Research and Scholarly Activities
1980 - June 1993: 0.0 FTE; June 1993 - Present: 0.5 FTE
Until June 1993 Dr. Emmingham had no formal research assignment and conducted research in
concert with his Extension duties. Starting in June 1993, he was assigned half time to the
Adaptive Research Group of the Coastal Oregon Productivity Enhancement (COPE) Program.
Research Accomplishments - 1980 to present
Highlights and Impact
- Ecosystem Management: Dr. Emmingham is a leader in development of alternative
silviculture for Northwest Forests with newly installed experiments in (1) management
of young plantations within spotted owl reserves in cooperation with the Siuslaw NF,
and (2) management of Ponderosa pine/mixed conifer forests in cooperation with the
- Impacts: In addition to numerous publications cited below, these research and
demonstration areas have been used for a variety of continuing education and
Extension programs. This has contributed directly to changes in land management,
ranging from improved knowledge of resource management to increased income and
better land stewardship.
Dr. Emmingham has installed and maintained a series of applied silviculture
demonstration/studies, published a variety of research, and extension publications and
shared results at numerous scientific meetings.
The applied silviculture demonstration studies (set up jointly with forestry Extension
agents) were aimed at filling the practical information needs of a range of professional
resource managers and especially the small private owner. These areas include studies
- Thinning of young red alder stands and underplanting western hemlock.
- Comparing selection and low thinning in commercial Douglas-fir stands.
- Thinning of ponderosa pine and mixed conifer stands in eastern Oregon.
- Planting and spacing trial of black cottonwood.
- Vegetation management for eastern Oregon forest types.
These study sites were used as field teaching sites to show small woodland owners
practical ways to manage their own forests, however, they also serve as research sites
because they were carefully designed and replicated. The alder study, for example,
was used for four regional workshops over a ten year period and was the basis for 3
More recently, through involvement in the COPE Program, Dr. Emmingham
provides leadership in additional applied silviculture research including:
- Establishment, culture and behavior of forest filter belts along agricultural
- Commercial thinning to enhance structural diversity in young Douglas-fir
- Response of conifers planted or released in hardwood dominated riparian zones.
