This centuries-old oak woodland protects an unusual variety of plants, animals and biotic communities. The moss-draped, fantastically gnarled trees enchant hikers and visitors. This Central Coast park is eight miles west of San Luis Obispo and five miles east of Morro Bay.

The earliest residents traveled from the coast to the interior valleys and back. They subsisted on fish and shellfish found along the coast as well as small and large game, waterfowl, grasses and seeds found inland. Clothing, shelter and tools were fashioned using resources available in the immediate area. Goods that could not be procured or produced locally were obtained through extensive trade networks. Photo courtesy of Nick Stavros L Los Osos When Gaspar de Portolá’s expedition passed through this valley in 1769, the party spotted many California grizzly bears—osos in Spanish. The valley then became known as Cañada de Los Osos. In 1772, most of the grizzlies were killed for food to keep the people living at the Carmel mission from starving. Coast live oak and dune oak scrub Saving the Oaks Oak woodlands were once widespread along the California coast, but most fell victim to clearing, grazing, Gnarled coast live oak firewood cutting and development. A campaign was launched in 1971 to preserve these 90 acres of trees as a state reserve. On June 29, 1972—thanks to the Small Wilderness Area Preservation Foundation and grants from Dart Industries, Inc. and the Federal Land and Water Conservation Fund—the grove was purchased and turned over to California State Parks. natural history The year-round climate is mild, with winter temperatures from 50 degrees to the low 60s and summer temperatures ranging from 65 to 70 degrees. Vegetation Five major plant communities exist within the natural reserve. Coast live oak woodland—These ancient trees grow in areas with high soil moisture. The natural reserve paths lead visitors through a protected coast live oak grove. Docent-led walking tour Great The closed-canopy forest has horned owl multi-trunked trees 20 to 25 feet high. Their twisted trunks and branches may have lichens and mosses hanging above a sparse understory of miner’s lettuce, bracken fern and hummingbird sage. Dune oak scrub—The smaller, 6- to 8-foot live oak trees in the natural reserve are stunted due to mineral depletion, sandy soil, lack of moisture and location. Coastal sage scrub—Dense, highly branched, semi-woody shrubs include California sagebrush, black sage, holly-leaf cherry, mock heather and coast buckwheat. Riparian woodland—Streamside areas at Los Osos Creek feature such tree species as sycamore, arroyo willow, red willow and black cottonwood. Western dogwood and stinging nettle thrive where riparian trees are sparse. Central coastal scrub—Shallow, rocky soils grow dense-crowned shrubs from three to six feet high. Sticky bush monkeyflower and rash-causing poison oak thrive here. Wildlife Coast live oak woodland provides food and shelter for many birds, mammals and insects. More wildlife is visible in spring and fall. The hour after sunrise and the hour before sunset are optimal times for viewing wildlife. Birds in the grove include acorn woodpeckers, Anna’s and Allen’s hummingbirds, western flycatchers, Northern flickers, California thrashers and California towhees. Mourning doves and Brewer’s blackbirds are common grassland species. Red-tailed hawks, American kestrels, barn owls and great horned owls find their prey in these coastal habitats. Resident mammals include the dusky-footed wood rat, California pocket mouse, striped skunk, gray fox, bobcat, coyote and opossum. Dragonflies, butterflies and other insects serve as food for reptiles and amphibians such as Pacific tree frogs, western skinks, Southern alligator lizards and western fence lizards. recreation The easy, flat unpaved trail system covers about 1½ miles.
