  1. Log/remove trees within forests: effects on mature trees

    A replicated, controlled study in 1984-1996 in temperate coniferous forest in Finland (Lähde, Eskelinen & Väänänen 2002) found that cutting treatments decreased the wood volume but not the number of trees. Tree volume (m3/ha) was higher in uncut (248) than in six cutting treatments (32-153). However, there was no difference between treatments for the number of trees/ha (uncut: 2,226; cutting treatments: 1,684-2,669) or seedlings/ha (uncut: 6,156; cutting treatments: 6,109-15,625). Four replicates of seven treatment units (1-3 ha) were established in 1984: uncut; Norway spruce Picea abies shelterwood (330 spruce trees left); Scots pine Pinus sylvestris shelterwood (220 pine trees left); mixed shelterwood (450 trees left); single-tree selection; group selection (~25 m openings); diameter cutting (>25 cm DBH). Volume and number of trees (>1.3 m tall) were monitored in 1996 in one 40 × 40 m plot in each treatment unit. Seedlings (0.1-1.3 m tall) were monitored in 1991 in 16 subplots (10 m2) within each plot.
