New Series of Science Updates on NTFPs From Trees

Trees provide food, medicine, and other things that people need. USDA Forest Service researcher Jim Chamberlain developed factsheets for eight species: Eastern black walnut (Juglans nigra) Fraser fir (Abies fraseri) Noble fir (Abies procera) Pawpaw (Asimina triloba) Persimmon (Diospyros virginiana) Pinyon pine (Pinus edulis) Sassafras (Sassafras albidum) Sugar maple (Acer saccharum) These trees provide fruit…  More 

New Resource on Invasive Species

Eastern hemlock, American chestnut, sassafras, redbay, every member of the ash family, and many others are plagued by non-native invasive species. A new book synthesizes current science on species invading U.S. forests, grasslands, and waterways. The book was published by Springer, and the entire book is available to download. The book covers invasive species of…  More 

FIA One-Click Factsheet Wins Agency Honor Award

Every year since 1930, scientists from across the USDA Forest Service team up with state agencies to survey the nation’s forests, as they have since 1930. The field crews are part of the Forest Inventory and Analysis program, or FIA, a national census of forest land and forest conditions. This massive campaign collects data on…  More 

Hardwood-Cypress Swamps, Unlikely Fire Hazards

In parts of the southeastern U.S., one unlikely forest type has great potential for extreme fire behavior: hardwood-cypress swamps. These shallow wetlands can work with their more frequently burned neighbors, pine flatwoods, to wreak havoc by easily igniting and sustaining tremendous wildfires, thus depleting carbon storage in these forests. Hardwood-cypress swamps and pine flatwoods are…  More 

FIA in the U.S. Virgin Islands

The 49th Annual Agriculture and Food Fair of the U.S. Virgin Islands, Agrifest, was held on the island of St. Croix in February. Agrifest is the largest agriculture and food explosion and celebration in the Caribbean – drawing thousands of fairgoers from around the world. USDA Forest Service scientists Tom Brandeis, Humfredo Marcano-Vega, and Kathleen…  More 

Fourth Inventory of U.S. Virgin Islands’ Forests

The forest and urban inventory in the U.S. Virgin Islands (USVI) is expanding. Through its Forest Inventory and Analysis Program (FIA), the USDA Forest Service has collected data in the USVI since the mid-1990s. FIA data on trees, soils, and other forest characteristics have been critical in establishing a baseline and understanding trends of forest…  More 

FIA Stakeholders Meeting

Across the nation, USDA Forest Inventory and Analysis collects data on forest ecosystems, including soils, microbes, land ownership, carbon, invasive plants, and of course, trees. Every two years, experts from the U.S. and beyond gather to share their knowledge. The 2019 FIA Stakeholders Science Meeting was held in Knoxville, Tennessee from November 19-21. The National…  More 

FIA Data Inform Studies on Land Use Conversions, Markets, and More

Strong forest markets protect forests by reducing conversion of forests to other land uses, according to a recent study. The study uses data from the Forest Inventory and Analysis program. “Across the Southeast and the rest of the U.S., FIA provides detailed observations of every aspect of the forest resource,” says John Coulston, a USDA…  More 

Assessing the Health of U.S. Forests

Forests are complex ecosystems. They are constantly changing as a result of tree growth, variations in weather and climate, and disturbances from fire, pathogens, and other stressors. The USDA Forest Service Forest Health Monitoring (FHM) program tracks these ongoing changes — every year, across the nation — as a forest health check up. The 2018…  More 

Uncovering Urban Forests

The scope of forest-pest risk analysis research is often limited to natural forests. Neglected are those tree communities called urban forests: trees within the boundaries of a city or populated area. Urban trees see a significant proportion of the impacts from invasive pests. Their unnatural distribution and close proximity to transported goods and other means…  More
