A process to distinguish between primary and
secondary resource lands is currently a concern of state and local
land-use agencies in Oregon. Two approaches for identifying
Secondary Resource Lands have been developed. The Land
Conservation and Development (LCDC) staff, in conjunction with the
County Planning Directors Association, have developed one...
The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...
The direction and scope of this research paper follows closely an earlier
sampling study conducted by Behm and Pease (1985). In this pilot project, the
authors employed a two-stage random sampling method in determining land use
estimates. Anderson's land use classification system was used for data
categorization (Table 1). The...
Since 1983, the Oregon legislature and the Land Conservation
and Development Commission have been attempting to develop a
process whereby secondary resource lands can be identified and
designated. The most recent attempt at developing a secondary
lands model was completed in 1990 and was tested in six Oregon
Counties. Planners...
Marginal agricultural land is currently a focus of concern for
public land use agencies in Oregon. Two approaches for evaluating marginal
agricultural lands are the Land Evaluation and Site Assessment (LESA) model
of the U.S. Soil Conservation Service, and the marginal lands criteria of
the 1983 Oregon Legislature's Senate Bill...
A Geographic Information System (GIS) can be a powerful tool for solving land use planning
problems. The synthesis, analysis, and depiction of spatial data make it a valuable tool for land use
planners. A primary issue with GIS is the cost and time required to develop a functional system.
One...
Marginal agricultural and forest lands are currently a focus of concern for public land use agencies in Oregon. Two alternatives for evaluating marginal agricultural lands are the Land Evaluation and Site Assessment (LESA) model of the U.S. Soil Conservation Service and the marginal lands criteria of the 1983 Oregon Legislature's...
Riparian areas contribute to numerous ecological-maintenance functions and so are
often the focus of protection efforts by land and resource management agencies. The riparian
land-use regulations of one jurisdiction, Lane County, Oregon, are assessed for effectiveness in
protecting ecological functions. Evaluation of the current condition of five elements of riparian...
The Late Spring Secondary Precipitation Maximum in the
Interior Pacific Northwest results from a complex system of climatic
controls. The Secondary Maximum is most strongly developed over the
high plateau of Oregon immediately in the lee of the Cascade
Mountains. Local topographic
organization exerts strong control
over the magnitude and...
