Dave Pilz, is a Consultant and Writer, and owner of PilzWald (Forestry Applications of Mycology), in Corvallis, OR. He was formerly a Forest Mycologist with the Department of Forest Science at Oregon State University in Corvallis, OR, where he conducted research on harvested forest fungi, with an emphasis on compatible production of edible mushrooms in forests managed for timber and other amenities. This research focus evolved from 9 years of research with the Pacific Northwest Research Station (USDA-Forest Service) on the Productivity and Sustainable Harvest of Edible Forest Mushrooms. Research projects entailed collaboration with numerous landowners, forest managers, and harvesters to test monitoring protocols for matsutake, chanterelle, and morel mushrooms and to investigate how silvicultural choices effect their productivity. More generally, David's expertise extends to the broader topic of Non-timber Forest Products, starting with his involvement in issues surrounding the harvest of native yews for the anti-cancer drug Taxol.
