In this episode we interview two scientists from the US Forest Service about efforts to develop disease-resistant elm trees for riparian forest restoration. Both are principal investigators for the American elm disease resistance breeding and restoration program. Dr. Leila Pinchot is a restoration ecologist whose research focuses on the restoration of tree species impacted by non-native pests and pathogens. Dr. Kathleen Knight is an ecologist whose research focuses on the impacts and management of non-native pests and pathogens in forest ecosystems, specifically emerald ash borer and Dutch elm disease.
