Chapter 1 -Introduction and Executive Summaries
Chapter 2 -Biophysical Environments of the Basin: Contains multi-scale descriptions of the geologic, geoclimatic, climatic, potential vegetation, soils and hydrologic systems organization of the Basin. The maps and descriptions are based on landscape components that do not display high temporal variability. They often comprise the basis for delineation of environmental constraints for ecological pattern analysis. Regional, subregional and landscape scales of biophysical environment maps were developed.


Chapter 3 -Landscape Dynamics of the Basin: Addresses the dynamics of landscapes. The effects of roads and related land uses, introduction of exotics, land conversion, fire exclusion, and other factors on different vegetation communities are evaluated. Ecological integrity which was considered to be the ability of landscapes to renew themselves considering their paleoecological, historical, current and future biophysical potentials was also evaluated.


Chapter 4 -Broadscale Assessment of Aquatic Species and Habitats: The assessment of aquatic resources was directed along four primary themes. The geophysical and biological settings that define the natural potential of the Basin to provide for aquatic resources was characterized. Anthropogenic factors that affect aquatic habitats and species with special emphasis on effects of Federal land management were identified. The current condition of aquatic habitats and species were assessed. This information was synthesized to provide a regional context for Federal management strategies to protect and restore aquatic and riparian habitats.
Chapter 5 -Terrestrial Ecology of the Basin: Provides an ecosystem context for management and restoration of habitats and environments for terrestrial species and communities. A classification system for environmental correlates and ecological functions of species is provided, and functional groups of species are identified based on their ecological roles. Selection of bioindicators for monitoring environmental changes and for assessing problems of grassland deterioration are discussed and possible actions for mitigation and restoration are examined.


Chapter 6 -Economic Assessment of the Basin: Addresses the production of ecosystem goods, functions and conditions that society wants (economic efficiency), whose distribution of benefits is according to societal wishes (equity), and without adversely affecting economic activity. The economic issues related to fish, minerals, range, recreation and timber are characterized.
Chapter 7 -Social Assessment of the Basin: Documents the many types of human-environment interactions to provide a better understanding of the social, cultural and institutional context within which major ecosystem management policy questions can be addressed. A variety of interactions between people and the environment in the Basin are described.
Chapter 8 -Information System Development and Documentation: Provides a broad overview of the data, databases, and models employed by the ICBEMP and includes general recommendations for information management.

PNW-GTR-553:�� Bunting, Stephen C; Kingery, James L.; Hemstrom, Miles A.;Schroeder, M.A.; Gravenmier, R.A. and W.J. Hann.(2002) Altered rangeland ecosystems in the interior Columbia basin. 


A workshop was held to address specific questions related to altered rangeland ecosystems within the interior Columbia basin. Focus was primarily on public lands administered by the Forest Service and Bureau of Land Management. Altered ecosystems were considered to be those where human induced or natural disturbances are of sufficient magnitude to affect ecosystem processes, causing long-term loss or displacement of native community types and loss of productivity, making it difficult or impossible to restore these ecosystems to historical conditions. ��This document summarizes the types of potential vegetation types that are degraded, major causes for degradation, and potential restoration responses.

Current range distribution maps are presented for 14 invertebrate, 26 amphibian, 26 reptile, 339 bird, and 125 mammal species and selected subspecies (530 total taxa) of the interior Columbia River basin and northern portions of the Klamath and Great Basins in the United States. Also presented are maps of historical ranges of 3 bird and 10 mammal species, and 6 maps of natural areas designated by federal agencies and other organizations. The species range maps were derived from a variety of publications and from expert review and unpublished data, and thus differ in degree of accuracy and resolution.
