the volume and quality of wood produced under an ecologically
sustainable landscape management plan in the Oregon Cascade Mountains
- The system of riparian and late successional
reserves established under the Northwest Forest Plan (NWFP) segregate
the landscape into a complex network of use categories making
forest operations difficult and expensive.
- Landscape management models that mimic
natural disturbances may achieve the
NWFP objectives without
intricate reserves and at lower costs.
- Little is known about the trade-offs
among ecological, social, and economic
The Ecologically Sustainable Production of Forest Resources (ESP)
Team at the PNW Station is working in conjunction with the Central
Cascades Adaptive Management Area to evaluate the relative costs
and wood product potential of a disturbance based plan for meeting
the NWFP Aquatic Conservation Strategy. The analysis is based
on the Blue River Landscape Management Plan developed by the
Ecological Processes Program at the PNW Station. It uses the
Landscape Management System (LMS) to simulate stand growth and
structure to compare a range of ecological, social, and economic
values across the watershed through time.
- Current vegetation inventory data has been collected for
980 stands in a 59,000-acre watershed and entered into the LMS
computer model used for analysis.
- Development of thinning prescriptions and treatment schedules
- Simulation of stand growth with the Forest Vegetation Simulator
model has begun.
- A computer program to evaluate wood quality based on tree
and log characteristics is under development.
