Abstract

The federally threatened Cheat Mountain salamander (Plethodon nettingi; hereafter CMS) is known to occur in approximately 70 small, scattered populations in the Allegheny Mountains of eastern West Virginia, USA. Current conservation and management efforts on federal, state, and private lands involving CMS largely rely on small scale, largely descriptive studies of habitat associations from a few sample sites. To address the critical need for quantitative data, we used an information-theoretic approach to elucidate site-level habitat relationships of CMS relative to a suite of biotic and abiotic habitat variables measured across the species' range. We collected data on 18 explanatory habitat variables at CMS-occupied (n = 67) and random (n = 37) sites in the summer of 2006 and examined CMS habitat relationships using a priori, logistic regression models with information-theoretic model selection.
