A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

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...

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,...

Regional gradient analysis and spatial pattern of woody plant communities in Oregon

Creator:: Ohmann, Janet L.
Abstract:: Knowledge of regional-scale patterns of plant community structure and controlling factors is largely qualitative and based on numerous local studies. Data from a subsample of 10,000 field plots were used to quantify and map compositional gradients of woody plant communities across Oregon forests. Canonical correspondence analyses explained 9-14% of the...

Application of Infrared Spectroscopy for Determination of Wood Natural Durability

Creator:: Lipeh, Shahlinney
Abstract:: Natural durability remains one of the most attractive characteristics of wood, and helps wood obtain a premium price. A worldwide shift towards the use of younger trees from intensively managed forests has created greater concerns about wood quality, especially the wood’s resistance to fungi and insects. Wood durability is assessed...

Silvicultural impacts of sheep grazing in Oregon's Coast Range

Creator:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...

The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

Creator:: Zybach, Bob
Abstract:: The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...
