Wetlands cover less than one percent of Nevada but are some of the most economically and ecologically valuable lands in the State.
Benefits of wetlands include flood attenuation, bank stabilization, water-quality improvement, and fish and wildlife habitat. Desert wetlands include marshes in playa lakes, non-vegetated playas, and riparian wetlands; mountain wetlands include fens and other wetlands that form in small glacial lakes. More than one-half of Nevada’s original wetlands have been lost, primarily due to conversion of wetlands to cropland and diversion of water for agricultural and urban use; many others have been seriously degraded by human activities. Some wetlands have been created by mine dewatering and sewage treatment.
Nevada List of Threatened and Endangered Species
The Convention on Wetlands (Ramsar, Iran, 1971) — called the “Ramsar Convention” — is an intergovernmental treaty that embodies the commitments of its member countries to maintain the ecological character of their Wetlands of International Importance and to plan for the “wise use”, or sustainable use, of all of the wetlands in their territories. The Convention on Wetlands came into force for the USA on 18 April 1987. The USA presently has 35 sites designated as Wetlands of International Importance, with a surface area of 1,827,196 hectares.
Ash Meadows National Wildlife Refuge. 18/12/86; Nevada; 9,509 ha; 36º25’N 116º20’W. National Wildlife Refuge. A unique oasis ecosystem of streams, pools, and wet meadows, formed around springs supplying a tributary of the Amargosa River. The site lies within an area exhibiting the greatest biological endemism in the USA. Four species of endangered endemic fish and an endemic aquatic insect are present, and several of the region’s plants are listed as threatened or endangered endemic species. Other endemics include several molluscs and one mammal. The water table is close to the surface and soils are mostly saline, often with a well-developed salt crust. Human activities have consisted of agriculture, irrigation, peat and clay mining, and off-road vehicle use. Ramsar site no. 347. Most recent RIS information: 1992.
