We are always happy to have “guest-authors” who give us an insight into their work. Carrie Ewing, PhD Student at The Ohio State University, is currently researching tree genetics to determine the plant pathogen(s) that are causing beech leaf disease (BLD), a new and seemingly lethal disease affecting American beech trees (Fagus grandifolia).
The disease was first discovered in forests in the northeastern United States and parts of Canada. John Pogacnik, a biologist at Lake Metroparks in Ohio, first observed BLD in 2012 in northeast Ohio, U.S.A. The disease has been spreading rapidly and has now affected forests in Ohio, Pennsylvania, New York State, and Ontario, Canada.
