Science Corner - Coyote Bush

Kristie Ehrhardt • April 4, 2025

Coyote Bush (Baccharis pilularis) is one of my very favorite California native plants. It’s found throughout California and is a commonly seen but perhaps unnoticed species in our region. It seems nobody can quite agree on exactly why its common name is coyote bush but like another California native, the Coyote (Canis latrans) it is a very adaptable species and can thrive in many environments. Like the four-legged coyote, Coyote Bush flourishes in hot and arid chaparral, it can be an occasional woody plant in the grasslands of California, a common understory species in our oak woodlands and riparian areas and a soil stabilizing friend on windy coastal slopes. It can colonize in the shade but really thrives in full sun and pretty much everything else in between. It is able to endure soil and weather conditions that not many other species can ride out.

 

Although the source of the name isn’t really known, some believe that it may have come from both species’ adaptability or their ecological partnership, while others think it may be from the shape of the leaves which maybe *kinda sorta* resemble a coyote’s paw if you squint a bit.

 

Oh, and the smell! I don’t mean to gush but I have such a fondness for the scent of Coyote Bush and catching a whiff of it positively brightens my day. Falling in line with its often underrated and underappreciated presence, I often notice the presence of Coyote Bush by its scent before I even see the plant. I’ve heard it described as smelling like sage, honey, hay, sea air and even soap but to me it smells like pure glee with a dash of spice, dill and fresh air. I wish someone would make a Coyote Bush scented candle but I’m not sure that could do it justice.

 

Coyote Bush is a member of the Asteraceae (Aster) family which includes other favorites such as daisies, sunflowers, marigolds, dandelions and about 32,000 other known species worldwide. It is the largest family of flora in North America. Members of the Aster family have an enormous distribution and occur in subpolar to tropical regions and on every continent except Antarctica. Most members of the Aster family are herbaceous but some species can occur as an annual (completes its life cycle in one year), a biennial (completes its life cycle in two years) or a perennial (lives two or more years) and as woody vines, shrubs or trees. Flowers of the Aster family consist of many tiny florets (disk flowers) surrounded by strap-like bracts (also called ray flowers) which creates the characteristic “sunflower” look.

 

Coyote Bush is a perennial shrub usually less than ten feet tall with many stiff, upright branches and an extensive root system including dense lateral roots and a tap root that may be as long as the shrub is tall. The leaves are bright green, about an inch long with toothed margins and are broadest at the tip. They are covered with surface glands that produce resinous, but not sticky, oils which is where the fabulous scent comes from. This resin helps the plant decrease water loss through its leaves.

 

Coyote Bush is dioecious which means that male and female flowers on separate plants. Most of the year the shrub looks bright green but when it flowers from late summer to late fall it can look somewhat creamy white because of the multitude of tiny flowers. The flowers are pollinated by a variety of insects and in late fall and early winter a gazillion (probably not really that many but pretty close) itsy-bitsy (less than 1/16th of an inch) seeds are released and float away on a puff of fluff like another well-known Aster, the dandelion. Shrubs are most noticeable before and during seed dispersal when they appear ashy white because of the superabundance of tuft and seeds. Although Coyote Bush is popular in native landscaping, people usually only use male plants to avoid the messy seed dispersal.

 

Coyote Bush is somewhat burn resistant due to the high concentrations of fire-retardant organic compounds in its leaves. If the shrub does burn the root crown usually survives and will resprout. Because the many seeds of Coyote Bush are wind-blown with a wide dispersal area it will also readily re-establish itself in post burn and other disturbed areas. It is also deer and graze resistant and drought tolerant.

 

Other fun facts about Coyote Bush:

  • Coyote Bush often supports galls created by a host-specific midge (Rhopalomyia californica) that look like tiny cauliflowers. 
  • Coyote Bush is often called a “pioneer species” because it is one of the first to re-establish following a fire or flood.
  • Coyote Bush provides an important source of nectar and habitat for native birds and butterflies.

For Immediate Release: September 11, 2025  Contact: Nate Lillge, 530-379-8697, nlillge@tuleyome.org Trump Attacks Public Lands, Again Trump Proposes to Eliminate Public Lands Protections through Executive Action Woodland, CA – Yesterday, the Administration furthered their attack on America's public lands by directing the elimination of the Public Lands Rule . This is another step in the Administration’s wholesale assault on our public lands in clear opposition to the will of the people. The Public Lands Rule protects our treasured, multi-use landscapes so they'll be there tomorrow. The Rule recognizes that conservation is a type of land use, along with grazing, timber production, energy development, and recreation. Built on decades of management experience and guided by science and data, the rule provides land managers with essential tools to maintain our public lands, ensure access and protect our resources while supporting the diverse ways that communities depend on public lands. "The Public Lands Rule improves the management of our public lands, empowering the Bureau of Land Management to focus management on the needs of the lands where they work," says Sandra Schubert, Tuleyome Executive Director. "Rescinding the Public Lands Rule will rip authority from local land managers to place it in the hands of D.C. bureaucrats whose main goal is to sell our public lands to the highest bidder. All this in opposition to the overwhelming support for our public lands and their protection." By removing the Public Lands Rule, the Administration is failing ranchers and rural communities. Decision after decision made by this Administration has focused on short-term profit, extraction, and selling public lands to private entities. Supporting rural communities, the backbone of our economy and food systems, means ensuring farmers and ranchers have healthy lands they can depend on. It means empowering local BLM managers who understand what their communities need to thrive and provide for the American people. Overused lands don't recover. Degraded grasslands can't support cattle. Clearcut forests take decades to regrow. Contaminated watersheds poison communities for generations. True support for rural communities means embracing the Public Lands Rule. That is exactly why the American people want and support the Public Lands Rule. The Rule has overwhelming support. When given the chance to comment on the Public Lands Rule, more than 150,000 Americans did – 92% in support. When ranchers, recreationists, and resource companies all depend on the same lands, we recognize that we must use them responsibly to ensure they stay productive for everyone. The choice is clear: Protect our public lands for current and future generations, or consume everything now and leave nothing behind. Without the Public Lands Rule, our cherished landscapes lose protection and one of our greatest treasures, our public lands, is at risk.

On July 10, 2025, we gathered to celebrate the 10th Anniversary of Berryessa Snow Mountain National Monument with the people who worked to establish the Monument in 2015 and add Molok Luyuk to it in 2024. We gathered in Lake County. The event began at the Tallman Hotel with folks gathering, speakers, trivia, food, videos, celebration and music by the Rural Jazz Project. We had folks from throughout the region – the Bay Area to Chico, Ukiah to Sacramento…. We had our partners at the Bureau of Land Management, local government representatives and all aspects of our broad coalition – conservationists, scientists, hunters, hikers, and community members, and more. The presentations and speakers were amazing. Tuleyome put together a reel of Berryessa Snow Mountain National Monument highlights . I was privileged to emcee the event and welcome our speakers and guests. We were honored to have Tribal leadership. Michael Marcks, Vice Chairperson, Executive Council, Habematolel Pomo of Upper Lake graced us with opening prayer. Vice Chairman Michael Marcks was joined in providing remarks by Vice Chair Eddie Crandell, Vice Chairman for the Robinson Rancheria of Pomo Indians and Lake County Supervisor . Gail Totton, Tribal Resources Manager for the Yocha Dehe Wintun Nation , the lead for the addition of Molok Luyuk to the Monument, shared their thoughts on the anniversary and Molok Luyuk. U.S. Senator Alex Padilla spoke to us via video and emphasized the importance of our efforts and our public lands. Luca Moretti read a statement on behalf of Representative Mike Thompson , a legendary champion of public lands, who commended us all and provided Tuleyome with a Certificate of Special Congressional Recognition . We were surprised and flattered with the honor bestowed upon us. Representative Jared Huffman, Ranking Member of the U.S. House of Representatives Committee on Natural Resources , also spoke to us about his efforts to defend our public lands. Our state and local representatives also joined us. Rhiannon Philippi delivered remarks for California Senate President Pro Tempore Mike McGuire. California Senator Christopher Cabaldon spoke to us via video and Sergio Emmanuel Ildefonso Zarate on his staff celebrated with us. Assemblymember Cecilia Aguiar-Curry led a legislative resolution supporting the Monument, which was read by Laura Beltran . Many of our local Supervisors also celebrated with us. Brad Ramussen, Lake County Board of Supervisors , shared his insights. Lucas Frerichs, Yolo County Board of Supervisors , spoke to us and sponsored a Yolo County Board of Supervisor's resolution that was read by Bryan Pride, Tuleyome’s Policy Director . Neal Craig, BLM, Ukiah Field Office Manager , and our partners in protecting this amazing area, joined us and spoke to our collaboration. Interspersed with our speakers, Sara Husby, Tuleyome’s Executive Director when the Monument was established, led us in a series of trivia questions penned by Tuleyome’s own Kristie Ehrhardt. The depth of knowledge of our coalition shone through. And, it was fun. We hope folks enjoyed the prizes. Closing out the event were leaders in the conservation movement. José Gonzalez, founder and emeritus Executive Director of Latino Outdoors , offered his insights on the importance of public lands to all of our communities. Bob Schneider and Andrew Fulks , Tuleyome Co-founders and Tuleyome Advisory Council Members, shared the history of the movement and some stories, bringing us full circle, from the time when the idea of a Monument was a spark in their eyes to the establishment and expansion of the Monument. After the event at the Tallman, many of us headed to Middle Creek Campground, a few miles away for some nighttime fun. There was a nature walk with botany, forest bathing, star gazing, owling, s’mores, camping and laughter. I learned new ways of making s’mores, including a toasted marshmallow with a mini peanut butter cup tucked inside. Delicious! And, as a reminder of how wonderful our coalition is, there was an animal rescue. The morning after the event, many of us went to Judy’s Junction in Upper lake for breakfast. When I arrived with my mom, who had joined us, we saw numerous people under the hood of Jora’s car – Nick, Brendan, Karah, Isobel, Jora and a pair of legs sticking out from under the vehicle that I did not recognize. They were searching for a kitty that had lodged itself in Jora’s engine area. After much hullabaloo, the kitty ran – fast. We all thought – no, not over the highway! But, the little scamp jumped into another newly parked car engine. The chivalrous owner opened his hood and let us at it. I didn’t do much. I offered my shirt as a barrier to the hot engine. The heroes were the others. Folks from inside the diner pitched in, but it was our coalition to the rescue – the folks above and then Kim showed up. I’m not sure how, after all the time and efforts, but she was finally able to reach in and rescue the kitty. I saw her pull the little ebony guy out, hug him and rub her face against his. And I knew – he was no longer abandoned; he had a forever home. And, I was right, the little guy is now living with Kim and her family. I didn’t need the confirmation, but watching our group spend a couple of hours rescuing that little creature reminded me why I love this community. We care – all of us – about the life, the place and the creatures we live with. All of them. Big and small. None of this would have been possible without our generous sponsors: CalWild, Conservation Lands Foundation, Defenders of Wildlife, Sierra Club National, Sierra Club Redwood Chapter, Tallman Hotel and Tuleyome. Thank you so much for your continuing support of Berryessa Snow Mountain National Monument and all of our public lands. And thanks to all of you – everyone at the celebration, those who could not join us, and the kitty rescue team. You are what community is. I am honored to be part of ours. -Sandra Schubert Executive Director
