Description

Construction of the Dalles, Bonneville, McNary, and John Day Dams on the Columbia River by the federal government resulted in a substantial loss of riparian bottomland along the Columbia River. Impacts associated with the Mid-Columbia Projects were assessed for several wildlife species using the Habitat Evaluation Procedures (HEP) developed by the U.S. Fish and Wildlife Service (USDI-FWS 1980). The studies documented the loss of riparian habitat and established a baseline against which mitigation measures could be developed (USDI-FWS 1990 and USDE-BPA 1990). The impact assessments established a mitigation goal, a portion of which would be satisfied by the creation, restoration, ... continued below

Description

Construction of the Dalles, Bonneville, McNary, and John Day Dams on the Columbia River by the federal government resulted in a substantial loss of riparian bottomland along the Columbia River. Impacts associated with the Mid-Columbia Projects were assessed for several wildlife species using the Habitat Evaluation Procedures (HEP) developed by the U.S. Fish and Wildlife Service (USDI-FWS 1980). The studies documented the loss of riparian habitat and established a baseline against which mitigation measures could be developed (USDI-FWS 1990 and USDE-BPA 1990). The impact assessments established a mitigation goal, a portion of which would be satisfied by the creation, restoration, and enhancement of riparian lands on tributaries to the Columbia River, including the Yakima Valley. The Yakama Nation (YN), the Northwest Power Planning Council, and the Bonneville Power Administration have agreed that the Yakama Nation would be funded to implement habitat restoration on lands within and adjacent to their reservation. Some of the targeted lands are owned by the Yakama Nation, some are trust lands, and some lands have been in private ownership. Since the early 1990s, the Yakama Nation has been in the process of assembling riparian lands into Wildlife Management Areas, and restoring natural hydrology and natural cover-types on these lands. The Northwest Power Planning Council, through the Bonneville Power Administration, has supported the program. HEP studies were performed by the Yakama Nation in 1990 (Bich et al. 1991) to establish baseline conditions and inventory wildlife habitat at the initiation of the restoration project. The 1990 HEP used a simplified version of the HEP to quantify baseline conditions. The present assessment is designed to evaluate the progress of the mitigation plan in meeting its stated goals. The 1999 HEP assessment has two distinct tasks: (1) Evaluation of the mitigation plan as currently implemented using the simplified YN HEP methodologies for the Wildlife Management Areas; and (2) Evaluation of the simplified YN HEP methodologies as a means of measuring mitigation progress.
