GAINESVILLE, Fla. — A few bugs may be able to chew up some cogongrass, a noxious weed that elbows out pasture grass, golf course greens and valuable ecosystems, a University of Florida Institute of Food and Agricultural Sciences researcher says.

A worldwide research team led by UF/IFAS entomology professor James Cuda and retired entomology professor Bill Overholt found species in Japan, East Africa and Indonesia that might help in the battle against cogongrass.

Among the arthropods they found, Cuda and his team discovered a midge from Indonesia that attacks cogongrass. Cuda and his team are focusing on the Orseolia javanica midge that causes cogongrass to produce linear galls at the expense of leaves. However, when scientists brought the arthropods back to the quarantine facility at the UF/IFAS Indian River Research and Education Center in Fort Pierce, Florida, they did not mate and increase in population.

GAINESVILLE, Fla. — As Florida Arbor Day approaches on Jan. 20, University of Florida Institute of Food and Agricultural Sciences Extension and research faculty are holding special commemorations and studying how to ensure trees help our environment and economy.

“Arbor Day is a great time for everyone to be reminded of the importance of trees and forests in their everyday lives and to contribute to the approximately 70 million trees that are planted each year in Florida for reforestation,” said Tim Martin, professor and co-interim director of the UF/IFAS School of Forest Resources and Conservation.

“Wood harvested from Florida’s forests is the largest agricultural commodity in the state,” Martin said. “But these forests provide much more than just paper and boards. Clean water and air, wildlife habitat, recreation opportunities, carbon sequestration, and biodiversity are a just a few of the important benefits that forests provide for us all.”

In fact, UF/IFAS researchers have calculated that a typical acre of Florida forest provides more than $5,000 of services to the state’s residents each year, with just 7 percent of that value from timber, he said.

GAINESVILLE, Fla. — It took a few years for Buzz Eaves to notice that tropical soda apple shrubs were overtaking his 1,200-acre cattle ranch near Fort Pierce, Florida. The prickly plant, with fruit the size of a golf ball and the color of unripen watermelon, was creating a barrier to the cattle’s grazing ground and displacing native plants.

“I was spending close to $6,000 a year on fertilizer and it wasn’t working that well,” Eaves said. “Then I heard about a program through the University of Florida that helps get rid of invasive species, so I turned to the school for help,” Eaves said. “It was the best thing I ever did.”

The UF Institute of Food and Agricultural Sciences joined a dozen other organizations to form the Florida Invasive Species Partnership (FISP). The members work across boundaries to address invasive species challenges across the state, said Chris Demers, UF/IFAS Extension statewide program manager.

FISP began as a working group to address invasive species on state and federal land. The program expanded to include privately owned land, Demers said. “UF/IFAS Extension faculty provide various resources on invasive species, control and prevention,” he said. “We work across all species, plants, animals and fungus.”

GAINESVILLE, Fla. — Global climate change has already impacted every aspect of life on Earth, from genes to entire ecosystems, according to a new study by the University of Florida Institute of Food and Agricultural Sciences and in cooperation with a broad international partner group, published in the prestigious journal Science.

“We now have evidence that, with only a ~1 degree Celsius of warming globally, major impacts are already being felt in natural systems,” said study lead author Brett Scheffers, an assistant professor in the UF/IFAS department of wildlife, ecology and conservation. “Genes are changing, species’ physiology and physical features such as body size are changing, species are shifting their ranges and we see clear signs of entire ecosystems under stress, all in response to changes in climate on land and in the ocean.”

During this research, Scheffers, a conservation ecologist, collaborated with a team of researchers from 10 countries, spread across the globe. They discovered that more than 80 percent of ecological processes that form the foundation for healthy marine, freshwater and terrestrial ecosystems already show signs of responses to climate change.

“Some people didn’t expect this level of change for decades,” said co-author James Watson, of the University of Queensland in Australia. “The impacts of climate change are being felt with no ecosystem on Earth being spared.“

GAINESVILLE, Fla. — When veterinarian Bill Bennett first bought his 1,200 acres of land in Levy County, he wasn’t sure what he would do with it. “I didn’t know anything about working the land, and I wasn’t sure what I wanted to do,” he said.

Bennett heard about the Florida Forest Stewardship program—a collaboration of the University of Florida Institute of Food and Agricultural Sciences and various state agencies—and decided to give organizers a call. Chris Demers, a UF/IFAS Extension program manager who oversees the university’s participation in the program, suggested that Bennett attend workshops to gain knowledge.

“I knew I loved pine trees, but I had absolutely no knowledge of how to go about building a pine tree plantation,” Bennett said. “Everything I know, I learned through the stewardship program or through other participants. It has been invaluable to my success as a landowner.”

The Florida Forest Stewardship program was created in 1990 by the U.S. Forest Service to encourage private landowners to manage their forest resources for multiple benefits, said Demers, who is with the UF/IFAS School of Forest Resources and Conservation. “UF/IFAS’ role is to coordinate educational programming and outreach,” he said.

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers, who have already seen ambrosia beetles damage part of Florida’s avocado crop, know that more of the species will come from Asia in the next decade. Anticipating their arrival, UF/IFAS researchers set up a hypothetical invasion of the beetle, and found out that loblolly pine owners in the South could lose up to $17 billion in trees in 20 years.

Private companies use loblolly for timber production. Small landowners also harvest and sell some of their loblolly pines, said Andres Susaeta, a research assistant scientist in the UF/IFAS School of Forest Resources and Conservation. But small landowners are also interested in aesthetics, preserving the environment and passing the land on to their heirs.

For the study, researchers wanted to look at the economic impact of anticipated invasions of more ambrosia beetles from Asia into the southern United States. Invasive wood borers, such as the ambrosia beetle, transmit disease-carrying fungi to several North American trees, and it’s not clear whether trees such as pines will face similar threats in the future, the researchers said.

Even though the scenarios were hypothetical, Andres Susaeta, a research assistant scientist in the UF/IFAS School of Forest Resources and Conservation, said the situation could be all too real.

GAINESVILLE, Fla. — The PINEMAP project, based within the University of Florida Institute of Food and Agricultural Sciences, devoted five years to helping the Southeastern planted-pine industry prepare for future production challenges. Now, PINEMAP is being honored with a prestigious national award from the United States Department of Agriculture.

On Thursday, Oct. 6, the USDA National Institute of Food and Agriculture, or NIFA, announced that PINEMAP would receive one of three 2016 NIFA Partnership Awards presented nationwide. The award recognizes PINEMAP for its outstanding performance integrating and fulfilling the education, Extension and research missions common to all land-grant universities.

The award confirms yet again the impact of UF/IFAS programs for one of the state’s most important industries, said Jack Payne, UF senior vice president for agriculture and natural resources.

“Planted pine is cultivated on about 20 million acres throughout the Southeast. This industry is enormously important both economically and environmentally, and the work of PINEMAP was crucial to help secure the industry’s future,” Payne said. “Our UF/IFAS faculty members have shown exemplary leadership and scholarship; this honor is richly deserved.”

PINEMAP involved UF and 10 other southeastern U.S. land-grant institutions, as well as numerous collaborators from government agencies and private industry. The project was launched in February 2011 after leaders obtained one of three $20 million grants awarded concurrently by USDA as part of its Coordinated Agriculture Projects program, meant to strengthen vital domestic crop-production industries.

UF/IFAS study: Good tree care should yield environmental benefits

GAINESVILLE, Fla. — Trees shade our homes and help clean the air of our cities. However, their production in the nursery and maintenance in the landscape requires energy and material resources. Some of those processes are mechanized and release greenhouse gases like carbon dioxide.

Understanding this balance between tree environmental costs and benefits is crucial to those who plan and plant urban forests as it can help inform species selection, site development and prescribed care measures, says a University of Florida Institute of Food and Agricultural Sciences researcher and UF/IFAS Extension specialist.

In addition to providing shade, trees take in carbon dioxide – a greenhouse gas – and convert it and store it as carbon in their woody tissues. Trees generally provide the greatest environmental and economic benefits as they mature and grow to a significant size, said UF/IFAS environmental horticulture assistant professor Andrew Koeser.

In a newly published study, Koeser and Aaron Petri of the University of Illinois used a concept called “carbon neutrality” to examine tree benefits. When trees start storing more carbon than they emit – offsetting the amount spent by nurseries and foresters in tree care, that’s called “carbon neutrality.” That care can include planting, water, pest control, mulching, pruning and more.

“In general, the bigger the tree, the more environmental benefits you receive. Over time, the benefits of a tree finally equal its associated costs, with regard to carbon balance,” Koeser said. “I like to think of this as the tree paying back the environmental debt. If the tree doesn’t get to this point, it is emitting more carbon dioxide than it’s taking in and does a disservice to the environment.”

GAINESVILLE, Fla. — If a city plants trees near a residential area, most homeowners value the likely subsequent boost to their property values, a new University of Florida Institute of Food and Agricultural Sciences study shows.

And they’re willing to pay an average of $7 more per month in taxes for public trees planted in their city.

In the UF/IFAS study, 1,052 surveyed Florida homeowners said they’d like the trees on their land to provide shade and to be healthy, but they’d prefer an increase of $1,600 in their home’s value.

Residents were separated into two surveys. One asked them to consider a hypothetical home improvement project to better the trees on their property, while the other asked a similar referendum question regarding a city program that would increase their utility tax to increase urban forests in public areas near their homes. There were 526 responses to each survey.
