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...

Abstract:: The response of western hemlock (Tsuga heterophylla [Raf.] Sarg.) to two methods of site preparation for planting was compared. One site was cleared of mature brush by the "brown-crush-and-burn" method. The other was partially cleared by spraying with herbicides. Seedlings lifted and planted in December, January, February, and April were...

Abstract:: Naturally durable woods have a variety of commercial uses. Natural resistance to decay has been evaluated in field and laboratory tests of wood from many species, but there are few places where commercial wood users can find comparative assessments of natural durability. In this report, previous studies have been used...

Abstract:: Production rates, skidding costs, and soil disturbance were compared for two partial-cut units-one with preplanned skid trails and winching and one conventional unit-harvested with a Caterpillar D-7F. For the unit with preplanned skid trails and winching, production was 11 percent less, and skidding cost per unit volume was 29 percent...

Abstract:: "An important limitation In the study of tree roots has traditionally been the time necessary to excavate roots without injuring their fine structure. Thus, many root studies have been based on small samples and consequently contain large errors of estimation. This Note describes how large numbers of root systems from...
