Jim Uehara, (Washington Department of Fish and Wildlife) provided funding available from the U. S. Fish and Wildlife Service. Scott Deeds (U. S. Fish and Wildlife Service) provided funding for genetic sampling and analysis of native bull trout populations in the Tucannon Basin. The Asotin County Conservation District provided funding for surveys in Asotin County; special thanks to Brad Johnson. Michael Faler (U. S. Fish and Wildlife Service) provided personnel and field accommodations for Tucannon River bull trout sampling and PIT tagging with USACE funding (for USFWS activities). The Washington Department of Fish and Wildlife provided additional funding and assistance. We would like to extend thanks to the following individuals with the Washington Department of Fish and Wildlife who contributed their efforts in collecting, entering, and summarizing data: Derek Gloyn, Steve Jeffers, Larabee Miller, and Mark Lambert. We would also like to thank Carrie Bretz, Holly Stanton-Smith and Kayla Warden for their assistance with Tucannon basin sampling (U.S. Fish and Wildlife Service employees). We appreciate the draft report review and suggestions by Joe Bumgarner and Del Groat to improve this report. Dave and Sas Waldron of Western Life Outfitters provided outfitter services for bull trout sampling in the upper Tucannon River subbasin. We would also like to thank all of the private landowners and the Nez Perce Tribe for granting access to perform fieldwork on their properties. Without access to the streams on private property, significant portions of these efforts would not have been possible.

  • Stand Density Conditions for Umatilla National Forest: a Range of Variation Analysis
    WHITE PAPER F14-SO-WP-SILV-50 Stand Density Conditions for Umatilla National Forest: A Range of Variation Analysis David C. Powell; Forest Silviculturist Supervisor’s Office; Pendleton, OR Initial Version: FEBRUARY 20131 Most Recent Revision: JUNE 2013 INTRODUCTION Umatilla National Forest adopted a program-of-work (POW) process in February 2013 involving three criteria: 1. Values at risk, including human infrastructure (Johnson 2013). 2. Subwatersheds where existing stand density exceeds a range of variation for stand density. 3. Unique habitats such as old-growth forests, aspen clones, riparian habitat conserva- tion areas, and meadows (Archuleta 2013). This white paper describes a process used to assess stand density conditions for Umatilla National Forest. A Forest-wide, stand-density assessment was completed to meet project planning needs associated with criterion #2 of a POW process. This assessment uses an analytical technique called the range of variation (RV), de- fined as a range of conditions likely to have occurred in the Blue Mountains prior to Euro-American settlement in mid-1800s. A white paper (WP Silv-3) provides concepts, principles, and methods relating to range of variation (Powell 2019) – that white paper provides more information about RV. Briefly, a stand-density assessment involved 4 steps: (1) compiling a dataset charac- terizing stand density conditions for Umatilla NF, (2) stratifying density data by biophysi- cal environment, (3) completing an RV analysis by using subwatersheds as landscape units, and (4) summarizing results while also accounting for land-use restrictions. 1 White papers are internal reports; they receive only limited review. Viewpoints expressed in this paper are those of the author – they may not represent positions of USDA Forest Service.

Mid-Columbia Recovery Unit—Grande Ronde River Critical Habitat Unit 447 Bull Trout Final Critical Habitat Justification Chapter 16 U. S. Fish and Wildlife Service September 2010 Chapter 16. Grande Ronde River Critical Habitat Unit The Grande Ronde River CHU is essential to the conservation of bull trout because is supports strong bull trout populations and provides high-quality habitat to potentially expand bull trout distribution and is considered to be essential for bull trout recovery in the Mid-Columbia RU. The eleven populations in this CHU are spread over a large geographical area with multiple age classes, containing both resident and fluvial fish. This bull trout stronghold also has a prey base; connectivity with the Snake River; general distribution of bull trout throughout the habitat; and varying habitat conditions. But in several of the populations, including the Wenaha River, Lostine River, Lookingglass Creek, and Little Minam River populations, excellent habitat conditions exist; many streams and rivers are designated as Wild and Scenic Rivers and/or located within or near Wilderness areas. Two wilderness areas are designated within the Grande Ronde River basin. The Eagle Cap Wilderness is located in the Wallowa-Whitman National Forest, encompasses 146,272 (ha) (361,446 ac), and includes most of the Minam, upper Wallowa and Lostine river drainages as well as Bear Creek and Hurricane Creek and a small portion of Catherine Creek. Federal Wild and Scenic River status is designated for the Lostine and Minam Rivers and Oregon State Scenic Waterway status is designated to the Minam and Wallowa Rivers.

  • 2018 Bull Trout Redd Monitoring in the Wallowa Mountains
    2018 Bull Trout Redd Monitoring in the Wallowa Mountains Prepared by: Gretchen Sausen U.S. Fish and Wildlife Service La Grande Field Office April 8, 2019 2018 Bull Trout Redd Monitoring in the Wallowa Mountains Prepared by: Gretchen Sausen U.S. Fish and Wildlife Service La Grande Field Office April 8, 2019 ABSTRACT Bull trout were listed as threatened under the Endangered Species Act in 1998 due to declining populations. The U. S. Fish and Wildlife Service (Service) recommends monitoring bull trout in subbasins where little is known about the populations, including the Grande Ronde and Imnaha subbasins. Spawning survey data is important for determining relative abundance and distribution trends in bull trout populations. This report summarizes the 2018 bull trout spawning data collected in the Wallowa Mountains of northeast Oregon and compares this with past years’ data. Bull trout spawning surveys have been conducted on similar index areas for selected Grande Ronde and Imnaha River streams from 1999 to 2018. These surveyed streams are located within the Wallowa River/Minam River, Lookingglass Creek/Wenaha River and Imnaha River bull trout core areas. In 2018, the Wenaha and Minam Rivers, and additional locations on Big Sheep Creek were added to the regular annual redd surveys. Surveys in 2018 were conducted by the Nez Perce Tribe (NPT), the Oregon Department of Fish and Wildlife (ODFW), the Service, U.S. Forest Service (USFS), Anderson Perry, Inc., and fisheries consultants. Objectives of the survey included: (1) locate bull trout spawning areas; (2) determine redd characteristics; (3) determine bull trout timing of spawning; (4) collect spawning density data; (5) determine and compare the spatial distribution of redds along the Lostine River in 2006 through 2018; (6) document redd locations on the Wenaha, Upper Minam, Imnaha, Big Sheep, and Bear Creek in 2018; and (7) over time, use all of the data to assess local bull trout population trends and the long-term recovery of bull trout.

Movement and life history of bull trout in the Walla Walla, John Day and Grande Ronde basins Introduction This section describes work accomplished in 2000 that continued to address two objectives of this project. These objectives are 1) determine the distribution of juvenile and adult bull trout Salvelinus confluentus and habitats associated with that distribution, and 2) determine fluvial and resident bull trout life history patterns. Completion of these objectives is intended through studies of bull trout in the Grande Ronde, Walla Walla, and John Day basins. These basins were selected because they provide a variety of habitats, from relatively degraded to pristine, and bull trout populations were thought to vary from relatively depressed to robust. In all three basins we continued to monitor the movements of bull trout with radio transmitters applied in 1998 (Hemmingsen, Bellerud, Gunckel and Howell 2001) and 1999 (Hemmingsen, Gunckel and Howell 2001).

  • Draft WRIA 35-Middle Snake Watershed Plan
    18725 WRIA 35 CVR.qxp 3/31/2006 2:01 PM Page 1 MIDDLE SNAKE WATERSHED PLAN PLANNING UNIT DRAFT April 2006 Prepared by: HDR, Inc. 2805 St. Andrews Loop, Suite A Pasco, Washington 99301 Draft April 2006 Middle Snake River Watershed Watershed Plan Executive Summary The purpose of watershed planning under the Washington Watershed Management Act (WMA) is to provide a method to help achieve a balance among competing water resource demands. Water demands for commercial, industrial, residential and agricultural activities (e.g. out of stream uses) have to be balanced with instream fish habitat needs. Demands such as irrigated agriculture provide a significant economic base for the WRIA. Critical habitat for fish species listed under the federal Endangered Species Act (ESA) as well as a diversity of non-listed fish and wildlife are also dependent upon water resources. The Basin’s surface water resources also offer recreational opportunities and natural beauty for residents and visitors. Watershed Planning Process The development of a watershed plan is Phase III of voluntary watershed planning under the WMA. WMA identifies a group of “initiating governments” that are empowered to select a lead agency, apply for grant funding, determine the overall scope of planning, and convene a “Planning Unit.” The initiating governments include all counties within the WRIA, the government of the largest city or town (if applicable), the water supply utility obtaining the largest quantity of water from the WRIA, and Indian tribes with reservation lands within the management area. Funding is provided through the WMA for areas in Washington State that wish to undertake planning and specifies ground rules for use of the funding.
