We investigated the influence of landscape and wetland characteristics on pond-breeding amphibian assemblages in south-central New Hampshire, a relatively low populated and heavily forested region of the northeastern United States. This allowed us to better understand landscape influences in less disturbed areas, and to determine critical landscape disturbance thresholds, above which amphibians...

F.1.1 Current Wetland Area and Rates of Loss The ability to estimate soil carbon pools and fluxes in North American wetlands is constrained by the national inventories (or lack thereof) for Canada, the United States, and Mexico (Davidson et al., 1999). The National Wetland Inventory (NWI) program of the United States has repeatedly sampled several thousand wetland sites using aerial photographs...

The Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS) initiated a two-year regional pilot survey in 2007 to develop, test, and validate tools and approaches to assess the condition of northern Gulf of Mexico (GOM) coastal wetlands. Sampling sites were selected from estuarine and palustrine wetland areas with herbaceous, forested, and shrub/scrub habitats delineated by the ...

the purpose of this study is estimate the protection value of gavkhony wetland ecosystem attributes with use of choice experiment approach and conditional logit model. data needed extracted from six different choice experiment questionnaires filled out by 500 random households in isfahan and varzane city. each questionnaire contained 72 hypothetical policies (options), 36 choice sets, 2442 obse...

Wetland resource management is an important task in the protection and utilization of wetlands. Given the environmental interests in these wetlands, there is urgent need for a centralized repository and mechanism to share geospatial data, information and maps of wetlands. Our objective is to develop an interactive WebGIS and geodatabase for wetlands providing mapping and data services. This pap...

Wetland is an integrated ecosystem which includes ecosystems such as hydrology, soil, vegetation, and biological environments. At present, the urbanization rate of China’s national economic development process rapidly increasing, by end 2021, resident population will be 64.72%. This paper analyzes hydrological effects urbanization, impact water resources, climate change, biodiversity on wetland...

As a national key protection and restoration project, ecological of Baiyangdian Wetland has an important significance for environmental management. the research area in Zaozhadian wetland, purification effect warm season cold aquatic plants was studied under different overflying water qualities. It provides theoretical experimental basis environment management wetlands. The results showed that ...
