BackgroundIn 1997, the Colorado Parks and Wildlife (CPW) undertook what was to become one of North America’s most high-profile carnivore reintroductions to date. The goal of CPW’s lynx reintroduction program was to establish a self-sustaining lynx population within Colorado, where biologists felt quality lynx habitat still existed. The observations and lessons from this program – the latest in a long line of successful CPW reintroductions – may be helpful in planning future carnivore reintroductions such as wolverines in Colorado and elsewhere.
Benchmarks for success
To evaluate the near-term success of lynx reintroduction efforts, the CPW established a set of benchmarks for tracking the progress towards Colorado’s lynx population becoming self-sustaining:
- reintroduced lynx demonstrate a high rate of survival in the critical first months after release;
- released adult lynx demonstrate low mortality rates over the longer term, particularly in good habitat;
- lynx remain in good habitat at densities sufficient for breeding;
- reintroduced lynx successfully reproduce;
- lynx born in Colorado survive and also successfully reproduce (“recruitment”); and
- on balance, lynx recruitment equals or exceeds mortality over an extended period of time.
Reintroduced lynx have been monitored by the CPW for over a decade to track the population’s progress toward reaching these benchmarks. As of summer 2010, all of the CPW’s benchmarks for successful lynx reintroduction have now been met.
