Despite their dominance these forests, little is known about selection home ranges. We radiotracked 23 3 mature, coniferous forest stands southern Cascades during 1994 1995 estimated range size, movements, habitat associations. Males had larger ranges than females males moved farther each evening females. Females were most active 2 periods: shortly after dusk before dawn. all night. Core areas for characterized by deep organic soil layers volumes decayed logs. Results underscore importance matter coarse woody debris on floor maintaining populations western-red-backed voles.
