One of the most vexing problems facing the United States Forest
Service in Western Oregon concerns its management of undeveloped
forested lands. Many of these areas contain highly productive timberland,
and restriction of timber harvesting to preserve the land's
primitive character can be very costly. Also there are conflicting
pressures...
Knowledge of old-growth Juniperus occidentalis woodlands, which occur in central and eastern Oregon, is limited. Wise management of these woodlands necessitates a better understanding of the community ecology. The community structure of woodlands at seven sites in three areas of central Oregon was studied. Measurements taken at nine plots per...
This dissertation describes the epiphyte communities on tall shrubs in forests of
western Oregon, with a focus on potential effects of management practices on these
communities. Shrubs and other hardwoods have recently gained recognition as
hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...
Sixty nonindustrial small-forest owners were interviewed in
Lane County, Oregon to determine their objectives for forest lands,
and knowledge of and attitudes toward public assistance in forestry.
Owners were randomly sampled from a preselected size class
of 10 to 200 acres. A formal questionnaire was used to measure
forest land...
The forests of the Oregon Coast Range have been both the principal
natural resource, and for many years, the primary economic base of the region. In the past thirty years, changing social and economic factors have created new visions for these forests, leading to conflict over the appropriate management of...
Growth was assessed for Douglasfir reproduction which had established naturally beneath three intensities of overstory thinning in a 65-year-old stand of Douglas-fir on the east side of the Oregon Coast Range. The age of advanced reproduction ranged from 4 to 15 years. Understory environments were described in terms of sunlight,...
Our diagram is intended to provide general guidance in density management of red alder. The management zone defines a reasonable compromise between individual-tree and stand growth and mortality. Factors considered in its formation include desired tree size at harvest, growth rate, and yield per acre. Social and legal constraints, as...
The protection of sensitive resources is an integral part of forest practices regulations in many states, affecting non-industrial private forest (NIPF) landowners. In Oregon, forest operations on private lands which will conflict with sensitive areas designated "specified resource sites" must meet spatial and temporal requirements to protect those sites. These...
