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. Features 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 Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation Contents 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 Wetland Mapping and Photointerpretation

A multidisciplinary study of pre-Columbian South America—centering on the psychoactive plant genus Anadenanthera As cultures formed and evolved in pre-Columbian South America, Anadenanthera became one of the most widely used shamanic inebriants. Anadenanthera: Visionary Plant of Ancient South America is more than a comprehensive reference on shamanic visionary substances; it is a useful tool for archeologists and pre-Columbian art historians. This thorough book examines the ritual and cultural use of Anadenanthera from prehistory to the present, along with its botany, chemistry, pharmacology, anthropology, and archeology. The earliest evidence for the use of psychoactive plants in South America is provided by remains of seeds and pods recovered from archeological sites four millennia old. Various preparations were derived from it with the intent of being a shamanic inebriant. Inhaled through the nose, smoked in pipes or as cigars, and prepared in fermented drinks, Anadenanthera served a central role in the cultural development of indigenous societies in South America. Anadenanthera: Visionary Plant of Ancient South America explores the full spectrum of information gleaned from research, covering numerous archeological sites in the Andean region, as well as discussing Amazonian shamanic rituals and lore. Analyses of the artistic expressions within the decorations of associated ceremonial paraphernalia such as ritual snuffing tubes and snuff trays are included. The text is richly illustrated with photographs and images of decorated ritual implements, and provides a comprehensive bibliography. Anadenanthera: Visionary Plant of Ancient South America explores: botanical aspects, taxonomy, and geographical distribution of Anadenanthera ethnographical, historical, and traditional aspects of Anadenanthera use chemical and pharmacological investigations of the genus and the various visionary preparations derived from it—with emphasis on the biologically active constituents theories of the mechanisms of action of the active tryptamines and carboline alkaloids comparisons of wood anatomy, morphology, and percentage of alkaloid content evaluation of stylistic and iconographic traits Anadenanthera: Visionary Plant of Ancient South America is a thorough, useful resource for archeologists, anthropologists, chemists, researchers, pre-Columbian art historians, and any layperson interested in pre-Columbian art, archeology, or visionary plants.
