Forest fragmentation creates edge environments that alter light, temperature, and moisture conditions, potentially affecting terrestrial salamanders that depend on cool and moist microhabitats. Additionally, climate change related decline in precipitation patterns is expected to further complicates forest fragmentation impacts. The Eastern Red-backed Salamander (Plethodon cinereus) is widely recognized as a bioindicator of forest ecosystem integrity because of its sensitivity to changes in their surrounding habitats . This study evaluated how forest edge distance and experimental moisture treatments influence the abundance, frequency of occurrence, and body condition of P. cinereus within the Climate Change Interaction With Forest Fragmentation (CLIFF) experiment at Harvard Forest. Weekly surveys were conducted between June and July 2026 across six experimental plots representing drying, control, and moist treatments. Each plot contained two transects (40 m each) extending from the forest edge to the interior, with six cover boards per transect. During each survey, salamander presence, abundance, occurrence, life stage, snout–vent length (SVL), total length (TL), and body mass were recorded. Data were organized and analyzed in R using generalized linear mixed models (GLMMs) to evaluate the effects of edge distance, moisture treatment, and their interaction, while body condition was assessed from the relationship between body mass and SVL. A total of 36 salamanders were detected during 648 cover board surveys, with adults representing the most frequently observed life stage. Preliminary analyses revealed a strong positive relationship between body size and body mass and suggested variation in salamander detections among moisture treatments and along the edge-to-interior gradient. These preliminary findings support the hypothesis that forest edge effect and moisture availability jointly influence P. cinereus populations and provide a foundation for understanding how forest fragmentation and climate change interact to shape salamander populations in northeastern temperate forests.
