Highland Cattle on the Grazing Marsh at London Wetland Centre. Conservation grazing or targeted grazing [1] is the use of semi-feral or domesticated grazing livestock to maintain and increase the biodiversity of natural or semi-natural grasslands, heathlands, wood pasture, wetlands and many other habitats.
A wetland (aerial view) 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.
Major remaining wetlands of the United States. Red dots indicate critical wetlands. The U.S. Fish and Wildlife Service's National Wetlands Inventory (NWI) produces and provides information on the characteristics, extent, and status of U.S. wetlands and deepwater habitats and other wildlife habitats. The NWI also produces periodic reports on the ...
This translates to about 426 gC/m 2 /yr for land production (excluding areas with permanent ice cover), and 140 gC/m 2 /yr for the oceans. However, there is a much more significant difference in standing stocks —while accounting for almost half of total annual production, oceanic autotrophs account for only about 0.2% of the total biomass.
Photo of Baugh Creek, Idaho, illustrates how a string of beaver ponds in a barren, post-wildfire landscape, serves as wildlife refugia and potentially as firebreaks.

In such circumstances where flooding does occur, swamps absorb and use the excess water within the wetland, preventing it from traveling and flooding surrounding areas. [2] Dense vegetation within the swamp also provides soil stability to the land, holding soils and sediment in place whilst preventing erosion and land loss.
In areas where the habitat is relatively undisturbed, halting further habitat destruction may be enough. [3] In areas where habitat destruction is more extreme (fragmentation or patch loss), restoration ecology may be needed. [60] Education of the general public is possibly the best way to prevent further human habitat destruction. [61]
Wetlands are areas of land submerged in water near both terrestrial and aquatic systems. They are highly diverse and are classified by the United States Fish and Wildlife Service into five categories: “The term wetland includes a variety of areas that fall into one of five categories: (1) areas with hydrophytes and hydric soils, such as those commonly known as marshes, swamps, and bogs; (2 ...
