Abstract: The Northeastern Research Station's Forest Inventory and Analysis (NE-FIA) unit is conducting the Pennsylvania Regeneration Study (PRS) to evaluate composition and abundance of tree seedlings and associated vegetation. Sampling methods for the PRS were tested and developed in a pilot study to determine the appropriate number of 2-m microplots needed to capture variability in seedling abundance. The findings resulted in a decision to use one 2-m fixed-radius microplot per 7.3-m fixed-radius subplot of the NE-FIA design. Preliminary results indicate that one-half to two-thirds of the region's forests would require remedial treatment if preferred species are the management objective.
