This memorandum and enclosed Biological Opinion (BO) respond to your request for formal consultation with the U.S. Fish and Wildlife Service (Service) pursuant to section 7 of the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.), as amended (Act). At issue in this consultation are the effects resulting from adoption by the Bureau of Land Management of the West Eugene Wetlands Resource Management Plan (RMP) and the associated West Eugene Wetlands Plant and Invertebrate Monitoring Plan as updated December 18, 2013, on the endangered Bradshaw's lomatium (Lomatium bradshawii), threatened Kincaid's lupine (Lupinus oreganus), endangered Willamette daisy (Erigeron decumbens var. decumbens), endangered Fender's blue butterfly (Icaricia icarioides fenderi), endangered Taylor's checkerspot butterfly(Euphydryas editha taylori) and the threatened streaked homed lark (Eremophila alpestris strigata), and the critical habitats ofthe Kincaid's lupine, Willamette daisy and Fender' s blue butterfly. Your request for formal consultation was received in our office on April 7, 2014. Our conclusion for formal consultation is that implementation of the activities as described within the Biological Assessment would not jeopardize the continued existence of any listed species described within the BO nor would it adversely modify their critical habitat. If you have any questions regarding this BO, please contact Paul Bridges at 541-957-3404, or Brendan White at (503) 231-6179.

  • Botany Biological Evaluation
    APPENDIX I Botany Biological Evaluation Biological Evaluation for Threatened, Endangered and Sensitive Plants and Fungi Page 1 of 35 for the Upper Truckee River Sunset Stables Restoration Project November 2009 UNITED STATES DEPARTMENT OF AGRICULTURE – FOREST SERVICE LAKE TAHOE BASIN MANAGEMENT UNIT Upper Truckee River Sunset Stables Restoration Project El Dorado County, CA Biological Evaluation for Threatened, Endangered and Sensitive Plants and Fungi PREPARED BY: ENTRIX, Inc. DATE: November 2009 APPROVED BY: DATE: _____________ Name, Forest Botanist, Lake Tahoe Basin Management Unit SUMMARY OF EFFECTS DETERMINATION AND MANAGEMENT RECOMMENDATIONS AND/OR REQUIREMENTS One population of a special-status bryophyte, three-ranked hump-moss (Meesia triquetra), was observed in the survey area during surveys on June 30, 2008 and August 28, 2008. The proposed action will not affect the moss because the population is located outside the project area where no action is planned. The following species of invasive or noxious weeds were identified during surveys of the Project area: cheatgrass (Bromus tectorum); bullthistle (Cirsium vulgare); Klamathweed (Hypericum perforatum); oxe-eye daisy (Leucanthemum vulgare); and common mullein (Verbascum Thapsus). The threat posed by these weed populations would not increase if the proposed action is implemented. An inventory and assessment of invasive and noxious weeds in the survey area is presented in the Noxious Weed Risk Assessment for the Upper Truckee River Sunset Stables Restoration Project (ENTRIX 2009). Based on the description of the proposed action and the evaluation contained herein, we have determined the following: There would be no significant effect to plant species listed as threatened, endangered, proposed for listing, or candidates under the Endangered Species Act of 1973, as amended (ESA), administered by the U.S.

  • Redacted for Privacy W
    AN ABSTRACT OF THE THESIS OF Aaron D. Drew for the degree of Master of Science in Wildlife Science presented on December 19. 2000. Title: Effects of Livestock Grazing and Small Mammal Populations on Endangered Bradshaw's Desert Parsley (Lomatium bradshawii) at Oak Creek. Willamette Valley. Oregon. Abstract approved: Redacted for privacy W. Daniel I evaluated the response of the federally listed endangered plant species Bradshaw's desert parsley (Lomatium bradshawii) to livestock grazing and small mammal depredation at Oak Creek, Linn County, Oregon, 1997-1998. I established six study blocks (three each in wooded and herbaceous pastures) with plots in each block randomly assigned to one of four intensities of livestock grazing based on biomass remaining after grazing (no grazing [1,746 kg/ha], high biomass [969 kg/ha], moderate biomass [670 kg/ha], and light biomass [318 kg/ha]). Small mammals were live-trapped in each of the study blocks pre and post application of the livestock grazing treatments. I mapped and measured 2,807 Bradshaw's desert parsley plants (n1,366 in the wooded and n = 1,441 in the herbaceous pastures) over the two year period to determine changes in schizocarp production, morphological structure (conical surface area and height), population composition (plant stage), survival, emergence of new plants, and effects of small mammal herbivory pre and post application of livestock grazing. Grazing reductions in standing crop biomass appeared to have a positive effect on emergence of new Bradshaw's desert parsley plants, while having no detectible effect on total plant density or survival. Differences in total plant density, survival, schizocarp production, morphological structure, and population composition were related to pasture type.

Mills, Chair This dissertation combines two disparate subjects: bees and belonging. The first two chapters explore pesticide exposure for wild bees and honey bees visiting crop and non-crop plants in northern California agriculture. The final chapter utilizes surveys from a mentorship program as a case study to analyze sense of belonging among undergraduates. The first chapter of this dissertation explores pesticide exposure for wild bees and honey bees visiting sunflower crops.

  • Fern Ridge Research Natural Area
    FERN RIDGE RESEARCH NATURAL AREA Fern Ridge RNA 2014 Abstract Public land provides benefits including species conservation, ecological function, and scientific knowledge. Authorized by Congress in 1939, the Corps of Engineers’ Fern Ridge Project (Oregon, Wes Messinger, Corps of Engineers Willamette Valley Project Lane County) includes nearly 5500 acres of marsh, wet and upland prairie, and deciduous forest: a significant quantity of publicly held habitat on the heavily utilized Willamette Valley floor. Following Heritage Program surveys in the 1980s, the Corps designated 250 acres of wet prairie as the Fern Ridge Research Natural Area. These sites comprise the only Corps of Engineers RNA, and one of two on the floor of the Willamette Valley. Other land use designations on these parcels include the Oregon Department of Fish and Wildlife Fern Ridge Wildlife Area and Critical Habitat for Erigeron decumbens and Fender’s blue butterfly. The RNA supports 10 plant species of conservation concern including Lupinus oreganus, Sericocarpus rigidus, Horkelia congesta, the largest remnant population of Erigeron decumbens, and large numbers of Lomatium bradshawii. It is the type locality of The Fern Ridge Research Natural Area was dedicated in 1988 by the Amanita pruittii, described in 2014. It supports nesting territories of Western Meadowlarks and Grasshopper Sparrows. Corps management is intended to sustain ecological processes including fire Commander of the Portland District, U.S. Army Corps of Engineers. It Microtopography and sheet and to reduce the influence of eXotic species. Two dozen studies on the RNA include seminal work flow, Royal Amazon unit on prescribed fire and Lomatium bradshawii demography. Current studies address prairie fungi serves the natural area system as a high quality eXample of remnant communities, plant demographics, and eXotic grass control against a background of prescribed fire.

Federal law requires a non-federal landowner who wishes to conduct activities that may harm (“take”) threatened or endangered wildlife on their land to obtain an incidental take permit from the U.S. Fish and Wildlife Service. State law requires a non-federal public landowner who wishes to conduct activities that may harm threatened or endangered plants to obtain a permit from the Oregon Department of Agriculture.
