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 ...
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.
Introduction. 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.
Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution, climate change ...
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 ...
Pistia, a genus with one species that is native to tropical environments and has further extended its range as an introduced species. Phragmites is a genus of plants known as reeds. Pondweeds are a family of aquatic plant with a subcosmopolitan distribution. Sagittaria is a genus of plants known as arrowhead or katniss.
Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness[181] is the relative number of individuals of each species in a given area.
The Wetlands Geodatabase is one of the world's largest polygonal datasets (in the civilian sector). The information is increasingly popular and widely used to help identify, conserve, and restore wetland resources across the American landscape. During 2008, the number of website user requests for data exceeded 56.9 million.
