Ethan Olson is the owner of Walburn Run Nursery located in Brockway, Pennsylvania. His main plant focus at his nursery is on fruit and nut trees along with berried shrubs and edible herbaceous plants. Presently, Ethan spends the majority of time growing and collecting the American chestnut (Castanea dentata). His mission is the preservation of a diverse chestnut germplasm in hopes of getting this once great species back into the environment as a productive component to the northeastern forest ecosystem. Ethan has a bachelor’s degree in landscape architecture from Temple University and is an avid outdoorsman.
