Dr. James D. Arney brings over fifty years of forest biometrics industrial experience touching every aspect of inventory design, growth & yield, and harvest planning in six western States and three Canadian Provinces. He has designed in-place inventory systems, calibrated yield models for over twenty (20) tree species, developed site index curves, taper models, managed GIS systems and staff, developed hydrographic, soil and wildlife databases and prepared and presented sustained yield plans for public and private organizations through the western North America. He has developed silvicultural regimes and forest management plans for almost every major species and forest type found in the American Northwest.
Dr. Arney is the only forest biometrician who has designed and built four separate and unique computerized forest growth models (PhD. Dissertation distant-dependent whole tree (1969), USFS-Weyerhaeuser distant-dependent (1975), SPS distant-independent (1981), and FPS distant-dependent (1995)). Both SPS and FPS have been distributed world-wide and represent the most-used, integrated forest management tool set for forest inventory and silvicultural planning on “working forests” in the western United States.
