Pine thinning caused highly significant increases in understory vegetation. After eight growing seasons, total understory yield increments ranged from 75 lb/acre on the unthinned plots to 417 lb under 26-foot pine spacing. The increase comprised 51% grasses, 37% forbs, and 12% shrubs. When pine canopy exceeded about 45%, forbs produced more than grasses; below 45%, grasses were superior producers. Shrubs were the least productive at all levels.Type
