New book on fire ecology and management across the U.S.

A comprehensive book on fire ecology and management in U.S. forests is now available. More than 70 experts wrote the book together, including researchers, land managers, and other experts from the USDA Forest Service. Other authors represented universities, non-governmental organizations and state and federal agencies. Forest Service scientist Katie Greenberg and Western Carolina University professor…  More 

Fires change forests

A study spanning four continents and 67 years suggests that frequent fire is causing grasslands to replace savannas. The effects of changing fire frequencies may take several decades to become substantial, reports the study led by Stanford University researcher Adam Pellegrini, with contributions from USDA Forest Service research plant physiologist Mary Anne Sword Sayer and…  More 

New story map for the Experimental Forest Network

Long-term research is conducted across the USDA Forest Service Experimental Forest Network. A new story map provides detailed information for each site in the SRS Experimental Forest Network. The story map: Discusses current and past research and highlights online resources, including a growing collection of digital datasets; Shows the ecoregion and type of forest community…  More 

Catchin’ bugs in the Lari-Leuco container

New containers make it easier to monitor Laricobius beetles and Leucopis silver flies, two important predators of hemlock woolly adelgids. USDA Forest Service managers and partners have released these predators throughout the range of eastern hemlock to help control the invasive adelgids. After two years, the sites are monitored to see if the predators have become…  More 

Linking tree water use and soil moisture

When more water is available, some tree species use much more of it. Loblolly pines growing near a stream used 65 percent more water than loblolly pines growing near the top of a hill, reports a new study led by USDA Forest Service researcher Johnny Boggs.  White oaks near a stream only had 12 percent…  More 

Handbook for 30-year-old bottomland oak stands

Southern floodplain forest landowners can benefit from a new USDA Forest Service handbook of silvicultural practices for oaks planted on former croplands. The practical volume outlines the methods – and supporting science – for managing stands to produce high-quality oak sawtimber, improve wildlife habitat through acorn production, or an integrated approach for both timber and…  More 

Longleaf pines & fire in the growing season

Prescribed fire every two years had no impact on the growth or survival of mature longleaf pines – even when prescribed fire was conducted in the growing season, finds long-term experiment. USDA Forest Service scientist John Willis led a study comparing stands of Pinus palustris burned in winter, spring, and summer. Summer lightning often ignites…  More 

Shortleaf Pine Plantings from 1980s Can Guide Restoration

About forty years ago, 155 plots of shortleaf pine (Pinus echinata) were planted in national forests across the USDA Forest Service Southern Region. The original purpose was progeny testing, but as decades passed, the study was largely abandoned. However, many of the stands remained and kept growing. In 2018, researchers evaluated 15 of the surviving…  More 

Webinar Series on Forests & Food Across the Globe

A new webinar series explores the value of the food and medicine forests provide. “Many Americans eat berries, nuts, and edible mushrooms from forests,” says Jim Chamberlain, USDA Forest Service researcher. Every year, hundreds of thousands of pounds of food are gathered from public lands. Chamberlain is organizing the webinar series as part of his…  More 

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
