Evaluation

The Yakama Nation requests qualifications (RFQ) from engineering and consulting firms to accomplish the work elements outlined in this Request for Qualifications (RFQ) and provide technical assistance to support YNF’s work on cleaning up and restoring hazardous waste sites in the Columbia River Basin. Yakama Nation will review the response to this RFQ to establish one or more technical support contracts. This RFQ will be considered viable for contracting purposes for FY2018, 2019, and 2020.

The RFQ can be found below in the Project Downloads.

Evaluating rates of nestling provisioning by adult birds provides insight into foraging strategies and reproductive effort. In most biparental avian species, both males and females provision the young, although this task is not always shared equally between sexes. In woodpeckers (Picidae), biparental care is thought to be necessary to successfully raise offspring, resulting in social monogamy for most woodpecker species. Unlike other avian groups, such as passerines, where females generally invest more than males in raising offspring, male woodpeckers contribute significantly to raising you

Summer- and fall-run chinook were once abundant in the Yakima River Basin, but the runs were decimated as a result of historical land and water development and fisheries management practices. By 1970, the summer-run component was extirpated and the fall-run is maintained by hatchery production using out-of-basin broodstock.

Columbia River steelhead are iteroparous (able to spawn multiple times). However, as post-spawned steelhead (kelts) attempt to migrate downstream to return to the ocean, their survival is adversely affected by major dams. Therefore, an innovative approach to effectively increasing abundance and productivity of steelhead populations is to capitalize on their inherent iteroparity by reconditioning kelts.
