Bighorn Sheep in Nevada's Great Basin

One of Nevada's last remaining populations of bighorn sheep could be in danger, according to wildlife officials.

Grazing domestic sheep near the Great Basin National Park have the potential to carry diseases that the wild, bighorn sheep are not used to.

"What we've learned is that over three-quarters of those bighorn sheep home ranges are on active domestic sheep allotments, and that's a big issue because of the disease domestic sheep can pass on to bighorn," said Bryan Hamilton, wildlife biologist.

According to Hamilton, domestic sheep are built to survive with diseases, living in close proximity to one another and not get sick. Bighorn sheep, however, are just the opposite.

"On a statewide and regional level, these disease outbreaks have wiped out entire populations of bighorns, it's truly catastrophic when it happens," Hamilton said.

Outside of Alaska, Nevada has more bighorn sheep than any other state.
