Plant communities and succession in Oregon coastal salt marshes

Creator:: Jefferson, Carol A.
Abstract:: The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon. Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...

Stand Structures of Oregon White Oak Woodlands, Regeneration, and Their Relationships to the Environment in Southwestern Oregon

Creator:: Gilligan, Laurie A. and Muir, Patricia S.
Abstract:: Although Oregon white oak (Quercus garryana) woodlands are a characteristic landscape component in southwestern Oregon, little is known about their current or historical stand structures. Meanwhile, fuel reduction thinning treatments that change stand structures in non-coniferous communities are ongoing and widespread on public lands in this region; some of these...

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Vegetation Change from the Euro-American Settlement Era to the Present in Relation to Environment and Disturbance in Southwest Oregon

Creator:: Duren, Olivia C., Muir, Patricia S., and Hosten, Paul E.
Abstract:: Faced with landscapes degraded by fire suppression, logging, and grazing, land managers in the interior western US are attempting to restore habitat structure and function. In southwest Oregon, landscape-scale fuels treatments are being implemented with goals including recreating historic vegetation structure, despite poor understanding of the nature of the landscape...

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

The association of epiphytic macrolichens and bryophytes with riparian stand types along a valley continuum, Oregon Coast Range

Creator:: Ruchty, Andrea M.
Abstract:: I surveyed epiphytic macrolichens and bryophytes in six stands in each of seven riparian stand types in the Oregon Coast Range. This study (Chapter 2) describes the association of epiphytes with stand types and the corresponding potential of forest canopy conversions to affect epiphyte communities. Species composition, diversity, and representation...

Fungal and bacterial associations in heart rots of Abies concolor (Gord. and Glend.) Lindl. and techniques for estimating damage in southwestern Oregon

Creator:: Aho, Paul E.
Abstract:: Infection courts for microorganisms invading white fir heartwood were determined to be primarily branches and basal wounds. Of 11 hymenomycetes isolated from infected trees, only four: Echinodontiurn tinctorium, Phellinus chrysoloma, Pholiota adiposa, and Hericium abietis were of major significance in terms of frequency of infection and damage caused. Two or...

Distribution and prediction of Swiss needle cast of Douglas-fir in coastal Oregon

Creator:: Rosso, Pablo H.
Abstract:: This study was directed to improve our understanding of the ecology of Swiss needle cast (SNC) of Douglas-fir, a disease that produces extensive damage to forests and plantation in the coastal region of Oregon and Washington. A disease prediction model for the coastal area of Oregon was built by establishing...

Contributions to the plant ecology of the Oregon coastal sand dunes

Creator:: Wiedemann, Alfred M.
Abstract:: Sand dunes are found along the coasts of most of the large land masses of the world. Because of their proximity to man and his activities, the maritime sand dunes of Europe, particularly Germany, France, Holland and Scandinavia, have the longest history of stabilization activities and botanical investigation. There are...
