In 2017, the Northern Research Station is celebrating 50 years of silviculture research in Allegheny Hardwood and mixed oak forests in Pennsylvania. The comprehensive suite of studies, including work on basic silviculture; forest harvesting practices; deer-forest interactions; herbicide, fencing, and fertilization; natural and human disturbances; and prescribed fire has always had one overall goal: to promote regeneration and sustainability of forest resources. Results have been rolled in to SILVAH (SILviculture of Allegheny Hardwoods, expanded to mixed oak forests in 2002). SILVAH is a decision-support computer program, a training program, and a community of practice that brings scientists and land managers together to apply research results on the ground.

Since training sessions began in 1977, we’ve hosted nearly 2,500 professionals from 30 different states and 4 countries. Our attendees include consultants, forest industry, conservancies, educators, nonprofits, and managers from every level of government, from local to federal. Learn more about our SILVAH partnerships.
