Center Director's Corner
We are pleased to announce that a new UF/IFAS budget initiative to promote profit-
able and sustainable alternative cropping systems will be forwarded through the legisla-
tive budget request process. This initiative will provide for improvements and identifi-
cation of high cash value vegetable and floriculture crops with an emphasis on pest
management production and marketing techniques that will enhance IFAS' ability to '"t
attract additional funds from statewide groups. In addition, it will promote improved
sustainability by preserving and enhancing soil, air, and water resources while produc- \
ing adequate agronomic and alternative crops. SWFREC items included in this initiative are recurring
funds for a new technician position, as well as operating dollars for high-priority projects. We will pro-
vide updates on this initiative as it moves through the legislative process.
Special thanks to Ron Hamel, executive vice-president and general manager of the Gulf Citrus Growers
Association (GCGA), for his efforts to promote UF/IFAS budget initiatives throughout southwest Florida.
The grassroots support of Ron, GCGA grower members, and other industry representatives continues to
assist the SWFREC and enable our faculty and staff to improve effectiveness in ir. .r r. l, ri needs of our
Interviews and seminar sessions for candidates for our new citrus physiologist position will be scheduled
within the next eight weeks. Schedules will be posted on the Citrus Mechanical Harvesting Web site at

Project Targets Future Wildlife Crossing Plans
A research project just completed in August, which in part was directed by Dr. Marty Main, SWFREC
S-1.lIt1. ecologist, and facilitated by Ginger Allen, SWFREC senior biological scientist, will help to
determine potential sites for .1l11,t crossing structures along several high-traveled roadways in south-
west Florida's eastern Collier County near Immokalee.
The study was funded by the National .........
Wildlife Federation, Cit ygatr, and .
Barron Collier. Cooperating research- s" 1 .
ers on the project were Dr. Reed Noss
and Dr. Daniel Smith with the Univer-
sity of Central Florida in Orlando. .
The project's premise: Because road- o
ways are among the largest threats to ,
, -1.11t. tl.11,t. crossing structures 11 I .I
are needed at selected locations along .L.
roads to enable, .111.. to successfully
cross highways and maintain connec-
tivity and gene flow within and among p, tI r.....
The purpose of this project was to analy .!l !I... -.. r I.r
terns (particularly large animals, include 2 rl, I ,. p..! I "r.. I -, ,.
black bear) along areas of State Road 29, L.I -.. .- I ', I11!.
was accomplished by: 1) monitoring thE . I., r.. I. 1 .... I Ii I....-
kill; 2) conducting 1 1. 1t1. track monitoring; and 3) setting up re-
mote infrared camera stations at selected sites to monitor large animal crossings on or approaches to
Transects (long, narrow strips of land) were established alongside the selected roadways by clearing
them of all '. r .ri..i.. These areas then were monitored twice weekly between January-August 2006.
"We stopped at the transects to check for animal tracks," explains project field technician David Ham-
mel. "We always :I 1-, 2. .1 a track in the direction the animal was going,
.- that we could document if the animal had likely just crossed the
1i, or was getting ready to cross the road."
I i lt transects were checked for tracks up to three times a week and
i 1i. .v ed clean twice weekly. In addition to flagging found tracks, infor-
!n. ron about each track found was entered onto a log sheet by species,
I tion (using GPS equipment), and direction of travel. Road-kill
h!,! .; were logged the same way. And photos from the infrared cam-
ii -. placed at each transect were downloaded on a weekly basis.
I ,t1 from the project are still being summarized; however, prelimi-
i, i.1 results depict more than 70 animal species recorded, including the
t.- allowing that are listed by the state of Florida as threatened: Florida
Senior biological scientist Ginger black bear, Florida sandhill crane, and southeastern American kestrel.
Allen conducts tissue sampling on a
road-kill coyote. And the endangered Florida panther also was documented.
"Animals are like people," David says. "They want to travel the path of least resistance, which, unfor-
tunately for them, often happens to be across highways. We hope that when, for instance, the county
makes future plans to widen one of these highways, they'll utilize this data to create habitat crossings in

Groups Enjoy Educational Visits to SWFREC
Two groups visited the SWFREC in September to learn about the facility and hear from specific staff mem-
bers regarding current projects.
A field trip brought twenty-three .i.rl-. ; ,1.. science students from Oakridge Middle School in Naples to the
center for a two-hour visit. Along with five adults and teacher Georgia Stamp, the group heard from the F'
following post-doctoral research associates:
* Dr. Ronald French, Plant P.rl,. .1.. '. program, who presented information about various types of fungi
and viruses and gave students a close look at Petri dish samples under a microscope.
* Dr. Jawwad Qureshi, Entomology program, who showed examples of "good" and "bad" bugs, provided
information about biological control, and enabled examination of bugs under a microscope.
Petri dishes are passed around to

up-close looks at bugs and fungi.
that are placed in a field to monitor water intake and usage by plants, thereby determining the actual ls a b a
irrigation needs of plants in the field. He also spoke about growing vegetables on the sandy soils of
southwest Florida versus other areas.
A delegation of twenty-four individuals from the Yantai Province in China visited the center to learn about
citrus and vegetable production in southwest Florida. The group included agricultural growers and manag-
ers, as well as governmental representatives of the agricultural industry in China. The stop was organized by
Dr. Daniel Borgia, a faculty member and director of the China Studies Institute at Florida Gulf Coast Uni-
versity, and included the following SWFREC staff members:
+ Associate director Dr. John Dunckelman, who provided
an overview of the center and statistics on citrus and
vegetable production in southwest Florida. t
* Mark Terrell, a member of the Department of Plant In-
dustry who helps oversee the SWFREC Budwood Foun-
dation grove, who described the state's citrus budwood
program and demonstrated the budding process.
* Vegetable horticulturalist Dr. Kent Cushman, who gave
an in-field overview of vegetable production in south-
west Florida, including information about transplant Dr. Kent Cushman discusses vegetable transplant produc-
production. tion with the Chinese agricultural delegation.
