Informing Adaptation Strategies for Maintaining Landscape Connectivity for Northern Rockies Wildlife
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 ris
The Past as a Prelude to the Future: Assessing Climate Effects on Native Trout in the U.S.
Salmonids (a family of fish that includes salmon, trout, and char) are a keystone species for both aquatic and terrestrial ecosystems, and can be an early warning indicator of ecosystem health. Salmonids also have strong societal values and contribute enormously to regional economies and Native American cultures. Today, many native salmonid populations are small, highly fragmented, and isolated fr
Webinar: The Potential Influence of Changing Climate on the Persistence of Rocky Mountain Native Salmonids: What Information Will We Need to Manage for the Future?

Integrating ecological forecasting methods to improve applications for natural resource management: An invasive species example
Projecting the effects of climate change on plant and animal species distributions and abundance is critical to successful long‐term conservation and restoration efforts. There have been significant recent advances made in the areas of: (1) climate forecasts; (2) habitat niche modeling; (3) mechanistic modeling; and (4) observation techniques and networks. However, projections of biological change
Understanding Extreme Climate Events in the North Central U.S.
The climate of the North Central U.S. is driven by a combination of factors, including atmospheric circulation patterns, the region’s complex topography which extends from the High Rockies to the Great Plains, and variations in hydrology. Together, these factors determine the sustainability of the region’s ecosystems and the services that they provide communities. In order to understand the vuln
A Visualization Approach for Projecting Future Climate Distributions in North America
Conservation and natural resource managers require information about potential future climate changes for the areas they manage, in terms that are relevant for the specific biotic and environmental resources likely to be affected by climate change. We produced a suite of data sets that provide managers with climate and climate-derived data and a visualization approach that allows managers to map w
Downscaled Climate Change Modeling for the Conterminous United States (National Assessment)
This project produced long simulations (multi-decadal to multi-century in scale) of past, present, and future regional climate at a grid spacing of 50 kilometers (km) over North America and at a grid spacing of 15 km over western and eastern North America. These model runs were the first attempt to achieve coordinated, high-resolution downscaling with such wide geographic and temporal coverage. Th
Science to Inform Future Management of the Nation's Fisheries and Aquatic Habitat
Fisheries and aquatic habitats throughout the United States are in dire need of protection or restoration because human activities have resulted in severe degradation of those habitats. Further, future climatic changes will continue to affect human land-use, temperature, and water flows. Natural resource managers need to identify and prioritize habitats so that limited time and funding can be focu
