内容简介

Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with "Wetland Indicators" - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of 'Wetland Indicators'. Practicing - and aspiring - wetland delineators alike will appreciate "Wetland Indicators"' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors.This work: shows 55 color plates, documenting wetland indicators throughout the nation - with more than 34 soil plates and aerial photos; illustrates other wetland properties with more than 50 figures; and, provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation. Contents include: Wetland Definitions; Wetland Concepts for Identification and Delineation; Plant Indicators of Wetlands and Their Characteristics; Vegetation Sampling and Analysis for Wetlands; Soil Indicators of Wetlands; Wetland Identification and Boundary Delineation Methods; Problem Wetlands and Field Situations for Delineation; Wetland Classification; Wetlands of the United States: An Introduction, With Emphasis on Their Plant Communities; and, Wetland Mapping and Photointerpretation.
