  • The Giant Palouse Earthworm (Driloleirus Americanus)
    PETITION TO LIST The Giant Palouse Earthworm (Driloleirus americanus) AS A THREATENED OR ENDANGERED SPECIES UNDER THE ENDANGERED SPECIES ACT June 30, 2009 Friends of the Clearwater Center for Biological Diversity Palouse Audubon Palouse Prairie Foundation Palouse Group of the Sierra Club 1 June 30, 2009 Ken Salazar, Secretary of the Interior Robyn Thorson, Regional Director U.S. Department of the Interior U.S. Fish & Wildlife Service 1849 C Street N.W. Pacific Region Washington, DC 20240 911 NE 11th Ave Portland, Oregon Dear Secretary Salazar, Friends of the Clearwater, Center for Biological Diversity, Palouse Prairie Foundation, Palouse Audubon, Palouse Group of the Sierra Club and Steve Paulson formally petition to list the Giant Palouse Earthworm (Driloleirus americanus) as a threatened or endangered species pursuant to the Endangered Species Act (”ESA”), 16 U.S.C. §1531 et seq. This petition is filed under 5 U.S.C. 553(e) and 50 CFR 424.14 (1990), which grant interested parties the right to petition for issuance of a rule from the Secretary of Interior. Petitioners also request that critical habitat be designated for the Giant Palouse Earthworm concurrent with the listing, pursuant to 50 CFR 424.12, and pursuant to the Administrative Procedures Act (5 U.S.C. 553). The Giant Palouse Earthworm (D. americanus) is found only in the Columbia River Drainages of eastern Washington and Northern Idaho. Only four positive collections of this species have been made within the last 110 years, despite the fact that the earthworm was historically considered “very abundant” (Smith 1897). The four collections include one between Moscow, Idaho and Pullman, Washington, one near Moscow Mountain, Idaho, one at a prairie remnant called Smoot Hill and a fourth specimen near Ellensberg, Washington (Fender and McKey- Fender, 1990, James 2000, Sánchez de León and Johnson-Maynard, 2008).

  • Aquatic Snails of the Snake and Green River Basins of Wyoming
    Aquatic snails of the Snake and Green River Basins of Wyoming Lusha Tronstad Invertebrate Zoologist Wyoming Natural Diversity Database University of Wyoming 307-766-3115 [email protected] Mark Andersen Information Systems and Services Coordinator Wyoming Natural Diversity Database University of Wyoming 307-766-3036 [email protected] Suggested citation: Tronstad, L.M. and M. D. Andersen. 2018. Aquatic snails of the Snake and Green River Basins of Wyoming. Report prepared by the Wyoming Natural Diversity Database for the Wyoming Fish and Wildlife Department. 1 Abstract Freshwater snails are a diverse group of mollusks that live in a variety of aquatic ecosystems. Many snail species are of conservation concern around the globe. About 37-39 species of aquatic snails likely live in Wyoming. The current study surveyed the Snake and Green River basins in Wyoming and identified 22 species and possibly discovered a new operculate snail. We surveyed streams, wetlands, lakes and springs throughout the basins at randomly selected locations. We measured habitat characteristics and basic water quality at each site. Snails were usually most abundant in ecosystems with higher standing stocks of algae, on solid substrate (e.g., wood or aquatic vegetation) and in habitats with slower water velocity (e.g., backwater and margins of streams). We created an aquatic snail key for identifying species in Wyoming. The key is a work in progress that will be continually updated to reflect changes in taxonomy and new knowledge. We hope the snail key will be used throughout the state to unify snail identification and create better data on Wyoming snails.

  • Oregon Giant Earthworm Scientific Name: Driloleirus Macelfreshi
    SPECIES FACT SHEET Common Name : Oregon Giant Earthworm Scientific Name : Driloleirus macelfreshi (Smith 1937) (formerly Megascolides macelfreshi ) Phylum: Annelida Class: Oligochaeta Order: Haplotaxida Family: Megascolecidae Conservation Status Global Status (1989): G1 – critically imperiled National Status (2006): N1 – critically imperiled State Status (Oregon): S1 – critically imperiled IUCN Red List Category: VU - Vulnerable BLM Status: Bureau Sensitive Species (NatureServe 2009) Technical Description : Adult: The Oregon giant earthworm is one of the largest North American earthworms (Wells et al. 1983). It is distinguished by its characteristic large size (up to 1.32 m in length and between .5 and 1 cm in diameter), pale whitish color, and distinctive, floral (lily-like) odor (Fender 2009, pers. comm. ). The clitellum of this species (a swelling of the body towards the head of the worm where the gonads are located) extends from segments 13 to about 22, and there are numerous nephridia (networks of tubules that have an excretory function) on each body segment (Wells et al. 1983). Since immature specimens of this species are not as large, and since there are other large, white, fragrant earthworms in the Willamette Valley which could be mistaken for this taxon, specimen collection and expert identification based on internal anatomy is essential for this species. Fresh (refridgerated) specimens are best for identification (Fender 2009, pers. comm. ). William Fender is the foremost authority on the Oregon giant earthworm, and should be consulted regarding any collected or reported specimens. The use of genetic work for identification of this species is a future possibility (Rosenberg 2009, pers. comm ). There are currently no keys to megascolecid worms in this region (Applegarth 1995), although a complete, technical description can be found in Smith (1937).

FORSMAN, USDA Forest Service, Pacific Northwest Research Station, Forestry Sciences Laboratory, Corvallis, OR 97331, USA ABSTRACT The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted owls has emerged in the form of an invasive competitor: the congeneric barred owl (S. varia). As barred owls have rapidly expanded their populations into the entire range of the northern spotted owl, mounting evidence indicates that they are displacing, hybridizing with, and even killing spotted owls.

  • Habitat Assessment of the Pacific Sideband (Monadenia Fidelis) in the Lower Fraser Valley British Columbia
    Pacific Sideband 1 Habitat Assessment of the Pacific Sideband (Monadenia fidelis ) In the Lower Fraser Valley British Columbia December 20, 2007 Darren Brown, BIT Ryan Durand, R.P.Bio. Fraser Valley Conservancy Society Abbotsford, BC Pacific Sideband 2 Executive Summary The Pacific sideband ( Monadenia fidelis ) is the largest land snail known to occur in British Columbia. Although blue-listed in British Columbia for apparent scarcity and threats to its habitat, the snail is widespread throughout the western United States. This report attempts to define the habitat requirement of the Pacific sideband in the lower Fraser Valley; specifically the Abbotsford area and to a lesser degree adjacent municipalities. Data was collected in conjunction with a variety of mapping projects from January 2005 to August 2007. Additional data continues to be collected and may be used to refine this report in the future. Data from 159 sample plots were analyzed to determine a variety of ecological and physical site features of preferred snail habitat. Analysis included physical conditions such as slope, elevation, and substrate, as well as ecological descriptions of dominant vegetation and associations of trees, shrubs, and herbs. In general the results of this study indicate that Pacific sideband is most commonly associated with relatively undisturbed deciduous and mixed forested areas. However, its habitat requirements appeared to be highly variable and we continue to find it in unexpected locations. Pacific Sideband 3 Acknowledgements There are several people who helped with this study. Sincere thanks to Ryan Durand for providing me this incredible opportunity to work with him. Also special thanks to Michelle Scott and Natashia Cox of Taara Environmental who assisted with data collection throughout the project.
