RuC Newsletter
...for alumni and friends

Research at the SFRC
Research is one of the three
central missions of all
Land Grant universities,
along with teaching and
Extension. The University of
Florida is recognized as a
Tier 1 research university
and one of a very few
universities in the south
that holds invited
membership in the
American Association of Universities. The National Science
Foundation ranks UF 17th among all universities in the US for
total research funding from contracts and grants, outranking
the University of California at Berkeley and approaching MIT
and Duke.
The faculty and staff in the School of Forest Resources
and Conservation play an important role in the UF/IFAS
research enterprise, conducting important, nationally
recognized research programs that consistently rank in the top
among IFAS academic units for total funding. Each year SFRC
faculty secure $3 to $5 million in research funding from
contracts and grants, amounting to approximately $200,000 per
faculty member. These external funds, so essential to developing
new knowledge, come from a variety of competitive sources
including federal and state agencies, industry, NGOs and private
Research programs conducted by SFRC faculty and staff
are extremely diverse, embracing both applied and basic

research and technology development and reflecting the diverse
needs of our stakeholders. Our research spans all biological
scales from molecular genetics to landscape ecology and all
social and geographical scales from individuals to local
communities and the world.
Beneath this diversity lies the common thread that
characterizes all SFRC research.... the development of
"knowledge with a purpose" not just "knowledge for knowledge's
sake". This "problem solving" research is central to the Land
Grant mission as we seek to discover new knowledge that is
essential for the development of science-based policies,
regulations, tools, technologies and management decisions. In
this regard, SFRC research aims to: (1) Address key societal
issues; (2) Enhance economic returns and global competiveness;
(3) Improve the health, sustainability and environmental values
of our forest and natural resources.
This newsletter focuses on some recent results of SFRC
research. All SFRC research is highly collaborative with staff,
post-docs, graduate students, industry, state agencies and many
others all working together. While it is not possible to list all
those associated with each study, a faculty member is listed
after each highlight as a contact if you want more information.
We hope these research highlights are useful to you
and that you will send us your ideas, priorities and problems
for future SFRC research projects. Your guidance will be
important in helping to ensure that SFRC research continues to
address important societal, economic and environmental
problems and opportunities.

Research highlights from the SFRC

Human Dimensions...
-> Teachers can use stories and books about natural resources
to teach reading through science if they are given worksheets and
exercises that engage students in reading and writing skills.
Martha Monroe
-> OHV recreation at the Croom Motorcycle Area
on the Withlacoochee State Forest generates
$21.6 million annual income and 318 jobs in
four counties. Janaki Alavalapati and Taylor
-> Most users of off highway vehicle (OHV)
recreation on the Ocala National Forest are well educated and
have high incomes. They participate in OHV recreation in the
Ocala to experience nature (96%), spend time with their friends
and family (94%), and reduce stress and tension from everyday
life (93%). TaylorStein

Genetics and Tree Improvement...
-> Genetic gains measured in
block plots of slash pine verify
the accuracy of genetic
predictions from single-tree
progeny tests for volume growth
and fusiform rust resistance.
This allows breeding values
predicted from progeny tests to
be safely extrapolated to a stand
level basis. Dudley Huber
-> Genetically improved slash pine plantations in low rust hazard
areas can show verified genetic gains for volume per acre of more
than 40% over wild seed. With good fusiform rust resistance in
areas prone to high rust infections, the volume-per-acre gains
from using highly improved sources can double that of unimproved
material. Dudley Huber
-> Analysis of the first complete DNA sequence of a forest tree
(Populus) revealed as many as 45,000 genes, about the same
number as humans, with at least 20,000 of these genes being
active during stem development and wood formation. MatiasKirst
and John Davis
-> Natural genetic resistance of loblolly pine to fusiform rust and
pitch canker diseases is controlled by entirely different genes for
the two diseases; however, about 10% of genetically improved
families happen to be highly resistant to both diseases and
have excellent growth rates. John Davis and Dudley Huber
-> A newly discovered, naturally occurring allele in Populus leads
to a reduction in lignin content by almost half, while also resulting
in faster growth and higher cellulose content. This combination
will be highly favorable for bioethanol production. Matias Kirst
-> At 7 years, growth was higher in mixed- versus pure-family
stands for faster-growing families, suggesting that faster-growing
families grew larger at the expense of the slower-growing ones
when growing in an intimate mixture. Christie Staudhammer, Eric
Jokela and Tim Martin

-> Use of integrated LiDAR and GPS/IMU
systems increase the safety and resolution of
shoreline and harbor surveying and can be ,
used to improve the accuracy and
completeness of the nation's nautical charts.
-> The integration between proprietary GIS
services and open access technology (e.g.
Google Earth) is gaining momentum in
forestry applications. Amr Abd-Elrahman

Production and Family Forests...
-> Southern pine plantation forests have among the highest
terrestrial ecosystem carbon sequestration rates yet measured,
as much as 3.5 tons/ac/yr. Tim Martin
-> Some families of slash and loblolly pine are more responsive
than others to increasing silvicultural intensity, highlighting the
opportunity to increase stand volume production by planting
responsive families with site-specific silvicultural treatments.Eric
-> Higher levels of pitch canker incidence and
disease severity in slash pine plantations are
S p associated with the higher levels of plantation
nitrogen found in proximity to poultry houses.
-> Both genetics and silvicultural treatments
affect the stiffness of juvenile corewood in
loblolly pine. Planting certain families of pine
that are naturally stiffer and planting them at
higher densities can increase juvenile
corewood stiffness by 40-60%. Gary Peter
Fire and Water...
-> Ocala sand pine has a greater capacity to survive high-
intensity crown fire than previously believed, suggesting that
prescribed fire can be used to manage wildfire hazard without
complete loss of timber revenues. Leda Kobziar
-> Tree ring chronologies from living and long-submerged longleaf
pine in Florida's panhandle can also be applied to other parts of
Florida to increase understanding of historical patterns of fire,
droughts and hurricanes. Leda Kobziar
-> The primary source of
phosphorus (P) loading
into hyper-eutrophic
Newnans Lake comes from
naturally occurring
geologic sources not from
pine silviculture. Matt
-> NIR spectroscopy (NIRS)
can predict functional
attributes (C, N, P, Ca, Al,
Fe) of saturated soils and sediments, paving the way for direct
field measurement with portable spectrometers. Matt Cohen

Longleaf Pine...
-> Ground-based LiDAR (a
laser-based measuring
system) provides a novel
technique to quantify fuel bed
characteristics. The data
permit better modeling and
prediction of fire behavior in
longleaf pine forests. Wendell
-> Longleaf pine regeneration
in hurricane-impacted areas
tends to be clustered into several distinct patches ranging in size
from 0.1 to 1 acre. An alternative to row planting in restoration
efforts could include planting seedlings within unique patches
in order to mimic the natural landscape of longleaf pine
ecosystems. Kimberly Bohn
-> Reintroduction of fire alone is not always sufficient to restore
the understory communities in longleaf pine flatwoods. Seeding
or planting of understory species may be necessary if there is
not a viable seed bank. Shibu Jose

Tropical and International Forests...
-> Policy initiatives that promote ethanol production have increased
the areas under sugar cane cultivation in Brazil and corn
cultivation in the USA. Unfortunately, this could lead to increased
deforestation in the Amazon region as displaced soybean
cultivation and cattle ranching are pushed further into the forest.
-> Current best practices for timber production from Brazil's native
Amazon forests minimize the environmental impacts of harvest
operations, but do not ensure that the volume of timber removals
can be sustained in future harvests. Daniel Zarin
-> Brazil nuts are solely harvested in the wild from mature
Amazonian forests, and this single species is credited with the
protection of millions of hectares of intact rainforest in Brazil,
Bolivia and Peru. Research in three communities indicated that this
forest use is sustainable, meaning that despite high current nut
(seed) collection intensities of up to 71% of the annual crop, natural
regeneration is sufficient for population persistence in this
collection hub. Karen Kainer and Christie Staudhammer
-> The tropical palm Mauritia
flexuosa has high ecological
and economic value, but
currently some wild
populations are harvested
excessively. Matrix
population models were
developed to investigate the
potential for sustainable
harvest. Wendell Cropper
-> Mexico's reformed
Constitution of 1992 allows Photo by Jennifer Holm
privatization of communal property
(called ejidos). Those ejidos with successful community forestry
operations are less likely to convert to private, individual property.
Grenville Barnes
-> Development of wildlife conservancies among communities
surrounding parks in Southern Africa allows community members
to derive a livelihood from the park and provides the opportunity
to develop democratic local governance structures. Grenville Barnes

-> Producing ethanol from southern pine plantations uses less than
half the water and less than 1/10 the nitrogen that is used to
produce the same amount of ethanol from corn. Matt Cohen
-> Residues from logging, urban
S wood waste, and trees harvested
during thinning operations in
overstocked pine stands can provide
the majority of woody biomass
needed to produce 120 megawatts
per year of energy for three north
Florida communities. Douglas Carter
-> Adoption of Renewable Energy
Portfolio Standards (REPS) by states
in the U.S. is not random, but rather is influenced by the state's
education level, political party dominancy, gross state product and
growth rate of population. JanakiAlavalapati and Douglas Carter
-> Thinning small diameter trees for bioenergy improves the
profitability of non-industrial private forest owners (NIPF) in
Florida by 15%, and this increase more than doubles if the benefits
of reduction of wildfires and pest outbreaks associated with
thinning are considered. JanakiAlavalapati

Invasive Exotics...
-> Cogongrass (Imperata cylindrical) was found to invade forest
communities irrespective of their species richness or diversity.
However, the presence of certain species, such as broomsedge
(Andropogon virginicus), enhanced the community resistance
to cogongrass invasion. Shibu Jose
-> Control of cogongrass in slash pine forests by a single
landowner generally does not make economic sense without
neighborhood landowners' participation. Janaki Alavalapati,
Shibu Jose and Douglas Carter
-> The incredibly rapid
spread of an exotic pathogen-
insect complex, commonly
known as Laural Wilt
Disease, threatens the future
of the red bay (Persea
borbonia) species. Potential
natural resistance to the
pathogen has been observed
in native red bay populations where widely scattered
individuals survive devastating epidemics. Jason Smith
-> Combinations of herbicides that inhibit the formation of
amino acids in plants provide the best control of the invasive
non-native Japanese climbing fern (Lygodiumjaponicum) while
minimizing adverse impacts to associated vegetation. Pat

Conclave 2008 in the Swamp
Every year, forestry clubs from 15 university forestry programs in the southeastern U.S. come together to compete in the Association of
Southern Forestry Clubs' (ASFC) Conclave. Since 1957, this gathering brings several hundred undergraduate forestry students together
to compete in traditional lumberjack style events like log birling and pole felling, as well as technical events such as dendrology and
timber estimation. Conclave provides opportunities for future natural resource professionals to network with other students and
visiting professionals from across the region, to develop organization and leadership skills, and to have a plain old good time. Most
foresters educated in the region have fond memories of their own participation in Conclave as undergraduate students.
Hosting responsibilities rotate among ASFC members; the UF Forestry Club will host in April, 2008.
Hosting an event with over 250 students and 20-30 faculty sponsors participating in 22 events over a
three day period is a major undertaking, and SFRC students, faculty and staff are hard at work to
make Conclave 2008 a memorable event. Information about Conclave can be found at this website:
http ://sfrc. ufl.edu/Conclave2008/
