Abstract:: The effects of prescribed underburning on soil total C pools, total and inorganic N pools, and in situ net N mineralization were examined during a 1-year study in ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.) sites that had been experimentally burned 4 months, 5 years, or 12...

Abstract:: This publication is part of a 1-year project funded by the Oregon Department of Agriculture, Alternatives to Field Burning Program. Crop substitution is one strategy for reducing smoke from field burning. The objective of the project was to evaluate the potential for hybrid poplar as an alternative crop for poorly...

Abstract:: Concentrations of 14 chemical elements (Al, B, C, Ca, Cu, Fe, K, N, Mg, Mn, Na, P, S, Zn) were measured in wood and bark of 126 sample trees representing different stages of decomposition in three major tree species of northwestern Russia: Scots pine (Pinus sylvestris L.), Norway spruce (Picea...

Creator:: Acker, Steven A., Zenner, E. K., and Emmingham, W. H.
Abstract:: Green tree retention, a practice based on ecosystem science, has been integrated into forest management as a working hypothesis, requiring research and monitoring to quantify its effects. We undertook a retrospective study of natural, two-aged forest stands on the Willamette National Forest to provide preliminary estimates of the effects of...

Creator:: Tappeiner, John C., Huffman, David W. (William), 1962-, Marshall, David, Spies, Thomas A., and Bailey, John D.
Abstract:: We studied the ages and diameter growth rates of trees in former Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) old-growth stands on 10 sites and compared them with young-growth stands (50-70 years old, regenerated after timber harvest) in the Coast Range of western Oregon. The diameters and diameter growth rates for the...

Abstract:: Summaries from 49 published articles on site-index and dominant-height growth curves and equations are presented for 20 tree species or species groups found in California, Oregon, Washington, British Columbia, southeastern Alaska, Idaho, and western Montana. The summaries are organized by species. Each summary describes the modeling approach, type of curves/equations,...

Abstract:: Although ecosystem management techniques are designed to enhance species diversity in managed forests, no comprehensive study has been conducted to evaluate effects of such techniques on diversity and productivity of hypogeous fungi (truffles). During this study, truffles were collected in a 55- to 65-year-old Douglas-fir forest from March 1993 through...

Abstract:: Clearcut and shelterwood reproduction methods are both important, silviculturally viable reforestation tools for southwest Oregon. The ecology of local forests lends itself to the successful application of either method, in most cases; thus, choice of method is typically based on land management objectives, which integrate social and resource values, economics,...
