Road mortality is a leading cause of population decline in many freshwater turtle species, and targeted infrastructure improvements dramatically reduce deaths while maintaining connectivity.
Freshwater turtle populations are slow to recover from road mortality because females take many years to reach reproductive age. A turtle killed crossing a road represents not just one individual but potentially decades of future reproduction lost. Targeted infrastructure including purpose-built tunnels, drifting fence arrays, and modified culverts creates safe crossing corridors at high-mortality hotspots. These solutions are relatively inexpensive compared to the conservation value they protect, making them among the best-return wildlife welfare investments available.
