Small mammal communities of streamside management zones in intensively managed pine forests of Arkansas

摘要: Abstract Streamside management zones (SMZs), composed primarily of hardwoods in the southeastern United States, provide habitat diversity within intensively managed pine (Pinus spp.) plantations. However, effects SMZ width and adjacent plantation structure on riparian wildlife communities are poorly understood. Therefore, during 1990–1995, we examined small mammal 5 classes (1–20 to >100 m) embedded three types plantations (young, open canopy; closed thinned) natural stands Ouachita Mountains Arkansas, USA. We captured mammals for 10 consecutive days each February using four six traplines consisting nine trap stations with snap traps at station. estimated relative abundance [catch-per-unit-effort (CPUE)], species richness, diversity, evenness all captures just along stream course. Within SMZ/plantation settings stands, 1701 11 114,285 trapnights. Golden mice (Ochrotomys nuttalli), southern short-tailed shrews (Blarina carolinensis), Peromyscus spp. comprised 88% captures. Our study suggests that narrow (≤20 m wide) SMZs forests tend have higher richness than wider SMZs. Additionally, CPUE was greater young, canopy thinned versus Plantation appears influence community more width. Shortening amount time spend conditions would likely improve existing landscapes. South designed meet voluntary water quality standards sufficient conservation.
