Characteristics and spatial relationships of day-roosts and activity areas of female long-eared myotis (Myotis evotis) in western Oregon

Creator:: Waldien, David L.
Abstract:: Management of habitat for bats requires sound information on their habitat requirements. I used radio telemetry to identify 80 roosts for 24 long-eared myotis (Myotis evotis); 74 roosts were identified for 21 females and 6 roosts for 3 males. Females primarily used dead and defective conifer trees (n=22) and conifer...

Genetics of stem volume, stem form, and branch characteristics in sapling Noble fir

Creator:: Doede, David L.
Abstract:: Noble fir (Abies procera Rehd.), an important conifer in the Pacific Northwest, is valuable for timber, Christmas trees, and greenery products. A number of tree improvement programs emphasizing genetic improvement of bole volume growth are underway in this species. The purpose of this study was to estimate genetic control of...

Physical dimensions and hydrologic effects of beaver ponds on Kuiu Island in southeast Alaska

Creator:: Beedle, David L.
Abstract:: Dimensional characteristics of 44 beaver dams and ponds on Kuiu Island in Southeast Alaska were determined to evaluate the hydrologic effects of these structures on peak flows. The study area consisted of low gradient, incised streams in broad U-shaped valleys. Pond routing simulations were conducted using four return intervals (2-,...

Predicting height for undamaged and damaged trees in southwest Oregon

Creator:: Hanus, Mark L., Hann, David W., and Marshall, David D.
Abstract:: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for various tree species common to southwest Oregon. Data for damaged and undamaged trees were analyzed with weighted nonlinear regression techniques. The effects of specific damaging agents and their severity on the height-diameter...

Height-diameter equations for six species in the coastal regions of the Pacific Northwest

Creator:: Hanus, Mark L., Marshall, David D., and Hann, David W.
Abstract:: Three equations for predicting tree height as a function of diameter (outside bark) at breast height are presented for six species found in coastal regions of the Pacific Northwest. Foresters can use these “height–diameter” equations to avoid the time-consuming task of measuring heights of all individual trees in an inventory,...

Mechanical stress grading of dahurian larch structural lumber

Creator:: Gupta, Rakesh, Ethington, Robert L., and Green, David W.
Abstract:: The objective of this study was to test a method under development for assigning allowable properties to foreign species graded by American Lumber Standard machine-stress-rated (MSR) rules. The method was tested on dahurian larch (Larix dahurica), a major softwood species that grows in the Russian Far East and could be...

Forest insect ecology and management in Oregon

Creator:: Filip, Gregory M., Overhulser, David L., and Oester, Paul T.
Abstract:: This manual is intended for forest land owners and managers who want to understand and prevent unnecessary forest damage from insects. This manual covers only insects that infest living trees, not those that infest dead wood. The manual is organized into chapters based on the part of the tree that...

Carbon limitation of ammonium uptake by heterotrophic bacteria in the subarctic Pacific

Creator:: Kirchman, David L., Keil, Richard G., and Wheeler, Patricia A.
Abstract:: The purpose of this study was to test the hypothesis that NH4+ uptake by heterotrophic bacteria in the subarctic Pacific is C limited. Addition of glucose (0.5–1.0 μM) stimulated NH4+ uptake in unfractionated water but had no effect on bacterial abundance. Glucose stimulation of NH4+ uptake was even greater in...

Labor demand, productivity and overhead cost estimates for harvesting the 1990 strawberry crop

Creator:: Mason, Robert George, Cross, Timothy L., and Thomas, David Lee, 1949-
Abstract:: This is the third study of farm labor the Agricultural Experiment Station has completed for the Oregon Strawberry Commission. The first was completed for the 1987 harvest season. The second was completed for the 1989 season. This report covers the 1990 harvest year. The strategy for this study has been...
