In support of the California Department of Fish and Wildlife and its effort to keep hunters and anglers informed, Pete Thomas Outdoors, on Thursday or Friday, posts marine biologist Carrie Wilson's weekly California Outdoors Q&A column:
Question: Why are there no elk in the central or southern Sierra Nevadas? It seems like ideal habitat comparable to that found in Colorado, but the Rocky Mountain Elk Foundation doesn’t even show it as a historic range for elk. Is there some reason they could not and do not thrive in the high Sierras, or at least the foothills? (Nick C.)
Answer: It’s true that the historic range of elk in California did not include the Sierra Nevada range. According to California Department of Fish and Wildlife (CDFW) Statewide Elk and Antelope Coordinator Joe Hobbs, historically tule elk were found in the Central Valley, coast range and the Sierra foothills, but did not occupy the higher elevation regions of the Sierra Nevada.
Previous studies suggest that the Great Basin, combined with the Sierra Nevada and Cascade ranges, served as a western barrier to the natural movement of Rocky Mountain elk (typically found in Colorado, Idaho, Utah, Wyoming and Montana).
Hobbs also says elk are slowly expanding in California and we have received reports of elk in various parts of the Sierra (Plumas, Sierra and even Tuolumne counties). Currently, California has three subspecies of elk. In addition to the tule elk of the Central Valley and foothills, Roosevelt elk are found in the north coast area and the coastal interior regions, and Rocky Mountain elk reside in northeastern California.
Although the Sierra does seem to be composed of habitat capable of supporting elk, historically this was not the case due to the topography of California. Tule elk were found in the Central Valley and coast range and evolved for utilization of these habitat types and not those found in the higher elevations of the Sierra Nevada. The Great Basin and various mountain ranges prevented the Rocky Mountain elk from dispersing into the western portion of the Sierra Nevada range.
