Wetland conservation. Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
Effects on stream flows and water quality. Beaver ponds increase stream flows in seasonally dry streams by storing run-off in the rainy season, which raises groundwater tables via percolation from beaver ponds. In a recent study using 12 serial aerial photo mosaics from 1948 to 2002, the impact of the return of beavers on openwater area in east ...
Habitat destruction. Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation. Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or ...
Pictures of the destruction in the town of Okeechobee in 1928. The City of Miami responded to the hurricane by downplaying its effects and turning down aid. The Miami Herald declared two weeks after the storm that almost everything in the city had returned to normal. The governor supported the efforts to minimize the appearance of the ...
An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". [ 1 ] Sometimes a precise legal definition of a wetland is required.
Restoration of the Everglades. A portion of the C-38 canal, finished in 1971, now backfilled to restore the Kissimmee River floodplain to a more natural state. An ongoing effort to remedy damage inflicted during the 20th century on the Everglades, a region of tropical wetlands in southern Florida, is the most expensive and comprehensive ...
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
No net loss is a mitigation policy goal aiming to prevent and offset the destruction or degradation of wetlands. Under this bi-partisan policy, wetlands currently in existence are to be conserved if possible. No net loss is achieved through a coordinated effort of: [7] wetlands protection. creation of new wetlands.
