The greenback cutthroat is one of last three remaining species of cutthroat trout that is native to Colorado. Their populations were decimated during the initial settling of the west, and for a period of time this species was thought to have become extinct. Later, greenback cutthroats were believed to have been rediscovered, but this proved to be case of mistaken identity. Genetic testing later provided evidence that this “old Strain” of greenback cutthroats were in fact Colorado Cutthroats, an entirely different subspecies of cutthroat trout. It wasn’t until later that a small population of true native greenback cutthroat were discovered in Bear Creek near Colorado Springs.
Since this discovery there has been a significant effort to capture the genetic pool of these true greenback cutthroats, breed them in controlled environments, and repopulate native waters with these trout. Much of this work is thanks to the Greenback Recovery working group, currently lead by Colorado TU Grassroots Coordinator, Dan Omasta. This working group is a collaborative effort including organizations such as Trout Unlimited, the Division of Fish and Wildlife, the Forest Service, and front range CTU chapters.
