Wildlife crossing structures are increasingly being planned and constructed in Colorado to mitigate the negative impacts of roads on wildlife and to reduce incidence of wildlife-vehicle collisions. Yet the few monitoring efforts deployed have not followed standardized protocols and some have only captured species presence at structures.
Several studies have been conducted at select locations (e.g., Singer et al. 2011) and/or for select species (e.g., Crooks et al. 2008). Recently, CDOT’s Southwest Region, has committed to placing camera traps at all new crossing locations in the region for 3 years.
