CPW releases updated collared gray wolf activity map to inform Coloradans on general areas inhabited by gray wolves in Colorado

Collared gray wolf activity recorded by CPW from Jan. 23, to Feb. 27, 2024. Larger map is linked below and available at cpw.state.co.us.

DENVER - An updated map was published today on Colorado Parks and Wildlife’s website to continue to inform the public, recreationists and livestock producers on where collared wolves have been in the past 35 days. This map will be updated with new information on a monthly basis, produced on the fourth Wednesday of every month, reflecting data for the past 30 days or so.

These maps are created using GPS collar data collected from all collared wolves in Colorado.

Notable movements
Recent wolf collar data shows that two wolves traveled broadly in the last month from western Routt County into eastern Moffat County. 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.

About the GPS collar data

Currently, the collars are programmed to record a position every four hours.
Once four locations have been recorded, the packet of four locations is then transmitted via satellite to CPW biologists.
The frequency of both position recording and transmission of the data can be delayed by a number of factors such as dense cloud cover, closed terrain, etc.
By looking at the data, CPW staff can learn where wolves have been, but they cannot tell where wolves are at a current point in time, nor can they predict where the wolves will go.
To protect the wolves, specific GPS data will not be shared.

CPW’s new Map Indicating Current Collared Wolf Activity in Colorado.

This map depicts watersheds where collared wolves in Colorado have been for the last 30 days or so. A watershed is a geographic unit that drains water into a specific waterbody. These are also known as Hydrologic Unit Codes (HUC). Information is shared at the HUC 10 level. 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. The HUC 10 scale provides detailed information that can help agricultural producers be informed of the general areas where wolf activity is known to exist without being too general (i.e. as a county level map would be), and also is not so specific so as to risk the protection of individual wolves (as a finer scale HUC12 map would be). More can be learned about HUCs at https://water.usgs.gov/GIS/huc.html.

In order for a watershed to indicate wolf activity, at least one GPS point from the wolf collars was recorded within the boundaries of the watershed. Simply because a watershed indicates wolf activity, it does not mean that a wolf or wolves are present throughout the entire watershed nor that they are currently in the watershed.

CPW reserves the right to buffer maps that will be shared with the public if doing so protects wolf welfare during sensitive times of the year (e.g., breeding, denning, or other sensitive times).

At this point, all known wolves in Colorado have functional GPS collars. This allows for an accurate depiction of the watersheds where wolves are known to be active. It should be expected that through immigration from other states and natural reproduction of pups, the proportion of wolves that have collars will be reduced over time. Therefore, the accuracy of this map will be diminished over time as the activity of uncollared wolves may not be included in this map.

Forward

CPW is an enterprise agency, relying primarily on license sales, state parks fees and registration fees to support its operations, including: 43 state parks and more than 350 wildlife areas covering approximately 900,000 acres, management of fishing and hunting, wildlife watching, camping, motorized and non-motorized trails, boating and outdoor education. CPW's work contributes approximately $6 billion in total economic impact annually throughout Colorado.
