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...
Resource Type:: Masters Thesis

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...

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)...

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...

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....
