Ten new taxa were located: Anemone tetonensis; Antennaria monocephala; Claytonia megarhiza; Draba crassa; Draba globosa; Erigeron radicatus; Minuartia austromontana; Oxytropis deflexa var. foliolosa; Parnassia kotzebuei; and Ranunculus pygmaeus. The exact determination of two Draba specimens, one collected at Cutoff Mountain and another at Quadrant Mountain, is still ongoing with some of the Draba specimens sent to the Missouri Botanical Garden to be annotated by Dr. Ihsan Al- Shehbaz. Additionally, Achnatherum pinetorum was confirmed to occur in the southern Gallatin Range. v Acknowledgments This project was partially funded through the NPS Greater Yellowstone Network Inventory Program. The author would like to thank the NPS inventory steering committee, Rick Lasko, Mason Reid, Ann Rodman, and Kathy Tonnessen for their help conducting the inventory workshop that identified the need for an alpine plant inventory in Yellowstone National Park. The author would also like to thank Cathie Jean and Lane Cameron from the Greater Yellowstone Network for their help on planning the vascular plant inventory. Gallatin National Forest rangers were immensely helpful with the corral operation and fire cache, especially Wally Wines, Dave Elwood, Monty Simenson, Brian Helms, Bonnie Gafney, and Wendy Hafer. The field crews that scrambled here and there included Heidi Anderson, Ken Aho, Vicki Pecha, Elizabeth Crowe, Cheryl Jaworowski, and John David Sacklin. Finally, Mary Hektner was a tower of strength in shepherding the logistics through the years. vi Introduction One of the goals of the Inventory and Monitoring program of the National Park Service is to have at least a ninety-percent knowledge of the vascular plants of each park unit. The knowledge of the vascular plant flora of Yellowstone National Park is extensive with collections dating back to 1870, but most of the collecting has been focused on areas easily

  • 2004 Bark Beetles
    BARK BEETLE CONDITIONS NORTHERN REGION 2004 Ken Gibson USDA Forest Service Northern Region Forest Health Protection Missoula Field Office December 2004 BARK BEETLE CONDITIONS Northern Region 2004 REGIONAL SUMMARY Although late fall has turned out to be atypically dry, most of the Region received above normal amounts of precipitation during calendar year 2004. Most of Montana, and especially the eastern portions, have not completely broken out of the 4- to 5-year drought; however, growing conditions for most bark beetle hosts improved markedly throughout the Region. Despite improved conditions, long-term drought affects are not easily overcome. Too, many bark beetle species are at extremely high levels and will not respond to improved host conditions for a year or so. Those latter two factors combined to result in an increase in infested area by most bark beetle species across the Region. Unfortunately, less-than-optimal weather conditions late in the season prevented aerial survey of all beetle-infested areas. Approximately 85% of the forested portions of the 24 reporting areas were flown. While some areas appeared to be less impacted, for most of the Region, and particularly Montana; both aerial and ground-collected data showed still- increasing bark beetle infestations for most species. Mountain pine beetle-infested areas increased in many locations surveyed; however, in some locations, intensity of beetle-caused mortality is declining due to host depletion. Decreases in infested area recorded on the Lolo National Forest (NF), however, is a reflection of the amount of area flown—not necessarily an indication that the outbreak, overall, is waning. In total, considerably more infested acres were recorded in 2004 than in 2003; despite some heavily infested areas having not been flown.

  • Native Plant List, Pdf Format
    Appendix A: City of Bellingham Native Plant List December 2020 The City of Bellingham Native Plant List (Figure 1) includes plant species that are native to Bellingham watersheds (Figure 2). The native plant list applies to all habitat types, including riparian, upland, and wetland areas. The list was developed using specimen records from the Consortium of Pacific Northwest Herbaria and Bellingham plant checklists curated by Don Knoke, a volunteer at the University of Washington Herbarium. To improve plant establishment and protect the genetic resources of our local plant populations, the City recommends using native plants that were grown from seeds or cuttings collected from the Puget Trough Ecoregion (Figure 3). Obtaining native plants grown from material collected from the Puget Trough Ecoregion will help ensure the plants are adapted to the unique environmental conditions of Bellingham watersheds and are genetically similar to our local plant populations. A more thorough discussion of the rational and selection process is provided in the City of Bellingham Public Works Department Native Plant Materials Selection Guidelines, December 2020. Figure 1.

  • Status of Plant Species of Special Concern in US Forest Service
    Status of Plant Species of Special Concern In US Forest Service Region 4 In Wyoming Report prepared for the US Forest Service By Walter Fertig Wyoming Natural Diversity Database University of Wyoming PO Box 3381 Laramie, WY 82071 20 January 2000 INTRODUCTION The US Forest Service is directed by the Endangered Species Act (ESA) and internal policy (through the Forest Service Manual) to manage for listed and candidate Threatened and Endangered plant species on lands under its jurisdiction. The Intermountain Region of the Forest Service (USFS Region 4) has developed a Sensitive species policy to address the management needs of rare plants that might qualify for listing under the ESA (Joslin 1994). The objective of this policy is to prevent Forest Service actions from contributing to the further endangerment of Sensitive species and their subsequent listing under the ESA. In addition, the Forest Service is required to manage for other rare species and biological diversity under provisions of the National Forest Management Act. The current Sensitive plant species list for Region 4 (covering Ashley, Bridger-Teton, Caribou, Targhee, and Wasatch-Cache National Forests and Flaming Gorge National Recreation Area in Wyoming) was last revised in 1994 (Joslin 1994). Field studies by botanists with the Forest Service, Rocky Mountain Herbarium, Wyoming Natural Diversity Database (WYNDD), and private consulting firms since 1994 have shown that several currently listed species may no longer warrant Sensitive designation, while some new species should be considered for listing. Region 4 is currently reviewing its Sensitive plant list and criteria for listing. This report has been prepared to provide baseline information on the statewide distribution and abundance of 127 plants listed as “species of special concern” by WYNDD (Table 1) (Fertig and Beauvais 1999).

  • Sensitive and Rare Plant Species Inventory in the Salt River and Wyoming Ranges, Bridger-Teton National Forest
    Sensitive and Rare Plant Species Inventory in the Salt River and Wyoming Ranges, Bridger-Teton National Forest Prepared for Bridger-Teton National Forest P.O. Box 1888 Jackson, WY 83001 by Bonnie Heidel Wyoming Natural Diversity Database University of Wyoming Dept 3381, 1000 E. University Avenue University of Wyoming Laramie, WY 21 February 2012 Cooperative Agreement No. 07-CS-11040300-019 ABSTRACT Three sensitive and two other Wyoming species of concern were inventoried in the Wyoming and Salt River Ranges at over 20 locations. The results provided a significant set of trend data for Payson’s milkvetch (Astragalus paysonii), expanded the known distribution of Robbin’s milkvetch (Astragalus robbinsii var. minor), and relocated and expanded the local distributions of three calciphilic species at select sites as a springboard for expanded surveys. Results to date are presented with the rest of species’ information for sensitive species program reference. This report is submitted as an interim report representing the format of a final report. Tentative priorities for 2012 work include new Payson’s milkvetch surveys in major recent wildfires, and expanded Rockcress draba (Draba globosa) surveys, both intended to fill key gaps in status information that contribute to maintenance of sensitive plant resources and information on the Forest. ACKNOWLEDGEMENTS All 2011 field surveys of Payson’s milkvetch (Astragalus paysonii) were conducted by Klara Varga. These and the rest of 2011 surveys built on the 2010 work of Hollis Marriott and the earlier work of she and Walter Fertig as lead botanists of Wyoming Natural Diversity Database. This project was initially coordinated by Faith Ryan (Bridger-Teton National Forest), with the current coordination and consultation of Gary Hanvey and Tyler Johnson.
