Wildlife corridors enable safe movement between habitat fragments, reducing road mortality and enabling natural behaviours that are essential for individual animal welfare.
Wildlife corridors address welfare needs at multiple scales: individually, they reduce the probability of death or injury from road collisions; at population level, they prevent the genetic isolation that leads to inbreeding depression and reduced disease resistance. The design of corridors determines their effectiveness — species-specific requirements for width, vegetation cover, substrate, and proximity to human disturbance are critical. A corridor too narrow, too bright, or too close to human activity may be avoided entirely. Investment in effective corridor infrastructure requires ecological surveys to identify movement routes, engineering solutions appropriate to the landscape, and post-installation monitoring to verify use and welfare outcomes. Public and political support for corridor investment is growing as evidence of effectiveness accumulates.
