CDFW Creates First Bighorn Sheep Herd in 25 Years

The California Department of Fish and Wildlife (CDFW), along with volunteers from around the state, has established a new herd of federally endangered Sierra Nevada bighorn sheep.

“This is the first reintroduction effort of a new herd of Sierra Nevada bighorn sheep since 1988,” said Tom Stephenson, CDFW bighorn recovery program leader.

Historically, Sierra bighorn were abundant throughout the Sierra Nevada; however, by the 1970s, only two herds remained. Disease spread by domestic sheep and unregulated commercial hunting are believed to have caused their demise.

“Many endangered species remain on the brink of extinction with poor prospects for recovery after they receive federal protection,” said Stephenson. “Through our conservation efforts, we have a unique opportunity to reach recovery goals for an alpine specialist that is native only to California.”

During the week of March 25, 2013 10 female and four male bighorn sheep were captured from two of the largest existing herds in the Sierra Nevada and reintroduced to the vacant herd unit of Olancha Peak at the southern end of the range in Inyo County. Six additional females were moved to two small northern herds, Convict Creek and Mount Gibbs, for augmentation of those herds.

Following this recent effort, there are now 10 herds of Sierra bighorn between Owens Lake and Mono Lake. Three additional herds are needed to meet recovery goals. The population currently numbers around 500 animals and is up considerably from a low of just over 100 animals.


The Art of Conservation helps Sierra Nevada bighorn sheep The Department of Fish and Game (DFG) is joining artist and science illustrator Jane Kim to raise public awareness of Sierra Nevada bighorn sheep. This endangered species is one of the rarest large mammals in North America. Kim’s show, “The Art of Conservation,” launches the Migrating Mural to benefit the Sierra Nevada Bighorn Sheep Foundation. 2012-10-03T17:39:48-07:00
