Regional Participants Gather at the Fourth Experimental Forest Workshop

About 30 USDA Forest Service scientists gathered in Raleigh, North Carolina this month for the fourth workshop in a series about reinvigorating the SRS network of Experimental Forest and Range sites. The group included 17 SRS scientists, in addition to FIA, EFR sabbatical recipients, university collaborators, and two partners from the Southern Region of the…  More 

The State of U.S. Forests

The U.S. forest products industry accounts for approximately four percent of the nation’s total manufacturing GDP, producing over $200 billion in products every year. To keep tabs on the condition and status of America’s forest resources over time, the USDA Forest Service Forest Inventory and Analysis Program compiles the official estimates for all public and private forest lands in…  More 

How Tree Diversity Affects Invasive Forest Pests

“Invasive insects and diseases pose both ecological and economic threats to our forest ecosystems,” says Qinfeng Guo, USDA Forest Service research ecologist. Guo is the lead author of a broad-scale study of U.S. forest data that examines the relationship between the number of native tree species and the number of nonnative forest pests. Across their…  More 

Trees in Protected Areas

Conservation goals range anywhere from aesthetics to survival. Among the most important of those is ensuring that an ecosystem is resilient to disturbances and provides as many different functions as possible. According to an assessment by a USDA Forest Service cooperating researcher, those qualities can be quantified using two metrics: rarity and evolutionary distinctiveness. Rarity…  More 

Workshop on Southern Experimental Forest Network

More than 20 representatives from SRS Experimental Forests (EF), Forest Inventory and Analysis (FIA), SRS leadership, and partner sites met on April 30 in Little Rock, Arkansas. “Their primary objective was to build on previous efforts, such as the field tours, and develop an implementation framework and plan for the network,” says Stephanie Laseter, EF…  More 

Family Forests Are the Ties That Bind the Landscape

Family forests have an enormous capacity to provide ecosystem services such as clean air and water, timber and nontimber forest products, wildlife habitat, and scenic beauty and recreation — benefits that stretch far beyond property lines. According to USDA Forest Service research, sustaining these services depends on not only the condition of individual family forests…  More 

The State of the Nation’s Forests

Forests are constantly changing with weather, disturbance, and conversion to other land uses, but how do we know if year-to-year changes are just a one-off or part of a larger shift? Annual summaries of forest health are key to our understanding, say the editors and authors that produced Forest Health Monitoring: National Status, Trends, and…  More 

Protecting Hardwood Resources

Trees provide clean air and water, wildlife habitat, and beauty. Trees are also vital to local economies. “In 2015, Kentucky had 193 hardwood sawmills,” says USDA Forest Service research forester Tom Brandeis. “That same year, Tennessee had 226 hardwood sawmills.” Each state produced more than 700 million board feet of hardwood lumber in 2015. Higher…  More 

Do Roads Drive Forest Plant Invasions?

Roads provide a means for moving people and products, but they can also allow hitchhiking organisms to spread. Some exotic invasive plants thrive on the disturbance created by road construction that displaces native plants. However, a new study led by Kurt Riitters, U.S. Forest Service research ecologist with the SRS Eastern Forest Environmental Threat Assessment Center, found…  More 

FIA Update on Alabama’s Forests

In the forests of Alabama you’ll find longleaf pine woodlands, bottomland swamps, sinkholes, and springs. You’ll see fox squirrels, indigo snakes, gopher tortoises, and pitcher plants. The Forest Inventory and Analysis (FIA) program of the U.S. Forest Service collects field data on forest resources across the state, visiting around 700 of the more than 5,600…  More
