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.
Riparian zone. A riparian area is the transition from the aquatic area to the upland area. Vegetation is expected to change from species adapted to wetter sites near the channel to species adapted to drier sites in the upland, with a mixture of species occurring in between. In this example, an assessment of riparian function would consider the ...
A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a ...
Many species of frogs live in wetlands, while others visit them each year to lay eggs. Snapping turtles are one of the many kinds of turtles found in wetlands. Many species of fish are highly dependent on wetland ecosystems. [44] [45] Seventy-five percent of the United States' commercial fish and shellfish stocks depend solely on estuaries to ...
And even with the current focus on wetland conservation, the US is losing about 60,000 acres (240 km 2) of wetlands per year (as of 2004). [2] However, from 1998 to 2004 the United States managed a net gain of 191,750 acres (776.0 km 2) of wetlands (mostly freshwater). [2] The past several decades have seen an increasing number of laws and ...
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. [1][2] Mangrove forests grow mainly at tropical and subtropical latitudes because mangrove trees cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which grow ...
Carex, the true sedges, contains over 2,000 species, primarily found in wetland environments. Eleocharis, the spikerushes. Scirpus, bulrushes. Sphagnum is a genus of moss that is found primarily in the Northern Hemisphere, as well as in some areas of South America, New Zealand and Tasmania. Sphagnum moss is notable because it forms peat.
Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of limnology. This field seeks to understand the relationships between living organisms in their physical environment. These physical environments may include rivers, lakes, streams, ponds, reservoirs, or wetlands. [1]
