Written for environmental consultants and students enrolled in Wetlands Delineation courses, this second edition reference provides a comprehensive foundation for wetland identification, classification, delineation, and mapping. It contains material that has been updated and new information that has been discovered since its original 1999 publication, and incorporates analysis of the 2010 Army Corps of Engineers Wetlands Delineation Manual. It reviews current and past delineation practices for perspective on advances in the field. It describes international classifications (Ramsar) as well as those from some individual countries. While pictures are provided within the text, a supplementary website provides more photos, upon purchase.
Seems to be intended as a textbook for people who're going to delineate wetlands for government agencies like the Army Corps of Engineers. It gives lots of insight into both the definitions and the indicators you use in the field. Can be dense and dry sometimes, but the author lets his experience show (and it goes back about to the beginning of widespread wetland regulation in the U.S.). Delineators decide whether land is wetland by checking vegetation and soil to see if they are typical for flooded or saturated places, and looking for actual water or signs of it. Vegetation is the most traditional indicator, soil is also helpful but only recently studied, and water is the least reliable indicator because of seasonal and other changes.
