Forwarded by Jane Clark at [log in to unmask] -- some interesting topics. A number of technical references about wetlands have come to our attention in the past few months. They are listed below. 1. The Impact of Urban Development on Wetlands 2. Simple Indicators May be Adequate to Describe Landscape Influences 3. Landscape Context, Hydrology, and Exotic Species as Factors Affecting Wetland Amphibian Communities in the Pacific Northwest 4. Thousand Acre Difference 5. Stormwater Strategies from NRDC 1. Long term monitoring research in Oregon studied 45 natural wetlands and 51 mitigation wetlands. The researcher says, "Our results indicate that urbanization and mitigation practices are major stressors that are changing the structure and ecological character of the wetland resource in the Portland [OR} metropolitan area." For more specifics, check out: http://www.epa.gov/wed/pages/news/jan.htm 2. Research in the Prairie Pothole Region of North Dakota suggests that variation in wetland bird responses could be linked to two measure of the landscape that can be identified through remote sensing -- the abundance of wetlands and the proportion of cropland. For more details, check out: http://www.epa.gov/wed/pages/news/jan.htm 3. In the Pacific Northwest, replacement of seasonal wetlands with permanent wetlands through mitigation projects and urbanization is changing the availability and connectedness of wetlands. At the same time, native amphibian populations are declining. This research looks at these two issues. For more info, look at: http://www.epa.gov/naaujydh/pages/projects/reb/exoticspecies.htm 4. In New York, the Metropolitan Conservation Alliance performed studies that indicate that natural areas less than 1,000 acres show a drop of species diversity, especially amphibians. A discussion of land-use planning strategies was addressed.

The Natural Resources Defense Council (NRDC) has completed a study on stormwater runoff pollution. There is an extensive report at http://www.nrdc.org/water/pollution/storm/stoinx.asp. NRDC is also conducting outreach around stormwater pollution and solutions and will make presentations at workshops on this topic. A short summary of the report and recommendations for local action and information about the stormwater outreach program can be obtained by asking us at wetlands.org or contacting NRDC: George Aponte Clarke (212)727-4413 or [log in to unmask] - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - For SC email list T-and-C, send: GET TERMS-AND-CONDITIONS.CURRENT to [log in to unmask]
