Wetlands are defined as areas of land that are saturated with water year round and take on characteristics of a distinct ecosystem. In China, northwest of Hong Kong, lies the Mai Po Nature Reserve (22°30′ N and 114°02 E′) (Cheung and Wong 2006). The entire Mai Po Nature Reserve (MPNR) encompasses about 2,700 hectares or about 6700 acres. It is home to some of the world’s most endangered water birds. The wetlands support a large number of migratory water birds every year. During the spring thousands of migratory shorebirds stop to rest before continuing north toward their breeding grounds. They return to MPNR during autumn as they fly south toward their traditional wintering ground. MPNR also hosts over 400 different species of insects, 90 species of invertebrates, and 50 different butterfly species (Cheung and Wong 2006).
MPNR is also a huge part of Hong Kong’s freshwater fish farming. Ponds were created (local name gei wai) during the 1920’s and 1960’s to harvest shrimp and fish. Gei wais are great examples showing that wetlands can be managed sustainably (Wong 2003). Placing dike...
The first mitigation banking guidance was released in 1995 by the EPA and Corps of Engineers. The most recent wetland mitigation banking guidance was released in 2008. The idea behind both wetland mitigation banking and conservation banking is to provide compensation for unavoidable impacts to resources prior to the environmental impact taking place (FWS, 2003). Based on the rules set forth in section 10 of the Rivers and Harbors Act and section 404 of the Clean Water Act, wetland impacts are reduced by using the following sequence of steps: avoiding impacts, minimizing impacts, and as a last resort, mitigating for impacts. Although the Corps has enforced a mitigation policy to reg...
Perhaps the most devastating disregard of the Fraser Valley’s biodiversity was the draining of Sumas Lake to create farmland, resulting in the loss of habitat and the extirpation of endemic species. As it was originally intended to be, the Fraser Valley was a “perhaps unparalleled ecosystem” (Rosenau, p. 55), with bountiful wetlands and remarkable biodiversity. The European settlers 150 years ago considered it to be “wasteland” (Thom, p. 172), certainly uninhabitable and a breeding ground for mosquitoes, so the most logical thing to do would be to drain the body of water once known as Sumas Lake...
The Badu Wetlands are located within the Bicentennial Park which is located in the Parramatta River Basin approximately 12km west of the CBD. It receives slightly less rainfall and higher average temperatures than that of the CBD (central business district). The latitude of Bicentennial Park is 3350’ and the longitude is 15304’ with an altitude of 0-10 meters above seas level (m.a.s.l )The average temperature of the park is a warm temperate eastern marine. The size of the park is 100 hectares with the wetland size being 58 hectares, showing that the wetlands cover more than half of the park.
Every day many species are slowly becoming either endangered or extinct and recently an endangered bird species called piping plovers, started nesting on Revere Beach. What would seem as a miraculous discovery, many are averse to their new inhabitants on the beach. Many Revere residents are complaining because the piping plovers now occupy parts of “their” beach. But in the article “Revere Beach should welcome the piping plover” The Editorial Board believes that the presence of the piping plover could be greatly beneficial to the city of Revere and I certainly agree. What led me to select this particular article is my concern for the many endangered species in the world like the piping plover. Human hands have led many species to become endangered
DUI’s vision is, “…wetlands sufficient to fill the skies with waterfowl today, tomorrow and forever.” The site’s main focus stays true to DUI’s vision; protecting important waterfow...
Piping plovers are small shorebirds that usually lives on sandy beach and is considered to be endangered. It has a pale color that blend perfectly with dry beach sand. During the spring and summer, it appears to have a single black neckband and a narrow black band across its forehead. The plover’s bills and legs are yellowish but their bills have a black tip. During their flight its rump is white in color. The sexes appear similar, in both their size and color. During the winter, their legs and bill gets darker. Piping plovers are seen in small flocks or singularly.
The Everglades, classified as a wetland or a "transition zone" can support plant and animal life unlike any other place. Wetlands are an important resource for endangered species and "that more than one third of the United States' threatened and endangered species live only in wetlands." Says Elaine Mao, the author of Wetlands and Habitat Loss. People have started to notice the importance and the role of wetlands like the Everglades and how they are valuable and essential for ecosystems to live. Wetlands provide so many kinds of plants, mammals, reptiles, birds, and
By conserving the ecosystem, the animal population will incline. Recent reports of record duck numbers throughout much of their continent-wide breeding range is proof that to manage wildlife you need to manage their ecosystems. Wet weather, combined with abundant nesting cover provided by the federal Conservation Reserve Program, has shown that wetland and grassland ecosystems are what make or break duck populations. The same is true for all other species, game and non-game. R. Holmes.
The Hudson Plains ecozone, in northern Ontario and parts of Manitoba and Quebec, is an area of wetlands. The climate is generally cool. The northern part of the ecozone is full of shrubs, but no trees, and areas farther south contain forests. Wet have vegetation such as moss and lichen and also some trees like willow, tamarack and black spruce. More northern, drier locations have vegetation consisting of many shrubs such as crowberry and blueberry. In the summer, the wetlands of the Hudson Plains attract millions of migratory birds, such as snow geese, Canada geese and king eider ducks. Mammals which can be found here include moose and black bear, but small mammals such as muskrats and weasels are more common.
Within the state of Colorado lies a well know national park, which is known for its breathtaking geologic features and history of ancient civilizations. This site of interest is known as Mesa Verde National Park. In the Spanish language, Mesa Verde means green table. This park serves a medium for the protection of the thousands of well-known archeological sites that lie within it. Many of these preserved sites served as a home for its inhabitants, the Ancestral Pueblo people, over a thousand years ago. It is estimated that this was most likely around AD 600 to about 1300.
...n, the Louisiana wetlands are an extremely valuable asset to the State of Louisiana and the United States. The continual loss of Louisiana wetlands has the potential to have an immensely negative effect on the economy at a state and national level. Over 2 million people live in the Louisiana coastal parishes (Field et al., 1991). The majority of people living on the Louisiana coast make their living from things that are directly related to the wetlands. The Louisiana wetlands make up the largest wetland community in America and is being lost at a rate greater than the other wetland communities in the country. The suggested strategies that are being taken into consideration could be helpful but it seems that the State of Louisiana is not as concerned as it should be given the future consequences and much like climate change coastal erosion is not being taken serious.
Globally coastal wetlands are disappearing at an alarming rate, the problem is most of society does not realize the value of these precious wetlands. Coastal wetlands provide an important role in the coastal ecosystem. “Coastal wetlands provide critical services such as absorbing energy from coastal storms, preserving shorelines, protecting human populations and infrastructure, supporting commercial seafood harvests, absorbing pollutants and serving as critical habitat for migratory bird populations”(Anonymous, 2011). Coastal wetlands are an economical asset as well as an environmental one.
Between 300 and 400 million people worldwide live in areas near wetlands and depend on them. Wetlands are mechanisms for treatment of wastewater are extremely efficient because they absorb chemicals and filter pollutants and sediments. Half the world's wetlands have disappeared due to urbanization and industrial development. The only way to achieve sustainable development and poverty reduction will be through better management of rivers and wetlands, and the land they drain and drain as well as through increased investment in them.
Legend has it that the White Mountains received their name from early sailing visitors to New England who saw the distant snow capped peaks in the distance as the sailed south along the coast.
