Genetic and Silvicultural Foundations for Management
Experiments on three sites address important
questions about the long-term effects of management on site productivity,
nutrient budgets, and soil processes. These studies are part of the
Pacific Northwest component of The
North American Long Term Soil Productivity Experiment network. The
Conifer Regeneration in Second-Growth Douglas-fir Stands
In the Belowground
Competition Study on Fort Lewis (WA), we tested the influences of
root competition on the growth of Douglas-fir saplings.
The Overstory Density
Study on the Washington Department of Natural Resources (DNR) Capitol
Forest is investigating the effects of overstory density levels on tree
growth and microclimate.
Oregon White Oak
Oregon white oak (or Garry oak) is the only oak species
native to British Columbia, Washington, and northern Oregon. We are
studying many aspects of Oregon
white oak biology and management.
Silvicultural Options for Harvesting Young-Growth
This operational-scale Silvicultural
Options Study on the Washington DNR Capitol State Forest examines
six different harvest treatments. The issues leading to the development
of this study are discussed in an edition of the PNW Research Station's
Alternative Silvicultural Treatments for
Young Plantations in the Pacific Northwest
Young conifer plantations can be treated in ways that
will result in different stand structures, tree characteristics, and
vegetation development in the future. Five treatments are being evaluated
at two sites:
Managing for Late-Successional Attributes
Olympic Habitat Development Study is a cooperative study with the
Olympic National Forest and the Olympic Natural Resources Center.
The study tests alternative treatments in 30- to 70-year-old forests
to accelerate the development of stand structures and plant and animal
communities associated with late-successional (old-growth) forests.
Additional information on variable-density
management is available.

Forest Visualization Models and Remote Sensing
LIDAR and Remote Sensing
(LIght Detection And Ranging) is a powerful remote sensing technology
that bounces laser pulses off the vegetation and ground as a data collection
aircraft flies across a landscape.
Stand Visualization Models
and landscape visualization models are used to communicate stand
conditions, silvicultural treatments, and forest management alternatives
to a variety of audiences.
