Seed Size & Predation

Among their many benefits, prescribed fires can protect southeastern pine woodlands from encroachment – the process of fire-sensitive species expanding into fire-maintained woodlands. Because fire is important for longleaf pine regeneration, forest researchers have studied the effects of flammability on the pine woodlands. In a recent study published in in Applied Vegetation Science, USDA Forest…  More 

Hemlock Woolly Adelgids & Their Predator Beetle, Laricobius nigrinus

Laricobius nigrinus is a small beetle that eats an even smaller bug – the hemlock woolly adelgid, or HWA. Since 2003, Laricobius has been used to help control HWA. But the beetle, which is native to western North America, is only active during the fall, winter and early spring. Recently, USDA Forest Service research entomologist…  More 

Acorns and Their Predators

Acorns aren’t only for squirrels. They serve as a food source for a variety of wildlife, such as mice, deer, and turkeys. This presents somewhat of a problem for oak trees – acorn producers – because their future depends on acorns surviving and germinating to become the next generation. A recent study by USDA Forest…  More 

Protecting White-Tailed Deer Fawns

Wild animals are often immersed in a mortal struggle. For white-tailed deer fawns, the struggle entails hiding from predators like coyotes. “Fawns are highly vulnerable to coyote predation,” says John Kilgo. Kilgo is a research wildlife biologist at the U.S. Forest Service, and he recently coauthored a study about coyotes, fawns, and land cover. Coyotes…  More
