On Wednesday, May 22, Colorado Parks and Wildlife released the latest map showing wolf activity across the state.

Parks and Wildlife has released the maps monthly since January after reintroducing 10 wolves in Grand and Summit counties in December.

The map depicts watersheds in which collared wolves have traveled between April 23 and May 21. Just because a watershed indicates wolf activity does not mean wolves are present throughout the entire watershed.

The map is made using data from all collared wolves in Colorado. Two of the 10 collars placed on wolves brought to Colorado in December are no longer functioning, but the animals with failed collars are traveling alongside wolves with working collars.

The May map shows the wolves have explored similar territory this month as they have in the past, with a few exceptions.

While wolf activity has been in the Middle Blue River watershed, which ends on the north side of Dillon Reservoir in Summit County, this is the first map that indicates activity in the Upper Blue River watershed. While most of this area is south of Dillon Reservoir, there is a sliver of it north of Interstate 70 near Buffalo Mountain, meaning a wolf has not necessarily crossed Interstate 70.

Additionally, this is the most activity recorded in Routt County since the first wolf activity map was released in January. At least one animal had been recorded in watersheds throughout south Routt County, but this is the first time a GPS point was recorded in the Battle Creek-Little Snake River watershed, which runs to the northern border of the county and state.

At least one GPS point has been recorded in the Middle Eagle River watershed near Avon since the first map was released, but this month’s rendition shows no activity in the area. This is also the first month since January that activity near Vail, or the Gore Creek watershed, was recorded.

The map also shows no activity near Red Feather Lakes when there was the previous month, which is likely related to the death of a reintroduced wolf.

A wolf was found dead on April 18 in Larimer County and was determined to likely have been killed by a mountain lion.

Parks and Wildlife states on its wolf activity map page that the long-term intention is to maintain at least two collars in each pack.

“Through immigration from other states, potential collar failure or loss, and the natural reproduction of pups, the proportion of wolves with collars transmitting data will be reduced over time,” reads the website.
