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.
