Background
What is Five
Rivers?
A 76,000-acre watershed in the Oregon Coast
Range with Forest Service, BLM, and private lands;
An operational, landscape-management plan
for 32,000 acres of Forest Service land in the watershed;
A 16,000-acre landscape experiment with
four replications randomly assigned to 1,300-acre “roadsheds;”
A 76,000-acre retrospective study learning
from past actions, monitoring, and natural disturbances; and
A partnership of the Pacific Northwest
Research Station, Oregon State University, the Siuslaw NF, and the Salem BLM.
What is the Five Rivers
landscape experiment?
A management experiment that demonstrates
what active adaptive management is, as called for in the Northwest Forest
Plan;
Three pathways to achieve the
late-successional and riparian reserve objectives will be rigorously
compared:
Passive–-decommissions roads, allows
existing plantations and aquatic systems to achieve objectives on their
own;
Continuous–-maintains roads open and
thins plantations and restores streams frequently and at low intensity;
and
Pulsed–-thins plantations and restores streams
aggressively, then closes roads for 30 years before reopening them for
further
management.
What will be done?
Collect pretreatment data and install the
landscape experiment;
Monitor to see how well the three pathways
meet the Plan;
Create an intensive GIS with all known,
previously collected data and air-photo layers for the watershed; and
Study effects of ecosystem-development
history (interactions of people and nature) on current productivity and
biodiversity.
What are the expected
outcomes?
An analysis of the relations between forest
history and current biodiversity and productivity;
An understanding of process across scales
(0.1-acre plots, 40-acre units, and 1300-acre roadsheds) and boundaries;
The role of past disturbance in present and
future stand behavior;
Improved forest management through
time;
New insights into the role of roads in
managed forests; and
An extension to regional scale through
collaboration with CLAMS (http://www.fsl.orst.edu/clams/).
Who benefits?
Public and private land managers who are
using adaptive management;
Local governments and watershed
organizations; and
Land managers in other regions.
