Occupancy Survey Season Summary!
We've wrapped up a successful season surveying for bighorn sheep and mountain goats in the north-west corner of Yellowstone National Park! Much appreciation goes out to all the collaborators, agencies (especially those "behind-the-scenes" folks), and private land owners who graciously allowed us to cross their land to access some of our more remote sites. You can view a summary of our season here!

2012 Occupancy Surveys
The crew is having a blast finding bighorn sheep and mountain goats for the project's habitat-focused studies (see our Science page, Occupancy Studies). Amidst the heat, bugs, and lightning storms, we have made a great start to the season, with 69 total observations of mountain ungulate groups! Watch a quick video of some of the sheep and goat sightings.
