The geographic scope of this project includes five wilderness areas in the central Cascade Range of Oregon, totaling about 536,368 acres: Mount Jefferson Wilderness, Three Sisters Wilderness, Mount Washington Wilderness, and Diamond Peak Wilderness are co-managed by the Deschutes and Willamette National Forests; Waldo Lake Wilderness is managed entirely by the Willamette National Forest (see Figure 1 and Figure 2). These wilderness areas provide a great diversity of outdoor recreation opportunities; however, they continue to face increasing recreational demands that can degrade natural resources and impact the wilderness experience. The wilderness areas of the Central Cascades in Oregon were legislated in 1964, 1968 and 1984: • Mount Washington Wilderness, Three Sisters Wilderness, and Diamond Peak Wilderness- Designated by Public Law 88-577- Wilderness Act of 1964. • Mount Jefferson Wilderness- Designated by Public Law 90-548 in 1968. • Waldo Lake Wilderness designated and additions made to Mount Jefferson, Mount Washington and Three Sisters- Public Law 98-328, Oregon Wilderness Act of 1984. As part of the National Wilderness Preservation System, Congressionally-designated wilderness areas are special places accorded a very high level of protection. The Wilderness Act sets wilderness apart from other public lands and establishes a mission objective for the agency to preserve wilderness character. Planning Background Comprehensive planning for visitor use management in the Central Cascades Wilderness areas through the NEPA process has not occurred since the early 1990s. A 1991 Decision Notice authorized the creation of a self-issue permit system across the Mt. Jefferson, Mt. Washington, and Three Sisters Wilderness Areas. The permit was intended to improve education of visitors and to collect data on numbers of visitors and the types and areas of use. Wilderness permits are currently required from Memorial Day until October 31st. The 1991 NEPA process and decision also initiated the formation of a wilderness focus group which looked at the permit data collected through two seasons and then made recommendations on management strategies. The wilderness focus group developed an implementation plan that detailed a number of actions that were subsequently

This report was developed from data gathered by the FIA in eastern Oregon’s forests in 1998 and 1999, and has been supplemented by inventories from Oregon’s national forests between 1993 and 1996.This report and other analyses of FIA inventory data will be extremely useful as we evaluate fire management strategies, opportunities for improving rural economies, and other elements of forest management in eastern Oregon.We greatly appreciate FIA’s willingness to work with the researchers, analysts, policymakers, and the general public to collect, analyze, and distrib- ute information about Oregon’s forests.

Monitoring wolverines in northeast Oregon – 2011. Final Report. The Wolverine Foundation, Inc., Kuna, Idaho, USA. 2 INTRODUCTION The Oregon Conservation Strategy lists “species data gaps” and “research and monitoring needs” for some species where basic information on occurrence and habitat associations are not known (ODFW 2006; pages 367-368). For the Blue Mountains, East Cascades, and West Cascades Ecoregions of Oregon, the Strategy lists wolverine as a species for which status is unknown but habitat may be suitable to support wolverines. ODFW lists the wolverine as Threatened in Oregon and the USFWS has recently placed the species on the candidate list under the federal Endangered Species Act. Wolverine range in the contiguous United States had contracted substantially by the mid-1900s, probably because of high levels of human-caused mortality and very low immigration rates (Aubry et al.

  • Newsletter Newsletter of the Pacific Northwest Forest Service Retirees — Fall 2011
    OldSmokeys Newsletter Newsletter of the Pacific Northwest Forest Service Retirees — Fall 2011 President’s Message—John Berry It was good to see and talk with so many of you at the Summer Picnic. Some I had not seen for years and I wished there had been more time to catch up. And it was a pleasure to see the great attendance by Regional Office and Mt. Hood National Forest leaders. It means a lot to have Regional Forester and OldSmokey Kent Connaughton and Forest Supervisor Chris Worth attend our functions. Both are very approachable and great listeners. It’s good to see the Region is in good hands. A big thanks to Mike Ash for donating one of his beautiful wood bowls for the raffle to support the PNWFSA Emergency Relief Fund. And, no, I did not bribe Kent Connaughton to draw my wife’s ticket! Thanks to Rick Larson for reserving the picnic area. Thanks to Bev Pratt, Mary Moyer, and Deb Warren for welcoming and doing the name tags. Of course, Dave Dalton and his crew did a great job of catering. Also, check out Paul Enberg’s and John Poppino’s photos on our website at <www.oldsmokeys.org>. The picnic reminds me what it means to be a member of the “Forest Service Family.” Next to my own family, the Forest Service has been the single most important factor in my life. The Forest Service offered me incredible career opportunities as it p rovided outstanding education and training, good pay, and a retirement annuity that allows my wife and me to live comfortably.

  • Geology of the Northern Part of the Southeast Three Sisters
    AN ABSTRACT OF THE THESIS OF Karl C. Wozniak for the degree of Master of Science the Department cf Geology presented on February 8, 1982 Title: Geology of the Northern Part of the Southeast Three Sisters Quadrangle, Oregon Redacted for Privacy Abstract approved: E. M. Taylorc--_, The northern part of the Southeast Three Sisters quadrangle strad- dles the crest of the central High Cascades of Oregon. The area is covered by Pleistocene and Holocene volcanic and volcaniclastic rocks that were extruded from a number of composite cones, shield volcanoes, and cinder cones. The principal eruptive centers include Sphinx Butte, The Wife, The Husband, and South Sister volcanoes. Sphinx Butte, The Wife, and The Husband are typical High Cascade shield and composite vol- canoes whose compositions are limited to basalt and basaltic andesite. South Sister is a complex composite volcano composed of a diverse assem- blage of rocks. In contrast with earlier studies, the present investi- gation finds that South Sister is not a simple accumulation of andesite and dacite lavas; nor does the eruptive sequence display obvious evolu- tionary trends or late stage divergence to basalt and rhyolite. Rather, the field relations indicate that magmas of diverse composition have been extruded from South Sister vents throughout the lifespan of this volcano. The compositional variation at South Sister is. atypical of the Oregon High Cascade platform. This variation, however, represents part of a continued pattern of late Pliocene and Pleistocene magmatic diver- sity in a local region that includes Middle Sister, South Sister, and Broken Top volcanoes. Regional and local geologic constraints combined with chemical and petrographic criteria indicate that a local subcrustal process probably produced the magmas extruded fromSouth Sister, whereas a regional subcrustal process probably producedthe magmas extruded from Sphinx Butte, The Wife, and The Husband.
