This layer provides information on putative winter corridors facilitating dispersal from northern populations to patches capable of supporting Canada lynx in the Northern Rocky Mountains. These results combine resource selection, step selection, and least-cost path models to define movement corridors for lynx in the Northern Rocky Mountains. The illustrated corridors were created by using a one-mile buffer around the putative winter corridors facilitating dispersal from northern populations to patches capable of supporting Canada lynx in the Northern Rocky Mountains

This dataset was created by overlaying connectivity model outputs for grizzly bear, black bear, lynx, wolverine, forest specialist species, and forest biome dwellers where they intersect the region’s major roads. It was used in conjunction with future traffic volume projections to identify priority sites for mitigating road impacts on wildlife. This project investigated the potential impacts of future housing development on traffic to determine where increased traffic from housing development will impact habitat connectivity for large carnivores. The focus of this study was Flathead and Lincoln counties in northwestern Montana. The main goal was to maintain wildlife habitat connectivity across transportation corridors...

These case study sites are detailed in the report accompanying this data layer. The case studies are intended to serve as examples of how some of the opportunities for diverse stakeholders to engage in the process of mitigating road impacts on wildlife that are described in the report might be applied on the ground, as well as other considerations that come into play in selecting sites for possible mitigation and designing mitigation solutions for those sites. Through these case studies, we illustrate potential opportunities for mitigation and partner engagement for each of the four alternative priority sets identified in this study.Wildlife carcasses recorded by Montana Department of Transportation, Idaho Department...

These layers provides information on putative summer and winter corridors facilitating dispersal from northern populations to patches capable of supporting Canada lynx in the Northern Rocky Mountains. These results combine resource selection, step selection, and least-cost path models to define movement corridors for lynx in the Northern Rocky Mountains. The polygon corridors were created by using a one-mile buffer around the putative winter corridors facilitating dispersal from northern populations to patches capable of supporting Canada lynx in the Northern Rocky Mountains

Wildlife carcasses recorded by Montana Department of Transportation, Idaho Department of Fish & Game, and U.S. Fish & Wildlife Service were aggregated to the nearest mile marker for major roads of the U.S. Northern Rockies. WGA connectivity flowlines were intersected with the road network and attributed to the nearest mile marker, along with their connectivity ranking, which indicates their expected relative importance to maintaining westwide connectivity. Values for potential risk factors, including average annual daily traffic (AADT), functional class, number of lanes, road surface width, landscape condition of surrounding habitat, ruggedness of surrounding landscape, and topographic position relative to surrounding...

We assessed the vulnerability of ecological processes and vegetation to climate change in the US Northern Rocky Mountains with a focus on the Greater Yellowstone Ecosystem. We found that climate has warmed substantially since 1900 while precipitation has increased. An index of aridity decreased until about 1980 and then increased slightly. Projected future climate indicates warming of about 3-7 degrees C by 2100 and a substantial increase in aridity, depending on climate scenario. Snow pack, soil moisture, runoff, and primary productivity are projected to decrease dramatically in summer under future climate scenarios, with snow pack and runoff declining annually. Habitat suitability for the four subalpine tree species...

Wildland fire is a key ecosystem process that shapes the landscape of Western United States. Changes in fire regimes can therefore have profound impact on ecosystem functions and services, including carbon cycling, habitat conditions, and biodiversity. This study examined fire regime changes in the Northern Rocky Mountain region using a landscape succession model (LANDSUMv4). The objective is to report a new method to develop fire regime condition class (FRCC) maps by comparing historical reference conditions of fire regimes – simulated using historical fire record and the LANDSUMv4 model – with current fire regimes developed using 27 years remote sensing fire product and LANDSUMv4. Results of this study indicate...

This decision support tool provides spatially explicit information pertaining to modeled wildlife connectivity value across major roads, total wildlife mortality counts along major roads, carnivore mortality counts along major roads, the extent to which wildlife connectivity value and road mortality align, and potential priority sites for mitigation of road impacts on wildlife from diverse stakeholder perspectives. In the report accompanying this map document, we also discuss potential opportunities for diverse stakeholders (including departments of transportation, state and federal land managers, land trusts, citizen groups, and conservation organizations with a variety of missions) to engage in and contribute...

Carnivore carcasses recorded by Montana Department of Transportation, Idaho Department of Fish & Game, and U.S. Fish & Wildlife Service were aggregated to the nearest mile marker for major roads of the U.S. Northern Rockies. Note that wildlife carcass collection and reporting protocols and frequency differ between states and among maintenance sections within states. Carcass presence should therefore be used only to explore general patterns and not for statistical inference.

This layer represents the mile markers along the major road network of the U.S. Northern Rockies. It was created by merging Montana Department of Transportation "on-system" routes with Idaho Transportation Department "state highway system" routes, creating consistent attribute fields, then clipping to the U.S. Northern Rockies study area boundary.
