San Joaquin Biosphere Reserve
The San Joaquin Experimental Range is an ecosystem research experimental area in the foothills of the Sierra Nevada. The range is located in O'Neals, California, outside of the Sierra National Forest about north of Fresno, California. The range includes a portion of California grassland and California woodlands with blue oak, interior live oak, and bull pine. The San Joaquin Experimental Range was established after a statement on the need for an experimental area in the San Joaquin Valley foothills was prepared in 1934. The initial purpose for the San Joaquin Experimental Range was to learn how to better manage these lands and investigate resource and animal husbandry problems associated with maintaining a commercial cattle herd on a year-round basis on the foothill rangelands. San Joaquin lands were purchased in 1934 (), with additional purchases in 1936 () and 1937 (). In 1938, another 64 ha were obtained under authority of the Weeks Forestry Act. Of these, 32 ha have been de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madera County, California
Madera County (), officially the County of Madera, is a county at the geographic center of the U.S. state of California. As of the 2020 census, the population was 156,255. The county seat is Madera. Madera County comprises the Madera, CA Metropolitan Statistical Area, which is included in the Fresno-Madera, CA Combined Statistical Area.

Weeks Act
The Weeks Act is a federal law (36 Stat. 961) enacted by the United States Congress on March 1, 1911. Introduced by Massachusetts Congressman John W. Weeks and signed into law by President William Howard Taft, the law authorized the United States Secretary of Agriculture to "Examine, locate and recommend for purchase ... such lands within the watersheds of navigable streams as ... may be necessary to the regulation of flow of navigable streams...." This meant that the federal government would be able to purchase private land if the purchase was deemed necessary to protect rivers' and watersheds' headwaters in the eastern United States. Furthermore, the law allowed for land acquired through this act to be preserved and maintained as national forest territory. Six years earlier, the Transfer Act of 1905 transferred control over the federal forest reserves from the General Land Office of the Department of the Interior to the Department of Agriculture and its Forest Service.

Ecological Experiments
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource management (ag ...

Sierra Nevada (United States)
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils Postpi ...

Agribusiness
Agribusiness is the industry, enterprises, and the field of study of value chains in agriculture and in the bio-economy, in which case it is also called bio-business or bio-enterprise. The primary goal of agribusiness is to maximize profit while sustainably satisfying the needs of consumers for products related to natural resources such as biotechnology, farms, food, forestry, fisheries, fuel, and fiber — usually with the exclusion of non-renewable resources such as mining. Studies of business growth and performance in farming have found successful agricultural businesses are cost-efficient internally and operate in favorable economic, political, and physical-organic environments. They are able to expand and make profits, improve the productivity of land, labor, and capital, and keep their costs down to ensure market price competitiveness. Agribusiness is not limited to farming. It encompasses a broader spectrum through the agribusiness system which includes input supplie ...

Prescribed Burning
A controlled or prescribed burn, also known as hazard reduction burning, backfire, swailing, or a burn-off, is a fire set intentionally for purposes of forest management, farming, prairie restoration or greenhouse gas abatement. A controlled burn may also refer to the intentional burning of slash and fuels through burn piles. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Hazard reduction or controlled burning is conducted during the cooler months to reduce fuel buildup and decrease the likelihood of serious hotter fires. Controlled burning stimulates the germination of some desirable forest trees, and reveals soil mineral layers which increases seedling vitality, thus renewing the forest. Some cones, such as those of lodgepole pine and sequoia, are pyriscent, as well as many chaparral shrubs, meaning they require heat from fire to open cones to disperse seeds. In industrialized countries, controlled burning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific Southwest Research Station
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Research Natural Area
Research Natural Area is a designation for certain protected areas in the United States. Research Natural Areas (RNAs) are part of a nationwide network of ecological areas set aside for both research and education. The network includes areas managed by many Federal agencies. The United States Forest Service and other agencies establish these areas to typify certain types of important forest, shrubland, grassland, aquatic, geological, alpine, or similar environments that have unique characteristics of scientific interest. The areas "contain important ecological and scientific values and are managed for minimum human disturbance". The first RNA was established on the Coronado National Forest in Arizona in 1927. The Bureau of Land Management is another agency that designates and manages Research Natural Areas. According to the Bureau of Land Management, the objectives of the RNA program are "(1) To preserve examples of all significant natural ecosystems for comparison with those inf ...
