Use selective harvesting instead of clearcutting Terrestrial Mammal Conservation

A replicated, controlled study in 1997–1998 of a forest in Maine, USA (Fuller et al. 2004) found more small mammals in selectively harvested forest stands than fully harvested, regenerating stands. Annual average catches were higher in partially harvested than fully harvested stands for the three most abundant species; red-backed vole Clethrionomys gapperi (partially harvested: 12.4–22.1; fully harvested: 2.5–5.0 voles/grid), deer mouse Peromyscus maniculatus (partially harvested: 4.9–12.5; fully harvested: 0–2.5 mice/grid) and short-tailed shrew Blarina brevicauda (partially harvested: 4.3–5.0; fully harvested: 0–3.0 shrews/grid). These comparisons were not tested for statistical significance. Seven stands were selectively harvested between 1992 and 1995, with 52–59% of basal tree area removed and 13 m2/ha basal area remaining. Two forest stands were clearcut between 1974 and 1984 and treated with the herbicide, glyphosate, 3–8 years post-harvest. Small mammals were surveyed in live trap grids, between 22 June and 28 July 1997 and between 21 June and 31 July 1998.
