Wolves in the Southern Rockies

Places for wolves in the Southern Rockies, © Defenders of WildlifeWolves from the north and south historically met, interbred and thrived in the Southern Rockies.

Today, appropriate and suitable wolf habitat and prey still abound in this region that includes southern Wyoming, Utah, Colorado, northern New Mexico and Arizona. 

The Potential 

Colorado alone is home to almost 300,000 elk, twice as many as any other western state (Colorado Parks and Wildlife 2012; Bishop 2012). According to a 2006 study, Colorado could host nearly 1,000 wolves (Carroll et al. 2006). And public support for wolves is strong in the state. A statewide survey commissioned by the U.S. Fish and Wildlife Service in 1994 found that a majority of residents (71 percent) favored wolf reintroduction in the state (Manfredo et al 1994; Pate et al 1996). A 2013 Defenders of Wildlife poll of Coloradans showed 72 percent in favor of protecting wolves that cross into the state from other areas and 70 percent supportive of restoring wolves in Colorado wilderness areas if they do not naturally recolonize the state (Peak Campaigns 2013). The National Park Service considered reintroducing wolves to Rocky Mountain National Park to control an overabundance of elk, but in 2008 ultimately decided to rely on sharpshooters instead.

A particularly promising area for wolves in the Southern Rockies is media executive Ted Turner’s Vermejo Ranch, which straddles the Colorado-New Mexico border and nearby Carson National Forest. Turner, a long-time supporter of restoring native biodiversity—wolves included—to his lands, exemplifies the potential of private landowners to contribute to wolf restoration. His interest also underscores the need to develop mechanisms at state and federal levels to encourage more private participation in wolf conservation and recovery efforts.

Northeast Utah is important as a corridor for connecting wolf populations from the northern to the central Rockies, al-lowing wolves to expand their range south and continue to fulfill their role in enhancing the ecological integrity of the landscape. 

The Challenges

The Southern Rockies region is difficult for wolves to recolonize on their own. Wyoming has removed all protections for wolves outside of its northwest corner. This means wolves can be eradicated again from most of the state, which severely limits any chance of wolf dispersal from the north into Utah and Colorado. Even if wolves do overcome these obstacles, Utah’s anti-wolf laws and policies do not bode well for balanced management of wolves arriving from either Wyoming or the Grand Canyon ecoregion, if wolves lose federal protections throughout the state. 

Unfortunately, no plans to restore wolves in the Southern Rockies are currently on the table. But if Wyoming, Utah and Colorado residents who welcome wolves make their voices heard, wolf policies and plans can change for the better.

The red wolf (currently recognized as a different species than the gray wolf) once ranged as far north as Pennsylvania and as far west as central Texas. Because of its wide distribution, the red wolf played an important role in a variety of ecosystems, from pocosin lowlands to forested mountains.

Gray wolf recovery in the Great Lakes region after near-extirpation has been notably successful. In the 1960s, only a remnant population of 300 to 1,000 wolves limited to northeastern Minnesota remained.
