Use shelterwood harvest instead of clearcutting
A replicated study in 1985-1993 in temperate coniferous forest in Sweden (Hannerz & Hånell 1997) found that shelterwood harvesting increased plant diversity compared with clearcutting. Plant diversity was higher in shelterwood (Simpson index: 0.48) than in clearcut areas (0.37). Species richness, average height and total cover of plants were similar between shelterwood (species: 5.3/0.25 m2; height: 33 cm; cover: 75%) and clearcut areas (species: 4.2/0.25 m2: height: 34 cm: cover: 65%). In 1985, 2-4 clearcut (all trees removed) plots (40 × 25 m) and 4-8 shelterwood (140-200 trees/ha retained) plots (20 × 25 m) were established in each of four sites. Monitoring was undertaken in 1993 in 24-160 subplots/treatment in each site. Each subplot was 0.5 × 0.5 m.
