The three main tracts of the Harvard Forest (3000 acres) in Petersham MA have been sampled every 10-30 years since 1907. Though methods have varied, each survey has involved mapping forest stands followed by intensive sampling. This inventory was completed in 1986-1993.

Stands were identified using color infared maps taken in fall 1985 for the Massachusetts Department of Environmental Management. Stand boundaries were verified on the ground. A minimum of three randomly located, variable radius, permanent plots were established in each stand. Each plot was measured using a standard forestry prism.
