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.
