Restoration Ecology
Restoration ecology is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human interruption and action. Effective restoration requires an explicit goal or policy, preferably an unambiguous one that is articulated, accepted, and codified. Restoration goals reflect societal choices from among competing policy priorities, but extracting such goals is typically contentious and politically challenging. Natural ecosystems provide ecosystem services in the form of resources such as food, fuel, and timber; the purification of air and water; the detoxification and decomposition of wastes; the regulation of climate; the regeneration of soil fertility; and the pollination of crops. These ecosystem processes have been estimated to be worth trillions of dollars annually. There is consensus in the scientific community that the current envi ...

Discovery Cube Los Angeles
The Discovery Cube Orange County, formerly known as the Discovery Science Center and the Taco Bell Discovery Science Center, is a science museum in Santa Ana, California, with more than 100 hands-on science exhibits designed to spark children's natural curiosity. Designed by the architect firm Arquitectonica with structural engineers Carl Johnson and Svend Nielsen, it has become a visual landmark due to its ten-story solar array cube that stands over Interstate 5. History In 1984, the Boards of the Exploratory Learning Center and the Experience Center joined to form the Discovery Museum of Orange County with the dual goals of teaching children what life was like in Orange County in the 1900s and creating a world-class science center. A funding feasibility study in 1989 indicated that county leaders would support the project. In the mid-1990s, prior to construction, a smaller "beta" version of the science center called Launch Pad operated in South Coast Plaza. The current fa ...

Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yucca In Bloom At Big Tujunga Canyon In Sunland
''Yucca'' is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava (''Manihot esculenta''). Consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, ''yuca''. The Aztecs living in Mexico since before the Spanish arrival, in Nahuatl, call the local yucca species (''Yucca gigantea'') , which gave the Spanish . is also used for ''Yucca filifera''. Distribution The natural distribution range of the genus ''Yucca'' (49 species and 24 subspecies) covers a vast area of the Americas.

Groundwater Recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface. Processes Water is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge may be impeded somewhat by human activities including paving, development, or logging. These activities can result in loss of topsoil resulting in reduced water infiltration, enhanced surface runoff and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
