Urban planning decisions profoundly affect wildlife welfare through habitat creation or destruction, road design, lighting, and infrastructure that can support or harm urban animal populations.
Urban planning determines the welfare of the millions of wild animals that live in cities alongside humans. Road design affects roadkill rates. Lighting affects nocturnal species. Building materials determine window collision rates. Green space connectivity enables movement and foraging. Cities that plan for wildlife create environments where urban animals can find food, shelter, and movement routes — reducing the chronic stress of habitat-poor urban environments.
