Monitoring Small Mammal Populations in Coniferous Forest Ecosystems of Olympic National Park: Preliminary Assessment

摘要

We conducted a 3-year pilot study to evaluate the feasibility of estimating and monitoring populations of small mammals in low-elevation old-growth coniferous forests of Olympic National Park. Primary objectives of the study were to: (1) determine species present in low-elevation coniferous forests of Olympic National Park, (2) evaluate performance of closed-model population estimators of species abundance, (3) evaluate spatial and temporal variation in indices of abundance derived from constant-effort trapping grids, and (4) make recommendations for future monitoring of small mammal populations.
