North Fork Big River
The Big River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map , accessed March 9, 2011 river in Mendocino County, California, that flows from the northern California Coast Range to the Pacific Ocean at Mendocino, Mendocino County, California. From the mouth, brackish waters extend 8 miles (13 km) upstream, forming the longest undeveloped estuary in the state. History Pre-European contact, the lands about the Big River belonged to the Me-tum’mah, or Mitom Pomo. This sub-tribe of the Northern Pomo lived in the area of Little Lake Valley near Willits and claimed the coast from south of the Noyo River at what is now Fort Bragg, to just north of the Navarro River, eighteen miles south. They had a settlement, Buldam, on the north bank of the river, near its mouth, but its exact location is unknown and stories about its date of settlement are conflicting. Big River was named for the giant redwoods that once lined its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mendocino Headlands State Park
Mendocino Headlands State Park is a California State Park in Mendocino, California Mendocino ( Spanish for "of Mendoza") is an unincorporated community and census-designated place (CDP) in Mendocino County, California, United States. Mendocino is located south of Fort Bragg at an elevation of . The population of the CDP was 9 .... It consists of of undeveloped seaside bluffs and islets surrounding the town of Mendocino, two beaches (Big River Beach and Portuguese Beach), and the much larger Big River Unit stretching for along both banks of the nearby Big River. The park began operation in 1974, after several years of concern and discussion from citizens about the possibility of blufftop development. The Big River Unit was added in 2002. Headlands The headlands themselves are rocky bluffs overlooking the Pacific Ocean, surrounding Mendocino. The section of headlands along the south side of Main Street in Mendocino is narrow and covered by blackberry and rose brambles. To t ...

Russian River (California)
The Russian River (Southern Pomo: ''Ashokawna'', es, Río Ruso) is a southward-flowing river that drains of Sonoma and Mendocino counties in Northern California. With an annual average discharge of approximately 1,600,000 acre feet (2.0 km3), it is the second-largest river (after the Sacramento River) flowing through the nine-county Greater San Francisco Bay Area, with a mainstem long. Names The Southern Pomo know the river as Ashokawna (ʼaš:oʼkʰawna), "east water place" or "water to the east", and as Bidapte, "big river". Juan Rodríguez Cabrillo and his expedition may have travelled as far north as the Russian River in November 1542 before storms forced them to turn back south towards Monterey. The earliest Slavic name for the river, Slavyanka, appears on a Russian-American Company chart dated 1817. In 1827 the Spanish called it the San Ygnacio, and in 1843 the Spanish land grant referred to it as Rio Grande. The river takes its current name from Russian Iv ...

Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Life Protection Act
The Marine Life Protection Act (MLPA) was passed in 1999 and is part of the California Fish and Game Code. The MLPA requires California to reevaluate all existing marine protected areas (MPAs) and potentially design new MPAs that together form a statewide network. The MLPA has clear guidance associated with the development of this MPA network. MPAs are developed on a regional basis with MLPA and MPA-specific goals in mind and are evaluated over time to assess their effectiveness in meeting these goals. The five main goals of the Marine Life Protection Act are to maintain the diversity of marine ecosystems, conserve its populations, better educate people on human-marine life interactions, protect habitats, and effectively enforce MPAs. The establishment of this policy is an important step in expanding science-based management and decision making regarding policies. Overview Unlike terrestrial conservation, marine conservation often lacks a systematic approach to conserving biodivers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Protected Area
Marine protected areas (MPA) are protected areas of seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations (such as with the Phoenix Islands Protected Area), MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish. The value of MPA to mobile species is unknown. There are a number of global examples of large marine conservation are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

Mendocino Woodlands State Park
The Mendocino Woodlands State Park is a group camping facility located at 39350 Little Lake Road, Mendocino County, California, inland from the town of Mendocino. It was built as a Recreational Demonstration Area by the Civilian Conservation Corps. Mendocino Woodlands consists of approximately of land along the Little North Fork of the Big River and is surrounded to the north, east, and west by the Jackson Demonstration State Forest. To the south, the park abuts the Big River State Park. It was declared a National Historic Landmark on September 25, 1997. History Mendocino Woodlands was one of forty-six campgrounds (including Camp David) created by the Works Progress Administration and the Civilian Conservation Corps in the 1930s. Its rustic wood-and-stone buildings, built by the WPA are surrounded by second-growth redwood forest. Like the other campgrounds, Mendocino Woodlands was originally planned as a site for youth summer camps in which the participants would be int ...

Jackson Demonstration State Forest
Jackson Demonstration State Forest is a public forest in Mendocino County, California managed by the California Department of Forestry and Fire Protection. It is the largest demonstration forest operated by the State of California. The forest land, located along California State Highway 20 between Willits and the coastal city of Fort Bragg, was formerly owned by Caspar Lumber Company. The forest holds sacred value as an ancestral home and ceremonial site for the Coyote Valley Band of Pomo Indians. The that make up the forest were purchased in 1947 and the demonstration forest was created in 1949. Coast redwood is the most common type of tree in the forest, but there is also Douglas fir, grand fir, hemlock, bishop pine, tanoak, alder, madrone ''Arbutus'' is a genus of 12 accepted speciesAct.

Montgomery Woods State Reserve
Montgomery Woods State Natural Reserve is a 1,323-acre (535 ha) state-owned park located in the Coastal Range in Mendocino County, California, United States. The Reserve occupies the headwaters of Montgomery Creek, a tributary of Big River, which flows into the Pacific Ocean at Mendocino Headlands State Park. The virgin groves of Coast Redwood (Sequoia sempervirens) in Montgomery Woods are examples of a now rare upland riparian meadow habitat; most other preserved redwood groves are on broad alluvial plains. The Reserve is accessed from a parking area along Orr Springs Road west of Ukiah, California, or east of Comptche, California. A moderately steep trail from the parking area climbs uphill along Montgomery Creek about three-quarters of a mile. Once in the grove, the trail makes a meandering loop, with substantial use of boardwalks to protect the fragile forest floor. The reserve was initiated by a 9-acre (3.6 ha) donation from Robert T. Orr in 1945, with donated since 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequoia Sempervirens
''Sequoia sempervirens'' ()''Sunset Western Garden Book,'' 1995:606–607 is the sole living species of the genus '' Sequoia'' in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, coastal redwood, and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to in height (without the roots) and up to in diameter at breast height. These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. The name sequoia sometimes refers to the subfamily Sequoioideae, which includes ''S. sempervirens'' along with ''Sequoiadendron'' (gi ...

Old Growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
