This study was started in 1947 to investigate the value of various types and quantities of seed source in the establishment of reproduction on cutover land, and to determine the apparent effects of various man-made and natural factors upon the rate of restocking. The man-made and natural factors to be...

Several generations of Oregonians carry memories of a series of forest fires so sweeping that they spurred an entire state into action. These fires created what was for a long time called the "Tillamook Burn" -- a wide swath of devastation cut through old growth forests in the Coast Range....

While the d⁰ transition-metal POMs of Group V (V⁵⁺, Nb⁵⁺, Ta⁵⁺) and Group VI (Mo⁶⁺, W⁶⁺) have been known for more than a century, the actinyl peroxide POMs, specifically those built of uranyl triperoxide or uranyl dihydroxidediperoxide polyhedra, were only realized within the last decade. While virtually every metal on...
This study was initiated and designed, first, to determine the reliability of the stocking survey system, and, second, to construct free hand curves which would give the ratio of percent of stocking to number of trees per acre.

Where a legacy of aggressive wildland fire suppression has left forests in need of fuel reduction, allowing wildland fire to burn may provide fuel treatment benefits, thereby reducing suppression costs from subsequent fires. The least-cost-plus-net-value-change model of wildland fire economics includes benefits of wildfire in a framework for evaluating suppression...
Oxidized intervals of five organic‐rich Madeira Abyssal Plain (MAP) turbidites deposited during the Miocene, Pliocene, and Pleistocene all displayed comparable major loss of total organic carbon (TOC) (84 ± 3.1%) accompanied by a negative isotopic (δ¹³C) shift ranging from −0.3 to −2.9‰. Major but significantly lower loss of total nitrogen...

Despite the efforts of natural resource economists to implement rights-based fishery management systems, many of the world’s fisheries remain over-exploited and lack an institution to change course. Given the status quo of overharvesting and depleted fish stocks, it seems natural for a harvester co-op to jointly curtail fishing mortality, which...
This study quantifies the short-term effects of low-, moderate-, and high-severity fire on carbon pools and fluxes in the Eastern Cascades of Oregon. We surveyed 64 forest stands across four fires that burned 41,000 ha (35%) of the Metolius Watershed in 2002 and 2003, stratifying the landscape by burn severity...
Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in pon-derosa pine (Pinus ponderosa) forests of central Oregon. The combustion of fuels containing large downedwood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previousstudies show ectomycorrhizal fungi (EMF) improve...

"On August 4, 1958, the Oregon Fish Commission entered into a two-year agreement with two California fishermen to do exploratory work off the Oregon coast for red abalone (Haliotis rufescens). In August 1960 the Fish Commission renewed this contract for two years with one of these fishermen. The purpose of...
This is a 1966 proposal to transplant about 500 red abalone (Haliotis rufescens) into Whale Cove on the Oregon Coast, and see if the abalone prospered. This proposal was approved, and the Oregon Dept. of Fish and Wildlife did launch this experiment.
