Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

Swinging and processing whole tree, tree length, and log length pieces in a Douglas-fir thinning

Creator:: Burrows, James O.
Abstract:: This paper describes a study done on swinging and processing whole tree, tree length and log length pieces in a smallwood Douglas-fir thinning. Two machines were evaluated, a 70 horsepower rubber tired skidder and a hydraulic loader mounted on a 6 x 4 live tandem truck. The study took place...

The loading of second-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco): to simulate the forces acting on an intermediate support tree

Creator:: Sedlak, Jerome Peter
Abstract:: The comercial thinning of second-growth stands in the Pacific Northwest is becoming increasingly important for satisfying the demand for timber. Cable logging will require the rigging of smaller intermediate support trees rather than those utilized on old-growth timber sales. This paper reports on the results of a study designed to...
