Study finds northeastern US mountain streams may serve as refugia for endangered wood turtle

Climate change is driving many species toward cooler habitats, and high‑elevation ecosystems are emerging as critical refuges for biodiversity. A recent study from the Great Hollow Nature Preserve & Ecological Research Center in New Fairfield, Connecticut, examined the potential of streams in the Catskill Mountains and other northeastern U.S. ranges to serve as safe havens for the region’s most imperiled freshwater turtle, the wood turtle (Glyptemys insculpta). The research found that cooler, well‑oxygenated mountain streams could maintain suitable temperature and moisture conditions for the species even as low‑land habitats become increasingly inhospitable.

The study highlights that wood turtles, which rely on specific riparian environments for nesting and foraging, face heightened risks from rising temperatures, altered precipitation patterns, and habitat fragmentation. By modeling projected climate scenarios, the researchers identified several high‑elevation stream corridors that are likely to remain within the turtles’ thermal tolerance limits through the next century. These corridors also coincide with areas of relatively intact forest cover, reducing the threat of human disturbance and providing additional ecological benefits for other cold‑water species.

The findings underscore the importance of protecting and managing high‑elevation stream habitats as part of a broader conservation strategy for the wood turtle. Conservation agencies and land managers may use this information to prioritize restoration efforts, monitor water quality, and implement protective measures in these mountain refugia. Maintaining these critical habitats could be key to ensuring the long‑term survival of the wood turtle in a warming climate.
