The CAIP Information Office

By Karen Brown, Information Office Coordinator

The CAIP Information Office serves as the outreach arm of the University of Florida/Institute
of Food and Agricultural Sciences Center for Aquatic & Invasive Plants (CAIP). With the evolution
of Internet technology, our efforts have changed a lot in the thirty plus years we’ve been serving the
Center and its stakeholders. It’s amazing to look back and see where we started and where we are
today. The format of everything we’ve done has changed many times, but that really only interests
us veterans. In with the new is what we try to do and we are fortunate to have a diverse group in our
Information Office that keeps us up to date.

The CAIP website continues to be our primary outreach tool. While many users simply have
our home page bookmarked, other users find us through a “back door” when they search the Inter¬
net for information about an invasive species and are directed to one of our Plant Information & Im¬
ages pages. Others _

are looking for line
drawings or species
identification videos.

Some are search¬
ing for management
options, weed alerts
and other publica¬
tions, or announce¬
ments of profession¬
al meetings. Our ex¬
tensive website has
all of these tools and
we are continually
updating it with new

information and materials. Our home page features upcoming events, recent publications, ongoing
cooperative projects and more. Our site navigation bar features Plant Information & Images which
opens to a drop down menu (see image).

The scientific and common name pages open to an alphabetized list that also indicates
whether a plant species is native or non-native. Clicking on a plant name provides an encyclopedic
trove of information and images for that species, although content varies widely based on
the importance of the species in Florida’s public waters and lands. The most comprehensive
pages include plant origin, date and method of introduction to Florida, an identification video,
toxicity to livestock (where relevant), legal prohibitions (both federal and state), the category of
invasiveness according to the Florida Exotic Pest Plant Council (FLEPPC) Plant Eist Committee

(composed of twelve botanists from around the state), a
link to the UF/IFAS Assessment of Non-Native Plants in
Florida’s Natural Areas, a link to the relevant recognition
card from our plant identification deck. Invasive and
Non-Native Plants You Should Know, a link to a page
from the book. Identification and Biology of Non-Native
Plants in Florida’s Natural Areas - Second Edition

The CAIP website receives a
tremendous number of visits.
During the past 12 months,
it had almost half a million
visitors and almost one-and-a-
half million page views.

available control publications (usually written by UF extension
faculty), and any available full-scale management plans (usually
written by UF faculty but sometimes by task forces from FLEPPC
or other professional managers). Any additional links or resources
are provided, as well. Users who simply want to view a weed alert
or plant ID video or line drawing can choose those options from
the drop down menu under Plant Info & Images.

The APIRS Database continues to be a freely available,
heavily used collection of annotated bibliographic records. During
the past 12 months, the database had almost 2,000 users and over
8,000 page views. For a sampling of citations, see From the
Database on page 10. Longtime science reader Mary Langeland
and program assistant Anne Taylor add new records, re-catalog
important old records, add information on finding publications,
and work on fine-tuning the database holdings on a continual basis.
The database is currently approaching 89,000 records and can be
searched using the Search All Fields function or by individual
fields. Basic search examples are provided on the main search
page, and Advanced Search Strategies are provided via a link at
the top and bottom of the main search page. Literature searches
also can be requested by contacting Karen Brown.

Site visitors can also read or download prior issues of
AQUAPHYTE, use our Plant Glossary, check out Invasive
Plant Laws (state and federal), view the publications and products
we offer for sale (to cover the cost of reprinting), and see free
publications that can be downloaded and printed.

Going back to the home page, viewers should see three images
on the right side. The first image links to Plant Management in
Florida Waters. This website explains why and how aquatic
plants are managed in Florida waters and guides users through
the many factors considered by state biologists when developing
aquatic plant management plans for Florida public waters. Ninety-
six percent of Florida’s 466 public waters inventoried in 2012-
2013 contained one or more exotic plants. According to the Florida
Fish & Wildlife Conservation Commission (FWC), the agency
charged with managing these plants, the top 12 invasive aquatic
plants are aquatic soda apple {Solarium tampicense), giant salvinia
(Salvinia molesta), hydrilla {Hydrilla verticillata), hygrophila
(Hygrophila polysperma), napier grass (Pennisetum purpureum),
para grass (Urochloa mutica), torpedograss {Panicum repens),
water hyacinth {Eichhornia crassipes), water lettuce (Pistia
stratiotes), water spinach (Ipomoea aquatica). West Indian marsh
grass {Hymenachne amplexicaulis), and wild taro (Colocasia
esculenta). These plants are ranked using the Annual Report of
the Status of the Aquatic Plant Maintenance Program in Florida
Public Waters by FWC. In 2013, hydrilla was found in 187
public water bodies and it covered 28,610 acres. Many of these
plants are under maintenance control but still have the potential
to become serious problems without vigilant oversight. These
top 12 invaders are profiled in Section 1 “Why Manage Plants?”
of the Plant Management site. While the information provided
is similar to that provided on the CAIP primary website pages,
the Plant Management in Florida Waters website was created to
work as a stand-alone site. Section 1 also includes information
about native and non-native plants, aquatic and wetland plants in
Florida, a photo history of Florida steamboats and water hyacinth
management, scenic postcards depicting scenes of Florida waters
from the turn of the last century through the mid-1900s.

Section 2, Overview of Florida Waters, presents information
on waterbody types, water quality, shared uses and functions and
the potential for conflicts, and fish and wildlife.

Section 3, Control Methods, provides an in-depth look at
the various control methods used in aquatic plant management.
Illustrations and video clips show biological control agents,
mechanical control equipment, and some aspects of chemical
control.

Section 4, Developing Management Plans, is the most
content-intensive section. It shows how information from other
sections of the website is incorporated into comprehensive
management strategies for water bodies in which FWC issues
permits or enters into contracts to provide aquatic plant
control. Integrated pest management (IPM) is presented in
terms of interactions among water uses, plant types, available
technologies, current environmental conditions, and funding.

Section 5, Research and Outreach, provides just that, with
categories for citizens, educators, and plant managers. There are
also frequently asked questions and a video gallery.

The Plant Management in Florida Waters website was
revised and relaunched two years ago and garnered 48,000 visits
and over 100,000 page views during the past year, a 27% increase
from a year ago.

The second image links to the Florida Invasive Plant
Education Initiative & Curriculum. This program is aimed at
educators and their students and is coordinated by Katie Walters
with the assistance of Lynda Dillon and Gary Kreitzer, and with
Charlie Bogatescu handling the web site and providing graphic
design assistance. See Katie’s article on page 4.

Finally, the third image links to the IFAS Assessment of
Non-Native Plants in Florida’s Natural Areas. This website
uses “literature-based assessment tools to evaluate the invasion
risk of non-native species that occur in the state, new species
proposed for introduction, and novel agricultural and horticultural
selections.” Their “overarching goal is to reduce non-native
plant invasions in Florida and throughout the Southeast US for
protection of natural and agricultural areas.” This project was
begun when it became apparent that some of the plant species
being promoted for landscape use by the university’s horticulture
department becoming invasive in Florida natural areas. A
science-based assessment was created to demonstrate different
levels of invasiveness in different regions of the state before a
species could be referred to by faculty members as invasive. The
Assessment has since grown into a highly used and trusted tool.
Recently, the website was completed overhauled and redesigned
to be much easier to use. Be sure to visit and view the 800+
species, easily searchable by common or scientific name, with
results that can be filtered by origin, conclusion, growth form,
and more. Over 1500 pictures (all open source or credited) were
compiled and species information includes growth form, origin,
and links to other websites. The database is directly linked to the
web site so any time a species is added or updated in the database,
the species web pages are automatically built or updated and
available for public viewing.

Please tour our suite of websites and send us your feedback.

At the Center 2014-2015

By Dr. William T. Haller, Acting Director

A major event here at the UF/IFAS Center for Aquatic &
Invasive Plants (CAIP) in 2014 was the retirement of Dr. Ken
Langeland, followed by seeking administrative approval to hire a
new faculty member to continue his important extension/research
programs in invasive plant management.

Dr. Langeland retired in May 2014 following 28 years of
research and the development of pioneering extension programs
in both aquatic and natural area weed biology and management.
A search of the APIRS database by author name = Langeland
reveals nearly 500 citations which is indicative of a highly
productive career. In addition, many of his publications on the UF/
IFAS Extension website (EDIS) were among the highest 10% of
documents downloaded or viewed on the entire website.

Ken was also a “Charter” member of the university’s internal
IFAS Invasive Plant Working Group formed by the IFAS Deans
for Research and Extension to standardize faculty and staff
recommendations on use and planting of potential invasive plants
in Florida. The invasive potential of plants was to be assessed
based upon scientific data where possible and gave rise to the
development of the UF/IFAS Assessment of Non-Native Plants
in Florida’s Natural Areas (http://assessment.ifas.ufl.edu/). Over
time several faculty and staff members have made significant
contributions. The Assessment is currently being directed by Drs.
Euke Flory and Deah Eieurance and can be accessed directly
from our website as described on page one of this newsletter. The
Assessment website is updated continuously and has very recently
been upgraded to make it much more user friendly.

The first half of Ken’s career at UF was primarily involved
in working with aquatic weeds, after which he undertook the
challenge of developing information on natural area weeds,
particularly, but not limited to, research on Old World climbing
fern (Lygodium microphyllum). This species, first noted in the mid-
1980s, continues to expand in Florida and is difficult to control
despite release of biocontrol agents and use of herbicides.

In March 2014 the UF/IFAS administration authorized a faculty
position with similar extension/research responsibilities to those
of Dr. Eangeland. The position has the Agronomy Department as
its academic home and we appreciate the Agronomy Faculty and
Chair for their support of filling this need in the weed science area.
Following a nationwide search and interviews of the top ranked
candidates, the position was accepted by Dr. Stephen Enloe.

Stephen has nationwide experience in the biology and control
of invasive plants having completed his undergraduate degree in
agronomy at North Carolina State, a Master’s degree at Colorado
State University and ultimately his PhD degree from the University
of California-Davis in 2002. Following receipt of his Doctorate he
has worked in both extension and research, first at the University
of Wyoming for 5 years, followed by 6 years of experience at
Auburn University where he achieved the rank of Associate
Professor. He has numerous extension and research publications
and worked with a very diverse range of invasive plants in natural
areas, forestry, range, rights-of-way, and agronomic crops. We
welcome Stephen to the Weed Science group at the UF/IFAS and
look forward to his contributions to CAIP and our stakeholders for
many years to come.

UF/IFAS has several Research and Education Centers (RECs)
across the state, from Homestead to Pensacola. This issue of
AQUAPHYTE highlights the research program of Dr. Eyn Gettys
(Agronomy Department) at the Ft. Eauderdale REC.

Dr. Stephen Marble (Environmental Horticulture Department)
began his research and extension career in Florida at the Mid-
Florida REC in Apopka, Florida in July 2014. Stephen will be
developing research and educational programs on invasive species
and weeds primarily in landscape, turf and ornamentals. We look
forward to covering Stephen’s program in a future edition of
AQUAPHYTE and referring homeowners and others with weed
problems in their landscapes to him. Stephen can be contacted at
marblesc@ufl.edu.

The high quality, dedication and cooperation of the weed
science group at the UF/IFAS across several departments -
entomology, horticulture, botany, soil science, fisheries, agronomy
and others over the past 35 years - has allowed the CAIP and
IFAS to assume a leading national role in the study of invasive
plant biology and the development of management programs. The
education staff of the CAIP is expanding the highly successful
PEANT CAMP, Eakeville and other educational programs to other
states in the southeast and hopefully to northern states in the near
future. Most biologists and ecologists believe that prevention of
introductions and ultimately the need for management programs
for invasive species lies with teaching young people the dangers
and adverse impacts that invasive species have in this country.
A critical component of the success of the Florida invasive plant
management and educational programs has been the cooperation
between the Eand Grant College and the state management agencies,
primarily the Florida Fish and Wildlife Conservation Commission
(FWC), as well as the regional water management districts and
other stakeholder groups. The Invasive Plant Management Section
of the FWC has provided very significant funding for many CAIP
programs including, but not limited to, the educational effort for
secondary school teachers and students, the APIRS database,
graduate student education, the plant evaluation and assessment
project, and many research projects on the biology and ecology of
invasive species, as well as biological control efforts and studies
on the selectivity, and registration of new aquatic herbicides. The
value of the cooperation of the CAIP staff and affiliated faculty
at the UF with the FWC and other stakeholder groups cannot be
over-emphasized.

A new graduate student at the Center this year is Joshua
Woods who completed his Bachelor of Science degree in biology
at Manchester College in Indiana and is now working with Dr.
Mike Netherland on a Master of Science (MS) degree. Also this
year, Carl Della Torre departed CAIP to move to the Ft. Eauderdale
REC to complete his MS degree with Dr. Eyn Gettys. Eeif Willey
received his MS degree and is now working with Aquatic Systems,
a commercial weed and pond management firm in south Florida.

An update from the Florida Invasive Plant Education Initiative

By Katie Walters, Coordinator, Education Initiative

T he Florida Invasive Plant Edueation Initiative provides
teaehers with the training and resourees neeessary to bring
invasive speeies lessons into the elassroom. We provide four
eurrieulum modules, an annual professional development
workshop for edueators (PLANT CAMP), online resourees,
in-elass presentations, and edueational materials and games.
Regular eommunieation and eollaboration with teaehers
ensures our materials remain relevant and able to be used in
the elassroom. Our eontinuing partnership with the Florida
Fish and Wildlife Conservation Commission (FWC) and
organizations sueh as the Florida Aquatie Plant Management
Soeiety (FAPMS), the Aquatie Plant Management Soeiety
(APMS), and the Aquatie Eeosystem Restoration Foundation
(AERF), allow us to offer these materials and workshops at
no eost to Florida edueators. Over 300 teaehers have attended
our workshops who, in turn, have taught approximately
70,000 Florida students over the last 9 years!

NEW-Common Core
State Standard Activities

The Edueation Initiative partnered with a former
PLANT CAMP teaeher to develop 15 reading aetivities that
eneourage higher-order thinking. Students are introdueed
to the voeabulary of native, non-native, and invasive. They
are also introdueed to the eategories of submersed, emersed,
floating-leaved, and free-floating as ways to elassify aquatie
plants. These reading aetivities are in line with the Florida
Standards and the Common Core State Standards for Eng¬
lish Language Arts, eurrently adopted by 43 states. Eduea¬

PLANT CAMP 2014 Report

PLANT CAMP 2014 was a huge sueeess thanks to all
our sponsors, presenters and, of eourse, our teaeher partiei-
pants! Teaehers work hard all week and are sent home with
staeks of materials to use in their elassrooms. On their evalu¬
ations, all partieipants reported they either “strongly agreed”
or “agreed” that PLANT CAMP inereased their knowledge
on invasives and the important role edueation has to play
in addressing this issue. A full 100% of teaeher partieipants
planned to teaeh about aquatie invasive plants and share
what they learned with other teaehers.

This year we bid farewell to FWC’s Invasive Plant Man¬
agement Seetion Administrator Jeff Sehardt. Jeff was eentral
to the organization and implementation of PLANT CAMP
from its ineeption. He worked tirelessly to improve the
week-long workshop, getting more ageneies and presenters
involved, planning the eontent of the agenda, and develop¬
ing materials for elassroom use. He will be enjoying a well-
deserved retirement and will be missed - but thanks to all his

hard work, PLANT CAMP will eontinue on!

Eaeh year we administer a pre- and post-test of 8 knowl¬
edge-based questions to teaeher partieipants. We also ask that
they eomplete a pre- and post-survey to determine aware¬
ness and aeeeptanee of plant management methods. Pre- and
post-test results were eneouraging. Overall, the teaehers
greatly improved their seores. The highest pereent gain was
seen on a plant identifleation question where 6 teaehers an¬
swered eorreetly pre-eamp and 19 answered eorreetly post-
eamp. There was a 61% gain on the eorreet definition of a
non-native plant, showing an understanding that non-native
plants are not neeessarily invasive, and a 27% gain on the
eorreet definition of a native plant.

The survey (results next page) asked the teaehers’ opin¬
ion on methods of invasive plant management - ehemieal,
meehanieal, biologieal, and physieal. Below is a ehart show¬
ing the pre- and post-survey results on the question - “Do
you agree or disagree that the following methods are neees¬
sary for eontrolling invasive plants?” The pre-survey shows

NEW-Instructional Video on Lakeville

Lakeville is an interaetive eurrieulum unit that introdue-
es students to the real-world seenario of managing a fresh¬
water eeosystem. This role-play aetivity demonstrates the
interrelation of soeial, politieal, eeonomie, and eeologieal
eoneems. Students play the role of a stakeholder (anglers,
developers, farmers, politieians, nature lovers, ete.) or an or¬
ganism (native, non-native, and invasive plants and animals)
as part of a hypothetieal loeal freshwater eeosystem ealled
Lakeville. The aetivity ehallenges students to integrate their
new understanding of the impaets of invasive speeies with
an understanding of how natural resouree management de-
eisions are made (and, hopefully, how better deeisions ean
be made). The Lakeville Unit is made up of three sessions,
with the last session being the role-play aetivity. We have
reeently produeed an instruetional guide and video to help
teaehers implement the Lakeville Unit in their elassroom.
The video was produeed based on feedbaek from teaehers
who have used the aetivity in their elassrooms. It eovers the
logisties of set-up as well as helpful eontent hints, ineluding
questions to ask the students to spark diseussion. The video
is available online at http://plants.ifas.ufl.edu/edueation/

Spreading outside Florida

This summer, two teaehers from the Carolinas traveled
to Florida to join us at our annual PLANT CAMP workshop.
These teaehers wanted to get ideas on how to take our
Florida-based program into North and South Carolina. Until
this summer, all of our eurrieula lessons were speeifle to
Florida-both in eontent and in edueation standard alignment.
Now that several states have adopted the same (or similar)
edueation standards, it is easier to adapt our lessons to be used
in other states. With the sponsorship of the South Carolina
Chapter of the Aquatie Plant Management Soeiety and the
help of our PLANT CAMP motivated edueators, the Florida
Edueation Initiative adapted om Lakeville eurrieulum unit for
the Carolinas. Both states reeeived 5 teaeher kits eomplete
with all the materials needed to implement the lesson. All
materials are also hosted on iTunes U, an applieation that
allows teaehers and students to aeeess eourse materials with
their iPads.

Aquatic Activities at the

UF/IFAS Fort Lauderdale Research & Education Center

By Lyn A. Gettys, Assistant Professor of Agronomy

T he University of Florida’s Institute of Food and Agricultural
Sciences (UF/IFAS) has an active aquatics program in
south Florida. The Fort Lauderdale Research & Education
Center (FLREC) is situated within a tropical climate that
enables us to do aquatic plant research year-round and we are
finishing up our third full year of research. We have a number
of research projects that focus on the biology and control of
aquatic invasive species, while other projects aim to provide
guidance for nursery and restoration managers. A sampling of
these projects includes:

Vegetative reproductive biology of crested
floating heart (Nymphoides cristata)

Nymphoides cristata
Photo by Vernon Vandiver, University of Florida (2010)

The goal of these studies is to investigate how substrate
composition and fertility affect production of ramets by
crested fioating heart, one of Florida’s newest prohibited
aquatic plants (see image on back page). We are also
studying the infiuence of desiccation and burial depth
on ramet sprouting in this fioating-leaved aquatic weed.

Integrated pest management for control of
waterhyacinth {Eichhornia crassipes)

We are evaluating the effects of combining the herbicide
2,4-D with three biological control insects - the long-established
weevils Neochetina eichhorniae and N. bruchi and the newly
introduced leaf-hopper Megamelus scutellaris. Our first run of
this research revealed synergy between the control methods, and
we are conducting the second year of this research in cooperation
with Dr. Phil Tipping at the U.S. Department of Agriculture
Invasive Plants Research Eaboratory in Davie, Florida.

Biology and control of rotala (Rotala
rotundifolia)

Research is being conducted by Carl Della Torre III,
a master’s level graduate student at the FEREC. Carl is

investigating the effects
of substrate composition
and fertility on vegetative
reproduction of rotala, one of
south Florida’s most serious
canal weeds. He recently
completed near-comprehensive
studies to determine the
effects of foliar and submersed
aquatic herbicide applications
on this new invader and is in
the process of planning field
trials to verify the results
of these mesocosm studies.

Carl presented his research on rotala at the annual Southeast
Exotic Pest Plant Council in Athens, GA and tied for
first place in the graduate student poster competition.

Greenhouse production and mitigation potential
of native wetland plants

The first part of this project aims to provide guidance for
commercial growers of native aquatic and wetland plants so
these desirable species can be produced more efficiently. We
are evaluating the growth of native species under a range of
substrate and fertility regimes and are also comparing the
growth of these plants using bottom irrigation and overhead
irrigation. The second component of this project is focused
on nutrient uptake by native species grown in fioating islands.
The goal of these studies is to determine which species could
be useful phytoremediation agents to remove nutrients from
aquatic systems.

Upcoming projects include evaluation of ecotypes of giant
bulrush (Schoenoplectus californicus) to identify differences in
preferred growing conditions; studying the effects of propagule
size, planting density and seasonality on field establishment of
bulrush; providing plant material and guidance for restoration
of springs near Crystal River; and a number of field trials to
evaluate the effects of various aquatic herbicides alone and in
combination on rotala and crested fioating heart.

Upcoming events include the Annual UF/IFAS FEREC
Open House (Jan 24* in Davie), a full-day aquatics session at
the Florida Mosquito Control Association’s Dodd Short Course
(Jan 28* in Altamonte Springs), the Florida Weed Science
Society annual meeting (March 2"‘^ & 3* in Haines City) and the
UF/IFAS and FWC Invasive Plants Section Research Review
(March 4* & 5* in Orlando).

Retirement of Note

By William Haller and Karen Brown

Dr. George Bowes, Professor Emeritus
Biology (Botany)

University of Florida, Gainesville

Aquatic Botany is the International Scientific Journal dealing
with Applied and Fundamental Research on Submerged, Floating
and Emergent Plants in Marine and Freshwater Ecosystems,
published by Elsevier. Volume 118, August 2014 was a special
issue paying tribute to Dr. George Bowes. Bowes served on the
editorial board of Aquatic Botany from 1982 to 1995, and as
Editor-in-Chief until 2013, for a total of 31 years of service to
both contributors and readers of that highly esteemed publication.

Dr. Bowes was educated in England and received his PhD in
1967 from the University of Eondon. He came to the University of
Florida in 1972 and spent the rest of his career here in the Botany
Department. In his photosynthesis research laboratory, he studied
the ecophysiology of aquatic plants, including the management
of weed species. In particular, he studied the submersed aquatic
weed, Hydrilla verticillata and the molecular details of the
Hydrilla system. Over the years, work by Dr. Bowes and his
co-workers established Hydrilla as a C^-NADP-ME plant and
“it is now one of the most completely studied plants on the
planef’ (Reiskind and Maberly, 2014). He also worked on marine
macroalgae and terrestrial agronomic species during his career,
thus contributing excellent science to the terrestrial, freshwater
and marine disciplines. Dr. Bowes taught graduate courses in
photophysiology of plant growth and ecology, and physiology of
aquatic plants, as well as undergraduate courses. He was Chair of
the Botany Department from 1998 to 2006.

Dr. Bowes remains active in marine research and, with
colleagues from around Florida, recently published a review on
the impact of global climate change on ocean acidification and its

Bill, I am very appreciative for all your help over the years.
To be honest I'm not sure what track my research would have
taken if you had not got me interested in aquatic "weeds."

Best wishes...George

Limited copies are available as a 5 I/ 2 ” x 8 14” hard copy, the pages
of which appear to be waterproof The 196-page field guide by
Dr. Cho et al. offers excellent photographs of freshwater native
and non-native plants found in and around urban water bodies
such as stormwater retention/detention basins, drainage ditches
and associated wetlands. Plant surveys were largely done in
the Greater Daytona Beach, Florida urban area; however, some
surveys covered areas in Deland and Deltona. Within the guide
the plants are arranged by zones, from obligate wetland plants to
facultative upland and upland species. Of the approximately 150
plants in the book, each plant has a page with several photographs
for identification, as well as the taxonomy, growth form, native or
non-native status and comments with information unique to the
plant. [Excerpts adapted from the field guide.]

TION CIRCULAR III]. 2014. FLORIDA LAKEWATCH
PROGRAM, UNIVERSITY OF FLORIDA, INSTITUTE OF
FOOD AND AGRICULTURAL SCIENCES, PROGRAM IN
FISHERIES AND AQUATIC SCIENCES, GAINESVILLE,
FLORIDA. 43 PP.

“A Beginner’s Guide to Water Management - Aquatic
Plants in Florida Lakes” was first printed in October 2007 as
an Extension publication available online at EDIS (Electronic
Document Information Source) and revised in June 2014. The
abstract describes the guide as follows: This circular represents
a summary of current knowledge on aquatic plants and aquatic
plant management strategies, highlighting the Florida situation.
The major focus of this circular is the management of aquatic
plants as opposed to dealing with nutrients, algae, or water clarity.
Included are sections on 1) Aquatic Plant Biology, 2) Aquatic
Plant Management Problems, and 3) Aquatic Plant Management
Techniques. Section 1, Essentials of Aquatic Plant Biology,
describes how aquatic plants fit into the ecology of Florida lakes.
Understanding the role of aquatic macrophytes in water bodies,
especially with regard to water quality and fisheries, is critical to
the development of sound management plans. Section 2 addresses
the question of whether there is a weed problem at a lake. This
section focuses on how to define the problem and identify possible
causes for the problem. Section 3 discusses the various aquatic plant
management techniques that are currently available for managing
nuisance growth of aquatic weeds. Specific attention is given to
mechanical, chemical, and biological controls with discussion of
the pros and cons of using these techniques. Available online at

FOXCROFT, L.C., PYSEK, R, RICHARDSON, D.M.
& GENOVESI, R (EDS.) 2013. PLANT INVASIONS IN
PROTECTED AREAS: PATTERNS, PROBLEMS AND
CHALLENGES [INVADING NATURE - SPRINGER
SERIES IN INVASION ECOLOGY, VOLUME 7]. SPRINGER
SCIENCE AND BUSINESS MEDIA, NEW YORK, NEW
YORK. 661 PP.

The editors set three main aims for this book: to determine
the status of knowledge on plant invasions in protected areas and
synthesize these insights; to integrate this with current models and
theories of plant invasion ecology; and, to determine key knowledge
areas for informing the development of successful management
strategies. From the chapter entitled “Global Efforts to Address
the Wicked Problem of Invasive Alien Species” by McNeely
to one entitled “A Pragmatic Approach to the Management of
Plant Invasions in Galapagos” by Gardener et al, this collection
is a useful summary for protected area managers on important
management issues. It is hoped that “reading the chapters of
this book will lead to heightened levels of commitment by both
decision-makers and managers to combatting the invasion of our
priceless protected areas by alien species throughout the world.”
(Ian A. W. Macdonald, Extraordinary Professor, Sustainability
Institute, School of Public Leadership, Stellenbosch University,
South Africa).

Foxcroft et al. note that “The primary international forum
for deliberations on plant invasions is the conference series on
Ecology and Management of Alien Plant Invasions (EMAPI)
which started in 1992. The concept of examining alien plant
invasions in protected areas was initiated through a special session
on the topic at the 10th EMAPI conference in Stellenbosch, South
Africa, in 2009, and was followed up at the 11th EMAPI meeting in
2011 in Szombathely, Hungary. The seeds sown at these meetings
grew into this book, which we hope presents a balanced synthesis
of the current situation of invasive plants in protected areas and
stimulates new work to deal with the massive challenges that lie
ahead.” [Adapted and excerpted from the book.]

2014. HYDRILLA INTEGRATED MANAGEMENT 2014
[IPM-207]. UNIVERSITY OF FLORIDA, DEPARTMENT
OF ENTOMOLOGY AND NEMATOLOGY, GAINESVILLE,
FLORIDA. 144 PP.

According to the U.S. Environmental Protection Agency
(EPA) “throughout Florida and at least twenty-seven other states,
the invasive freshwater plant Hydrilla {Hydrilla verticillata)
causes damaging infestations that choke out native plants, clog
fiood control structures, and impede waterway navigation and
recreational use.” The focus of the book is on hydrilla management
in Florida, although the described tactics are known and used in
many of the 28 states in the United States with hydrilla infestations.
Divided into seven chapters, the book guides the reader through
a general introduction to the problems associated with hydrilla;
identification of the plant; instructions for early detection of
infestations including federal and state laws and regulations;

detailed descriptions of available control tactics; proposals for
integrated management plans; descriptions of insects and fish
associated with hydrilla; and supplementary information including
contacts for assistance when readers encounter infestations.

User groups range from lakefront homeowners to recreational
visitors to aquatic plant managers to businesses that support
ecotourism. The IPM guide for hydrilla is available as an online
resource or a printable pdf file at the University of Florida

GUIDE TO WISCONSIN STREAMS: PLANTS, FISHES,

THE UNIVERSITY OF WISCONSIN PRESS, MADISON,
WISCONSIN. 335 PP.

Wisconsin is home to 84,000 miles of streams and this field
guide is useful for learning about the animals and identifying the
plants in Wisconsin streams. A collaborative effort by dozens of
biologists and ecologists, "Field Guide to Wisconsin Streams" is
of value to anglers, teachers and students, amateur naturalists, and
experienced scientists alike.

More than 1,000 images illustrate the species in the field
guide, augmented by ecological and taxonomic notes, descriptions
of look-alike species, and distribution maps. The guide identifies
more than 130 common plants, all 120 fishes known to inhabit
Wisconsin streams, 8 crayfishes, 50 mussels, 10 amphibians,
17 reptiles, 70 families of insects, and other commonly found
invertebrates. {Excerpts adapted from the field guide.]

QUINN, L.D., ENDRES, A.B. & VOIGT, T.B. 2014. WHY NOT
HARVEST EXISTING INVADERS FOR BIOETHANOL?
BIOLOGICAL INVASIONS 16:1559-1566

The Biological Invasions article by Quinn et al. addresses the
question which is also the title - Why not harvest existing invaders
for bioethanol? This is not a new issue - how to utilize invasive
plant biomass in a useful way to benefit both the environment
and humans. Proponents suggest “...the plan could motivate the
large-scale eradication of an array of troubling invaders, avoid
land use conversion, resolve the food vs fuel debate, result in
millions of gallons of clean-burning ethanol, and finally free us
from our addiction to fossil fuels.” In response to this supposedly
win-win suggestion, the authors look in detail at the economic,
logistic, and legal barriers currently preventing adoption of such a
plan. The conclusions drawn are somewhat pessimistic given the
barriers. Quinn et al. suggest “Perhaps as the biomass-to-ethanol
industry matures over the next half century, technical innovations
may reduce the currently insurmountable logistic and economic
concerns associated with utilizing existing invasive feedstocks for
viable sources of liquid fuel.” {Excerpts adaptedfrom the article.]

Bousquin, “Phase I of the Kissimmee River Restoration Projeet
(KRRP) reestablished intermittent inundation of the river’s
floodplain by backfilling 12 km of the C-38 flood control canal
in 2001.” They compared floodplain vegetation maps of 2003
and 2008 aerial imagery to pre-channelization vegetation maps
from 1954, 1974, and 1996 in order to evaluate broad-scale
vegetation responses to Phase I restoration. Their results showed
that “wetland plant communities expanded rapidly, more than
doubling in area within 2 years after completion of Phase I, and
that by 2008 wetlands had nearly recovered to pre-channelization
levels.” Prior to channelization, much of the floodplain was
dominated by a broadleaf marsh (BLM) community associated
with extended, deep annual flooding, while shorter-hydroperiod
communities dominated the floodplain in 2003 and 2008. Prior
to restoration construction, the reestablishment of BLM was
predicted to be slow because suitable hydrology is dependent on
project components that will not be in place until all restoration
components are completed (projected for 2019). Hydrologic data
indicate that the duration and variability of floodplain inundation
have not yet achieved restoration targets over the entire Phase I
study area. Other factors affecting vegetation responses are likely
involved, including the age and viability of soil seed banks,
the rarity of relict propagule sources following the channelized
period, and competition from an invasive wetland shrub species.

CYANOBACTERIA ON INVASIVE AQUATIC PLANTS
IMPLICATED IN AVIAN VACUOLAR MYELINOPATHY.
PHYTOTAXA I8I(5):243-260.

The cyanobacterial species discussed in this article is in a
new genus of uncertain family assignment. The authors name the
new species Aetokthonos hydrillicola gen. et sp. nov. Research
into the taxonomy of a novel cyanobacterial epiphyte in locations
where birds, most notably bald eagles and American coots, are
dying from a neurologic disease (Avian Vacuolar Myelinopathy or
AVM) has been ongoing since 2001. Field investigations revealed
that all sites where birds were dying had extensive invasive aquatic
vegetation with dense colonies of an unknown cyanobacterial
species growing on the underside of leaves. Morphological
evaluation indicated that this was a true-branching, heterocystous
taxon falling within the former order Stigonematales. However,
16S rRNA gene sequence demonstrated that it did not match
closely with any described genus or species. More recent
sequence analysis of the 16S rRNA gene and associated ITS
region from additional true branching species resulted in a unique
phylogenetic placement distant from the other clades of true-
branching cyanobacteria. [Excerpts adapted from the article.]

Mosaic Plant, Ludwigia sedioides

By Dr. William T. Haller, Acting Director

Photo by Scott Zona

In the past five to seven years, the Southeastern United States
has seen a tremendous increase in the spread of the floating
leaved plant, Nymphoides cristata (crested floating heart) which
is widely used in the water garden industry. Florida has not had
problems with the native Nymphoides aquatica, but N. cristata
is proving to be very difficult to control. In the past decade or
so, Ludwigia sedioides has been sold in the ornamental industry.
We can And little information on its biology or growth other than
anecdotal information on water garden suppliers’ websites which
mention it as “...an easy grower, spreads rapidly, great for surface
coverage, grows in full sun to partial shade... ” etc. It has not been
noted in natural waters of the U.S., but it apparently can grow
into USDA hardiness zone 8 which encompasses the entire gulf
coast region of the country. Other Ludwigia species are a problem
in the U.S., including Ludwigia hexapetala and L. grandiflora.

Ludwigia sedioides

We obtained and planted 15 Z. sedioides plants in a 900 liter tank
and three months later the tank contains well over 100 plants that
nearly cover the entire water surface. A graduate student at the
CAIP is considering comparing the competiveness and biology
of L. sedioides to the known invasive Nymphoides cristata. Any
information from our readers will be appreciated. Please contact
William T. Haller at whafler@ufl.edu.

14th International Symposium on Aquatic Plants

The 14th International Symposium on Aquatic
Plants will be held in the beautiful Playfair Library in
Edinburgh, the historical capital of Scotland, between
14-18 September 2015. The aim of the conference
is to promote debate in all issues relating to science
and management of aquatic and riparian vegetation.
Ten special sessions are being organized, including a
session on Vegetation and Dams.

The meeting has been arranged under the auspices
of the International Society of Limnology (SIL) and
the European Weed Research Society (EWRS). An
International Scientific Committee will oversee the
conference and its outputs.

For more information, please visit the website. We will
be tweeting regular updates on the conference from
our twitter account using the #aquaticplantsl5 hashtag.

EDDMapS - Early Detection and Distribution Mapping System

EDDMapS is a web-based mapping system for documenting invasive species distribution. It is fast, easy to
use and doesn't require Geographic Information Systems experience. It was launched in 2005 by the Center for
Invasive Species and Ecosystem Health at the University of Georgia to develop more complete distribution data of
invasive species across North America.

The goal of EDDMapS is to maximize the effectiveness and accessibility of the immense numbers of invasive
species observations recorded each year. As of November 2014, EDDMapS had over 2.6 million records.

EDDMapS combines data from other databases and organizations as well as volunteer observations to create
a North American network of invasive species distribution data that is shared with educators, land managers,
conservation biologists, and beyond. This data will become the foundation for a better understanding of invasive
species distribution around the world.

Users simply enter information from their observations into the standardized online data form which allows
specific information about the infestation and images to be added. Data entered is immediately loaded to the
website, allowing real time tracking of species. Being able to see the current data of a species as it moves into a
new area helps to facilitate Early Detection and Rapid Response (EDRR) programs which can help stop or control
an invasive species before it becomes an unmanageable problem.

Free smartphone apps make identifying, collecting and reporting the invasive species across North America even
easier. Online training videos make learning to use them quick and easy.

All data is reviewed by state verifiers to ensure accuracy. The data is made freely available to scientists,
researchers, land managers, land owners, educators, conservationists, ecologists, farmers, foresters, state and
national parks.
