American Chestnuts in the Field

By the 1950s, two non-native pathogens had killed almost all American chestnut trees. “There’s a lot of interest in breeding a chestnut that looks like American chestnut with the disease resistance of Chinese chestnut,” says U.S. Forest Service research forester Stacy Clark. “However, there hasn’t been much research on reintroducing disease-resistant trees to the forest.”…  More

Oaks, an Unrecognized Ally in Longleaf Pine Restoration

Longleaf pine ecosystems are among the most threatened in the U.S., and managers across the southeast are prioritizing longleaf restoration. The conventional approach calls for removing hardwood trees such as oak. “Hardwood reduction techniques are commonly deemed necessary for ecological restoration of longleaf pine ecosystems,” says U.S. Forest Service research ecologist Louise Loudermilk. “Hardwoods are…  More
