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.
In 2020, Yakama Nation was successful in securing the U.S. Environmental Protection Agency (EPA) Columbia River Basin Restoration Program (CRBRP) funding to begin Phase 1 of a multi-phased, multi-year project to develop a Fish Tissue and Water Quality Monitoring Program (Monitoring Program) along the approximately 600-mile length of the Middle and Upper Columbia River mainstem to assess and track status and trends of contaminants in fish, water, sediments and invertebrates from the Canadian Border to Bonneville Dam.
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.
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
The Yakama Nation is a federally recognized Tribe, pursuant to the Treaty of 1855 (12 Stat. 951), with authority to manage, protect and restore treaty resources throughout the Pacific Northwest. The Columbia River is frequently referred to and honored as "the life blood of the Yakama Nation." Currently, the Columbia River is a polluted and life-threatening environment for salmon and other aquatic resources primarily because of industrial development.
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.
Renchler’ Meadow is an important water storage area for Dry Creek, a tributary of Satus Creek, both of which support culturally important fish species. Meadows are extremely important for absorbing and slowly releasing rainfall and snowmelt to maintain summer base flows in streams. The meadows themselves support culturally important roots that are gathered for food, medicinal and ceremonial purposes by the Yakama people. Renchler's Meadow was impacted by a variety of human related activities in the past, which ultimately caused the stream channel to erode throughout the meadow.
Yakama Reservation Watershed Project (YRWP) proposed to remove a culvert on North Fork Simcoe Creek just above its confluence with Diamond Dick Creek within the closed area of the Yakama Nation Reservation. The culvert was undersized and a seasonal barrier to ESA listed Middle Columbia River Steelhead (MCRS). At high flow, the culvert became clogged and temporarily re-routed water down the adjacent road stranding fish and damaging the road surface.
Yakama Nation Fisheries (YNF) removed a six-foot diameter culvert and the concrete fill material associated with it. The culvert was located on Toppenish Creek (watershed area is greater than 200 sq. mi.) near the confluence of Toppenish and Simcoe Creeks, approximately ½ mile west of Brownstown Rd. The culvert is on property recently acquired by the Yakama Nation.
A reach assessment of the area adjacent to the culverts was conducted to identify any risks such as potential head-cuts or areas primed for avulsion.
This project was implemented to assist in managing the migration of cattle from low elevations in the spring to higher elevations in the early summer. Prior to the project, upon cattle turnout on May 1, cattle would quickly travel approximately 25 miles to the headwater meadows of Satus and Toppenish Creeks. Livestock immediately impacted several important high elevation meadows, by overgrazing and by creating hardened cattle trails. These impacts further increased channel incision and bank erosion in these areas..
