Adaptive Management / Adaptive Management Process
The process of gathering and using scientific research to evaluate forest management decisions and practices. Research and monitoring provide feedback to quickly validate or improve practices on the ground.
Fish that reproduce and live the first part of their lives in fresh water, then migrate to the ocean to spend their adult lives. The time in the ocean may be as short as six months or as long as seven years before the fish return to freshwater to spawn. Salmon and steelhead are anadromous fish.

Basal Area Stand Requirements
One of the performance measures used for managing riparian forests of various ages under the Forests & Fish Law. The Basal Area is the area in square feet of the cross section of tree stems including the bark, measured at 4½ feet above the ground. The stand requirements are stated as the total basal area for all of the trees on one acre of ground.
Best Management Practices

Forests & Fish Report
The Forests & Fish Report is a consensus recommendation from federal, state, county, and many tribal governments, and private forest landowners for changes in forest practices, statutes, regulations, and management systems to achieve these goals for salmon recovery:
- Provide compliance with the Endangered Species Act for aquatic and riparian-dependent species on non-federal forestland;
- Restore and maintain riparian habitat on non-federal forestland to support a harvestable supply of fish;
- Meet the requirements of the Clean Water Act for water quality on non-federal forestland; and

Tree removal in a forest stand that reduces tree density and tree-to-tree competition, encouraging increased growth of fewer, higher quality trees.
A species that is designated by the government as likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.
Total Maximum Daily Loads (TMDLs)
A TMDL or Total Maximum Daily Load is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards. A TMDL analysis usually results in an allocation of an amount of pollution that is allowed from each source so that the total does not exceed the water quality standard.Turbidity
Having sediment or foreign particles stirred up or suspended in water.
Refers to a forest that contains trees of a variety of ages and heights.Unstable Slopes
An area where there is a high potential for landslides. In the context of this website, it refers to a forested area that that is carefully managed to protect against “mass wasting,” depositing coarse sediment and woody debris into streams.US Forest Service
Established in 1905, the Forest Service is an agency of the U.S. Department of Agriculture. The Forest Service manages the public lands in national forests.
Water Quality Standards
Water quality standards are the foundation of the water quality-based control program mandated by the Clean Water Act. In Washington state, water quality standards are set by the Department of Ecology through a public process. A water quality standard consists of four basic elements:
- Designated uses of the water body (e.g., recreation, water supply, aquatic life, agriculture),
- water quality criteria to protect designated uses (numeric pollutant concentrations and narrative requirements),
- an antidegradation policy to maintain and protect existing uses and high quality waters, and
- general policies addressing implementation issues (e.g., low flows, variances, mixing zones).

A systematic procedure for characterizing watershed and ecological processes to meet specific management and social objectives. Watershed analysis is a component of ecosystem management planning applied to all of the land within a single watershed.Watershed Analysis Unit (WAU)
A watershed of approximately 30,000 acres in size designated as a specific unit under forest practices rules. Watershed analysis under state rules is usually conducted on one WAU at a time.Wetland Protection
In the context of this website, the process of managing riparian associated forested wetlands to protect riparian functions.Wetlands
Geographic areas that are frequently inundated with water and are characterized by vegetation that requires saturated or seasonally saturated soils. Examples include bogs and marshes.
Zones – Core, Inner and Outer
- Core Zone – The no-harvest area closest to a protected stream.
- Inner Zone – The area between the Core and Outer Zones, managed to retain or improve riparian forest conditions as needed to provide for fish habitat and water quality.
- Outer Zone – The area beyond the inner zone, managed to protect special riparian sites or to support riparian protection.
