    Appendix F Species List Appendix F: Species List F. Species List F.1 Lists The following list and three tables denote the bird, mammal, fish, and plant species known to occur in Arctic National Wildlife Refuge (Arctic Refuge, Refuge). F.1.1 Birds of Arctic Refuge A total of 201 bird species have been recorded on Arctic Refuge. This list describes their status and abundance. Many birds migrate outside of the Refuge in the winter, so unless otherwise noted, the information is for spring, summer, or fall. Bird names and taxonomic classification follow American Ornithologists' Union (1998). F.1.1.1 Definitions of classifications used Regions of the Refuge . Coastal Plain – The area between the coast and the Brooks Range. This area is sometimes split into coastal areas (lagoons, barrier islands, and Beaufort Sea) and inland areas (uplands near the foothills of the Brooks Range). Brooks Range – The mountains, valleys, and foothills north and south of the Continental Divide. South Side – The foothills, taiga, and boreal forest south of the Brooks Range. Status . Permanent Resident – Present throughout the year and breeds in the area. Summer Resident – Only present from May to September. Migrant – Travels through on the way to wintering or breeding areas. Breeder – Documented as a breeding species. Visitor – Present as a non-breeding species. * – Not documented. Abundance . Abundant – Very numerous in suitable habitats. Common – Very likely to be seen or heard in suitable habitats. Fairly Common – Numerous but not always present in suitable habitats. Uncommon – Occurs regularly but not always observed because of lower abundance or secretive behaviors.

The primary goal was to document greater than 90% of the vascular plant species expected to occur within the park and significantly improve our understanding of current species distributions. The inventory targeted diverse habitat types and poorly-sampled areas. The AKNHP staff visited eight diverse ecogeographic regions and sampled intensively within these regions from late June to mid-August, 2001 and late June to early July in 2003. A total of 555 specimens were collected, recorded, pressed, and curated. Of the 333 individual taxa, 172 are new records for the park and an additional 44 represent verifications of previously unverified reports. A number of finds were significant range extensions or taxa of conservation concern. Collections were made of four globally restricted species: Botrychium ascendens (G2G3-S2 AKNHP rank), Platanthera chorisiana (G3-S3), Eleocharis kamtschatica (G4-S2S3), and Salix setchelliana (G4-S3). A number of collections were made of species which are very rare in Alaska, but more widespread in western North America, such as Agoseris aurantiaca, A.

In the Garden – What's happening in our species garden? ************** Work Party and Stewardship Coming Up******* There will be a work party the first Sunday of October (October 2) from 1:30-4:30 PM at the Species Garden to the right of the clubhouse (by the climbing wall). The plan is to weed and plant in preparation for winter. If you haven’t seen the garden recently, you will be amazed at the growth especially in the alpine plants. ******************************************************************************** Many shrubs fruit or seed (snowberry, baldhip rose, ocean spray). Most of the exceptions are in the alpine garden where penstemon, several species of alpine daisies and a resplendent skyrocket (scarlet gilia) and Richardson's penstemon are still aflame and mountain monardella is hanging on. There are the expected pearly everlasting, asters and yarrow as well as the second coming of siberian miner's lettuce and cooley's hedge nettle.

  • Where Have All Our Asters Gone? by William R
    Sego Lily Spring 2018 41(2) Spring 2018 Volume 41 Number 2 Where Have All Our Asters Gone? by William R. Gray, Submitted to Sego Lily April 2018 ABSTRACT: the genus Aster traditionally contained numerous species from both North America and Eurasia. Based on morphological evidence and DNA sequencing in the 1990s it became clear that the North American species evolved separately, and would need to be assigned to other genera. This paper outlines the evidence, and the disposition of species as carried out in the Flora of North America in 2006. Whatever happened to Aster??? It used to be easy leading wildflower walks for UNPS. Yes, truly, all 21 Asters described by Cronquist in People would ask how to distinguish Asters from Intermountain Flora (Cronquist, 1994) have been Daisies – and I would tell them to look behind the reassigned to other genera by Flora of North America flower and check out the little greenish things (2006). According to FNA there is only a single true surrounding the petals (Fig. 1). If they were all about native Aster in the whole of North America, down from the same length, and skinny, it was probably a daisy or well over a hundred before the dis-Aster. The name is fleabane (Erigeron). If they varied in length, were wider now used almost exclusively for Eurasian plants and overlapped, it was probably an aster (Aster). because Linnaeus chose a well-known European plant For many people that was all they wanted to know and and named it Aster amellus as typical of the genus.

    APPENDIX N BIOLOGICAL DATABASE QUERIES AND LIST OF SPECIES OBSERVED NATURAL RESOURCES CONSERVATION SERVICE REPORT United States A product of the National Custom Soil Resource Department of Cooperative Soil Survey, Agriculture a joint effort of the United Report for States Department of Agriculture and other Shasta-Trinity National Federal agencies, State Natural agencies including the Forest Area, Parts of Resources Agricultural Experiment Conservation Stations, and local Humboldt, Siskiyou, Shasta, Service participants Tehama, and Trinity Counties, California; and Siskiyou County, California, Central Part September 6, 2016 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases.

    Eurybia merita (A. Nelson) G.L. Nesom synonym: Aster sibiricus L. var. meritus (A. Nelson) Raup Arctic aster Asteraceae - aster family status: State Sensitive, USFS sensitive rank: G5 / S1S2 General Description: Rhizomatous perennial commonly 10 cm tall or less, but robust forms can be up to 50 cm tall. Plants glandless. Stems decumbent to ascending; stem and lower leaf surfaces sparsely to copiously short-haired. Leaves alternate, firm, sessile or the lower leaves subpetiolate, 2.5-8 cm x 4-25 mm, the very lowermost usually reduced; margins with a few small teeth or smooth.floral characteristics Radiate heads solitary to few, rarely up to 20 in a compact inflorescence. Involucre 6-9 mm high. Involucral bracts overlapping in several series, loose and sometimes squarrose, papery in texture and not green below, evidently to obscurely green-tipped above, and strongly purple-margined or suffused with purple. Rays usually 12-23, purple, 8-12 mm long. Illustration by John H. Rumely, Flowers July to mid-September. ©1955 University of Washington Press Fruits: Achenes with several nerves; pappus with some shorter and more slender bristles of various lengths intermixed. Identification Tips: Smaller forms of Eurybia radulina* could be confused with Eurybia merita, but they are unlikely to co-occur in the same habitat. E. radulina is a larger, erect plant, 20-70 cm tall, with conspicuously toothed leaves and many flower heads with white (sometimes purplish) rays. Range: Circumboreal. In N.A. extending southward from AK, B.C., and Alberta to CA, UT, WY, and SD. © Richard Ramsden Habitat/Ecology: Open rocky places, rock crevices, alpine lithosols, and unstable talus slopes, mostly at high elevations in the mountains, from 700 to 2300 m (2400-7400 ft).
