Peregrine Falcons

Peregrine falcons nest on the bluffs along the Yukon & Charley Rivers. Populations have rebounded from the effects of DDT and now available space along the bluffs is potentially the limiting factor.



Wolves in Yukon-Charley Rivers are a species of concern, as they are a sign of ecosystem health. Their population is monitored each winter by aerial surveys and radio-collared individual wolves.
