  Citation × Citation Citation Abstract Copy Title: Early stages in plant succession on Douglas fir clearcuts on the Mary's Peak watershed near Corvallis, Oregon Author: Brown, Eugene Allen This study has been concerned with the patterns of vegetative changes which occur during the first five years following logging and burning on Douglas-fir clear cuts. Knowledge of the successional sequence in the coastal forests of western Oregon is of primary importance to those concerned with the management of this resource. From the more theoretical point of view, there are many unique features associated with this type of vegetation of special interest to the ecologist. Published accounts of studies in Oregon and Washington have been of a generalized nature. None have approached a localized area with the degree of intensity attempted in this study. Due to its close proximity to Oregon State University and the cutting and burning history of the area, the Mary's Peak Watershed has been especially suitable for this study. Mary's Peak is the highest point of the Oregon Coast range having an elevation of 4,097 feet. The Corvallis watershed is located on the eastern slope of the peak and includes both the Rock Creek and Griffith Creek drainages. The area is about five miles long east and west by four miles north and south. The area is managed as a unit by the United States Forest Service. Due to the marine influence, the area has a humid climate averaging approximately 65 inches of precipitation annually with an annual mean temperature of approximately 52°F. Soils are basaltic in origin and are primarily clay loam in texture. In 1950, an epidemic of Douglas fir bark beetles made necessary a program of development which included cutting of dead and infected trees and establishing a road system. Cutting was restricted to small clear cuts. The vegetation in the study area is a Douglas fir-vine maple association. Gaultheria shallon and Berberis nervosa dominate the forest floor with traces of Castanopsis, Corylus, and Cornus. Study plots were located on nine clear cut and burned areas ranging in elevation from 1,300 to 2,800 feet and including north, south, and east exposures. Nineteen study plots, which were 100 x 100 feet, were established in uniform vegetative areas. Plots were also established in the undisturbed areas adjacent to the clear cuts for comparative purposes. Vegetative sampling was done using a device called an ocular point frame which provided a reliable indication of vegetative cover. Sampling was done in both the spring and fall on the second, third, fourth, and fifth years following burning. The stable undisturbed vegetation was sampled only once. Results of the five-year study showed a general increase in total number of plant species. The average total vegetative cover rose abruptly the third, fourth, and fifth years. An analysis indicated that south exposed plots had the greatest vegetative cover the first five years after burning. East plots ranked second and north plots third. By the fourth year, average cover values on clear cut areas exceeded the cover values of understory vegetation on the adjacent uncut forest. Analysis of data regarding seasonal variation indicated sharp decreases in total cover from spring to fall during the first three years. Increasing amounts of perennial vegetation during the fourth and fifth years reduced this seasonal variation markedly. In terms of mean cover trends, the annual herb, Senecio sylvaticus, dominated the second year; Lotus stipularis and Circium vulgare, the third; Lotus and Holcus lanatus , the fourth and fifth. All plant species indicated a wide range of cover values on the plots sampled. Some consistent trends in the sequence of cover dominance are noted.

  Citation × Citation Citation Abstract Copy Title: Agricultural impacts on amphibian survival, growth, and distributions Author: Baker, Nick J. The potential impact of chemical contaminants and conservation practices on amphibians in agricultural landscapes is a key research topic globally. Amphibians represent a common group in many freshwater systems and are currently experiencing worldwide population declines. Global amphibian declines may be attributed to a number of causes, including habitat loss, introduced species, global climate change, disease, and chemical contaminants; most species declines are not a function of only one factor, but a result of interacting factors and synergistic impacts. I analyzed the impact of field conservation efforts employed in the Calapooia watershed, located in the central Willamette Valley in Oregon, on amphibian species diversity using Simpson's Diversity Index. In the Calapooia watershed the value of this index increased when conservation efforts, such as retaining crop residue and riparian buffers, were present. This suggests that species diversity increased with increased conservation effort at the field level. In addition, I found species-specific habitat associations in the Calapooia watershed. Long-toed salamanders (Ambystoma macrodactylum) were associated with stream channel cover. Rough-skinned newts (Taricha granulosa) and Red-legged frogs (Rana aurora) showed similar relationships to pH, bank width, depth, and riparian habitat where as Pacific treefrogs (Pseudacris regilla) showed strong relationships to increased structural heterogeneity, increased distance to nearest agricultural field, and increased human disturbance. These results indicate that conservation efforts can impact amphibian biodiversity, and that there are species-specific habitat associations in the Calapooia watershed. My third chapter looked at pesticides and fertilizers, which have been shown to negatively affect many species of amphibians. I used meta-analytic techniques to quantify the lethal and sub-lethal effects of pesticides and fertilizers on amphibians in an effort to review the published work to date. I found that, in general, pesticides and fertilizers negatively affect amphibians by reducing both survival and growth. Pesticide and fertilizer chemical classes showed differences in their impacts on amphibians: inorganic fertilizers, organophosphates, phosphonoglycines, and triazines negatively affected amphibian survival, while, organophosphates and triazines negatively affected amphibian growth.

  Citation × Citation Citation Abstract Copy Title: Clear and Foster Creek Watershed Assessment Abstract -- A watershed assessment was completed in the Clear and Foster Creek watersheds to evaluate existing conditions and make recommendations to protect or enhance watershed natural resources. Clear and Foster Creek are tributaries to the Clackamas River below any major dams on the system; consequently these tributaries are positioned favorably to contribute to recovery of important anadromous fish populations. Anadromous fish species in the Clackamas basin include spring and fall chinook, coho salmon, winter steelhead, summer steelhead (non-native), migratory cutthroat trout and lamprey. Clear and Foster Creeks are utilized by fall chinook, winter steelhead and coho salmon. The assessment generally followed the framework described in the Oregon Watershed Enhancement Board’s Watershed Assessment Manual (WPN, 1999). The assessment focused on the following components: Channel habitat classification and modification; hydrology and water use; riparian/wetlands; sediment sources; water quality; fisheries; and wildlife and upland vegetation. Generally the approach builds on existing information, and enhances this information with aerial photo interpretation and limited field checking. Additional fieldwork was used to verify channel habitat types and to characterize fish habitat condition. GIS was used as a critical assessment tool and method of displaying results.

  Citation × Citation Citation Abstract Copy Title: Climatic and physiographic controls on peakflow generation in the western Cascades, Oregon Author: Perkins, Reed Despite the importance of rain and snowmelt in causing peakflows in the Pacific Northwest, the interactive effects of a snowpack and watershed physiography on streamflow are largely undocumented. This study investigated the influence of soil and snowpack moisture on peakflow hydrograph shape in three small (< 60 ha) control sub-watersheds and the containing Lookout Creek Watershed (6200 ha) in the western Cascade Mountains of Oregon with three main objectives: 1) determine the statistical correlation between antecedent conditions and peakflow hydrograph shape within each small watershed; 2) determine how these correlations differed between small watersheds; and 3) determine the correlation between sub-watershed and Lookout Creek peakflow hydrograph shapes. A partial-duration set of peakflows was selected from at least 21 years of continuous discharge data for each small watershed using a linear quickflow vs. baseflow separation technique. Peakflows were then classified into three significantly different types based on estimated antecedent soil and snowpack moisture storage: "dry-soil rain" (e.g., soil moisture < 90 percent field capacity), "wet-soil rain" (e.g., soil moisture> 90 percent field capacity), and "wet-soil rain-on-snow". These three types accounted for over 70 percent of peakflows and over 80 percent of quickflow volume in each watershed. Generally, wet-soil rain peakflows began sooner after precipitation, lasted longer, and had larger instantaneous peaks than did dry-soil rain peakflows, while wet-soil rain-on-snow peakflows had the longest durations and largest instantaneous peaks. However, effects of soil wetting and snowpack on peakflow hydrographs differed significantly between watersheds. Lookout Creek peakflows occurred during several combinations of small watershed peakflow types, though the largest Lookout Creek peakflows were coincident with large, synchronized wet-soil rain-on-snow peakflows in Watersheds 2 and 8. Very little attenuation of the peakflow hydrograph was observed between the small watersheds and Lookout Creek. Results from this study indicate that by altering snowpack dynamics, and therefore the frequency distribution of peakflow types, climate change or land-use may differentially affect peakflow hydrographs in small watersheds. One consequence of this in Lookout Creek Watershed may be to desynchronize small watershed peakflow responses and decrease downstream peak size.
