Ecological regionalization is a form of spatial
classification, where boundaries are drawn around areas
relatively homogeneous in landscape characteristics. In the
delineation of ecological regions, or ecoregions, the process
includes the analysis of ecosystem structure and function.
Ecoregions have been developed at national and state scales
for research and resource...
present a unique modeling approach to investigate the
potential impacts of future land use alternatives on amphibian population
dynamics in two agricultural watersheds in central Iowa. An individual-based
spatially explicit population was used to predict the consequences of alternative
landscape design and management for populations of four amphibian species. The...
Instream flow protection in western prior appropriation states is a relatively new phenomenon.
Integrating instream flow protection measures with the older water law has been accomplished with varying
degrees of success. Idaho relies on appropriation of unappropriated water by the Idaho Water Resource Board
for protection of instream flows. Idaho's...
Management of national forests evokes controversy about the
allocation of limited resources among competing uses. A Land and Resource
Management Plan (Forest Plan) has been prepared for the Payette National
Forest. The Forest Plan describes resource management practices and the levels
of resource production at which the Forest would be...
This research was designed to search for regularities in
the spatial pattern resulting from government designation of
protected areas for conservation purposes on the African continent.
Four countries were used to test for a relationship between
protected areas and vegetation types and also whether colonial
background had an impact on...
Compromises required for the passage of the Wilderness
Act (1964) created inherent conflicts in the designation and administration
of wilderness areas. Subsequent legislation helped to more
firmly interpret and define the Act. Attendant policy changes suggest
a trend to increase the recreational and economic utility of wilderness.
Policy changes also...
This paper includes the proposed "Willamette River Greenway"
section of the Linn County Comprehensive Plan and "Criteria
and Standards for Greenway Development Permits," the proposed
implementing ordinance.
Oyster production in the United States has declined from a leading
nineteenth century fishery to a minor, failing industry. Oystermen must now
depend on a diminished resource in an environment of competing and conflicting
coastal uses. One of the most important influences on the industry's welfare
is the sanitation of...
This project explores the impact of land use decisions on dune processes at the
Oregon National Guard's Camp Rilea. located on the north coast of Oregon. It
used a combined analysis of historical and modern data sources to assess the
impact of land use practices. Historical sources including the journals...
Ragay Gulf and Burias Pass are among the traditional fishing grounds of the
country being considered by the government for an integrated approach to fishery
management (Smith, et al., 1980; Samson, et al., 1977, World Bank, 1976). The
Department of Marine Fisheries, College of Fisheries, University of the Philippines in...
