DescriptionSelection systems are used to manage multi-cohort forest stands by removing individual and/or groups of trees to create 0.01- to 1.0-ha openings in the canopy. Inherent in the selection system are the dual roles of tending the residual trees and regenerating a new cohort of tree seedlings. Research of silvicultural selection systems has historically focused on the ability to maintain an appropriate residual stand structure (number of trees per cohort) in perpetuity. However, few studies have specifically addressed the regeneration phase raising questions about controlling species composition and development within the new cohort. The goal of this research was to determine if 1) the size of a forest gap, 2) the duration of daylight on areas within the gap, and 3) the presence or absence of leaf litter on the forest floor affected tree species recruitment and growth.
