  • Threatened and Endangered Species Coorespondence
    APPENDIXF THREATENED AND ENDANGERED SPECIES CORRESPONDENCE INTRODUCTION Forest Service policy regarding Biological Evaluaitons is summarized in Forest Service Manual (FSM) 2672.4. The intent of the Bilogical Evaluation process is to assess the potential impacts of propsed management activities, and ensure that such activities will not jeopardize the continued existence of: 1. Species listed, or proposed to be listed, as Engangered or Threatened by the U. S. Fish and Wildlife Service and 2. Species designated as sensitive by the Regional Forester. AFFECTED ENVIRONMENT Project Area The Sioux Ranger District proposes to update allotment management plans for 11 domestic livestock allotments on National Forest System lands in the North and South Cave Hills and East Short Pine land units. The decision associated with this proposal and analysis wi" determine where livestock can graze, when grazing wi" occur and what specific guidelines will be established to regulate the intensity (timing and duration) of grazing. The analysis area includes about 17,700 National Forest acres. The climate is continental and semi-arid, with large seasonal and daily temperature variations being common. Most of the rainfall during the summer is from thunderstorms; flash flooding can occur form the more severe thunderstorms. Streamflow is erratic with most streams being intermittant in nature. Ecological units include hardwood draws, Ponderosa bench and slope, upland, rolling, and table top grassland, rockland, and rimrocks. Detailed information regarding plant community composition and location is found elsewhere in the environmental analysis for this proposed action. Field surveys have been conducted within or adjacent to the project area by Linda Spencer, Kim Reid, Jeff DiBenedetto, and Tim McGarvey during the 2001 field season (s).

  • Washington Flora Checklist a Checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium
    Washington Flora Checklist A checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium The Washington Flora Checklist aims to be a complete list of the native and naturalized vascular plants of Washington State, with current classifications, nomenclature and synonymy. The checklist currently contains 3,929 terminal taxa (species, subspecies, and varieties). Taxa included in the checklist: * Native taxa whether extant, extirpated, or extinct. * Exotic taxa that are naturalized, escaped from cultivation, or persisting wild. * Waifs (e.g., ballast plants, escaped crop plants) and other scarcely collected exotics. * Interspecific hybrids that are frequent or self-maintaining. * Some unnamed taxa in the process of being described. Family classifications follow APG IV for angiosperms, PPG I (J. Syst. Evol. 54:563?603. 2016.) for pteridophytes, and Christenhusz et al. (Phytotaxa 19:55?70. 2011.) for gymnosperms, with a few exceptions. Nomenclature and synonymy at the rank of genus and below follows the 2nd Edition of the Flora of the Pacific Northwest except where superceded by new information. Accepted names are indicated with blue font; synonyms with black font. Native species and infraspecies are marked with boldface font. Please note: This is a working checklist, continuously updated. Use it at your discretion. Created from the Washington Flora Checklist Database on September 17th, 2018 at 9:47pm PST.

    Fire Effects Information System (FEIS) FEIS Home Page SPECIES: Atriplex gardneri Table of Contents SUMMARY INTRODUCTORY DISTRIBUTION AND OCCURRENCE BOTANICAL AND ECOLOGICAL CHARACTERISTICS FIRE EFFECTS AND MANAGEMENT MANAGEMENT CONSIDERATIONS APPENDIX REFERENCES Figure 1—Gardner's saltbush fruits. Image by Matt Lavin from Bozeman, Montana, USA. Used with permission. SUMMARY SPECIES: Atriplex gardneri This Species Review summarizes information on the fire effects and related ecology of Gardner's saltbush that was available in the scientific literature as of 2020. Gardner's saltbush is a member of a complex of taxa that are intermediate between herbaceous and shrub forms (i.e., half-shrubs). Taxa within the complex hybridize readily, confounding species identification and classification. There is disagreement among systematists as to placement of taxa sometimes classified as Gardner's saltbush. https://www.fs.fed.us/database/feis/plants/shrub/atrgar/all.html 1/25 Gardner's saltbush is distributed from southeastern British Columbia east to southwestern Manitoba and south to Colorado. It grows in semiarid and temperate climates and is drought and salt tolerant. It is common to dominant on sites with fine-textured, saline soils, especially clay flats and basins. Gardner's saltbush dominates or codominates many salt desert shrublands, and it is a component of some sagebrush and mixed-grass prairie communities. Gardner's saltbush reproduces after fire and other top-killing events primarily by sprouting from the root crown and roots. It also reproduces from seed, from persistent aerial and soil-stored seed banks. Its fruits may remain viable on the plant for 1 to 2 years. The seeds are dormant upon dispersal, with high levels of dormancy and complex, multiple mechanisms of dormancy.

This information represents what was known at the end of the 1994 field season. These maps may not represent the most recent information on distribution and range for these taxa but it does illustrate geographic distribution across the assessment area. For many of these species, this is the first time information has been compiled on this scale. For the continued viability of many of these taxa, it is imperative that we begin to manage for them across their range and across administrative boundaries. Of the 173 taxa analyzed, there are maps for 153 taxa. For those taxa that were not tracked by heritage programs, we were not able to generate range maps.

  • A Botanical Guide to Special Places in the Pryor Mountains Jennifer Lyman, Ph.D., Botany, Kelsey Flathers and Simone Durney, Students
    A Botanical Guide to Special Places in the Pryor Mountains Jennifer Lyman, Ph.D., Botany, Kelsey Flathers and Simone Durney, Students Introduction: The plant-life of the Pryor Mountains is a botanist’s delight and a sadly undervalued part of Montana’s natural landscape. The South Pryor Mountains alone offer 5,000 feet of vertical relief that supports more than 25 plant communities (interacting associations of plant species populations). These communities extend from alluvial fans that support varied shrublands to cushion plant grasslands above 8,000 feet. Several plant communities, (Utah Juniper/mountain mahogany; Nuttall’s saltbush/Budsage; and Limber pine/Utah Juniper), are designated as globally rare by the Montana Natural Heritage Program (MNHP). And the North Pryor region, in the Punchbowl area, offers a beautiful example of aspen forest encompassing an understory of native shrubs and forbs. The aspen stands open onto sagebrush meadows with views of the rugged limestone cliffs of the Pryor’s northern front. The students (Flathers and Durney) quickly grew to love the Pryor Mountain range because of its spectacular topography, the diversity of plant species, and the unusual level of rare and endemic species and plant communities. When Dr. Lyman proposed that they use their studies to create a Botanical Guide to Special Places in the Pryor Mountains, they jumped at the opportunity. The purpose of the guide is to encourage exploration of the Pryor Mountains in much the same way that naturalists have observed the world around them for hundreds of years - to observe closely, to connect plant life to the environment in which it thrives, and to appreciate the variety of life that subsists in landscapes shaped and reshaped by millions of years of geologic change.
