The northeastern U.S. is highly exposed to climate change; in fact, the rate of change is higher than most places on earth (Karmalkar and Bradley 2017). The forests of the Northeast CASC region, and the wildlife that inhabit them, are highly vulnerable to the effects of climate change.  In particular, the boreal forests, a biome that reaches from Alaska to the Northeast, and the northern hardwoods, including sugar maple and paper birch, are expected to be intolerant of climate warming. Likewise, many of the birds, mammals, amphibians, fish, and insects that inhabit these forest ecosystems are at their southern range edges here and are considered sensitive to climate change. Furthermore, local species’ adaptive capacity is limited by habitat fragmentation, high rates of invasive species, and other stressors. There is considerable uncertainty with respect to the magnitude and direction of future changes, particularly with respect to interactions with changes in land use and land management, as well as novel interactions amongst co-occurring species. Thus, a focus on climate adaptation in northern forest ecosystems, including evaluations of the impacts of particular actions, is critical. 

Climate change-driven shifts in distribution and abundance are documented in many species. However, in order to better predict species responses, managers are seeking to understand the mechanisms that are driving these changes, including any thresholds that might soon be crossed. We leveraged the research that has already been supported by the Northeast Climate Adaptation Science Center (NE CASC) and its partners and used the latest modeling techniques combined with robust field data to examine the impact of specific climate variables, land use change, and species interactions on the future distribution and abundance of species of conservation concern. Moreover, we documented biological thresholds related to climate variability and change for critical species in the Northeastern and Midwestern U.S. Our objectives were to identify the primary drivers (e.g

Invasive species and climate change represent two of the five major global change threats to ecosystems.  An emerging initiative of the Northeast Climate Science Center aims to develop management-relevant research to improve invasive species management in the face of climate change.  Through working groups, information sharing and targeted research, this project addresses the information needs of invasive species managers in the context of climate change
