Cesium radioisotope content of wild edible fungi, mineral soil, and surface litter in western North America after the Fukushima nuclear accident

Creator:: Trappe, Matthew J., Minc, Leah D., Kittredge, Kimberly S., and Pink, Jeremias W.
Abstract:: We measured activity levels of cesium radioisotopes ¹³⁴Cs and ¹³⁷Cs in wild edible fungi, mineral soil, and surface litter of the west coast of North America from southern California to northern Vancouver Island after the Fukushima nuclear accident. All activity measurements were below governmental limits for human health. ¹³⁷Cs activity...

Potential financial returns from alternative silvicultural prescriptions in second-growth stands of coastal British Columbia

Creator:: Howard, Andrew F. and Temesgen, H.
Abstract:: This paper reports the findings from a study made of the potential financial returns from nine alternative silvicultural prescriptions applied to four case-study stands of second growth in coastal British Columbia. The objectives were to compare prescriptions based on partial cutting with conventional clear-cutting and to explore the effects of...

Effect of growth rate on the anatomy, specific gravity, and bending properties of wood from 7-year-old red alder (Alnus rubra)

Creator:: Lei, Hua, Gartner, Barbara L., and Milota, Michael R.
Abstract:: Understanding the association between growth rate and wood properties is of practical importance to maximizing and sustaining wood and fiber production. Anatomical characteristics, specific gravity, and bending properties were determined at breast height for thirty 7-year-old trees with varying growth rates, from a red alder (Alnus rubra Bong.) plantation. Wood...

Stem form and compression wood formation in young Pinus radiata trees

Creator:: Lachenbruch, Barbara, Droppelmann, Fernando, Balocchi, Claudio, Peredo, Miguel, and Perez, Erika
Abstract:: The crooked stems of some individuals of radiata pine (Pinus radiata D. Don) can hinder volume recovery and wood quality. To infer causes of crookedness and to learn how angle affects compression wood (CW) formation we studied 4+1-year old trees in southern Chile. Eight initially straight and 8 initially crooked...

Short-term effects of fire and forest thinning on truffle abundance and consumption by Neotamias speciosus in the Sierra Nevada

Creator:: Meyer, Marc D., North, Malcolm P., and Kelt, Douglas A.
Abstract:: In many western North American forests, prescribed burning and mechanical thinning are widely used to reduce fuels and restore stand conditions after a century of fire suppression. Few studies have followed the relative impacts of these treatments on the production and consumption of truffles in forest ecosystems, particularly in the...

Diversity and productivity of hypogeous fungal sporocarps in a variably thinned Douglas-fir forest

Creator:: Colgan, Wesley, Carey, Andrew B., Trappe, James M., Molina, Randy, and Thysell, David
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...

Density, ages, and growth rates in old-growth and young-growth forests in coastal Oregon

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...

Effects of height imputation strategies on stand volume estimation

Creator:: Garber, Sean M., Temesgen, Hailemariam, Monleon, Vicente J., and Harm, David W.
Abstract:: Subsampling and subsequent imputation of tree heights can improve the predictive performance of stand volume estimation but may also introduce biases. Using coastal Douglas-fir data from southwest Oregon, USA, the predictive performance of several height imputation strategies for estimating stand volume was evaluated. A subsample of 1-15 trees was randomly...

Influence of species proportion and timing of establishment on stem quality in mixed red alder – Douglas-fir plantations

Creator:: Grotta, Amy T., Gartner, Barbara L., and Radosevich, Steven R.
Abstract:: The relationships among stand structure, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) branch characteristics, and red alder (Alnus rubra (Bong.)) stem form attributes were explored for 10- to 15-year-old trees growing in mixed Douglas-fir – red alder plantations. Treatments included a range of species proportions, and red alder was either planted simultaneously...
