They were welcomed to Colorado in the fall of 2015.  The Laramie Foothills bison herd roams north of Fort Collins at Red Mountain Open Space and Soapstone Prairie Natural Area. 'Like' and follow their facebook page Laramie Foothills Bison. You'll see interesting videos and information on the herd.

The ten founding members of this herd can trace their lineage back to Yellowstone National Park, a herd with a unique genetic background and no evidence of having bred with cattle in their history. Unfortunately, due to the disease brucellosis which is endemic in the Yellowstone herd, it is not as simple as just taking animals from Yellowstone and moving them around to establish other conservation herds.

Using assisted reproductive technologies (ART), Colorado State University researchers have generated offspring with these valuable Yellowstone genetics using artificial insemination, embryo transfer, and techniques for washing embryos and sperm to prevent transmission of disease. Three calves produced using these techniques are founding members of the Laramie Foothills herd. The other members of the herd were naturally bred and born under the care of USDA-APHIS and provided for the project.
