Calgary Zoo's Centre for Conservation Research (CCR) defines reintroduction as an attempt to establish a species in an area of its historical range, where it has reached critically low numbers or has become locally extinct.

Scientists project that 50% of species known today could disappear by the end of the century. However, there is still hope if such trends can be reversed through the restoration of endangered species and ecosystems. Reintroductions of imperiled species into the wild are becoming widespread and are growing in importance. As our experts learn more about how these projects work best, through scientific approaches, the success of these reintroduction programs will continue to improve.
