Hi Some years ago I sent a link for the Davis wetlands area (Yolo Bypass) [see below]. This month (March-April, 2011) there is an excellent article in the Audubon magazine titled Grains of Change (pages 64-71) showing pictures of the Yolo Bypass Wildlife area talking about rice production and long-billed curlews. "A system for mapping Riparian Areas in the Western United States" can be downloaded from the US Fish and Wildlife Service website
http://www.fws.gov/wetlands/ There is much information on the above website for wetlands, including wetlands mapper. The city of Davis, California has a '400 acre Davis wetlands project'. Anybody interested here is the link with updated information http://www.ci.davis.ca.us/pw/water/wetlands.cfm It is open free to the public - well worth a visit (in the winter it is sometimes closed due to flooding) Regards, from Ling Huang Chemistry Department Sacramento City College http://huangl.webs.com
