R6-NR-ECOL-TP-03-04 To My Packers Field Assistants Access to remote subalpine portions of the mountains often required special assistance from packers for the equipment, gear, and supplies Over the years there have been many who have assisted me with necessary for 8 to 10-day hitches. Although the majority of the plots were access into remote subalpine portions of the mountains enabling me to established far and high above base camps, these experienced packers conduct field studies. Others have accompanied me to assist with also pitched-in to scribe the data, dig a soil pit, or jiffy-up a tasty meal.

Photo Credits All photographic images were created by the author (except as noted on the printed photograph). Special thanks go out to Bruce Barnes and Elaine Urban for helping locate high quality images of indicator species that were lacking. Line Drawings: The pen and ink drawings of plant parts have been used by permission of the University of Washington Press (Seattle, Washington) and were copied from “Vascular Plants of the Pacific Northwest” (Volumes 1-5) by C.L. Hitchcock, A. Cronquist, M. Ownbey, and J.W. Thompson. I began my journey into the alpine wonderlands of the inland Pacific Northwest about the time this photo was taken in 1964. My initial goal was to climb the twenty highest peaks of the Wallowa Mountains and learn some plants along the way. Over the ensuing years I continued climbing to the summits of many mountains and spent quality time with the subalpine and alpine flora. In 1964, another Johnson (Lyndon Baines) signed the Wilderness Act in Washington, D.C. and the Eagle Cap Wilderness was created. I became one of the first wilderness guards in the new Eagle Cap Wilderness. As the Lakes Basin Guard, the subalpine forests, alpine ridges, and soaring peaks were my "office." I continued to climb, but my interests were shifting to the flora. I was inquisitive. I spent my nights keying unknown plants by lantern light at my Douglas Lake camp. A two-year sabbatical from northeast Oregon began in 1967, when I went to Chile with the Peace Corps. This experience heightened my interest in subalpine vegetation, when my culminating year was spent studying, mapping, and documenting the subalpine plant communities in the high southern Andes Mountains. This would propel me to graduate studies at the University of Idaho where plant ecology would be my focus. In 1972, I became familiar with another northeast Oregon wilderness area as a member of the Strawberry Mountain Wilderness trail crew. This experience provided me with more opportunities to learn new subalpine plants and begin an understanding of the plant communities in which they occurred. My goals were now changing from mountain climbing and floral identification, to a desire to differentiate the various plant communities, and to better understand the elements influencing where a particular plant grows and establishes its residency. In 1977, following advanced studies in plant ecology at Oregon State University, I became the first plant ecologist for the Malheur, Umatilla, and Wallowa-Whitman National Forests. In 1980, as part of the Forest Service "potential plant community classification effort for Washington and Oregon," I began systematically sampling the subalpine and alpine ecosystems of the Wallowa, Seven Devils, and Blue Mountains. This book culminates my multi-year effort to seek, learn, document, and analyze the alpine and subalpine plant community information gathered from many trips into the high mountains. Hopefully the information contained in the following pages will assist managers in maintaining and enhancing these fragile ecosystems, and help visitors using this book better understand and appreciate the magnificent diversity of plants and plant communities that exist in these high altitude landscapes.

In 1987 some of the higher elevation plant communities of the Wallowa and Seven Devils Mountains were included in the classification and management guide Plant Associations of the Wallowa-Snake Province (Johnson and Simon 1987). The higher elevation vegetation of the Blue Mountains was incorporated in the classification and management guide Plant Associations of the Blue and Ochoco Mountains (Johnson and Clausnitzer 1992). The remote topography, difficult accessibility, and high variation in types of vegetation and plant communities limited the information and data available for those publications. In 1993, and continuing through 2002, an effort was made to bolster the number of plots providing data about subalpine and alpine vegetation and to visit a greater representation of high-elevation landscapes to provide better information for land managers, specialists, scientists, and recreationists. In all, 582 permanent plots have been installed for the purposes of this study and are now available for documenting change in the future. The objectives of this study were to complete the upland classification of vegetation for subalpine and alpine environments, provide a guide for managers to use in determining vegetation types and their potential based on environmental factors, and establish a scientific basis for

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

DATE: November 2009 APPROVED BY: DATE: _____________ Name, Forest Botanist, Lake Tahoe Basin Management Unit SUMMARY OF EFFECTS DETERMINATION AND MANAGEMENT RECOMMENDATIONS AND/OR REQUIREMENTS One population of a special-status bryophyte, three-ranked hump-moss (Meesia triquetra), was observed in the survey area during surveys on June 30, 2008 and August 28, 2008. The proposed action will not affect the moss because the population is located outside the project area where no action is planned. The following species of invasive or noxious weeds were identified during surveys of the Project area: cheatgrass (Bromus tectorum); bullthistle (Cirsium vulgare); Klamathweed (Hypericum perforatum); oxe-eye daisy (Leucanthemum vulgare); and common mullein (Verbascum Thapsus). The threat posed by these weed populations would not increase if the proposed action is implemented. An inventory and assessment of invasive and noxious weeds in the survey area is presented in the Noxious Weed Risk Assessment for the Upper Truckee River Sunset Stables Restoration Project (ENTRIX 2009). Based on the description of the proposed action and the evaluation contained herein, we have determined the following: There would be no significant effect to plant species listed as threatened, endangered, proposed for listing, or candidates under the Endangered Species Act of 1973, as amended (ESA), administered by the U.S.

In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes.
