Use shelterwood harvest instead of clearcutting Forest Conservation

A replicated, controlled study in 1974-1992 in temperate coniferous forest in Montana, USA (Shearer & Schmidt 1999) found that shelterwood harvesting increased the density of conifers compared with clearcutting. Density (trees/ha) of conifers >30 cm tall (shelterwood: 19,895; clearcut: 6,834) and total conifer density (shelterwood: 31,389; clearcut: 8,741) were the highest in shelterwood. Three blocks of each treatment, shelterwood and clearcutting, were duplicated in two sites in 1974. Data were collected in 1992 in 80 plots (0.004 ha) in each treatment block.
