Plant and amphibian assemblages in zero-order basins in the Oregon Coast Range

Creator:: Sheridan, Chris D.
Abstract:: We have a poor understanding of the biotic communities in zero-order basins, drainages extending from ridgelines to the initiation of first-order streams. This study describes baseline plant and amphibian composition in unmanaged zero-order basins in the Oregon Coast Range. Specifically, I studied: i) the spatial distribution and diversity of species,...

The structure and dynamics of red alder communities in the central coast range of western Oregon

Creator:: Carlton, Gary C.
Abstract:: Red alder (Alnus rubra Bong.) is a fast-growing pioneer species that colonizes disturbed forest sites west of the Cascade Mountains in the Pacific Northwest. Streambottoms, toe slopes, and mass movement of surface soils have historically provided the scarification and soil moisture necessary for successful regeneration of red alder. During the...

Non-forest Plant Communities of the Northern Oregon Coast Range and Vicinity Draft Report

Creator:: Glavich, Doug
Abstract:: DRAFT REPORT. In 2013 – 2015, reconnaissance observations were made across non-forest habitats on FS and BLM land in the Coast Range and Cascade foothills within the Salem and Eugene BLM district areas for plant communities that did not fit the USFS Northwest Oregon Non-forest Plant Community guide. Surveys were...

The effect of riparian buffer strips on salmonberry (Rubus spectabilis) community structure in alder stands of the Oregon Coast Range

Creator:: Froyd, Cynthia A.
Abstract:: Salmonberry community structure was examined in alder-dominated riparian buffer strips in the Oregon Coast Range. Salmonberry growing on slopes was found to respond differently, to both characteristics of the buffer strips and to environmental factors, than salmonberry growing on terraces. Salmonberry, as measured by total height, number of ramets or...

Growth and carbon allocation of red alder seedlings grown over a density gradient

Creator:: Giordano, Peter A.
Abstract:: The amount and quality of competition among individuals in developing plant communities is an important factor determining community structure, composition and development. In perennial plant communities, this competition is reflected by shifts in carbon allocation among plant parts and can result in long-term structural differences between neighboring individuals. This study...

Comparison of soil and vegetation map delineation shapes and areal correspondence

Creator:: Bilton, Janet
Abstract:: Map delineations of soil and vegetation for a 14,000 acre (5,800 hectare) site in the Oregon Coast Range were compared. Research objectives were to ascertain the types of information that could be extracted from delineation comparisons and to develop a methodology suited to this purpose. The latter objective was achieved...

Similarities in understory vegetation composition between unthinned, thinned and old-growth Douglas fir stands in western Oregon

Creator:: Mayrsohn, Cheryl
Abstract:: Forest stands were studied to determine if old-growth forest structure could be mimicked in younger stands via overstory manipulation. Cover and species composition of understory plants were systematically sampled in sixteen thinned second-growth stands and sixteen adjacent unthinned second-growth Douglas fir (Pseudotsuga menziesii (Mirabel) Franco.) stands. The stands were thinned...

Occurrence of ectomycorrhizae on ericaceous and coniferous seedlings grown in soils from the Oregon Coast Range

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Seedlings of Gaultheria shallon, Pseudotsuga menziesii, Rhododendron macrophyllum and Tsuga heterophylla were grown together in the greenhouse in soils from three young managed Douglas-fir forests in the Oregon Coast Range. The main objectives were 1 )to evaluate the ability of ericaceous plants and overstory conifers to share compatible mycorrhizal fungi...

Interspecific competition in young Douglas-fir plantations of the Oregon coast range

Creator:: Wagner, Robert Gordon
Abstract:: Improving vegetation management decisions in Pacific Northwest forests requires a better understanding of the interactions between planted conifers and associated vegetation. A practical index of interspecific competition, and quantitative models predicting conifer performance from such an index are particularly needed. To meet this need, neighborhood models of interspecific competition were...
