FE = Federally Endangered; FT = Federally Threatened; PT = Proposed for Federal listing; CH = Designated Critical Habitat GSNM Specialist Report Wildlife Biological Assessment 2 Wildlife Biological Assessment Introduction This Biological Assessment (BA) documents analysis of programmatic direction (long term goal and objective based management) rather than individual projects under the Giant Sequoia National Monument Management Plan Draft Environmental Impact Statement. A determination is made on potential effects to wildlife species listed as Threatened, Endangered, or Proposed for listing (Listed species) under the Endangered Species Act (ESA) by the U.S. Department of Interior, Fish and Wildlife Service (USFWS). USFWS species of concern, candidates for listing under the ESA and Forest Service Sensitive species are covered in a separate document (Biological Evaluation for the Giant Sequoia National Monument Management Plan Draft Environmental Impact Statement). This biological assessment (BA) was prepared in accordance with Forest Service Manual (FSM) direction 2672.42, and meets legal requirements under Section 7 of the Endangered Species Act of 1973, as amended, and implements regulations [19 U.S.C. 1536 (c), 50 CFR 402.12 (f) and 402.14 (c)]. The BA provides a process through which federally listed species under the Endangered Species Act receive full consideration in the decision making process. Table 1.

  • Conceptual Design Documentation
    Appendix A: Conceptual Design Documentation APPENDIX A Conceptual Design Documentation June 2019 A-1 APPENDIX A: CONCEPTUAL DESIGN DOCUMENTATION The environmental analyses in the NEPA and CEQA documents for the proposed improvements at Oceano County Airport (the Airport) are based on conceptual designs prepared to provide a realistic basis for assessing their environmental consequences. 1. Widen runway from 50 to 60 feet 2. Widen Taxiways A, A-1, A-2, A-3, and A-4 from 20 to 25 feet 3. Relocate segmented circle and wind cone 4. Installation of taxiway edge lighting 5. Installation of hold position signage 6. Installation of a new electrical vault and connections 7. Installation of a pollution control facility (wash rack) CIVIL ENGINEERING CALCULATIONS The purpose of this conceptual design effort is to identify the amount of impervious surface, grading (cut and fill) and drainage implications of the projects identified above. The conceptual design calculations detailed in the following figures indicate that Projects 1 and 2, widening the runways and taxiways would increase the total amount of impervious surface on the Airport by 32,016 square feet, or 0.73 acres; a 6.6 percent increase in the Airport’s impervious surface area. Drainage patterns would remain the same as both the runway and taxiways would continue to sheet flow from their centerlines to the edge of pavement and then into open, grassed areas. The existing drainage system is able to accommodate the modest increase in stormwater runoff that would occur, particularly as soil conditions on the Airport are conducive to infiltration. Figure A-1 shows the locations of the seven projects incorporated in the Proposed Action.

Orsen Ul December 1977 MIKES UMARr " T h e s i s m 9 7 @ 1978 DAVID ALAN ORSEN ALL RIGHTS RESERVED The thesis of David A. Orsen is approved: University of Nevada Reno D ec|inber 1977 XI ABSTRACT Crystal Peak, Coal Valley and Coaldale lignites were deposited in penecontemporaneous environments containing similar floral assemblages indicating a uniform climatic regime may have existed over west-central Nevada during late Barstovian-early Clarendoni&n time. Palynological evidence indicates a late Duchesnean to early Chadronian age for the lignites at Elko. At Tick Canyon no definitive age was ascertained. At all locations, excepting Tick Canyon, field and palynologic evidence indicates low energy, shallow, fresh-water environments existed during the deposition of the lignite sequences. Pollen grains indicated that woodland communities dominated the landscape while mixed forests existed locally. Aquatic and marsh-like vegetation inhabited, and was primarily responsible for the in situ organic deposits in the shallower regions of the lakes. At each location, particularly at Tick Canyon, transported organic material noticeably contributed to the deposits. Past production is recorded from Coal Valley and Coaldale, however no future development seems feasible. PLEASE NOTE: This dissertation contains color photographs which will not reproduce

  • BIOLOGICAL ASSESSMENT for the LUCAS Creek PROJECT KERN
    Biological Assessment- Lucas Creek Project BIOLOGICAL ASSESSMENT For the LUCAS Creek PROJECT KERN RIVER RANGER DISTRICT SEQUOIA NATIONAL FOREST Kern County, California PREPARED By:--J; �ATE: February 5, 2018 Nina Hemphi Forest Fish Biologist/Aquatic Ecologist and Watershed Manager This Biological Assessment analyzes the potential impacts associated with implementation of the Lucas Creek Project on federal endangered and threatened species as identified under the Endangered Species Act. The environmental analysis evaluates the preferred alternative. The Lucas Creek Project includes removal of dead and dying trees on 250 acres on Breckenridge Mountain. The project area is located in sections 23, 24, 25, & 26, township 28 south, range 31 east, Mount Diablo Base Meridian on the Kern River Ranger District of the Sequoia National Forest. The project surrounds the Breckenridge subdivision on Breckenridge Mountain approximately 25 miles southwest of the town of Lake Isabella in Kern County California. The intent of the Lucas Creek Project is to remove hazard trees along roads and properties adjoining the Breckenridge Subdivision. The project would also reduce fuels build-up to protect the community and the Lucas Creek upper and middle watershed from high-intensity fire. This will improve forest resilience and watershed health. This document is prepared in compliance with the requirements of FSM 2672.4 and 36 CFR 219.19. Biological Assessment- Lucas Creek Project I. INTRODUCTION The purpose of this Biological Assessment (BA) is to review the potential effects of Lucas Creek Project on species classified as federally endangered and threatened under the Endangered Species Act (ESA, 1973). Federally listed species are managed under the authority of the Endangered Species Act (ESA) and the National Forest Management Act (NFMA; PL 94- 588).

  • North American Species of Cerambycid Beetles in the Genus Neoclytus Share a Common Hydroxyhexanone-Hexanediol Pheromone Structural Motif
    FOREST ENTOMOLOGY North American Species of Cerambycid Beetles in the Genus Neoclytus Share a Common Hydroxyhexanone-Hexanediol Pheromone Structural Motif ANN M. RAY,1,2 JOCELYN G. MILLAR,3 JARDEL A. MOREIRA,3 J. STEVEN MCELFRESH,3 4,5 6 4 ROBERT F. MITCHELL, JAMES D. BARBOUR, AND LAWRENCE M. HANKS J. Econ. Entomol. 108(4): 1860–1868 (2015); DOI: 10.1093/jee/tov170 ABSTRACT Many species of cerambycid beetles in the subfamily Cerambycinae are known to use male-produced pheromones composed of one or a few components such as 3-hydroxyalkan-2-ones and the related 2,3-alkanediols. Here, we show that this pheromone structure is characteristic of the ceram- bycine genus Neoclytus Thomson, based on laboratory and field studies of 10 species and subspecies. Males of seven taxa produced pheromones composed of (R)-3-hydroxyhexan-2-one as a single compo- nent, and the synthetic pheromone attracted adults of both sexes in field bioassays, including the eastern North American taxa Neoclytus caprea (Say), Neoclytus mucronatus mucronatus (F.), and Neoclytus scu- tellaris (Olivier), and the western taxa Neoclytus conjunctus (LeConte), Neoclytus irroratus (LeConte), and Neoclytus modestus modestus Fall. Males of the eastern Neoclytus acuminatus acuminatus (F.) and the western Neoclytus tenuiscriptus Fall produced (2S,3S)-2,3-hexanediol as their dominant or sole pheromone component. Preliminary data also revealed that males of the western Neoclytus balteatus LeConte produced a blend of (R)-3-hydroxyhexan-2-one and (2S,3S)-2,3-hexanediol but also (2S,3S)- 2,3-octanediol as a minor component. The fact that the hydroxyketone-hexanediol structural motif is consistent among these North American species provides further evidence of the high degree of conservation of pheromone structures among species in the subfamily Cerambycinae.
