Sea lion and fur seal breeding colonies are highly sensitive to human disturbance that can cause panic stampedes, crushing of pups, and mass abandonment of breeding sites.
Pinniped breeding colonies disturbed by approaching humans, boats, or drones experience panic responses where large animals rush to the water crushing pups and causing mother-pup separation. Separated pups unable to reconnect with their mothers face starvation and hypothermia. Even moderate-level repeated disturbance reduces reproductive success across entire colonies. Maintaining adequate buffer zones around breeding beaches during pupping season, restricting boat traffic, and prohibiting drone flights are welfare-critical management measures with clear evidence of effectiveness.
