Biodiversity elements vulnerable to climate change in the Catskill High Peaks subecoregion (Ulster, Delaware, Sullivan, and Greene Counties, New York State).

Climate change is expected to affect biodiversity elements in the Catskill High Peaks subecoregion of New York State with effects that are difficult to predict. The present communication details the species and communities of greatest conservation concern in this portion of the state and makes recommendations for monitoring the most pressing climate change-biodiversity vulnerabilities. Specifically, we present sites for monitoring representative old-growth and successional stands of red spruce/balsam fir and northern hardwood matrix forests, cliff communities, ice cave talus communities, and both minerotrophic inland poor fen and ombrotrophic perched peatlands. The proposed monitoring protocols vary among the various sites, but all are quantitative and are designed to document patterns of change.
