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.

AUGUSTINE, Fla. — Henry Keating, 15, and Cayla and Jeremy Smith, 15 and 17, can tell a fir tree from a spruce — no small feat for three kids who grew up in St. Johns County, Florida, where firs and spruces don’t grow.

As part of the UF/IFAS Extension St. Johns County 4-H forestry team, it’s been several years since these three could walk into a forest and simply see “trees.” Instead, they see features such as leaf shape and branching pattern, clues to the trees’ species. For example, “spruces have rounder needles, while firs have flatter ones,” said Jeremy.

Keating and the Smiths won this year’s Florida 4-H state forestry competition and are now headed to the National 4-H Forestry Invitational in Jackson’s Mill, West Virginia. The competition is set for July 31 to Aug. 4.

The St. Johns team will compete with other 4-H teams from across the country, demonstrating mastery of various skills, such as estimating the amount of timber in a tree and planning the development of forested land. They will also need to identify 81 tree species, including fir and spruce, nearly twice the number of trees they had to know at the state level.

UF/IFAS Professor Ed Gilman: A legacy of tree growth

Topic(s): Announcements, Environment, Extension, Forestry, IFAS, Research, Weather

 

Ed Gilman, a professor of environmental horticulture with the University of Florida's Institute of Food and Agricultural Sciences, examines the trunk of a tree toppled by hurricanes this year. He said the most important thing to remember in an urban environment is the location of the trees, planting them so their roots are not affected buildings, curbs, driveways or sidewalks.

GAINESVILLE, Fla. — Among his legacies, Ed Gilman wants to make sure trees don’t snap in Florida’s tropical storm-force winds.

When Gilman retires this month from the University of Florida Institute of Food and Agricultural Sciences, he can point at several crowning achievements in his career.

Now, at age 62, Gilman will spend more time with family, of course, and do more woodworking, “working with dead trees instead of live trees,” he deadpanned.

GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers will introduce genetic biotechnology as a potential means to preserve forests at a national conference next week in Washington, D.C.

Jiri Hulcr, an assistant professor in the UF/IFAS School of Forest Resources and Conservation, and one of his doctoral students, Caroline Storer, will host the symposium at the North American Forest Insect Work Conference May 31 to June 3.

Hulcr sees this conference as an opportunity for the UF/IFAS forest entomology team to disseminate innovative solutions to maintain tree health.

“Exploring the use of biotechnology in tree health protection is important to us, because we are increasingly running out of other options,” Hulcr said.

Additionally, he said: “Trees and forests provide jobs and benefits for everyone. Yet, around city neighborhoods and rural forests, anyone can witness the diminishing health of trees. The culprit is exotic pests and diseases. Forget pollution or drought: It is destructive tree diseases and pests — imported by overseas travelers or business people — that are nearly eliminating some tree species from our forests and orchards.”

UF/IFAS study could help cities improve tree planting

GAINESVILLE, Fla. — Heat from city sidewalks, streets, and parking lots, along with insect pests, can damage trees planted in urban landscapes. Thus, it is critical to plant trees in the right places so they will do well in harsh urban environments, a University of Florida Institute of Food and Agricultural Sciences researcher says.

More than half the world’s people and 80 percent of the U.S. population live in urban areas. Trees benefit these residents by filtering the air, reducing temperatures and beautifying landscapes. According to a new study led by Adam Dale, a UF/IFAS assistant professor of entomology, these benefits are reduced when trees are planted in unsuitable urban landscapes. However, guidelines can be developed to lead urban tree- planting decisions in a more sustainable direction.

Dale spearheaded the study while at North Carolina State University in Raleigh, North Carolina. Previous research by Dale and his colleagues found that impervious surfaces raise temperatures, which increase pest abundance and tree stress, ultimately reducing tree health. He and his team examined the so-called “gloomy scale insect,” which feeds on tree sap and appears as small bumps on the bark of trees.

GAINESVILLE, Fla.— Arbor Day is approaching and Seffner, Florida, residents are geared up to celebrate with an Arbor Day mail art contest presented by the University of Florida Institute of Food and Agricultural Sciences Extension Hillsborough County.

National Arbor Day, April 29, is a time for the global community to come together and celebrate the importance of trees by planting new ones and taking care of the trees already in existence. Trees play an essential part in the ecosystem because they provide clean air and water as well as slow climate change. They also prevent species loss and alleviate poverty and hunger.

This year’s Arbor Day theme for the mail art contest is titled “I appreciate trees because…” Contestants will submit their art, along with their name, age and number, to the Extension office for a chance to be one of three winners. The categories are divided by three age groups: child, youth and adult. Three winners will receive a tree planting kit worth $100, and their art work will be displayed in the lobby of the UF/IFAS Extension Hillsborough County office.

The winners from each age group will be chosen before Arbor Day, and they must be present at Kerby’s Nursery on April 29 at 6 p.m. to receive their prizes.

GAINESVILLE, Fla. — When you think of wildfires, you may not think of wetlands. But the seldom-seen blazes may help some endangered species, according to a newly published study by a former UF/IFAS researcher.

Severe wetland fires — so rare they occur only a few times per century – also can change vegetation and patterns of water movement, said Adam Watts, who led the study as a post-doctoral researcher in the UF/IFAS School of Forest Resources and Conservation.

During a smoldering fire, wetlands can become deeper if the fires burn muck or peat soils.

“In some cases, this could help improve habitat for endangered species, such as wood storks,” said Watts, now a research assistant professor at the Desert Research Institute in Reno, Nevada. But wetland fires can also kill many trees and shrubs, causing changes to the vegetation that returns.

GAINESVILLE, Fla. — Two former doctoral students from the University of Florida Institute of Food and Agricultural Sciences are running a genetics startup company in Gainesville and recently were recognized by Gov. Rick Scott as “Young Entrepreneurs.”

Marcio Resende said he came up with the idea for RAPiD Genomics while in Brazil due to a demand from a forestry company that needed someone to do some genotyping for them. Several factors, including costs, kept him from pursuing the notion.

But when he came to the United States to pursue his doctorate, he started talking to Leandro Gomide Neves, a fellow doctoral student, and Matias Kirst, a professor of forest genomics at UF/IFAS. They decided to open RAPiD Genomics. At the same time, they teamed up with some colleagues to invent a genotyping method, which gave them extra motivation to pursue the idea of opening a business.

UF/IFAS study: Most homeowners can’t properly assess damage to their trees

Topic(s): Conservation, Environment, Extension, Families and Consumers, Forestry, Green Living, IFAS, RECs, Research, Safety

GAINESVILLE, Fla. — The next time a storm tears up your yard, let an expert assess the damage to any trees. A study from the University of Florida Institute of Food and Agricultural Sciences shows that homeowners perceive the risk of a damaged tree differently than trained professionals.

The survey of tree experts and homeowners in the Tampa Bay area assessed the perceptions of both groups when it came to assessing tree damage, said Andrew Koeser, an assistant professor in environmental horticulture and study author.

“While there are a number of factors tied to tree risk, most respondents were fixated on tree defects,” Koeser said. “Only experienced professionals considered other pertinent factors—namely whether the tree was actually a threat to a person, vehicle or house.”
