About the Map
A watershed is a geographic unit that drains water into a specific waterbody. 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.
These maps are created using GPS collar data collected from all collared wolves in Colorado. This includes animals reintroduced from Oregon and British Columbia, as well as wolves that naturally migrated in North Park.
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.
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.
Wolf Activity Maps are produced using U.S. Geological Survey watershed information, frequently known as Hydrologic Units. The Hyrdologic Unit Code (HUC) 10 scale provides detailed information that can help agricultural producers be informed of the general areas where wolf activity is known to exist.
