Collaboration Research Articles
Below you will find research articles on White-headed Woodpecker ecology/biology that we have co-authored with other researchers who started the research through other institutions. We are grateful to have been able to work with them and we hope you find the information in these articles interesting and noteworthy.
Gray Flycatcher Nest Survival
The Gray Flycatcher (Empidonax wrightii) was found to only occur as a breeding species in WA in the 1970s. Since then, no detailed information existed on habitats used by Gray Flycatchers for breeding. To address this information gap, we initiated as study to investigate Gray Flycatcher nest survival in managed ponderosa pine (Pinus ponderosa) forests.
Yakama Nation Superfund Section Technical Consultant RFQ
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.
Western Bluebird Nest-site Characteristics in Managed Ponderosa Pine Forests
We studied the nest-site characteristics of Western Bluebirds nesting in natural tree cavities in burned and unburned logged ponderosa pine forests along the east-slope of the Cascade Range of Washington, 2003–2008 and 2010. We compared 13 bluebird nest-site habitat variables between burned and unburned stands by assessing overlap in 95% CI.
Hairy and White-headed Woodpecker Nestling Provisioning In Managed Ponderosa Pine Forests
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
Pacific Lamprey Project
The Yakama Nation is working to restore natural production of Pacific lamprey to a level that will provide robust species abundance, significant ecological contributions and meaningful harvest within the Yakama Nations Ceded Lands and in the Usual and Accustomed areas.
Yakima Basin Steelhead Kelt Reconditioning
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.
Yakima Basin steelhead population monitoring
This project expands research, monitoring, and evaluation (RM&E) activities conducted by the co-managers in the Yakima Basin (Yakama Nation and Washington Department of Fish and Wildlife-WDFW) to better evaluate viable salmonid population (VSP) parameters (abundance, productivity, spatial structure, and diversity) for Yakima River steelhead (Oncorhynchus mykiss) populations. It was developed to fill critical monitoring gaps identified in the 2009 Columbia Basin monitoring strat
Yakima Klickitat Fisheries Project (YKFP)
To restore sustainable and harvestable populations of salmon, steelhead, and other at-risk species, the YKFP is evaluating all stocks historically present in the Yakima and Klickitat Subbasins and, using principles of adaptive management, is applying a combination of habitat protection and restoration, as well as hatchery supplementation or reintroduction strategies to address limiting factors.
