Collared Activity Update: February 2​8, 2024 - March 25, 2024  (Download PDF​)

Colorado Parks and Wildlife’s ​Collared Gray Wolf Activity Map​ will help inform the public, recreationists and livesto​​​ck producers on where wolves have been in the past 30 days or so. This map will be updated with new information on a monthly basis, produced on the fourth Wednesday of every month, and will reflect data for the prior month, give or take several days. 
These maps are created using GPS collar data collected from all ​​collared wolves in Colorado.  

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. 

​​Notable Updates

  • ​This map was created using GPS data from all functioning collars in Colorado.​​​​​

  • One of the collars placed on a wolf translocated from Oregon is no longer providing signals to CPW biologists. The animal with the failed collar is traveling with another animal with a functional collar, which currently allows CPW to monitor that animal. CPW has confirmed that the animal with the malfunctioning collar is still alive based on visual confirmation from an airplane. 

  • A collar on another wolf has been identified as partially functional and may not be fully functional in the near future.​

  • There have been no wolf mortalities in Colorado and no reported livestock depredation in the last 30 days.​

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

This map depicts watersheds where the​ collared wolves in Colorado have been for the last 35 days. 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 appr​opriate 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., mating season).

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. Therefore, the accuracy of this map will diminish over time as the activity of uncollared wolves may not be included in it. The long-term intention is to maintain at least two collars in each pack.
