    Queets Vegetation Management United States Environmental Assessment Department of Agriculture Olympic National Forest Forest Service Jefferson County, Washington Pacific Northwest Region June 2015 The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or part of an individual’s income is derived from any public assistance program. (Not all prohibited bases apply to all programs.) Persons with disabilities who require alternative means for communication of program information (Braille, large print, audiotape, etc.) should contact USDA's TARGET Center at (202) 720-2600 (voice and TDD). To file a complaint of discrimination, write to USDA, Director, Office of Civil Rights, 1400 Independence Avenue, S.W., Washington, D.C. 20250-9410, or call (800) 795-3272 (voice) or (202) 720-6382 (TDD). USDA is an equal opportunity provider and employer. Abstract: This Environmental Assessment documents the proposed action, two alternatives to the proposed action, and the no action alternative considered for commercially thinning timber; conducting road construction, reconstruction, and maintenance; treating activity-generated slash (fuels); and implementing connected actions within the Late-Successional Reserve, Adaptive Management Area, and Riparian Reserve land allocations of the Queets River watershed on the Olympic National Forest, Pacific Ranger District. The Queets Vegetation Management project proposed treatment units are located within the Late-Successional Reserve and Adaptive Management Area land allocations, and also include Riparian Reserves which overlay these other land allocations.

  • 2016 State of Our Watersheds Report Queets – Chehalis Basins
    2016 State of Our Watersheds Report Queets – Chehalis Basins he evidence is abundantly clear. We know how Tto manage our fish. We understand sustain- ability. The problems fish are facing are not of our making. But we are definitely a big part of the solution, with the work we do in habitat res- toration and protection, good management and education. – FAWN SHARp, PRESIDENT QUINAULT INDIAN NATION Quinault Indian Nation The Quinault Indian Nation (QIN) consists of the Quinault and Queets tribes and descendants of five other coastal tribes: Quileute, Hoh, Che- halis, Chinook and Cowlitz. Quinault ancestors lived on a major physical and cultural dividing line. Beaches to the south are wide and sandy, while to the north, they are rugged and cliff- lined. Quinault people shared in the cultures of the people to the south as well as those to the Seattle north. Living in family groups in longhouses up and down the river, they were sustained by the land and by trade with neighboring tribes. Salmon runs, abundant sea mammals, wildlife and forests provided substantial material and spiritual wealth. A great store of knowledge about plants and their uses helped provide for the people. The western red-cedar, the “tree of life,” provided logs for canoes, bark for clothing, split boards for houses and more. The Quinault are the Canoe People, the people of the cedar tree. Tribal headquarters are located in Taholah, Washington. 190 Quinault Indian Nation Queets – Quinault – Chehalis Basins The Quinault Indian Nation’s Area of Interest for this report covers three Water Resource Inventory Areas (WRIAs) includ- ing the Queets-Quinault basin (WRIA 21) and Chehalis basin (WRIAs 22 and 23).

Speaker Oregon State University,Corvallis, Oregon :]: ABSTRACT Four distinct running-water habitats are defined and examined on the South Fork Hoh River and Upper Queets River-main river channel, river off-channel areas, terrace tributaries, and valley-wall tributaries. Speciescompositions, densities, and total fish biomassesare distinctly different for each habitat examined. Habitat formed by the main river channel and its tributaries is controlled by the valley terrace structure and the modifyingeffects of large woody debris. Large woody debris is important to all habitats regardless of size of stream. Without large wood, spawning and rearing-habitat quality would be poorer, even in the large, sediment-rich main channel. large wood-capped side channels had eight times the coho salmon (Oncorhynchus kisutch) densities as side channels without debris.

An important motivation for understanding orogenesis here, and throughout the Coast Range, is the concern about the relationship of active deformation to seismic hazards associated with the Cascadia subduction zone. There is also much interest in apportioning the nature of the deformation, whether cyclic or permanent, whether it involves mainly shortening parallel or normal to the margin, and how the deformation on the pro- versus retrowedge sides of the orogen compare. Pre-Holocene stratigraphy and structure provide the only records of suffi cient duration to separate long-term permanent deformation from earthquake-cycle elastic deformation.
