Ž . A wide range of local, state, federal, and private programs are available to support the national USA policy of wetland ‘No Net Loss’. Implementation of programs, however, has resulted in the continued loss of natural wetlands on the premise that restored or created wetlands will replace the functions and values lost by destruction of natural wetlands. What are the ecological implications a...

outdoor recreation refers to various recreational activities, closely associated with natural environments. wetlands are the ecosystems which provide numerous goods and services with economic values, not only to the local population living in their periphery but also to communities living outside wetland. furthermore, wetlands provide some opportunities and amenities for human society’s well-be...

Conservation and wise use of wetlands has been given priority world over. India harbours diverse types of wetlands. This study highlights the findings of the national-level inventory and assessment of wetlands carried out using RESOURCESAT-1 LISS-III data of 2006–07 at 1 : 50,000 scale. A hierarchical system comprising 19 classes based on Ramsar definition has been used to classify the wetlands...

JENNIFER LEA BISHOP. Mapping the Boulder City Wetlands Using a Global Positioning System (GPS) and a Geographic Information System (GIS) (Under the Direction of Krystyna A. Stave and Shawn Gerstenberger) The Boulder City Wetlands is a constructed wetlands park located in Boulder City, Nevada, approximately 23 miles southeast of Las Vegas, Nevada. Currently, a baseline study of water quality is ...

Wetlands are an important natural resource in the biosphere. Traditional terms used to describe wetlands are marshes, bogs, and swamps. Early European settlers considered these areas as wastelands and did not appreciate their values. For a number of years, many of these areas were drained and used as farmland, since these lands were found to be productive. Over a 200-yr time span (1780-1980), t...

One measure used in Sweden to mitigate eutrophication of waters is the construction of small wetlands (free water surface wetland for phosphorus retention [P wetlands]) to trap particulate phosphorus (PP) transported in ditches and streams. This study evaluated P retention dynamics in a newly constructed P wetland serving a 26-ha agricultural catchment with clay soil. Flow-proportional composit...

We studied patterns in avian cholera mortality, the presence of Pasteurella multocida in the water or sediment, and water chemistry characteristics in 10 wetlands at the Sacramento National Wildlife Refuge Complex (California, USA), an area of recurrent avian cholera epizootics, during the winters of 1997 and 1998. Avian cholera outbreaks (>or=50 dead birds) occurred on two wetlands during the ...

Anthropogenic disturbance of landscapes surrounding wetlands is considered a factor in local and global amphibian declines. Few data exist on the effects of agricultural cultivation of wetland watersheds on amphibians, and results from previous studies are contradictory. Our objective was to test the effects of general anthropogenic land use (cultivation vs. grassland) on the demographics of se...

Maintaining Biodiversity through Semi-Extensive Grazing: Palo Verde National Park, Costa Rica 3. Integrated Grazing Management in Wetlands: New Approaches 3.1. Combining Biodiversity Conservation with Livestock Reari...

We compared plant diversity in four restored and four natural wetlands in the glaciated interior plains to evaluate how quickly plant biodiversity develops following cessation of agriculture and reintroduction of wetland hydrology. After approximately ten years, restored wetlands had plot and site richness comparable to natural wetlands; 6.2 + 0.5 species per plot and 33.8 + 2.3 species per sit...
