Habitat fragmentation caused by roads, development, and agriculture creates welfare harm for wildlife through increased movement costs, reduced access to resources, and elevated conflict with humans and vehicles.
Habitat fragmentation creates chronic welfare harm through a mechanism less visible than direct killing: it forces animals to bear increased costs in navigation, predator avoidance, and resource finding. An elk that must cross a busy highway to reach seasonal range bears welfare costs of stress, injury risk, and energy expenditure that population census data cannot capture. Wildlife corridors reduce these costs by enabling safer, more direct movement between habitat patches. The effectiveness of corridor infrastructure is well-documented, making this one of the highest-evidence welfare interventions in conservation. Integrating corridor planning into land use decisions at regional scale is a welfare and conservation priority.
