Bibliography of Douglas-fir provenance studies, 1907-1974

Creator:: Hermann, Richard K., Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is one of the world's most important and valuable timber trees. Its natural distribution in North America resembles an inverted V with uneven sides. From the apex in British Columbia, the western half extends along the Pacific mountain ranges into California for about 2,200 km...

Effect of seedbeds on germination and survival of Douglas-fir

Creator:: Hermann, Richard K., Chilcote, William W., and Oregon State University. Forest Research Laboratory
Abstract:: Germination and survival of Douglas-fir on seedbeds of unburned, lightly burned, and severely burned soil, charcoal, litter, and sawdust, exposed to 100, 75, and 25 percent of full light, were studied on a south-facing clearcutting in the Coast range of Oregon. Irrespective of exposure to light, germination was best on...

Mycorrhizae and survival of Douglas-fir seedlings

Creator:: Wright, Ernest and Oregon State University. Forest Research Laboratory
Abstract:: Correlation was sought between abundance of mycorrhizae on Douglas-fir seedlings and their survival in field plantations. One possible indication of dormancy desirable for lifting from nursery beds could be the varying seasonal abundance of ectotrophic mycorrhizae on roots of seedlings. No direct correlation between percentage of mycorrhizae and survival in...

Trees : timber resource economic estimation system

Creator:: Tedder, Philip L., Schmidt, James S., Gourley, Jonna, and Oregon State University. Forest Research Laboratory
Abstract:: Volume I: TREES (Timber Resource Economic Estimation System), a forest management and harvest scheduling model, is comprehensively described in the first of a four-volume series. Even- or uneven-aged forest inventories form basic resource units (BRUs), entered by age class or size and diameter classes; stocking level; and management intensity. Management...

Production rates and costs for cable, balloon, and helicopter yarding systems in old-growth Douglas-fir

Creator:: Dykstra, Dennis P. and Oregon State University. Forest Research Laboratory
Abstract:: This report describes initial results of a yarding time study for the Pansy Basin Study, a cooperative research project designed to test the performance of skylines, balloons, and helicopters operating under various conditions of timber and terrain, and over a range of silvicultural and landscape design prescriptions. Observations during the...

A technique for the solution of the catenary problem in surveying

Creator:: Wilson, Robert L., Dykstra, Dennis P., Sessions, John, and Oregon State University. Forest Research Laboratory
Abstract:: A technique for solving efficiently the catenary problem encountered in surveying with tapes is presented. The theory of the catenary solution is outlined, and our technique is shown to solve correctly the catenary for all conditions. Analysis of error that compared the catenary correction to the more commonly used parabolic...

Properties and uses of bark as an energy source

Creator:: Corder, Stanley E. and Oregon State University. Forest Research Laboratory
Abstract:: Energy is extremely important to all societies-but especially important to industrial societies. A characteristic of an industrial society is its enormous consumption of energy. Only in the past few years has there been a broad general concern about energy cost and supply. When petroleum prices increased by a factor of...

Snow damage to young Western hemlock and Douglas-fir

Creator:: Kangur, Rudolf and Oregon State University. Forest Research Laboratory
Abstract:: Data collected from permanent sample plots at medium and high elevations in Oregon's coastal forest clearly indicate that snow damage adversely influences stand development. Sapling stands of western hemlock and Douglas-fir were subjected to severe snow damage above 1,000 feet in the early parts of 1965 and 1966 and above...
