Potential for Coastal Wetland Blue Carbon Offset Projects in the Point Reyes Area

Creator:: Minnick, Margaret T.
Abstract:: Point Reyes is a 100-square mile peninsula located on the California coast about 30 miles north of San Francisco. The peninsula, surrounding bays, and neighboring coastal mainland are a unique biodiversity hotspot. The area underwent heavy human use, including ranching and logging, during the late 1800s and early 1900s. Conservation...

Interspecific carbon transfer in ectomycorrhizal tree species mixtures

Creator:: Simard, S. (Suzanne)
Abstract:: The overall goal of this study was to investigate influences of ectomycorrhizae (EM) and interspecific carbon transfer on seedling performance in species mixtures. The objectives were to: (I) determine the potential for EM to link paper birch and Douglas-fir, (ii) quantify gross and net interspecific carbon transfer, and (iii) evaluate...

Study of some biological and nutritional factors that influence nodulation by Frankia on red alder (Alnus rubra) and snowbrush (Ceanothus velutinus) within three age-class Douglas-fir forests in H.J. Andrews Experimental Forest, Oregon

Creator:: Rojas-Melo, Nestor S.
Abstract:: Bioassays using red alder and snowbrush plants grown in soils collected from a clearcut, a young Douglas-fir plantation, and an old-growth stand were conducted. Sites are located at the Andrews Experimental Forest, Oregon. In the first bioassays, more alder than snowbrush plants survived and nodulated. Of the plants that survived,...

A sustainable resource development plan framework for the Neskonlith Indian Band, British Columbia

Creator:: Mackasey, J. Patrick
Abstract:: A sustainable resource development plan framework was prepared for the Neskonlith Indian Band, who are located in the interior of British Columbia, Canada. The framework intends to address issues involving; integrated resource management, traditional native land management, ecosystem management, and community-based resource management. A soft systems (Wilson & Morren, 1990)...

Studies on Acacia senegal (L.) Wild. in western Sudan with special reference to variation among populations, host x soil inoculum interaction among populations, and host x Rhizobium strains interactions

Creator:: Elhadi, Faroug Mohamed
Abstract:: Seeds of A. senegal (L.) Wild from four populations across a rainfall gradient in western Sudan were grown in two sites. One site is on an upper dune crest - (sandy soil) and the other site is on the lower slope of the same dune - (sandy loam soil). Soils...

Mycorrhiza formation and diversity in undisturbed forest and clearcut and burned areas in three forest types in Oregon

Creator:: Brainerd, Richard E.
Abstract:: A greenhouse bioassay was used to compare ectomycorrhiza formation and diversity in soils from undisturbed and clearcut and burned areas in moist mesic, moist montane and dry montane forest types representing a gradient of environmental harshness. It was hypothesized that mycorrhiza diversity decreases with increasing environmental harshness and that stability...

Growth and mycorrhiza formation of Douglas-fir seedlings grown in soils collected at different distances from hardwoods pioneering southwest-Oregon clearcuts

Creator:: Borchers, Susan L.
Abstract:: A greenhouse bioassay was used to compare the effects of soils collected at different distances from hardwood species on the growth, mycorrhiza formation, and foliar nutrient concentrations of Douglas-fir seedlings. Soil nutrient concentrations and bulk densities were also determined. Soils were collected from two southwestern Oregon sites that had been...

The influence of stand structure and topography on growth, leaf area and efficiency of young Douglas-fir in the Oregon Coast Range

Creator:: Kaiser, Elisabeth H.
Abstract:: The relative influences of stand structure and topographic variation on volume growth, photosynthetic surface area, and stem growth efficiency were determined for six 17 to 23 year old well stocked stands in the central Oregon Coast Range. Plots were assigned to topographic classes (aspect, slope steepness, and slope position), by...

Vegetation-environmental relationships on two clearcuts on the western slopes of the Oregon Cascades

Creator:: Egeland, Dawn M.
Abstract:: Douglas-fir and western hemlock growth and stocking were examined on two neighboring clear-cut watersheds in the Western Cascades of Oregon and related to the intensity of burning and logging disturbance, habitat type, soil type, aspect and the influence of percent cover of both invading Ceanothus species and residual Acer circinatum....
Resource Type:: Masters Thesis

The ecological legacy of Indian burning practices in southwestern Oregon

Creator:: Carloni, Kenneth R.
Abstract:: Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....
