Abstract
Virginia pine (
Pinus virginiana Mill.) normally develops such dense stands on suitable sites, as in old fields, that thinning would seem to be a good silvicultural practice. Seedling stands may have 10,000 or more stems per acre, and stands 20 years old may still contain 2,000 trees. Even though rapid differentiation of crowns occurs in this intolerant species, resulting in early suppression of many stems and much mortality, thinning still might be expected to favor the development of greater volumes or more valuable products.
