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...

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...

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...

Public domain withdrawn from mineral entry in Wallowa-Whitman National Forest: a case study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

The influence of climate change and restoration on stream temperature

Creator:: Diabat, Mousa
Abstract:: Water temperature is an essential property of a stream. Temperature regulates physical and biochemical processes in aquatic habitats. Various factors related to climatic conditions, landscape characteristics, and channel structure directly influence stream temperature. Numerous studies indicate that increased average air temperature during the past century has led to stream warming...

Neutronic Analysis of a Liquid Metal Fast Reactor Experiment in the Large-I Position of the Advanced Test Reactor

Creator:: Lilley, Benjamin C.
Abstract:: Material testing experiments are needed to enable the next generation of nuclear fission reactors. Concluding in 2009, the Boosted Fast Flux Loop (BFFL) project was devised as a way to test fast reactor materials and fuels in the Advanced Test Reactor (ATR), however the experiment location it used is now...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...
