Quantifying Aboveground Biomass for Common Shrubs in Northeastern California

Creator:: Huff, Steven
Abstract:: Quantifying biomass is important for sustainable forest management. The purpose of this study is to obtain allometric relationships for seven species of shrubs common in northeastern California so that estimates of carbon and fuel loading may be better realized. Although some shrub biomass equations exist, such equations are limited in...

Historical fire regime in the Little River watershed, southwestern Oregon

Creator:: Van Norman, Kelli J.
Abstract:: Disturbances are a prevalent and important part of ecosystems. Many landscape patterns that we find today were created, maintained, and changed by natural disturbance regimes. This is especially true for fire, which has historically been a common, natural disturbance in the western U.S forests and grasslands and many other parts...

Nitrogen dynamics across silvicultural canopy gaps in young forests of western Oregon

Creator:: Thiel, Aaron L.
Abstract:: Silvicultural canopy gaps are emerging as an alternative management tool to accelerate development of complex forest structure in young, even-aged forests of the Pacific Northwest. I investigated patterns of nitrogen (N) availability along transects through 0.1 and 0.4 ha silvicultural gaps in three 50-70 year old Douglas-fir forests of western...

Regional variation of pull factors for retail sales in Oregon's nonmetropolitan counties 1979, 1982, 1984

Creator:: Corcoran, Patrick
Abstract:: The performance of pull factors for total retail sales in Oregon's nonmetropolitan counties during the economic cycle of boom, bust, and recovery of the early 1980s is examined for geographic patterns. One regional pattern and several county patterns are identified and discussed. Counties having the highest and lowest pull factors,...

Nuclear and mitochondrial DNA polymorphism and phylogeny in the California closed-cone pines

Creator:: Wu, Junyuan
Abstract:: We studied genetic polymorphism and phylogeny using nuclear random amplified polymorphic DNA markers (RAPDs) and mitochondrial DNA (mtDNA) restriction fragment length polymorphisms (RFLPs) in the three California Closed-Cone Pines: Pinus attenuata Lemm., P. muricata D. Don, and P. radiata D. Don. A total of 343 to 384 trees derived from...

Tree species-soils relationships in old-growth forests of the Oregon Coast Range

Creator:: Cross, Alison
Abstract:: Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and bigleaf maple) in mixed-species old-growth forests of the Oregon Coast Range and to determine whether and how soils differ among the...

Wildland fire in ecosystems : effects of fire on fauna

Creator:: Lyon, L. Jack, Huff, Mark H., Hooper, Robert G., Telfer, Edmund S., Schreiner, David Scott, and Smith, Jane Kapler
Abstract:: Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire...

Phylogeography, evolution, and conservation in forest-associated Pacific Northwest salamanders

Creator:: Wagner, R. Steven
Abstract:: Phylogeographic studies of six Pacific Northwest forest-associated salamanders provide insight into historical and contemporary processes on population genetic structure. Among Larch Mountain Salamanders (Plethodon larselli), cytochrome b mitochondrial (mtDNA) sequences (381 bp) and random amplified polymorphic DNA (RAPDs; 34 loci) supported separate Management Units for northern and southern populations (12...

Public domain withdrawn from mineral entry in Wallowa-Whitman National Forest: a case study

Creator:: Andersen, Steven B.
Abstract:: Since the passage of the mining and mineral leasing laws, a considerable amount of the public domain has been excluded from mineral exploration and development. It has been estimated that as much as fifty-three and sixty-four percent of the public lands have been withdrawn from the jurisdiction of the mining...
