In this paper the extent of the steep slope brush conversion problem will be estimated. Potential solutions and development should be commensurable with the extent of the problem. The state-of-the-art of steep slope site preparation and conversion will
be described. Feasible alternatives to these limited options will be developed.
This paper describes a mathematical formulation and computer
programs for use on hand-held programmable calculators to analyze
the load carrying capacity of skyline systems, including the effects
of log drag. The actual physical characteristics of the load and
the ground geometry are used in the analysis of the payload capacities...
During the 1981 grazing season four sets offecal
coliform (FC) concentration data were collected from
streams on sheep grazed clear cut units on the Alsea
Ranger District of the Siuslaw National Forest. The objective
of the study was to access bacterial water quality impacts
from sheep grazing. Sample sites were...
Human activity has led to the reactivation of
portions of a Pleistocene landslide complex in The Dalles,
Oregon. Slope movements are in rocks of the Chenowith
formation: agglomerate, conglomerate, tuff breccia, sandstone,
and siltstone. Slope movements occur in at least
two distinct areas in The Dalles. At one, the shear...
Retaining agricultural land was a significant concern of Oregon
legislatures throughout the l960s and 1970s. Willamette Valley counties
primarily use a minimum lot area standard to retain land for agricultural use.
Lot area standards used in portions of Yamhill and Clackamas Counties play a
conservative force in each county's land...
Knowledge of the timber production potential of a wildland area plays an important role in its wise management. For the past several years, resource managers of the United States Forest Service (USFS) at the Plumas National Forest have been concerned with the establishment of a procedure to evaluate timber production...
