Sierra Nevada Bighorn Sheep In Sequoia Kings Canyon - Mount Langley

Mount Langley herd movement data

 

Recent Events

  • 08/21/2018 46 sheep were seen during the annual survey. This number is lower than in 2016 because of the big winter which some sheep did not survive.
  • 09/07/2016 The program staff saw 78 sheep in the annual Langley survey. It appears that the Langley herd unit is doing very well.
  • 02/15/2016 S414, a lamb, moved from lower Diaz Creek to Joe Devil Peak. What a long journey for a lamb in the winter!

The Mount Langley herd was initially reestablished in 1980 with the translocation of 10 Sierra bighorn from the Mt. Baxter herd. The herd was subsequently augmented with an additional 15 animals in the early 80s. Today Mount Langley is one of the largest and most productive herds in the Sierra. In 2016 we estimated that there were at least 90 Sierra bighorn at Mount Langley. Because of its great success, Mount Langley has been used as a source herd for translocations to the Cathedral Range, Mt. Gibbs, Olancha Peak, and Convict Creek in recent years. In summer, bighorn in this herd are highly visible by hikers summiting Mount Langley and hiking through Cottonwood Lakes Basin, over New Army Pass, and north to Soldier Meadows and the Miter Basin.
