As part of the Willamette Basin Geographic Initiative Program, the Environmental Protection Agency (EPA) funded The Nature Conservancy of Oregon to inventory, classify, and map native wetland and riparian plant communities and their threatened biota in the Willamette Valley. Between October 1994 and September 1996, we evaluated 172 wetland and...
Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Kongsberg Simrad EM-300 operating at 30 kHz. The data set collected includes both topographic...
The purpose of this watershed assessment is to provide an inventory and characterization of
watershed conditions in the Wilson River watershed and to provide recommendations that
address the issues of water quality, fisheries and fish habitat, and watershed hydrology.
In this watershed assessment, the authors of the report summarized current conditions and data gaps within the Necanicum River watershed to help to identify how current and past resource management is impacting aquatic resources.
Ecoregions are regions of relative homogeneity with respect to specific
ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing
awareness that effective management of environmental resources must be undertaken
with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial
framework for assessing, managing, and monitoring ecosystems that...
The purpose of this work is to broaden the theoretical foundations of interpolation of spatial data, by showing how ideas and methods from information theory and signal processing are applicable to the the work of geographers. Attention is drawn to the distinction between what we study and how we represent...
In this thesis I argue that Alice Munro’s work takes part in an ongoing feminist discourse that examines alterations in male and female gender relations, as they have been represented in domestic fiction by women writers since the late nineteenth century. I analyze two short stories written by Munro: “Meneseteung,”...
Conventional soil maps represent a valuable source of information about soil
characteristics, however they are subjective, very expensive, and time-consuming to
prepare. Also, they do not include explicit information about the conceptual mental
model used in developing them nor information about their accuracy, in addition to the
error associated with...
"This report is organized as follows. First, the
objectives and methods used are outlined. Background
information follows, including what is known about the
extent, past alterations, and condition of wetlands in
Oregon today; the status of wetland restoration in the U.S.
and in Oregon; definitions of important terms; the functions...
