More than 10,000 tons of wild mammals are killed on Brazilian roads yearly: Assessing the impacts and conservation implications of wildlife-vehicle collisions

Nearly 9 million medium- and large-sized mammals (>1kg) could be killed on Brazilian roads each year, representing an estimated wildlife biomass of over 10,000 tons. Mortality from roads is a major threat to wildlife conservation in Brazil, and further research and mitigation is urgently needed to avoid species extinction.

Roads are a severe threat to apex predators across the globe

Apex predators play critical roles in maintaining ecosystem health, but our meta-analysis on 36 species from around the world found all are affected by roads, and particularly in Asia. Proposed road projects in the Brazilian Amazon, Africa and Nepal will affect roughly 500 protected areas and threaten what little remains of apex predator’s core habitats, driving many species closer to extinction. Better planning to avoid such areas is urgently needed.
