-
(NRC Canada, 2002)We examined the effects of species, initial substrate quality, and site differences (including temperature, precipitation, and soil N availability) on fine-root (<2 mm diameter) decomposition in litter bags and its N dy ...
-
(Elsevier, 2012-01)Euro-American settlement and organized fire suppression have been associated with structural and compositional changes in many upland forests of the western United States, but little is known about the impacts on riparia ...
-
(Society of American Foresters, 2007)Forest measurement and biometrics (FMB) programs have been at the heart of forestry education in North America since its beginnings at the Biltmore Forest School more than 100 years ago. Over the intervening period, the ...
-
(Pacific Southwest Research Station, 2007-08)This study is the first in a series of studies to evaluate perceptions of USDA Forest Service law enforcement personnel of the roles, responsibilities, and issues entailed in their jobs. An email survey was administere ...
-
(Pacific Southwest Research Station, 2008-05)This is the fifth in a series of studies to evaluate perceptions of the roles, responsibilities, and issues entailed in the jobs of U.S. Department of Agriculture Forest Service law enforcement and investigations (LEI) ...

(Pacific Southwest Research Station, 2007-09)This is the third in a series of studies to evaluate perceptions of USDA Forest Service law enforcement personnel of the roles, responsibilities, and issues entailed in their jobs. An e-mail survey was administered to ...

(Pacific Southwest Research Station, 2007-10)This is the fourth in a series of studies to evaluate perceptions of U.S. Department of Agriculture Forest Service law enforcement personnel of the roles, responsibilities, and issues related to their jobs. An e-mail sur ...
-
(NRC Canada, 2001)This study was designed to measure the microbiological and chemical characteristics of forest soils in a chronosequence of harvested Douglas-fir (Pseusotsuga menziesii (Mirb.) Franco) stands in different climatic setting ...
-
(Springer, 2012-12)Douglas-fir (Pseudotsuga menziesii) forest residues were physically fractionated through sieving. The bark and wood were separated for large-sized fractions (>12.7 mm), and their contents were determined. The chemical co ...
-
(NRC Canada, 1999)Associations between the golden metallic beetle, Buprestis aurulenta L., and wood-destroying fungi were explored with adult beetles collected from log decks. A variety of fungi were isolated from the beetle bodies by fou ...
-
(Society of Wood Science and Technology, 1993-10)Differences in stain susceptibility were evaluated on sterile and unsterile samples of freshly sawn, frozen and thawed, or oven-dried and rewetted ponderosa pine sapwood. Samples treated with sterile medium or with mediu ...
-
(Society of Wood Science and Technology, 1988-04)Heartwood from coastal redwood [Sequoia sempervirens (D. Don.) Endl.] is very durable and is often used untreated in harsh environments, such as cooling towers of power or chemical processing plants. Wood in this environ ...
-
(Springer, 2011-09)A new approach was developed for the evaluation of energy release rate by the virtual crack closure technique in quadratic and linear elements. The generalized method allows arbitrary placement of the side nodes for quad ...
-
(Corvallis, OR: Forest Research Laboratory. Oregon State University, 1992)
-
(NRC Canada, 2000)Genetic control of cold hardiness in two-year-old seedlings was compared with that in 7-year-old saplings of 40 open-pollinated families in each of two breeding populations (Coast and Cascade) of coastal Douglas-fir (Pse ...
-
(Springer Verlag, 2006)Douglas-fir trees from 39 open-pollinated families at four test locations were assessed to estimate heritability of modulus of elasticity (MOE) and basic density. After trees were felled, sound velocity was measured ...
-
(NRC Canada, 1999)The extent to which parent trees within breeding zones of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) are locally adapted to their native environments was evaluated. Forty families from each ...
-
(NRC Canada, 2002-05-13)Abstract: Genetic variation in drought hardiness traits and their genetic correlations with growth potential and17re1c6overy traits were investigated in 39 full-sib families of coastal Douglas-fir (Pseudotsuga menziesii ...
-
(NRC Canada, 2000-01-25)Abstract: Variation in cold-hardiness traits, and their extent of genetic control and interrelationships, were investigated among individuals (clones) within a single large full-sib family of coastal Douglas-fir (Pseudo ...
