Summary

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 location, then counting [...]

Purpose

This layer is intended for use as an index of road risk presented to wildlife in general and to carnivores in particular. It can be combined with the equivalent layer for Idaho, which is offered separately due to inconsistent reporting of carcasses between states. In this analysis, it was used in conjunction with an identification of intersections between major roads and connectivity flowlines in order to assess congruence between connectivity value and road risk to wildlife.
