Log/remove trees within forests: effects on understory plants
A replicated, randomized, controlled study in 1991-1993 in temperate coniferous forest in Oregon USA (Bates, Miller & Svejcar 2000) found that cutting western juniper Juniperus occidentalis trees increased total biomass and cover of understory perennial plants. The total biomass of understory perennial plants (cut: 329 kg/ha; uncut: 38 kg/ha) and their cover (cut: 4.3-4.8%; uncut: 1.4-1.5%) was higher in cut plots. In 1993, total biomass was sampled at 3 m intervals with 1 m2 quadrats along two 45 m transects. Cover of perennial plants was measured along five 30.5 m line transects in each plot of eight pairs of cut (all juniper trees were cut down in 1991) and uncut 0.4 ha plots.
