For Immediate Release

Presidential Proclamation -- Establishment of the Berryessa Snow Mountain National Monument


- - - - - - -



The Berryessa Snow Mountain area is the heart of northern California's wild Inner Coast Range. Once covered by ocean waters, it is a landscape shaped by geologic forces of staggering power overlain with bountiful but fragile biodiversity. Anchored in the north by Snow Mountain's remote forests and in the south by scenic Berryessa Mountain, this area stretches through unbroken wildlands and important wildlife corridors, a mosaic of native grasslands, picturesque oak woodlands, rare wetlands, and wild chaparral.

Home to the headwaters of the Eel River, and the Stony, Cache, and Putah creeks, Berryessa's waters are a crucial element of this landscape and a vital link to the water supply for millions of people. This dramatic and diverse landscape is a biological hotspot providing refuge for rare plant and animal species and showcasing the human history of north-central California.

Native Americans have inhabited these lands for at least the last 11,000 years. Many tribes, including the Yuki, Nomlaki, Patwin, Pomo, Huchnom, Wappo, and Lake Miwok, and Wintum all played a role in the history of this region, one of the most linguistically diverse in California.

The region's abundant natural resources helped to shape these distinct cultures. Early inhabitants subsisted upon protein-rich acorns in addition to seed and nut crops cultivated through traditional burning practices. Obsidian, chert, and basalt provided important source material for tool production, such as flaked tools and projectile points. The inhabitants also processed and produced both shell and magnesite beads, which they traded with other tribes.

Dense with cultural resources, the Berryessa Snow Mountain area contains a range of ancient settlements from mineral collection sites, and seasonal hunting and gathering camps in the high country, to major villages with subterranean, earth-covered round buildings in the lowlands. In addition to trade routes winding through the hills and mountains, the area is rich with sites that tell the story of early Native peoples: chert quarries where stone was gathered to make tools, task sites where tools were re-sharpened during hunting excursions, food sites where acorn and seeds were ground on large grindstones, and areas with pitted boulder petroglyphs where individuals illustrated their life experiences. The Cache Creek Archeological District, designated on the National Register of Historic Places, illustrates the area's archeological importance.

In the early 19th century, both Spanish and Mexican expeditions explored the region, as did fur trappers for the Hudson Bay Company. These explorers and trappers were often just brief visitors to this landscape, but their explorations and documentation opened the region to further European-American settlement by providing information about conditions, resources, and geography. This later settlement began during the 1840s gold rush. Farming in the region was limited due to the difficult terrain and soils, while cattle and sheep ranching were much more profitable.

From the mid to late 1800s, many small sawmills operated within the forests of the area. The restored 1860s-era Nye homestead cabin, the historic Prather Mill, and remnants of associated railroad logging operations are tangible reminders of these historic uses. Around the turn of the 20th century, the mineral-laden waters and hot springs of the area attracted visitors to resorts and spas advertising their therapeutic benefits. Remains of the foundations of the mineral spring resorts at Bartlett Springs can be spotted by observant visitors today.

Native populations were displaced by the European-American settlement and development of the region in the early to mid-1800s. Many traditional hunting and gathering grounds were converted to grazing and logging and new diseases brought into the area spread to the Native people, greatly impacting the local Native populations and pushing them off of their homelands. Nevertheless, the region's landscape and resources retain deep cultural significance for modern Native communities, including roughly two dozen federally recognized tribes.

The Berryessa Snow Mountain area tells a dynamic geologic story. A relic of ancient times, scientists theorize that Snow Mountain formed as an underwater mountain during the Jurassic Period, 145-199 million years ago. Much of the region is prone to landslides due to weak and pervasively fractured rock, resulting in a diverse topography, including sag ponds and springs, with important values for wildlife and plants. The seismically active Bartlett Springs fault zone has remarkable features including hot springs and geologic outliers with marine invertebrate fossils dating to the Cretaceous Period and Cenozoic Era. The area has two important tension-crack caves, likely also created by landslides. These are classified as significant under the Federal Cave Resources Protection Act of 1988 and provide habitat for the Townsend's big-eared bat.

Rising from near sea-level in the south to over 7,000 feet in the mountainous north, and stretching across 100 miles and dozens of ecosystems, the area's species richness is among the highest in California. This internationally recognized biodiversity hotspot is located at the juncture between California's Klamath, North Coast, and Sacramento Vallejo ecoregions and provides vital habitat and migration corridors for diverse wildlife, including several endemic plant and animal species.

The Berryessa Snow Mountain area is notable for its significant concentration of serpentine soils arising from frequent seismic activity and influence from ancient oceans. Serpentine, California's State rock, is formed from the clashing, subduction, and rising of massive geologic forces, and can be found in significant quantity in the area. These soils lack the nutrients most plants need and often contain heavy metals toxic to many plants, resulting in plants that are unique and endemic to this region. Serpentine outcrops in the area have been the subject of a great deal of botanical, ecological, and evolutionary research, and hold promise for future scientific explorations. Many serpentine plants are listed as rare, sensitive, or threatened under Federal or State law. Examples are: the endemic bent-flowered fiddleneck and brittlescale, the Brewer's jewelflower, Purdy's fringed onion, musk brush, serpentine sunflower, bare monkeyflower, Indian Valley brodiaea, Red Mountain catchfly, and Snow Mountain buckwheat, along with numerous other herbs such as the Lake County stonecrop, coastal bluff morning glory, Cobb Mountain lupine, Contra Costa goldfields, and Napa western flax. There are also plant species that are near-endemics and almost entirely restricted to serpentine soils, such as MacNab cypress, leather oak, swamp larkspur, and Purdy's fritillary.

The Berryessa Snow Mountain area is replete with wild and unique landscapes and climatic micro-regions. These include Cedar Roughs, an important refuge for black bear and a 3,000-acre stand of endemic Sargent's cypress trees. Cache Creek, a California Wild and Scenic River, provides an exceptional, intact riparian habitat and one of the largest wintering populations of bald eagles in the State. Remnants of the grassland prairies that once covered much of interior California still exist at Upper Cache Creek, where there are stands of native grasses with creeping wild rye and meadow barley, and some smaller relict patches of upland bunchgrass.

The 6,000-foot Goat Mountain is home to highly unusual plant assemblages that have created one of the most diverse butterfly regions in California. The Hale Ridge Research Natural Area hosts an important stand of knobcone pine. The ecological sky island of the 7,000-foot Snow Mountain serves as important habitat to a number of key plant and animal species.

The headwaters of the Bear Creek Watershed are a particularly excellent example of the area's serpentinite-based endemism and biodiversity with over 450 plant species, including a magnificent array of wildflowers, along with cypress, manzanita, and willow. Nearly half of California's 108 species of dragonfly and damselfly are found here, as well as 16 reptiles and amphibians, 6 rare insects, and 80 species of butterflies. This area has been an important focus of scientific studies on climate change, including studies of range shifts and isolated populations of species during Pleistocene changes in climate, and on post-fire succession.

The Berryessa Snow Mountain area's wide variety of elevations, many streams, ponds, and rivers as well as diverse plant communities provide excellent habitat for fish, wildlife, and amphibians. The streams and creeks in the Berryessa Snow Mountain area have served as centers for scientific research on hydrology and riparian ecosystems for decades. The riparian habitat linking the Sacramento River, Putah Creek, and Cache Creek provides a home for native birds such as the spotted sandpiper and the rare tricolored blackbird.

Waterways in the area harbor several native fish, including Pacific lamprey, western brook lamprey, rainbow trout, California roach, Sacramento pikeminnow, speckled dace, hardhead minnow, Clear Lake hitch, Sacramento sucker, and prickly and riffle sculpins. The area also provides historic habitat for coastal chinook salmon, Northern California steelhead, and California Central Valley steelhead.

Ponds and seeps throughout the area provide rare aquatic habitat for important plants like eelgrass pondweed, few-flowered navarretia, marsh checkerbloom, and Boggs Lake hedge-hyssop. This aquatic habitat is also home to amphibious species like the foothill yellow-legged frog, California red-legged frog, California newt, Pacific tree frog, western toad, and the northwestern pond turtle.

Numerous reptiles live in the Berryessa Snow Mountain area, including the St. Helena mountain king snake, western fence lizard, western skink, western whiptail, alligator lizard, gopher snake, common king snake, rubber boa, common garter snake, western terrestrial garter snake, western aquatic garter snake, and the northern Pacific rattlesnake.

Many large and small mammals co-exist in this diverse landscape, such as Tule elk, bobcats, mountain lions, black bears, mule deer, beaver, river otter, Pacific fishers, American badgers, Humboldt martens, and the San Joaquin pocket mouse. Most of the animal species in the area have special State or Federal status as sensitive, at-risk or threatened.

Raptors such as burrowing owls, prairie falcon, peregrine falcon, northern goshawk, and bald and golden eagles live and hunt throughout the upland areas. The Berryessa Snow Mountain area also serves as an important migratory corridor for neotropical birds and is home to a plethora of bat and insect species, including the threatened valley elderberry longhorn beetle and the vulnerable pallid bat, western sulphur butterfly, gray marble butterfly, Muir's hairstreak, and Lindsay's skipper.

The protection of the Berryessa Snow Mountain area will preserve its prehistoric and historic legacy and maintain its diverse array of scientific resources, ensuring that the prehistoric, historic, and scientific values remain for the benefit of all Americans. Today, the area is important for ranching and also provides outdoor recreation opportunities, including hunting, fishing, hiking, mountain biking, and horseback riding to a burgeoning population center.
