In 2015 we conducted biweekly roadkill surveys from Richlands, VA to Wise, Va along Rt. 19 and Rt. 58. We observed 1837 roadkills from 65 species. We traveled a total of 15,022 km. We observed 1415 mammals, 188 birds, 122 domestic animals, and 105 reptiles with 9.7 roadkills per 100 km on the Coalfields Route and 15.0 roadkills per 100 km on the Ridge and Valley Route.
Several species of conservation concern were observed as roadkill. According to the Virginia Wildlife Action Plan, Tier I – Critical Conservation Need: yellow-bellied sapsucker (1), Tier III – High Conservation Need: eastern box turtle (43), Tier IV – Moderate Conservation Need: gray catbird (5), eastern towhee (4), brown thrasher (2), eastern meadowlark (2), chimney swift (1), eastern kingbird (1), eastern wood-pewee (1), yellow-throated vireo (1).
The bulk of the roadkills were meso-mammals including 408 Virginia opossums, 272 raccoons, 161 woodchucks, 127 eastern cottontails, 99 domestic cats, 98 stripped skunks. We also observed 79 northern gray squirrels, 58 fox squirrels, 53 white-tailed deer, 43 eastern box turtles, 27 eastern screech owls, and 24 snapping turtles.
Using the Virginia Department of Game and Inland Fisheries Information Service, of the 24 species of mammals over 100 grams that occur in our area, we detected 83% with no detection of mammals under 100 grams. For snakes and turtles we observed 22% of the 18 species over 100 grams with no detection of reptiles under 100 grams.
For birds, we detected 26% of the 68 species over 100 grams and 15% of the 134 species under 100 grams. We have to conclude that roads have a huge negative impact on wildlife in Southwest Virginia.
