WATER SCIENCE
Wetland identification, although theoretically straightforward,
is not cut and dry as a practice.
Despite the time and expense, it is an economic and environmental necessity.

PR ACTICAL HANDBOOK FOR
WETLAND IDENTIFICATION AND DELINEATION
The Def initive Guide to the Practice of Wetland Identification
The second edition of the bestselling Practical Handbook for Wetland Identification and Delineation
offers solutions to real-world problems in the scientific and regulatory aspects of wetlands. The
authors present characteristics and indicators of wetlands that are the focus of the jurisdictional IDENTIFICATIONWETLAND AND DELINEATION
issue, and discuss strategies and methods for making wetland identifications and delineations that
meet federal requirements.
What’s new in the Second Edition:
• Coverage of increased options for scientific evaluation of problematic areas
• More details on the definition of wetlands, description of their functions,
and delineation methods used to assess their extent
• Lay examination of legal questions, regulatory/permitting requirements,
statutes, and other guidance
• Information on the latest techniques for conducting wetland evaluations
• Exploration of advances in mapping, surveying, and remote sensing technologies
Although the most basic delineation methods and procedures have not changed since the first
edition, the availability and power of advanced mapping, remote sensing, and surveying technologies
have advanced the science. Low and higher altitude aerial imagery, geographic information system
(GIS) databases, easily accessible land cover maps, and fine resolution satellite data are just a few
of the resources available. Despite these advances, it is still difficult to find practical directions
on how to gather needed data in the literature.
