Although Central America is one of the most biologically diverse regions in the world, booming road construction is driving roadkill mortality that threatens to alter the demography, genetic diversity, and viability of wild mammalian populations. Hacienda Baru National Wildlife Refuge is located along a critical biological corridor bisected by one of the busiest highways in the country. In this case study, we explore whether well-designed wildlife crossing structures can reduce roadkill mortality of wildlife and contribute to wildlife-friendly roadways.
