 Spatially explicit modeling of overstory manipulations in young forests: Effects on stand structure and lightDouglas G. Sprugel, Katherine G. Rascher, Rolf Gersonde, Martin Dovčiak, James A. Lutz and Charles B. Halpern Ecological Modelling, 2009, vol. 220, issue 24, 3565-3575 Abstract: Young forests can be manipulated in diverse ways to enhance their ecological values. We used stem maps from two dense, second-growth stands in western Washington and a spatially explicit light model (tRAYci) to simulate effects of five silvicultural manipulations on diameter distribution, species composition, spatial patterning, and light availability. Each treatment removed 30% of the basal area, but differed in how trees were selected for removal. Three primary treatments were thin from below (removing the smallest trees), random thin (removing trees randomly), and gap creation (removing all trees in circles ∼1 tree height in diameter). Two additional treatments combined elements of these approaches: random ecological thin (a mixture of thin from below and random thin) and structured ecological thin (a mixture of thin from below and gap creation).
