Log/remove trees within forests: effects on understory plants
A replicated, controlled study in 1951-1998 in coniferous montane and subalpine forest in Wyoming, USA (Selmants & Knight 2003) found that harvesting increased species richness but not cover of understory plants. The number of species/forest unit was higher in harvested than control plots in both montane (harvested: 26; unharvested: 19) and subalpine forest units (harvested: 32; unharvested: 12). Total cover of understory plants was similar between treatments in both montane (harvested: 25%; unharvested: 23%) and subalpine units (harvested: 58%; control: 55%). Data were collected in 1997-1998 using 50 frames (50 × 100 cm) at each of 30 harvested (in 1951-1969) and 24 unharvested forest units (< 0.5 ha).
