Colorado’s natural balance—and how wolves fit in. Our project, launched nearly six months ago, rests on one primary objective: bringing the gray wolf back to Colorado. Before we explain how we want to reintroduce the gray wolf to Colorado, let’s explore the why. Wolves have been missing from Colorado’s landscape for over half a century, since humans forced them out in the 1940s. Colorado was their historic home but after decades of human activities, like hunting and trapping, they have essentially disappeared from the wild. For years, they roamed the Rockies and kept our balance in check and now... they're missing.
