Urban construction and infrastructure development displaces, injures, and kills urban wildlife through habitat destruction, noise, vibration, light, and chemical contamination.
Urban construction creates acute and cumulative welfare harm for urban wildlife that is often legally permitted and rarely monitored. Birds nesting in trees cleared for development, foxes with cubs displaced from denning sites, and hedgehogs trapped in construction exclusion netting are common welfare incidents. Best practice requires seasonal restrictions on vegetation clearance during breeding season, wildlife-friendly netting specifications, ecological clerk of works attendance during sensitive operations, and mitigation planting and habitat creation as conditions of planning permission. These protections require regulatory specification and enforcement to be reliably implemented.
