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:

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:

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. For more information, contact: Metropolitan
Conservation Alliance, 68 Purchase St., 3rd floor, Rye, NY 10580,

5. 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
