Monumental Questions - What is the Blue Ridge Berryessa Natural Area?

Kristie Ehrhardt • November 9, 2021

The Blue Ridge – Berryessa Natural Area (BRBNA) is a conservation area composed of nearly 800,000 acres of land located roughly 90 miles west of Sacramento and about 100 miles northeast of San Francisco. It extends from just north of Interstate 80 near the town of Fairfield, north to the southern edge of the Mendocino National Forest and encompasses much of the Inner Coastal Range. Although the boundaries of the Blue Ridge – Berryessa Natural Area are conceptual and informal, they do include some of the acreage within the Berryessa Snow Mountain National Monument.


The Blue Ridge – Berryessa Natural Area was named for two locally prominent features, the Blue Ridge Mountains and Lake Berryessa, and includes portions of Napa, Yolo, Solano, Lake and Colusa Counties. It includes both privately owned land as well as federal, state and local public recreation land. The area is relatively undisturbed by development encroachment and existing land uses include private ranches and a few small, locally owned businesses as well as land trust protected preserves and easements. The University of California’s Natural Reserve System owns and manages three reserves located in the Blue Ridge – Berryessa Natural Area including McLaughlin Reserve, Quail Ridge Reserve and Stebbins Cold Canyon Reserve. These reserves are dedicated to a broad array of research and educational opportunities including wild turkey and ringtail studies, plant ecology, wildlife biology, Lyme disease studies, geology, soils and more.


The Blue Ridge – Berryessa Natural Area supports many habitat types including serpentine, chamise and lower montane chaparral, oak woodlands, valley and foothill grasslands and mixed riparian woodland. Wildlife species found in the area include large mammals such as mountain lion, black bear, coyote, bobcat and deer. Other species observed include ringtails, raccoons, turkeys, many reptiles and amphibians and native fish including the Sacramento Roach and the California Pike Minnow. Over 100 species of birds including Bald and Golden Eagle have also been documented. The Blue Ridge – Berryessa Natural Area also supports habitat for several endemic plant species that occur only on serpentine soils found here. Because of the diversity of species and habitat types, the region has been recognized as one of the most diverse areas in California. Recreational opportunities include wildlife viewing, hiking, rafting, horseback riding, nature camping, photography, and hunting.


The area is overseen by the Blue Ridge Berryessa Natural Area Conservation Partnership. With over 100 participants ranging from privately owned ranches, nonprofits, county, state and federal agencies; the focus of the partnership is to preserve recreational lands, wild areas, agricultural lands and rural ranches through conservation easements and public ownership. In 2002, the Partnership received the California Governor’s Environmental and Economic Leadership Award.

Game Cameras at Conaway Ranch!

By Geoff Benn • June 5, 2025
A river otter making its way up the slide. Looking to take a break with some cute video content? This month we placed game cameras looking into an otter slide at Conaway Ranch. Otter slides are paths worn into riverbanks by repeated use by otters and other animals. The slides at Conaway are quite active, so we’ve been able to get some great footage, including otters, beavers, racoons, snakes, and more! 

Policy Corner: The Public Lands Rule: The Significance of Conservation

By Bryan Pride • June 5, 2025
Since April 2024, America's public lands had something they'd never had before: a rule that treated conservation as equal to all other land uses. The Public Lands Rule , introduced by the Biden Administration, formally recognized conservation as a legitimate practice of multiple use, putting conservation on equal footing with recreation, grazing, and resource extraction. Built on decades of management experience and guided by science, data, and Indigenous knowledge, it gives land managers tools to maintain healthy ecosystems while supporting all the diverse ways we depend on public lands. It acknowledges a simple truth: conservation must be valued equally to all other land uses. Now there is growing pressure to rescind it. Why This Matters The environment around us is free-flowing, it's not confined to state borders or county lines. When mining operations contaminate watersheds in Northern California, it impacts the local businesses who depend on healthy rivers downstream, the agricultural communities that rely on clean water, and the families who've been camping along those waterways for generations. The Public Lands Rule recognized this interconnected reality and gave land managers agency to address problems before they spread across California's diverse landscapes, protecting the long-term viability of grazing allotments, recreation areas, and rural livelihoods that all depend on healthy public lands. This interconnected reality is exactly why the Public Lands Rule matters. The Rule is designed to ensure that the places we depend on, whether for weekend camping trips, or cattle grazing, stay healthy enough to support these uses long-term. When an area becomes overgrazed and doesn't recover, access to those grazing allotments is permanently lost, reducing ranchers' ability to maintain their livelihoods and harming local food production. Poor use or overuse of our public lands creates ripples of negative impact that hurt all communities. The Rule's main objective is simple but revolutionary: make sure our public lands stay productive for everyone who depends on them, rather than degrade them. The Rule created practical tools that built in accountability and prioritized future generations' access to healthy public lands. Restoration Leases : 10-year agreements allowing a variety of entities such as, conservation groups, tribes, and nonprofits to restore damaged landscapes—fires restoration, restoring wildlife habitats and cleaning up abandoned mining sites that currently scar some of our most beautiful public lands. Mitigation Leases : A tool that allows land users or other entities to offset impacts from their activities over specified time periods, creating partnerships between different land users and conservation groups to address environmental impacts on public lands. Strengthened Protection for Critical Areas : Clearer guidelines for protecting Areas of Critical Environmental Concern—the most special and fragile places that often provide the best wildlife viewing, the cleanest water sources, the most pristine camping experiences and the richest biodiversity. The False Dichotomy: Multiple Use vs. Conservation The main argument being used to encourage the rollback of the Public Lands Rule is " multiple use ", the legal principle requiring Bureau of Land Management (BLM) lands to serve many different purposes. The current Administration claims the Public Lands Rule hinders multiple uses of public lands. Why? The Rule calls for restoring degraded areas and making science based decisions. Contrary to their actual meaning, the current Administration interprets "restoring" and "science based decisions" as "locking up land". Land locking, where access gets completely cut off, is a real concern in some areas—it prevents both recreation and grazing. However, land locking is not what the Public Lands Rule promotes. In reality, it is promoting land healing. Take grazing for example. The Rule empowers BLM to use restoration leases in conjunction with existing grazing permittees to restore degraded rangeland. Monitoring who is grazing where and the number of permits issued for specific areas is a means to ensure sustainable grazing and prevent overuse. Many ranchers and land managers supported the Rule because they understand that healthy land is productive land. Overgrazing and environmental damage hurt their livelihoods too. The same principle applies to fire recovery. When public lands are damaged by sweeping wildfires, there is a need for active restoration: replanting native vegetation, stabilizing soils, removing hazardous debris. Restoration has to take place before safe recreation, grazing and other uses can resume. At times, restoration requires temporarily limiting access to burned areas as they recover. The goal is to allow for our lands to recover and heal before we start depending on them again with our multiple uses. Land restoration is not just limited to grazing or extraction; it is essential for recovering from wildfires. Whether it's grazing, recreation, or extraction, the Public Lands Rule isn't about stopping these uses, it's about understanding that healthy ecosystems are prerequisites for multiple use, not obstacles to it. You can't have sustainable grazing on degraded rangeland, quality recreation in fire damaged landscapes, or responsible extraction without considering long-term impacts We Are Public Stewards The Public Lands Rule represents a historic shift in how we value conservation, its potential rollback is a setback. But the vision it represents, conservation as a form of legitimate multiple use, remains essential and is not gone. As stewards of these 245 million acres, we have the power to practice conservation in our own actions and advocacy. Every time we practice Leave No Trace, support local businesses that operate responsibly on public lands, and make our voices heard in land management decisions, we're building the foundation for balanced stewardship that benefits everyone. Our public lands belong to all of us, which means we each have the power, and responsibility, to be good stewards of the lands we love. -Bryan Pride ( bpride@tuleyome.org ) Certified California Naturalist Policy Director
