A Wildlife Habitat Protection, Mitigation and Enhancement Plan for Eight Federal Hydroelectric Facilities in the Willamette River Basin: Final Report.
The development and operation of eight federal hydroelectric projects in the Willamette River Basin impacted 30,776 acres of prime wildlife habitat. This study proposes mitigative measures for the losses to wildlife and wildlife habitat resulting from these projects, under the direction of the Columbia River Basin (CRB) Fish and Wildlife Program. The CRB Fish and Wildlife Program was adopted in 1982 by the Northwest Power Planning Council, pursuant to the Northwest Power Planning Act of 1980. The proposed mitigation plan is based on the findings of loss assessments completed in 1985, that used a modified Habitat Evaluation Procedure (HEP) to assess the extent of impact to wildlife and wildlife habitat, with 24 evaluation species. The vegetative structure of the impacted habitat was broken down into three components: big game winter range, riparian habitat and old-growth forest. The mitigation plan proposes implementation of the following, over a period of 20 years: (1) purchase of cut-over timber lands to mitigate, in the long-term, for big game winter range, and portions of the riparian habitat and old-growth forest (approx. 20,000 acres); (2) purchase approximately 4,400 acres of riparian habitat along the Willamette River Greenway; and (3) three options to mitigate for the outstanding old-growth forest losses. Monitoring would be required in the early stages of the 100-year plan. The timber lands would be actively managed for elk and timber revenue could provide O and M costs over the long-term.
