Mangroves protected villages and reduced death toll during Indian super cyclone. The world coastal wetland lost more than 50% of its area in the 20th century, largely before their great value, such as wave attenuation, erosion control, biodiversity support, and carbon sequestration, was fully recognized. In part, this has been a result of natural evolutionary processes, but human activities, such as dredging wetlands for canals or draining and filling for agriculture, grazing, or development, share a large part of the responsibility for marsh habitat alteration and destruction. How much wetland has the world lost? Res. Wetlands under threat Besides filling them in or damming them, humans have also damaged or destroyed wetlands by planting invasive alien species around them, draining them by piping the water out to sea, or directing filthy stormwater from cities towards them. The amount of dryland within a few feet above the wetlands is much less than the area of wetlands that would be lost if sea level rises a few feet. 30 0 obj <> endobj Educating and organizing your community to enact and/or enforce an ordinance is another way of stopping wetland destruction. 0000001613 00000 n Geology. <<7B56AB1413FEA741B02CDCD02B0E9BE4>]>> Division of labour in rhizomatous species: comparative performance of native and invasive species in the tidal marshes of the Yangtze River estuary, China.

Dynamic response of marshes to perturbations in suspended sediment concentrations and rates of relative sea level rise. Deforestation far from shore can cause erosion that enters the water and deposits silt into the shallow marine waters, blocking the sunlight that coral reefs need to survive. For example, the average net primary productivity of mangroves is as high as that of the tropical rain forest (2.2 kgm, As key habitats for many terrestrial and marine species, vegetated zones and tidal creeks provide diverse shelter and food sources for a large variety of wild animals, resulting in high biodiversity and unique food webs.

Destruction of wetlands is a systemic problem that calls for cooperative planning among communities, nonprofit organizations, governments, and industry. Available from. Therefore, caring for wetlands is caring for biodiversity. Improper land use has led to the loss and destruction of millions of acre of natural environments across the globe. An estimated 95 percent of these wetlands are freshwater; the rest are marine or estuarine.1 Wetland extent can be affected by a variety of natural stressors, such as erosion, land subsidence, droughts, sea level change, and storms. Their presence ensures shelter and food for hundreds of fish, birds, invertebrates, amphibians, and mammals. Another type of habitat destruction is habitat degradation.
