This layer represents 5-year relative counts of wildlife carcasses collected by Montana Department of Transportation (MDT) maintenance personnel or U.S. Fish & Wildlife Service Grizzly Bear Recovery Team personnel on or adjacent to on-system (major) routes from 2008 to 2012. To obtain relative counts, the 5-year total counts per mile, which included all wildlife species observed, were divided by the maximum observed calue (98) to give a relative 0-1 risk score. Total counts, which include all wildlife species observed, along with carnivore counts, which include only black bears, grizzly bears, mountain lions, and wolves, are provided. Counts were derived by identifying the nearest mile marker to each carcass point...
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...

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...

Numerous wind energy projects have been constructed in the central and southern Great Plains, USA, the main wintering area for midcontinent Sandhill Cranes (Grus canadensis). We assessed exposure of wintering Sandhill Cranes to the current distribution of wind towers in the central and southern Great Plains by estimating overlap using location data from platform transmitting terminals (PTT) collected during winters 1998–2004. Because 90% of wind towers in the region were installed 2004–2013, comparing an established distribution of wind towers (as of January 2014) with pre-construction crane (1998-2004) distribution provides an initial assessment of the midcontinent population’s exposure. Distributions of cranes...

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.

This layer represents 5-year relative counts of wildlife carcasses collected by Idaho Transportation Department (ITD) personnel (2008-2012) or reported by the general public (2012) on or adjacent to state highway system (major) routes. To obtain relative counts, the 5-year total counts per mile, which included all wildlife species observed, were divided by the maximum observed calue (98) to give a relative 0-1 risk score. Total counts, which include all wildlife species observed, along with carnivore counts, which include only black bears, grizzly bears, mountain lions, and wolves, are provided. Counts were derived by identifying the nearest mile marker to each carcass point location, then counting the frequency...
