Urban green corridors connecting parks, gardens and open spaces enable wildlife movement through cities - their design significantly affects which species can use them and their welfare outcomes.
Urban wildlife corridor welfare benefits operate primarily at the population level by reducing fragmentation that isolates small groups and prevents gene flow. Individual welfare benefits include access to more diverse food resources, mate availability and reduced intraspecific competition within isolated patches. Road crossing points within corridors are welfare risks where animals must cross high-traffic roads - underpasses and green bridges address this. Garden-level connectivity through hedgehog highways and diverse planting enables local movement within residential areas. Corridor planning that integrates welfare thinking alongside biodiversity metrics creates more effective wildlife-supporting urban environments.
