Harvest scheduling and economic effects of old-growth forest preservation in northwest Oregon

Creator:: Hunt, Mary C.
Abstract:: Old-growth forests provide an important resource in terms of both timber and non-timber values. Northwest Oregon represents an area where this resource is scarce and options for preserving old-growth habitat are limited. This study identifies the old-growth resource on public lands within the area, suggests a range of preservation alternatives...

Age structure and spatial pattern of old-growth ponderosa pine in Pringle Falls Experimental Forest, central Oregon

Creator:: Morrow, Robert J.
Abstract:: The dynamics of stands In old-growth ponderosa pine (Pinus ponderosa) forests on the eastern flank of the central Oregon Cascades are Investigated. Age structure and spatial pattern of ponderosa pine within the Pringle Falls Experimental Forest Research Natural Area coupled with the fire history of the area aid In Interpreting...

Land cover at northern spotted owl nest and non-nest sites, east-central Coast Ranges, Oregon

Creator:: Perkins, John P.
Abstract:: This study examined the differences, at various scales, between northern spotted owl (Strix occidentalis caurina) nest sites and non-nest sites, i.e., sites where no nests were found during surveys, in the Coast Ranges of Oregon. I compared land cover around 41 owl nest sites (ONS) and 41 non-nest sites (NNS)...

Factors determining species composition of post-disturbance vegetation following logging and burning of an old growth Douglas-fir forest

Creator:: Clark, Deborah Louise, 1950-
Resource Type:: Masters Thesis
Full Text:: old growth Douglas-fir forest at 800 m elevation located in the western Cascades of Oregon

The fate of organic and inorganic nitrogen inputs in an old-growth forest of the central Oregon Cascade Range

Creator:: Holub, Scott M.
Abstract:: Forests in the Pacific Northwest receive very little nitrogen through atmospheric deposition and thus studying the nitrogen cycle in this region can provide insights into how the unpolluted nitrogen cycle functions. I examined the fate of organic nitrogen versus inorganic nitrogen and the effect of tamlins on N retention by...

Development, fire history and current and past growth, of old-growth and young-growth forest stands in the Cascade, Siskiyou and mid-coast mountains of southwestern Oregon

Creator:: Sensenig, Thomas S.
Abstract:: I evaluated fire occurrence, growth and recruitment and determined the fire history of 21 old and 20 young 8ha stands in Cascade, Siskiyou and mid-Coast mixed conifer and evergreen forests in southwestern Oregon. The rates and patterns of growth were measured and analyzed on 1,079 old-growth and 2,111 young stand...

Landscape patterns of pre-logging forest conditions in western Oregon

Creator:: Rasmussen, Mary C.
Abstract:: Using historical maps and tools provided by GJS, the spatial patterns of pre-logging forest conditions were quantified for three landscapes in western Oregon. The spatial coincidence between forest patches and topographic features was determined for slope gradient, aspect, elevation, and distance from streams. Pre-logging and current forest compositions were compared....

Ecology of forest floor bryophytes in Pseudotsuga menziesii-Tsuga heterophylla stands of western Oregon : implications for forest management

Creator:: Rambo, Thomas Roy
Abstract:: Species richness and abundance of forest floor bryophytes, including epiphytes from incorporated litterfall, were assessed at two sites in western Oregon. Bryophyte diversity, abundance, and community composition were compared between sites, and between young forest stands ([approximately] 55 yrs.) and old-growth stands (400+ yrs.) within each site. Relationships of stand...

Structure and development of old-growth Douglas-fir in central western Oregon

Creator:: Poage, Nathan Jeremy
Abstract:: The tree species and size structure of 9l old-growth forests dominated by Douglas-fir in central western Oregon was characterized using complete inventories of all trees larger than 20cm dbh over a mean area of 17.1ha at each site. Douglas-fir accounted for over 75% of the total average basal area (39.1...
