  • "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.

    ALPLAINS 2013 SEED CATALOG P.O. BOX 489, KIOWA, CO 80117-0489, U.S.A. Three ways to contact us: FAX: (303) 621-2864 (24 HRS.) email: [email protected] website: www.alplains.com Dear Growing Friends: Welcome to our 23rd annual seed catalog! The summer of 2012 was long, hot and brutal, with drought afflicting most of the U.S. Most of my botanical explorations were restricted to Idaho, Wash- ington, Oregon and northern California but even there moisture was below average. In a year like this, seeps, swales, springs, vestigial snowbanks and localized rainstorms became much more important in my search for seeding plants. On the Snake River Plains of southern Idaho and the scab- lands of eastern Washington, early bloomers such as Viola beckwithii, V. trinervata, Ranunculus glaberrimus, Ranunculus andersonii, Fritillaria pudica and Primula cusickiana put on quite a show in mid-April but many populations could not set seed. In northern Idaho, Erythronium idahoense flowered extensively, whole meadows were covered with thousands of the creamy, pendant blossoms. One of my most satisfying finds in the Hells Canyon area had to be Sedum valens. The tiny glaucous rosettes, surround- ed by a ring of red leaves, are a succulent connoisseur’s dream. Higher up, the brilliant blue spikes of Synthyris missurica punctuated the canyon walls. In southern Oregon, the brilliant red spikes of Pedicularis densiflora lit up the Siskiyou forest floor. Further north in Oregon, large populations of Erythronium elegans, Erythronium oregonum ssp. leucandrum, Erythro- nium revolutum, trilliums and sedums provided wonderful picture-taking opportunities. Eriogonum species did well despite the drought, many of them true xerics.

  • Representativeness Assessment of Research Natural Areas on National Forest System Lands in Idaho
    USDA United States Department of Representativeness Assessment of Agriculture Forest Service Research Natural Areas on Rocky Mountain Research Station National Forest System Lands General Technical Report RMRS-GTR-45 in Idaho March 2000 Steven K. Rust Abstract Rust, Steven K. 2000. Representativeness assessment of research natural areas on National Forest System lands in Idaho. Gen. Tech. Rep. RMRS-GTR-45. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 129 p. A representativeness assessment of National Forest System (N FS) Research Natural Areas in ldaho summarizes information on the status of the natural area network and priorities for identification of new Research Natural Areas. Natural distribution and abundance of plant associations is compared to the representation of plant associations within natural areas. Natural distribution and abundance is estimated using modeled potential natural vegetation, published classification and inventory data, and Heritage plant community element occur- rence data. Minimum criteria are applied to select only viable, high quality plant association occurrences. In assigning natural area selection priorities, decision rules are applied to encompass consideration of the adequacy and viability of representation. Selected for analysis were 1,024 plant association occurrences within 21 4 natural areas (including 115 NFS Research Natural Areas). Of the 1,566 combinations of association within ecological sections, 28 percent require additional data for further analysis; 8, 40, and 12 percent, respectively, are ranked from high to low conservation priority; 13 percent are fully represented. Patterns in natural area needs vary between ecological section. The result provides an operational prioritization of Research Natural Area needs at landscape and subregional scales.

  • Palouse Forbs for Landscaping
    More Palouse Forbs for Landscaping. by David M. Skinner, Paul Warnick, Bill French, and Mary Fauci November, 2005 The following is an additional list of native forbs which may be found in the Palouse region. These forbs may be less suitable for the landscape because of growth habit, aggressiveness, difficulty in propagating and growing, rarity, or it simply may be that we haven’t yet tried to do anything with them. For a list of Palouse forbs which may be more suitable for landscaping and about which we have more information to share, please see “Characteristics and Uses of Native Palouse Forbs in Landscaping.” Nomenclature used in this document also follows Hitchcock, C. Leo, and Arthur Cronquist. 1973. Flora of the Pacific Northwest. Univ. of Washington Press. Seattle, WA. In order to facilitate searching for a particular species, we have included some common names and alternate scientific names, but this is by no means intended to be a comprehensive source of common names or synonyms. Detailed information on propagation of many native species can be found at <http://nativeplants.for.uidaho.edu/network/search.asp?SearchType=Continental> Agastache urticifolia is probably too large a plant for a small garden. Requires a moist site. Easy to grow from seed. Plants have a minty smell and a very interesting flower. Common names include nettle-leafed giant hyssop, horsemint. Agoseris grandiflora is not a particularly attractive plant, it looks rather like a weed. Short-lived and attracts rodents, which eat the taproot and kill the plants. Easy to grow from seed, which is wind-borne and goes everywhere.

    Rare Plant Survey of San Juan Public Lands, Colorado 2005 Prepared by Colorado Natural Heritage Program 254 General Services Building Colorado State University Fort Collins CO 80523 Rare Plant Survey of San Juan Public Lands, Colorado 2005 Prepared by Peggy Lyon and Julia Hanson Colorado Natural Heritage Program 254 General Services Building Colorado State University Fort Collins CO 80523 December 2005 Cover: Imperiled (G1 and G2) plants of the San Juan Public Lands, top left to bottom right: Lesquerella pruinosa, Draba graminea, Cryptantha gypsophila, Machaeranthera coloradoensis, Astragalus naturitensis, Physaria pulvinata, Ipomopsis polyantha, Townsendia glabella, Townsendia rothrockii. Executive Summary This survey was a continuation of several years of rare plant survey on San Juan Public Lands. Funding for the project was provided by San Juan National Forest and the San Juan Resource Area of the Bureau of Land Management. Previous rare plant surveys on San Juan Public Lands by CNHP were conducted in conjunction with county wide surveys of La Plata, Archuleta, San Juan and San Miguel counties, with partial funding from Great Outdoors Colorado (GOCO); and in 2004, public lands only in Dolores and Montezuma counties, funded entirely by the San Juan Public Lands. Funding for 2005 was again provided by San Juan Public Lands. The primary emphases for field work in 2005 were: 1. revisit and update information on rare plant occurrences of agency sensitive species in the Colorado Natural Heritage Program (CNHP) database that were last observed prior to 2000, in order to have the most current information available for informing the revision of the Resource Management Plan for the San Juan Public Lands (BLM and San Juan National Forest); 2.
