The INR worked with the Oregon Department of Environmental Quality, the Oregon Department of Fish and Wildlife, and the federal Environmental Protection Agency to propose an integrated study design for collecting data on Native Fish, Indexes of Biotic Integrity and Water Quality, and Riparian Area Condition and Function. Estimated costs are provided at various scales. The reporting time frame will depend on the indicator and the sample design. A reporting time frame of 5–10 years would allow ecosystems to respond perceptibly to both natural disturbances and management activities and policies. Shorter reporting periods are likely to reveal very little change and yet increase costs.
