    Description

    Roads and associated vehicular traffic have the potential to significantly impact vertebrate populations. In eastern Texas we compared the densities of paved and unpaved roads within 2 and 4 km radii of timber rattlesnake (Crotalus horridus) ocations and of random points. Road networks were significantly more dense at random points than at snake localities. A similar relationship was detected within permanent stream corridors where extant populations of rattlesnakes are concentrated. Our data suggest that roads and associated vehicular tr&c have had a detrimental impact on the current distribution of C. horridus in eastern Texas.
