Movement that once defined survival is being cut off.
Road networks are reshaping wildlife movement in ways that extend far beyond isolated collisions. Migration routes that once connected feeding grounds, breeding areas, and seasonal habitats are being interrupted by expanding infrastructure that animals cannot easily navigate or avoid. In many cases, the impact is not immediate but cumulative, as repeated disruptions reduce access to critical resources and limit genetic exchange between populations. Species that rely on learned or instinctive pathways face increasing pressure as those routes become fragmented or inaccessible. The result is not just displacement, but long-term population decline driven by barriers that continue to expand across landscapes animals have used for generations.
