Describes the stochastic model FOREGEN that simulates regeneration in openings in northern hardwood stands that range in size from clearcuts of 2,000 by 2,000 feet to single-tree openings of 25 by 25 feet. The model incorporates the effects of seed development, dispersal, germination, seedbed conditions, advanced regeneration, and weather. Users can specify options on stand age, species composition, size of opening, harvesting in winter vs. summer, mechanical scarification, seed trees, advanced regeneration, and stump treatment for red maple. The output is percent species composition of the regeneration 3 years after harvest.
