Abstract
Because nearly 90 percent of the timber in southeast Alaska occurs in uneven-aged, climax or near-climax stands, plots for a soil-site index study were restricted to even-aged stands originally developed after logging, blowdown, or wildfire. On an extensive group of freely drained soils, stands developing after logging or wildfire indicate site index 152, whereas those developing after blow-down indicate site index 126. Accordingly a site index based on stands developed after blowdown underestimates the productivity of the soil after logging.
