Lessons from Success

The same playbook shows up across very different species, though some fights are far from over. Decades of captive breeding and release pulled the California condor back from the edge, yet the birds keep ingesting lead fragments from ammunition in carcasses — a threat that still isn't fully resolved, so the wild flock depends on ongoing human support.

The Arabian oryx, reintroduced in 1982, needed decades of continued protection before wild herds could sustain themselves. And the mountain gorilla doubled in number partly because nearby communities earned income from conservation tourism, giving them a reason to protect the animals rather than poach them.
