Abstract

We examined temporal and spatial patterns of terrestrial amphibian species abundances and individual movements in western Oregon managed headwater forest stands using artifi cial cover object (ACO) arrays. Using mark-recapture methods, we estimated the eff ects of species and seasonality on apparent survival rates and recapture probabilities. We captured, marked, and released over 300 individual salamanders during 18 site visits between 2006 and 2009. Th ese captures were dominated by three plethodontid species: Ensatina (Ensatina eschscholtzii), Western Red-backed Salamander (Plethodon vehiculum), and Dunn’s Salamander (P. dunni). We observed 64 animals move between ACOs at least once with most salamanders moving between adjacent ACOs (
