​​Occupancy Survey Season Summary!
October 22, 2012

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
July 15, 2012

The crew is having a blast seeking bighorn sheep and mountain goats for the project's habitat-focused studies (see our Occupancy Habitat Modeling page). So far this season, we have completed four trips into the Tom Miner Basin and north-western Yellowstone National Park backcountry, logging a total of 91 miles and 35,820 feet in elevation gain in 17 days (13 nights). 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.

Welcome to the new website! Take some time to explore the site and learn more about the project's extensive plans to study bighorn sheep and mountain goat across the greater Yellowstone area.


Bighorn sheep and mountain goat research in the greater Yellowstone area is underway!!
October 1, 2011

Telemetry studies and occupancy surveys have been successfully initiated in several regions of the GYA:

  • In the winter of 2010-2011, the Wyoming Game and Fish Department captured and collared eight bighorn sheep ewes in the Gros Ventre National Forest and the National Elk Refuge, located near the Jackson, Wyoming area. These sheep were collared with a dual VHF-GPS collar for spatial and demographic research in an area where mountain goats are absent. For the winter of 2012, plans are underway to instrument an additional seven ewes.
  • In August 2010, three mountain goats in the Palisades, Idaho area were captured and instrumented also with dual VHF-GPS collars by the Idaho Department of Fish and Game. This area is only occupied by mountain goats. An additional nine mountain goats will be captured during winter 2012.
  • Plans are also in place to instrument a total of 15 bighorn ewes and 15 mountain goats within the Pilot-Cache Creek and Sunlight Basin study sites of Wyoming during winter 2012, in collaboration with Yellowstone National Park, the Shoshone National Forest, and Wyoming Game and Fish Department.
  • During the summer of 2011, occupancy surveys were conducted under the guidance of Montana State University graduate student Megan O'Reilly as part of her thesis work. These ground surveys collected spatially precise mountain ungulate locations primarily around the Tom Miner Basin area in the Gallatin mountain range of Montana, as well as the Electric Peak area in Yellowstone National Park. These areas are occupied by both bighorn sheep and mountain goats during the summer months.

The Idaho Falls Post Register published a story on Sept. 8, 2011 about the recent instrumentation of three mountain goats in the Palisades, ID area by Holly Miyasaki, Idaho Fish and Game, as a part of the Mountain Ungulate Project.
