Populations of coastal cutthroat trout, Oncorhynchus clarki clarki, were sampled in 16 headwater streams from logged (20-30 and 40-60 years ago) and unlogged (stand age 125-150 years) basins. Basins logged 20-30 years ago supported the widest range of mean biomass of age 1+ or older cutthroat trout (g/m2) and the...
The product of my internship was a working draft of a land use and master plan
for the SPC to review. The draft is to be used for creating a more comprehensive land use
and zoning master plan. Attempts were made to incorporate input from federal, state,
and local governments,...
This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...
Coral reef ecosystems are the oceanic equivalent of tropical rainforests, in terms of biodiversity. The estimated 1,037,000 square kilometers worldwide of reef provide
habitat for over one million species of plants and animals (Hinrichsen, 1997). Coral reefs are important to the economy of coastal nations because of the fisheries and...
This paper focuses on the role of natural resources information in Oregon legislative
policy-making, based on the two legislative case studies from the 1991 Legislative Session,
surveys conducted of state natural resource agency legislative liaisons, and a review of
current literature addressing policy-making and the role of science in policy-making....
Oregon's estuaries have been significantly altered by human activity, so that many former tidal wetlands no longer provide the functions, such as fish and wildlife habitat, erosion protection from storms, and water quality maintenance, that preserve the integrity of estuarine ecosystems. Oregon has been a leader in wetland protection and...
"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...
Red Light Ladies presents a perspective on prostitution in North America, within the context of the western mining frontier. A biographical profile of the frontier
prostitutor is presented, along with an archaeological model of settlement patterns and material culture. Settlement patterns and demographic changes in the prostitutor
population are hypothetically...
Past disasters such as mercury poisoning in Minimata, and new problems such as tributyltin impacts on shellfish have maintained public concern about problems caused by chronic discharges of hazardous materials into marine waters (Clark, 1986; U.S. Congress, 1987). However, hazardous chemical spills in coastal waters typically escape public attention. Unlike...
Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...
