Two gray wolves were on the move west across Colorado over the last month, according to the latest tracking data released by state wildlife officials.

The latest data from the wolves’ GPS tracking collars showed the two wolves moving from western Routt County into eastern Moffat County, Colorado Parks and Wildlife said in a news release.

CPW each month releases an updated map that shows the collared gray wolves’ movements over the last 30 days. The map released Wednesday showed the 12 collared wolves had covered vast areas of the state, including Jackson, Larimer, Grand and Summit counties to the east, and Eagle, Routt, Garfield, Rio Blanco and Moffat counties to the west.

“CPW continues to work with livestock producers to provide conflict-mitigation techniques, and will continue to conduct outreach/education in areas that are likely to have wolves,” CPW said in the release.

The data is compiled by recording the wolves position once every four hours and is transmitted to state biologists after four locations have been recorded.

CPW said the data is useful to see where the wolves have been, but staff cannot tell exactly where the wolves are at any point in time.

The data is then displayed on a map that shows which watersheds the wolves have been in over the last 30 days.

“Watersheds are the appropriate mapping unit to display wolf activity information because wolves are far more likely to use geographic features to affect their distribution than they are political boundaries,” CPW said.

Wildlife officials said they reserve the right to “buffer” the wolves’ locations on the map if it means protecting the wolves’ safety.

CPW said the accuracy of the map will diminish over time as the animals breed in the wild and as other uncollared wolves potentially move into the area from other states.
