Science Corner - Tule Elk

Geoff Benn • June 14, 2024

My wife and I recently drove out to Cowboy Camp in western Colusa County, in an attempt to see the Aurora Borealis during the recent solar storm. While this was mostly unsuccessful, we did get to see a group of at least 20 Tule Elk grazing in the gathering dusk across Bear Creek. They were spectacular as always – they’re one of my favorite local animals and I think one of the most charismatic found in the Inner Coast Range.


Elk can be distinguished from black and white-tailed deer by their larger size, their mane of fur around the neck, and by their white rumps (Waipiti, a common name for North American Elk, is derived from a Shawnee word meaning white rump).


Tule Elk (Cervus canadensis nannodes) are one of three subspecies of elk found in California, with the others being the Roosevelt Elk (Cervus canadensis roosevelti) and the Rocky Mountain Elk (Cervus canadensis nelson). Tule Elk stand out from these and other North American Elk as they are the smallest subspecies, the only one that specializes on relatively dry ecosystems, and the only one that is endemic to California, meaning that they are found here and nowhere else.


When conditions are good, Tule Elk prefer to graze on grasses and annual forbs, but they will also browse shrubs and the lower branches of trees if grazing options are sparse. During the winter and spring months, female Tule Elk (cows) form their own herds apart from the males (bulls), who may band together in small groups or live alone. By late summer, when the antlers of the bulls have fully grown in for the year, the dominant bulls will join a group of cows and will mate with multiple partners while fending off rival males. It is during this period that bugling, the haunting call produced by bull elk, can most commonly be heard.

Tule Elk, estimated to have numbered as many as 500,000 prior to European and American colonization, saw their population decline to just two individuals by the 1870s. This last breeding pair was fortunately located on land owned by cattle barons Henry Miller and Charles Lux, who set aside part of their property for the conservation of the species. By the early 20th century, the population of Tule Elk on the ranch had rebounded sufficiently that the state began attempting to translocate animals to other parts of the state to found new herds. Most of these efforts failed, but two succeeded, including the Cache Creek herd, which was established in 1922 and is now the oldest free-ranging herd in the state.


Translocation and management efforts continued throughout the second half of the 20th century, leading to an impressive recovery for the species, with around 6,000 individuals today, spread across 22 populations. These include both free-ranging herds like those at Cache Creek and contained herds, such as those at Point Reyes and the Tule Elk State Natural Reserve, located on the original site of the Miller-Lux ranch.


There is currently one population of Tule Elk within the Berryessa Snow Mountain National Monument – this is the Cache Creek herd, which numbers around 600 individuals split into two subpopulations spread across the Cache Creek Wilderness and into the adjacent BLM Bear Creek Unit, which abuts the Monument, but isn’t a part of it. Cowboy Camp, located in the Bear Creek Unit near the junction of CA 20 and CA 16, is the best place to see Tule Elk from the Cache Creek herd.

There are two additional populations of Tule Elk located just outside of the Monument at East Park Reservoir and at Lake Pillsbury, to the east and west of Snow Mountain Wilderness, respectively. The Lake Pillsbury population can be reliably seen near the campgrounds on the north end of the lake, with the most activity occurring during breeding season in early fall.


Despite having no major natural predators following the extirpation of the California Grizzly Bear, most Tule Elk tend to be relatively skittish around humans, so if you want to see them up close, your best bet is a pair of binoculars or spotting scope. If you haven’t had the pleasure of seeing Tule Elk in the wild, I encourage you to make the trip out to Cowboy Camp. The best time to see the Elk there is at dusk, when they come down from the hills to graze along the creek and will be easily seen from the viewing platform.

Last year tested us. We watched as the administration attempted to auction off millions of acres of public lands, an unprecedented attack on places we’ve fought to protect for decades. We saw rollbacks of critical environmental protections and threats to lands that belong to all of us. But we also showed up. Together, as a community, we rallied, we organized, and we pushed back against some of the most aggressive land sell-offs ever proposed. And we won some of those fights. In December, just before Congress recessed, Senator Padilla introduced the Protecting Unique and Beautiful Landscapes by Investing in California (PUBLIC) Lands Act , a beacon of what’s possible when we refuse to give up. This isn’t just another bill. It’s a statement that California is refusing to let our public lands become bargaining chips. The PUBLIC Lands Act would protect over 1.7 million acres of California public lands throughout northwest California, the Central Coast and Los Angeles County. That protection includes 550,000 acres of new wilderness and nearly 700 miles of wild and scenic rivers. It includes provisions for forest restoration and fire resilience on another 871,000 acres, work that is desperately needed. This package pulls together three essential bills: Congressman Huffman's Northwest California Wilderness, Recreation and Working Forest Act , which protects 484,733 acres and 479.8 miles of rivers, old-growth forest, salmon streams and wild places that define the North Coast. Representative Carbajal’s Central Coast Heritage Protection Act secures 385,842 acres including critical habitat in Los Padres National Forest, home to California Condors and threatened watersheds. Representative Judy Chu’s San Gabriel Mountains Foothills and Rivers Protection Act that protects 35,335 acres, expanding access to nature for millions of Angelenos who live in communities with some of the lowest park access in the country despite having mountains right in their backyard. The PUBLIC Lands Act matters because it’s happening now when our public lands face their greatest threats. Our champions in Congress aren’t waiting for a better political moment, they’re fighting for these places when the fight matters most. We will be tracking this bill closely and keeping you updated as it moves through Congress. In the meantime, call your representatives and thank Senator Padilla , Representative Huffman , Representative Carabajal and Representative Chu for introducing this legislation. Let them know you support it. Our voices help move good legislation through Congress, especially when the opposition is loud. If 2025 taught us anything, it's that defending our public lands isn’t a one-time battle. It’s the work we do together, every single day. Bryan Pride Tuleyome Policy Director

It’s true! Tuleyome’s Adventures and Engagement Director Nate Lillge has assembled an incredible guide to the trails located throughout the southern portion of our newly expanded favorite monument. As you may know, the monument is jointly managed by both the Bureau of Land Management (under the United States Department of Interior) and the United States Forest Service (under the United States Department of Agriculture). The two agencies collectively manage and maintain 344,476 acres of natural wildlands in the Inner Coastal Range available for the public to appreciate and explore. That’s where Tuleyome comes in, we want to help you traverse and investigate those acres. Tuleyome’s trail guide not only provides a map of the southern portion of the monument with the trailhead names and locations, but it also shows names of the various trails that can be accessed by those trailheads along with the difficulty rating. It also contains a QR code that will take you to detailed information for each trail, including driving directions, trail maps and hike descriptions. If you’d rather go with a group, Tuleyome can help there too. Check out the Upcoming Events tab on our website to register for one or more of our organized hikes. So, if your New Year’s Resolution was to get out on more hikes in 2026, Tuleyome’s got you covered! Check out the Trail Guide here or look for our booth at one of the many community events that we participate in and pick up a printed copy. And don’t forget about our Youth Boot Bank program if your little hiker needs to borrow some boots; just come see Tuleyome’s Education Associate, Geoff Benn, during Boot Bank office hours, which are also listed under the events tab, and we’ll get your little ones outfitted for the trails too.

Stretching from the Bering Straight off the coast of Alaska south to majestic Patagonia, the Pacific Flyway is one of the paramount migratory pathways in the entire world. Hundreds of species ranging from tiny hummingbirds, songbirds like sparrows and warblers, shorebirds like avocets, sandpipers and whimbrels, waterfowl including many species of ducks and geese to great Bald Eagles combine to equal the billions of birds that use the Pacific Flyway each migration season. With California's mild winters, available wetlands and flooded rice fields, and oodles of food, it’s not hard to see why waterfowl species like the striking white and black Snow Goose spend their winters here. As many as a million and a half Snow Geese will be using the Pacific Flyway and tens of thousands of them will remain here, in our region, for the winter. The City of Chico and surrounding communities come together to celebrate “this magnificent spectacle of nature with the Snow Goose Festival of the Pacific Flyway.” By connecting and showcasing artists, authors, educators, guides and volunteers the festival aims to excite and unite the community by increasing appreciation, awareness, conservation and understanding of the resident and visiting wildlife and their habitats in the Northern Sacramento Valley. The three day festival features art and an auction, a banquet, field trips, family activities and exhibits and workshops! Snow Geese (Anser caerulescens) breed in Greenland, Canada, Alaska and the northeastern tip of Siberia and winter in the warmer regions of southwestern British Columbia, south through the United States and Mexico. There are two color morphs, white which are called “snows” (shocking, I know) and the dark morphs which are called “blues”. Snows are all white with black wingtips while blues have dark bluish-gray plumage and a white head, neck and tip of the tail. Both color morphs have orangy-red legs and feet and a pink bill with black edges that makes it look like they are grinning. Sometimes minerals in the soil or water where they’re feeding can stain their white heads making them look orange. Snow Geese are vocal. Very vocal. Some may say they are extremely vocal and they can often be heard from more than a mile away. Frequently Snow Geese and Greater White-fronted Geese travel together as they are very similar in size and needs. Combined flocks of them can often be heard on winter days and nights as they fly high overhead to their feeding grounds. If you’re looking for a fun way to Enjoy Outdoors and learn more about the Pacific Flyway, Snow Geese and their fellow travelers, venture on up to Chico during the weekend of January 22-25, 2026. They’d love to see you at one of the many events! Please visit the website ( https://snowgoosefestival.org/ ) for a list of activities, to register and for more information. Snow Goose Fun Facts! When Snow Geese are resting or feeding, lookouts keep an eye to the sky watching for threats such as Bald Eagles or other predators which prey on old or injured geese. The lookout will vocalize and the entire flock may spontaneously take flight which is pretty stunning to watch. Snow Goose eggshells stain easily which makes aging the eggs easy, the older eggs will appear dirtier while the more recently laid eggs remain creamy white. Snow Geese populations dropped so low in the early 1900’s that hunting was no longer allowed in the eastern states. From the 1970’s and on, the population has boomed so much that some of their tundra nesting grounds are being impacted by their numbers. Once females arrive at their breeding grounds they may spend up to 20 hours a day foraging but consume nearly nothing once they begin incubating eggs. Snow Goose digestion is remarkably quick, requiring only about an hour or two to go from gullet to ground. Snow Geese make epic journeys by wing but they are not lazy on foot either. Within the first month after hatching, goslings may walk about 50 miles with their parents. When waterfowl molt they lose their ability to fly but a molting Snow Goose can outrun many predators. The oldest known Snow Goose was over 30 years old! Word Play. A group of geese on the ground or water is called a gaggle . That same collection of geese but now in the air are called a skein , a wedge or a team . Hunters use the term “ grind ” for an assemblage of geese while culinary artists use the same term to mean goose meat . BUT, if you simply call them a flock of geese, everyone will know what you’re talkin' about! -Kristie Ehrhardt ( kehrhardt@tuleyome.org ) Tuleyome Land Conservation Program Manager
