Snow Mountain Wilderness Wildflowers

Every January through May, the hillsides of Berryessa Snow Mountain National Monument become brilliant with color. Slopes many miles away appear orange with California Poppies (Eschscholzia californica) while close inspection of the ground at one’s feet shows many smaller, less noticeable flowers like common fringe pod (Thysanocarpus curvipes). Combined with the perfect temperatures this time of year, now is your chance to get out and enjoy the color and beauty! Here are some of our favorite trails for wildflower spotting.


Pope to Putah: This trail is located west of Lake Berryessa near Pope Valley. The trail winds through chaparral before entering oak woodland near Putah Creek. Warrior’s plume (Pedicularis densiflora), Indian paintbrush (Castilleja affinis), and golden fairy lanterns (Calochortus amabilis) are common in chaparral while poppies (Eschscholzia spp.) and mosquito bills (Primula hendersonii) are abundant in the oak woodland.


Stebbins Cold Canyon: While not included within the boundaries of the monument Stebbins Cold Canyon is surrounded by monument lands and is one of the closest access points to the monument. This is a very popular hiking area – hiking during the week or starting early on the weekend is the best way to avoid the crowds. This time of year it is easy to see why it is so popular – wildflowers, more wildflowers, and views. Western redbud (Cercis occidentalis), lupine (Lupinus spp.), and poppies (Eschscholzia spp.) dominate the display but there are many other species to enjoy. Woodland star (Lithophragma affine), Fremont’s death camas (Toxicoscordion fremontii), and mule’s ears (Wyethia glabra) are common.


Road 53: Heading into the hills west of Guinda, County Road 53 takes hikers through open grassland and into a riparian ecosystem before chaparral takes over. Manroot (Marah fabacea), larkspur (Delphinium sp.), California bee plants (Scrophularia californica), and checker lilies (Fritillaria affinis) are visible along with purple owl’s clover (Castilleja exserta) and many species of lupine (Lupinus spp.).


Redbud Trail: This is a relatively easy hike that provides a wide variety of ecosystems: oak woodland, chaparral, riparian. The wide variety of flowers one sees along this trail makes it worth the trip to the trailhead. Bird’s-eye (Gilia tricolor), warrior’s plume (Pedicularis densiflora), wallflower (Erysimum capitatum), larkspur (Delphinium sp.) and lupine (Lupinus sp.) are common.


Bear Valley: Bear Valley, located north of CA-20, is known for its amazing wildflower displays. Cream cups (Platystemon californicus), goldfields (Lasthenia spp.), fiddlenecks (Amsinckia spp.) and MANY more. When making the trip to Bear Valley, do not forget to look along the roadside on the drive in. You may see mariposa lilies (Calochortus luteus), bunchleaf penstamen (Penstemon heterophyllus), and tidytips (Layia sp.).


West Crockett Trailhead: This trailhead is at a higher elevation and located on the northern side of Snow Mountain Wilderness which means that it typically blooms later in the season than the rest of the monument. Flowers one can expect to see on this trail are columbine (Aquilegia sp.), red larkspur (Delphinium nudicaule), and large camas (Camassia leichtlinii).


These are just some of the trails you can explore to enjoy the flowers. Check out Tuleyome's trail guide which has details about many trails in the region, all of which have great wildflowers.


We hope you get out and enjoy the amazing wildflowers in Berryessa Snow Mountain National Monument. Feel free to share your photos of wildflowers with us by tagging us on Facebook, Twitter, and Instagram!

Bill Grabert is stepping down from his position as treasurer on Tuleyome’s volunteer Board of Directors – we thank him for his many years of service! Bill first joined Tuleyome as a staff member in 2016. His nature-based teaching influenced many youth over the years with school field trips throughout the Berryessa Snow Mountain National Monument region, from Redbud Trail to Conaway Ranch. As part of Tuleyome’s team of instructors for the California Certified Naturalist program, Bill inspired adults to care for the region. His love of the area began as soon as he graduated from college and began working as a geologist in Lake County. Bill has devoted his diverse knowledge and skillset to care for, steward, and enjoy California’s northern Inner Coast Range Mountains for many years. He will be missed on the Board but we look forward to seeing him on the trails! -Nate Lillge (Adventures and Engagement Director)  and Lyndsay Dawkins (Volunteer Tuleyome Board President)

Fifty-eight and a half million acres of America's wildest forests have been protected for nearly 25 years by the Roadless Rule, a conservation cornerstone that could soon disappear. Established in 2001, the Roadless Area Conservation Rule (RACR) , more commonly known as the Roadless Rule, designated "Inventoried Roadless Areas" (IRAs) across our nation's forests, prohibiting new roads from being built. Now, USDA Secretary Rollins wants to rescind it . From Alaska to California, the losses from this rollback would be massive. In Alaska, 92% of the Tongass National Forest could lose protection, threatening one of the world's most pristine ecosystems and the indigenous communities who call it home. California would lose protections across 4.4 million acres spanning 21 national forests , which has the potential to impact treasured places like Inyo, Shasta-Trinity, and the Berryessa Snow Mountain National Monument. Rule Born from Necessity, Not Ideology The Roadless Rule traces back to 1998, when U.S. Forest Service Chief Mike Dombeck saw the agency's vast road system as a major environmental and fiscal problem . To put this in perspective: the Forest Service maintains eight times more miles of road than the Interstate Highway System. The agency had too many roads to properly maintain for safety and environmental purposes, with poorly maintained roads contributing to erosion and other harms across national forests. The road maintenance backlog had ballooned to $8.4 billion while the agency received only 20% of the funding needed to maintain roads to environmental and safety standards. Dombeck proposed a moratorium on road construction in undeveloped forest areas across most of the National Forest System. The agency adopted an 18-month moratorium in February 1999 pending completion of an overall road management plan. Later that year, the agency undertook a rule making process to provide long-term administrative protection for roadless areas. The Forest Service conducted an extensive public involvement process that produced 1.7 million comments , with the majority favoring a strong national policy protecting roadless areas. The resulting Roadless Rule was not and is still not a blanket ban: it makes exceptions to allow access to non-federal land inholdings and pre-existing mineral leases, and allows logging to reduce fire risk, improve habitat or aid in the recovery of endangered species. What began as a fiscally prudent solution to an unwieldy road network became a cornerstone of forest conservation, one that Americans overwhelmingly supported then and continue to support today. The Administration's Claims vs. Reality According to USDA Secretary Rollins , the rule is “overly restrictive”, hinders fire prevention and responsible timber production, therefore the Rule poses “real harm to millions of acres of our national forests.” Rollins linked rescinding the Rule with Presidential Executive Order 14192, "Unleashing Prosperity Through Deregulation .” The reality is different. Rollins' claim ignores what's actually at stake. Roadless areas are essential ecosystems that provide clean air and water while keeping wilderness intact. They also serve as critical refuges for wildlife; 57% of America's most vulnerable species depend on roadless areas for habitat. For the 156 million Americans who visit national forests annually, these areas offer irreplaceable backcountry recreation experiences. Most strikingly, the administration's fire prevention argument is backwards. Scientific research reveals that 88% of wildfires are human-caused , and 95% of these fires start within half a mile of a road. Areas closest to roads experience 53% more fires than would occur by random chance. Less than 3% of wildfires start in wilderness areas more than a mile from roads. This research indicates that more roads through our forests are more likely to increase fires and would outweigh the effects of improving fire containment. While the administration claims roads improve fire response, fire management teams consistently identify inadequate resources and personnel shortages, not roads , as the primary barriers to effective wildfire management . Rather than building roads that increase fire risk, fire management experts advocate for investing in cultural and prescribed burns, fire mitigation and forest restoration, proven approaches that are underfunded but key to preventing future fires and reducing fire magnitude. What's Next? Rescinding the Roadless Rule will require a public comment period that has yet to be announced. This is when we can all share our views. Tuleyome will be following this issue closely and will be commenting.

The short answer is honestly, pretty much anywhere! Because the 344,476 acre Berryessa Snow Mountain National Monument (the Monument) is located in the rural areas of Colusa, Glenn, Lake, Mendocino, Napa, Solano and Yolo counties you will have a great view of the dark night sky, free from urban light pollution from virtually anywhere within its boundaries! The Monument is an easy drive from not only the metropolitan Sacramento area but also from the San Francisco Bay Area as well as the North Bay communities making it an easy day trip. If you’re here especially for the Perseid meteor shower though it might be a very long day since best viewing happens between the hours of midnight and early morning. If you’re adventurous and up for an all-nighter, be certain to pack plenty of water and snacks and be sure to pull over only where it is safe and you’re not blocking a road, especially when it’s dark. Also always keep safety in mind and look out for wildlife as the Monument is home to black bears, mountain lions, coyotes, tule elk and bobcats that may be traveling through the area as well. If you’d like to stay a night (or several), there are multiple developed campgrounds to choose from inside the Monument boundaries. If you’re up camping, check out The Blue Oaks Campground, Indian Valley Campground, Hunting Creek Campground, Deer Valley Campground, Lower Nye Campground, West Crocket Campground or Kowalski Camping area just to name a few of the sites available for overnight stays. Before you go though, please do check with the United States Forest Service or the Bureau of Land Management websites for details on the particular camping area you’re interested in as well as current conditions, requirements and fire restrictions. The Monument also offers primitive camping in the three wilderness areas located within the Monument boundaries. Cache Creek Wilderness, Cedar Roughs Wilderness and Snow Mountain Wilderness present nearly unlimited opportunities for dispersed camping or backcountry camping (areas located outside of designated campgrounds). Although camping is allowed and encouraged, these areas have no amenities such as tables, toilets, available water or waste removal and require you to pack out all trash and waste. There are no motorized vehicles allowed within Wilderness areas and they provide places for deep solitude with nature. Camping in Wilderness areas or other dispersed camping areas require visitors to understand and follow the Leave No Trace principles of outdoor recreating as well as planning ahead and knowing the area and what to pack. That said, other than the trees potentially blocking some of the night sky, you’re sure to avoid urban light pollution and have an unobstructed view of the night sky from practically anywhere within the Monument! -Kristie Ehrhardt ( kehrhardt@tuleyome.org ) Tuleyome Land Conservation Program Manager
