California oak woodland is a plant community found throughout the California chaparral and woodlands ecoregion of California in the United States and northwestern Baja California in Mexico . Oak woodland is widespread at lower elevations in coastal California ; in interior valleys of the Coast Ranges , Transverse Ranges and Peninsular Ranges ; and in a ring around the California Central Valley grasslands . The dominant trees are oaks, interspersed with other broadleaf and coniferous trees, with an understory of grasses , herbs, geophytes , and California native plants .

These typically use "Resort" in the name, such as "_____ Resort State Park" in West Virginia state parks and "_____ State Resort Park" in neighboring Kentucky state parks , which has 17 such resort parks, the most of any state. Other states use the Resort name inconsistently (like DeGray Lake Resort State Park , the only one out of three resorts in Arkansas state parks ), or have only one such park ( South Carolina state parks ' Hickory Knob State Resort Park ), or do not use
329-622: A state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state , some of the Mexican states , and in Brazil . The term is also used in the Australian states of Victoria and New South Wales . The equivalent term used in Canada, Argentina, South Africa, and Belgium,
376-413: Is provincial park . Similar systems of local government maintained parks exist in other countries, but the terminology varies. State parks are thus similar to national parks , but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks . In general, state parks are smaller than national parks, with

Outside of the southern ranges of coastal wild oak are small areas of oak woodland characterized by Englemann oak. These sites can coincide with coastal live oak, however they can also occur as stands composed almost entirely of Englemann oak. Northern, wetter regions of California are populated with oak woodlands formed from Oregon white oak. These woodlands are associated interior live oak and canyon live oak similar to coastal live oak woodlands, but differ with Pacific madrone and California black oak . The variety of canopy density which results from
470-631: Is both multiple levels of vegetation heights and varied spacing between vegetation to create complex habitat structure both vertically and horizontally because there are more places for species that live in different layers of the vegetation. Among these species, the California quail ( Callipepla californicus ), Beechey ground squirrels ( Spermophilus beecheyi ), Botta pocket gopher ( Thomomys bottae mewa ), Audubon cottontail ( Sylvilagus audubonii vallicola ), deer ( Odocoileus spp), bobcat ( Lynx rufus californicus ), coyote ( Canis latrans ) and
517-577: Is often found on north facing slopes there is more moisture in the soils from protection from the sun ( slope effect ). In southern and central areas, the predominant oak species is coastal live oak which grow on coastal valleys and foothills. In drier regions within this range, coastal wild oak is associated with foothill pine , valley oak and blue oak ; whereas wetter areas are defined by tanoak , canyon live oak and California bay .

The headwaters area of Yulupa Creek in Annadel State Park is cited as one of the best examples of California oak woodlands. Much of this woodland is a relatively pristine ecosystem with considerable biodiversity . An unusual characteristic of this Annadel forest is the high content of undisturbed prehistoric bunch grass understory , testifying to
705-651: The Civilian Conservation Corps and Works Progress Administration . California oak woodland Oak savannas occur where the oaks are more widely spaced due a combination of lack of available moisture, and low-intensity frequent fires . The oak woodlands of Southern California and coastal Northern California are dominated by coast live oak ( Quercus agrifolia ), but also include valley oak ( Q. lobata ), California black oak ( Q. kelloggii ), canyon live oak ( Q. chrysolepis ), and other California oaks. The foothill oak woodlands around
752-552: The Pacific rattlesnake ( Crotalus viridis oreganus ) can commonly be found in California oak woodlands. Aspects of the California oak woodland that are important for wildlife of these habitats are habitat corridors, snags and downed wood. Natural vegetation create habitat corridors that connect the patches of habitat that host species. Habitat corridors provide protection and food for animals that migrate between patches such as deer, mountain lions, bobcats, or gray foxes. Snags are
799-822: The University of California, Davis found that the prominent presence of oak trees in California oak woodlands creates areas of soil that are optimal for new growth. The Bureau of Land Management partnered with the California Biodiversity Council to carry out the Agreement on Biological Diversity, started in 1991, to protect and expand the following oakland wood areas: King Range National Conservation Area , Cache Creek Management Area, Yuba River Watershed in Inimim Forest, Consumes River Preserve, and Fort Ord . The methods used to ensure

It
893-483: The absence of historic grazing or other agriculture . The Morro Bay watershed, located in Central California, is an example of a coast live oak ecosystem. This sub-category of California oak woodland consists primarily of coast wild oak and are predominantly found in coastal regions, but can extend to foothill ecosystems. The composition and characteristics of California oak woodlands varies across
940-544: The area east of the park was used as the site of the first Olympic Village ever built, for the 1932 Summer Olympics in the 10th Olympiad, which Los Angeles hosted. In the late 1940s the city transportation master plan included building a new north–south freeway, the Laurel Canyon Freeway -SR-170, that would have bisected the Baldwin Hills and park site where La Cienega Boulevard currently crosses

The term "lodge" may also refer to a hiking lodge , essentially a large cabin for hikers rather than a large facility with private rooms and a restaurant. Other lodging may include yurts and tipis . Not all parks owned by a state are necessarily part of its state-park system, such as Stone Mountain Park near Atlanta. Some Texas state parks are
1128-437: The diversity of tree species found in different woodland regions causes a wide range of understory grass and shrub density, and plant type. An example of this can be seen by the commonality of annual grasses in open woodlands, a phenomenon that is not seen in dense woodland areas. All three oak species which characterize California oak woodlands can be defined as "long-lived, slow-growing trees." The frequent fires seen within

Annual precipitation in the oak woodland range is 15 to 40 inches (0.38 to 1.02 m), with little precipitation in the summer. Growing season is 6–10 months. Temperatures range 75 to 96 °F (24 to 36 °C) in the summer, and 29 to 42 °F (−2 to 6 °C) in winter. The woodlands in
1692-497: The region have resulted in species such as coastal live oak and Englemann oak (which grow in drier, more fire prone regions) to have developed a resistance to low-intensity fires. This resiliency has resulted in coastal live oak emerging as the predominant species in cleared regions, as the trees have higher fitness to survive compared to less resistant, deciduous oaks. The same cannot be said for Oregon white oak, which populate traditionally wetter, less fire-prone regions, resulting in

In 1864 Yosemite Valley and Mariposa Grove were ceded by the federal government to California until Yosemite National Park was proclaimed in 1890. In 1878 Wisconsin set aside a vast swath of its northern forests as "The State Park" but, needing money, sold most of it to lumber companies within 20 years. Mackinac National Park
1880-404: The state, and of this area about 79%, or 2,322,000 acres (9,400 km ), shows no evidence of past cutting of trees. Recent research by the University of Arkansas Tree-Ring Laboratory has studied several unlogged stands of blue oak woodlands, and suggests that the state may harbor over 500,000 acres (2,000 km ) of such old growth forests . This would make California's oak woodlands some of
1927-472: The state, but are defined by three main oak species throughout coastal regions: coastal live oak , Englemann oak , and Oregon white oak . The concentration of each of these oak species correlates with the location of the woodland throughout California. In the Sierra Nevada range, oak woodland is found on western slopes at elevations of 500 to 3,000 feet (150 to 910 m) in the northern part of

Because of the lack of fires in these northern regions, white oaks can have the threat of being outgrown by conifers growing in the understory. California oak woodland habitats contain some of the most wildlife in California. More than half of the species of terrestrial vertebrates in California are found in oak woodlands. This includes more than 120 species of mammals, 147 species of birds, and 60 species of amphibians or reptiles. The most diversity occurs when there
2068-451: The wildland. This comprehensive survey includes oak woodland maps and inventory data for the ten oak types found in California. By evaluating this new information against current State of California economic growth projections, the location and extent of oak woodlands most at risk of development are identified. Management practices, such as the grazing (or the lack thereof) can lower soil fertility and nutrient level. A study performed by
