Sierra Nevada bighorn sheep are an endangered species under Federal law and California law. There is a real opportunity to recover Sierra bighorn because the habitat is intact and there is broad public and agency support for the effort. Sierra bighorn are one of only two only federal endangered species in Yosemite National Park and Sequoia-Kings Canyon National Parks(along with the mountain yellow-legged frog); these parks are excited to see this iconic mammal restored as part of the native fauna within their boundaries. Down-listing goals can be met in the next decade if recovery actions are implemented. Translocations to augment newly created herd units are still needed while the existing herds that serve as translocation stock must be protected.
