“…Tevis (1952Tevis ( , 1953 showed that yellow-pine chipmunks in northern California rely heavily on hypogeous fungi. In northeastern Oregon; Maser and Maser (1987) reported that stomach contents of 135 individuals consisted of about 13 percent hypogeous fungi by volume. Beg (1969) did not report fungi in the diets of either red-tailed chipmunk or yellow-pine chipmunk in western Montana, but he examined only cheek pouch contents of live-captured individuals.…”

“…In places where these small mammals defecate they inoculate the soil with spores of mycorrhizal fungi that are essential for nutrient uptake of the trees. Thus, the small mammals essentially contribute to maintenance of the forests (Maser et al 1978a , b ;Kotter and Farentinos 1984a , b ;Maser et al 1985 ;Hayes et al 1986 ;Maser et al 1986 ;Maser and Maser 1987 ;Carey et al 1999 ). One gram of dried feces has been estimated to contain between 200 million and one billion spores (Kotter 1981a , b ).…”

“…Forests with high canopy cover may have maintained cooler and more stable microclimates, which might be important to species like Trowbridge's shrews, which have high metabolic rates and heat loss (Ingles 1965). High canopy cover was associated with greater abundances of conifer or deciduous tree seeds, which comprise significant portions of the diets of chipmunks, shrews, and deer mice (Terry 1974, Gashwiler 1979, Maser and Maser 1987. Furthermore, cooler microclimates and other conditions associated with high canopy cover like coarse woody debris accumulation may allow for higher diversity and abundance of fungi and invertebrates, which are important food sources for chipmunks and shrews, respectively (Carey and Johnson 1995).…”

Livestock grazing is common and widespread throughout North America, yet few studies have evaluated its effects on small mammals. We studied small mammals in mixed‐conifer forests and oak woodlands on the Cascade‐Siskiyou National Monument in southern Oregon, USA, to 1) evaluate small‐mammal microhabitat associations, 2) identify riparian‐associated species, and 3) test the hypothesis that grazing does not influence small mammals after accounting for microhabitat associations. We live‐trapped small mammals at 16 study sites and used logistic regression to model probability of capture on measured habitat characteristics at each trap station and to evaluate effects of grazing. Over 2 years, we trapped 1,270 individual small mammals representing 18 species. Odds of capturing western harvest mice (Reithrodontomys megalotis), dusky‐footed woodrats (Neotoma fuscipes), and long‐tailed voles (Microtus longicaudus) were lower (P < 0.05) on heavily versus lightly grazed sites. Odds of capture for deer mice (Peromyscus maniculatus) were lower (P < 0.05) on heavily versus lightly grazed sites in woodlands, but there was less difference in the odds of capture between grazing intensities in conifer forests. Odds of capturing Townsend's vole (Microtus townsendii) were lower on heavily versus lightly grazed riparian areas. Western harvest mice, long‐tailed voles, and Townsend's voles were associated with, but not obligated to, riparian areas. Deer mice were ubiquitous, but captures were also higher (P < 0.05) in riparian areas compared with uplands. Siskiyou chipmunks (Tamias siskiyou) and piñon mice (Peromyscus truei) were associated with uplands (P < 0.05) rather than riparian areas. Trowbridge's shrews (Sorex trowbridgii), Siskiyou chipmunks, and bushy‐tailed woodrats (Neotoma cinerea) were positively associated with coarse woody debris. Land managers should anticipate that small mammals associated with herbaceous or shrub cover, particularly in riparian areas, will decline when cattle remove this cover.
