Summary
The U.S. Northern Rocky Mountains support a large number of native wildlife species, and survival of these populations depends on connected landscapes to support current migration and dispersal, as well as future shifts in species’ ranges. However, habitat fragmentation and loss threaten these connections.
Land and wildlife managers across the U.S. are faced with decisions focused on reducing risks, like those from habitat fragmentation, to wildlife, ecosystems, and landscapes. Establishing connections between natural landscapes is a frequently recommended strategy for these managers to help wildlife adapt to changing conditions.
Working in partnership with state and federal resource managers and private land trusts, this project sought to 1) understand how future climate change may alter habitat composition of landscapes that are expected to serve as important connections for wildlife, 2) understand how wildlife species of concern are expected to respond to changing conditions, 3) develop strategies to help stakeholders manage public and private lands in ways that allow wildlife to continue to move in response to changing conditions, and 4) explore how well existing management plans and conservation efforts are expected to support crucial connections for wildlife under climate change.

Purpose
Establishing connections among natural landscapes is the most frequently recommended strategy for adapting management of natural resources in response to climate change. The U.S. Northern Rockies still support a full suite of native wildlife, and survival of these populations depends on connected landscapes. Connected landscapes support current migration and dispersal as well as future shifts in species ranges that will be necessary due to our changing climate. Working in partnership with state and federal resource managers and private land trusts, we seek to 1) understand how future climate change may alter habitat composition of landscapes expected to serve as important connections for wildlife, 2) understand how wildlife species of concern are expected to respond to these changes, 3) develop climate-smart strategies to help stakeholders manage public and private lands in ways that allow wildlife to continue to move in response to changing conditions, and 4) explore how well existing management plans and conservation efforts are expected to support crucial connections for wildlife under climate change. Ultimately, this project aims to ensure that the iconic landscapes of the Northern Rockies and the wildlife they support endure in a changing landscape for the benefit of future generations.

Technical Summary
value
The U.S. Northern Rockies ecosystem and its wildlife are increasingly threatened by habitat loss and fragmentation, and these effects are expected to be amplified by climate change. Enhancing landscape connectivity is the most frequently recommended climate adaptation strategy. In cooperation with the Great Northern LCC and in partnership with state and federal land and wildlife managers, private land trust partnership staff, and large landscape conservation practitioners, the objectives of this project are to a) assess the vulnerability of landscapes that are crucial for wildlife connectivity in the U.S. Northern Rockies to climate change, and b) to develop decision-relevant adaptation strategies for climate-based management and conservation action in these landscapes. We propose to: 1) use projected future biome distributions to estimate ecologically relevant exposure of connectivity landscapes to climate change, 2) score sensitivity of focal wildlife species to biome transitions and quantify adaptive capacity in the context of fragmentation due to human land use, 3) develop adaptation strategies for priority landscapes that are robust to uncertainty in future conditions and ecological responses, and 4) conduct a gap analysis of the extent to which existing management plans and conservation efforts support future connectivity needs under a changing climate. These efforts will culminate in a report, spatial data products, and map-based decision support tool that are tailored to the needs of resource managers and conservation practitioners and offered freely via ScienceBase, Data Basin, and partners’ data portals.
