Book excerpt: Ecological units are described at the subsection level of the Forest Service National Hierarchical Framework of Ecological Units. A total of 91 subsections are delineated on the 1996 map 'Ecological Units of the Northern Region: Subsections,' based on physical and biological criteria. This document consists of descriptions of the climate, geomorphology, geology, vegetation, and soils that characterize each subsection. Included is information on sources of natural disturbances, current land use, and ecological relationships of the major components.

Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

This book was released on 1996 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a hierarchical framework for classifying and mapping aquatic ecological units based on biophysical factors that display low temporal variability at a given map scale, and strongly affect the types of ecosystem patterns and processes that occur in aquatic systems. It addresses the 3 major aquatic systems that occur widely: the riverine system of streams and rivers; the lacustrine system of lakes and open-water wetlands; and the ground-water system of aquifers. Hydrogeomorphic criteria are also proposed to refine existing wetlands classifications. Ensures a consistent framework in the classifying and mapping of aquatic systems. Charts and tables.
