found: Wikipedia, Dec. 21, 2006(under Silviculture: Common Silvicultural Regeneration Methods: Shelterwood - The removal of trees in a series of cuts to establish new forest reproduction under the shelter of the retained seed trees. The main difference between the shelterwood and seed tree methods is that the residual trees in a shelterwood alter the environmental conditions, such as sunlight, temperature, and moisture, for tree seedling growth, while the few retained trees in a seed tree method do not. Commonly the shelterwood method involves three cuts: Preparatory cut; Establishment cut; Removal cut)
