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 connectivity areas correspond to the Version 3 core areas in Wyoming. They are closely linked to the core areas but are NOT core.

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...

Greater sage-grouse population components devrived using an 18-km maximum connection distance. Analysis was conducted using the CONEFOR SENSINODE 2.2 software package and this dataset was developed from lek data obtained from the state wildlife agencies. Components containing < 5 leks have been removed in order to protect the location of single or small groups of leks.

This dataset is the output of a python script/ArcGIS model that identifes dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike. Areas continuous with eachother were considered part of the same dike. Post processing occured. Users examined the data output, comparing the proposed dike locations to aerial imagery, flowline data, and the DEM. Dikes that appeared to be false positives were deleted from the data set.

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...

In 2007, American Wildlands (Bozeman, MT) initiated a "Priority Linkage Assessment" (PLA) through which we have identified, cataloged and prioritized the threats to, and opportunities for, maintaining connectivity in the U.S. Northern Rockies (Montana, Idaho and Wyoming). The process involved interviewing wildlife movement and connectivity experts from state and federal agencies, and independent biologists with proven knowledge of wide-ranging wildlife. The experts were asked to use their professional and personal experience in the field (knowledge of related scientific studies and their own field research) to identify important areas of wildlife connectivity ("linkages" - defined as as a specific area through which...

This represents the flowline network in Western Lale Erie Restoration Assessment (WLERA). It is attributed with the number of disconnections between the reach and the connecting river system. These data will help identify the condition of hydrologic separation between potential restoration areas and the connecting river system. Low numbers represent fewer disconnections such as culverts between the reach and the rivers requiring no flow network modification to restore the area.

These data will help identify the condition of hydrologic separation between potential restoration areas and the connecting river system. Low numbers represent fewer disconnections such as culverts between the reach and the rivers requiring no flow network modification to restore the area.

This layer provides information on putative summer 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.

River valley boundary extents were generated for select large river floodplains of the Upper Midwest, United States. These polygons were delineated using a method that incorporated interpolating a water surface elevation that completely over-topped water-control structures within the valley such as levees, flood walls, and roadways. The intersection of this derived water surface and land elevation at the outermost edge of the floodplain was used to delineate the approximate extent of the river valley boundary. We used best professional judgment to approximate this water surface elevation. River transects were generated at 1-mile increments across select large river floodplains of the Upper Midwest, United States....

This dataset is part of a multi-scale assessment and classification for segments of 15 rivers of the Upper Midwest United States that meet various criteria for largeness. All rivers are tributary to the Mississippi River system. The 11,600 kilometers (km) that qualified as large were parsed into 10-kilometer-long segments and classified by major alterations (free-flowing, navigation pools, storage reservoir). The dataset also includes a statistically based, component classification based on the 10-km segments. Cluster analysis of hydrologic variables from 66 streamflow gaging stations yielded 5 clusters calculated from 5 ecohydrological metrics related to lateral connectivity with the floodplain. A separate cluster...

A GIS-based analysis was used to model habitat connectivity in the three Okanagan Regional Districts in British Columbia: the North Okanagan Regional District, the Central Okanagan Regional District and the Regional District of Okanagan-Similkameen. This model integrated a series of parameters to identify connected and potentially fragmented habitats. The model was not specific to a particular species. The goal was to identify portions of the landscape offering a higher opportunity for wildlife movement at a regional scale. The following parameters were used to model connectivity corridors: Elevation – Lower elevations (i.e., the valley) receive higher scores; Slope – Steep slopes receive lower scores; Terrain Ruggedness...

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.
