The Greater Yellowstone Area Mountain Ungulate Project

The Greater Yellowstone Area Mountain Ungulate Project is a collaborative research initiative to study the ecology and population dynamics of bighorn sheep and mountain goats throughout the Yellowstone ecosystem.

Our mission is to collect critical information on these two regal mountain ungulates for the applied conservation and management by wildlife and natural resource agencies.

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.
