assessment is intended to complement this system and it is hoped that many people will contribute information on their least-favorite plants.

20(2) New Florida Web Projects AQUAPHYTE ONLINE Winter 2000 New Florida Web Projects The Florida Environments Online (FEOL) project has merged eight research bibliographies on Floridas biotic communities into one searchable database. The bibliographies were compiled by scientists and state agencies throughout Florida and cover the following subjects: ornithology; fish; herpetology; geology; literature useful to the study of Florida plants; fresh water; ecosystems; and agricultural history. The total number of records will eventually number more than 13,000. Although some records have yet to be entered, the system is currently available online through WebLUIS (the Library User Information Service of the State University System of Florida). Access can be gained through the library websites of any of Floridas state universities. The FEOL database is part of a larger project, Linking Floridas Natural Heritage (LFNH), that allows students, researchers, and the public to query museum specimen databases, library catalogs, and other citation databases for taxonomic and topical information. Collections included in the project are Everglades Online, Florida Environments Online, the FORMIS Ant Bibliography (29,000 references), the Sea Turtle Bibliography (12,000 references), the State University System of Florida library catalogs (more than ten million references (on all subjects)), the Florida Museum of Natural Historys ichthyology and herpetology specimen collections (143,000 cataloged lots and 149,000 specimens, respectively), the Tall Timbers Research Station bird specimen collection (3,900 specimens), and a core collection of several hundred key publications selected for digitization.

20(2) AQUATICS AQUAPHYTE ONLINE Winter 2000 AQUATICS still thriving after all these years With the recent surge in interest in exotic and invasive species of the terrestrial sort, many researchers and managers have headed upland from their lakes, rivers and wetlands. Let it be known that the Aquatic Plant Management Society and its regional chapters are still alive and thriving with plenty of aquatic plants to take care of. The Aquatic Plant Management Society, Inc. (APMS) is an international organization of scientists, educators, students, commercial pesticide applicators, administrators, and concerned individuals interested in the management and study of aquatic plants. The membership reflects a diversity of federal, state, and local agencies; universities and colleges around the world; corporations; and small businesses. Originally known as the Hyacinth Control Society, Inc. when founded in 1961, the APMS is a respected source of expertise in the field of biological, mechanical, and chemical aquatic plant management and aquatic plant science. The Society has grown to include chapters in Florida, Texas, South Carolina, the Midsouth, Midwest, Northeast, Western, and the Nile Basin. Through these affiliates, annual meetings, newsletters, and the Journal of Aquatic Plant Management, members keep abreast of the latest developments in the field. The objectives of the Society are to assist in promoting the management of nuisance aquatic plants, to provide for the scientific advancement of members of the society, to encourage scientific research, to promote university scholarship, and to extend and develop public interest in the aquatic plant science discipline.

Volume 20 Number 2 Winter 2000 AQUAPHYTE ONLINE Winter 2000 Odds n' Ends Harmful Nonnative Weed Control Act of 2000. U.S. Senate Bill S. 3222, introduced by Sen. Larry Craig (with 7 co-sponsors so far), seeks to raise federal money and to require the Secretary of the Interior to provide assistance [through the States] to eligible weed management entities to control or eradicate harmful, nonnative weeds on public and private lands. The bill was referred to the Committee on Energy and Natural Resources; it is expected to be reintroduced to the new Congress in 2001, with possible hearings in the winter. Individuals can read and track the bill through: http://thomas.loc.gov/home/c106query.html or contact Myra Hyde, mhyde@beef.org The World Biodiversity Database (WBD) is now 10 years old. A project of ETI (Expert Center for Taxonomic Identification), the WBD now has information on about 120,000 species. The ETI Biodiversity Center, supported by UNESCO, the Dutch government and the University of Amsterdam, seeks nothing less than to make it possible to use the Internet to identify plants and animals from all over the world. Visit their web site: http://www.eti.uva.nl Vascular Plant Type Catalog. The New York Botanical Garden is working to become the first major herbarium to place online information about and photographs of its (90,000) vascular plant type specimens. The web site is clean and easy to use; the hi-resolution pictures are very well done: http://www.nybg.org/bsci/hcol/vasc/ Biological Invasions Journal. This very interesting new scientific journal, as described in the last issue of AQUAPHYTE, has to do with plant and animal invaders. The first several issues of Biological Invasions are now online, and downloadable as PDF files by licensed institutions, including Volume 1, Issue 2/3, which has several articles about invading aquatic plants, such as an excellent article by D.H. Les and L.J. Mehrhoff on the methods of introduction, avenues and means of dispersal, and extent of invasiveness of 18 aquatic plants in southern New England: http://www.wkap.nl.jrnltoc.htm/1387-3547 http://plants.ifas.ufl.edu/aq-w00-2.html (1 of 3) [6/6/2008 2:00:13 PM]
