Morro Shoulderband Snail Report, Padre MEMORANDUM To: EMC Planning Group Project No: 1902-1172 Attn: Teri Wissler From: Alyssa Berry – Senior Biologist (Padre Associates, Inc.) Kenny Wimer – Staff Biologist (Padre Associates, Inc.) Date: February 3, 2021 Subject: Protocol Survey Results for Morro Shoulderband Snail for the Battery Energy Storage System Project, City of Morro Bay, California This memorandum has been prepared by Padre Associates, Inc. (Padre) to document the progress and interim findings of United States Fish and Wildlife (USFWS) protocol surveys for the Morro shoulderband snail (MSS) (Helminthoglypta walkeriana) at the Battery Energy Storage System (BESS) Project Site, located within the Vistra Power Plant Property (Property) in the City of Morro Bay, California (Project Site). To date, three of the five required surveys have been completed with negative results for MSS. Upon completion of the remaining two surveys, a summary report of results will be prepared and submitted. Surveys were conducted on December 14 and 29, 2020 and January 29, 2021, by Ecological Assets Management, LLC (EAM) USFWS-permitted Biologists, Dwayne Oberhoff and Bob Sloan, with accompaniment by Padre Biologists, Michaela Hoffman and Kenny Wimer on an alternating basis. The surveys are being conducted to document the presence or absence of MSS at the Project Site in support of the BESS permitting application process. Per USFWS protocol, a total of five MSS surveys are required, including a habitat assessment, that are spaced at least one week apart and within 24 hours of a rain event. Survey methodology included traveling by foot throughout the Property while searching for any potential MSS. Living snails, as well as remnant shells, were inspected for MSS identification characteristics such as shell dimensions, spire profile, markings, and groove pattern. A hand magnifying lens was used on some older/sun-bleached shells, as needed. All potentially suitable habitat areas were surveyed, including native/non-native vegetation and around/beneath structures and debris. Special attention was paid to the organic layer (duff) beneath shrub species known to be favored by MSS, including silver bush lupine (Lupinus chamissonis) and coyote brush (Baccharis pilularis). The duff layer was turned over by hand and inspected for snails. Due to the high amount of water runoff during the previous days’ rain, areas of pooled water where remnant shells may have collected were inspected as well. No living or dead MSS were observed during any of the surveys. Other species observed included Big Sur shoulderband snail (Helminthoglypta umbilicata) and brown garden snail (Helix 369 Pacific Street ▲ San Luis Obispo, CA 93401 ▲ (805) 786-2650 ▲ Fax (805) 786-2651 www.padreinc.com Battery Energy Storage System Project Morro Shoulderband Snail Memo February 3, 2021 (1902-1172) aspera). In general, remnant shells and fragments far-outnumbered living snails; however, snail movement and mating was observed, likely related to the previous days’ rain, and indicating that it was an optimal time to survey for MSS. Per USFWS protocol, two more surveys will be conducted during the 2020/2021 rainy season pending additional rain events that are spaced at least one week apart. If you have any questions or comments regarding the contents of this memorandum, please contact Alyssa Berry at (805) 722-5458 or by email at [email protected], or Kenny Wimer at (805) 215-8089, or by email at [email protected].

(Padre) on behalf of Dynegy Morro Bay, LLC (Dynegy) at the Morro Bay Power Plant (APN 066-331-040) located in Morro Bay, San Luis Obispo County, California. This report presents the methods and results of five protocol-level Morro shoulderband snail (MSS) surveys and habitat assessment conducted from November 16, 2015, to January 19, 2016, on an approximate 9.45 acre area (Survey Area) located in the western portion of the 107 acre Morro Bay Power Plant (MBPP) facility. This report provides a description of existing conditions within the Survey Area and adjacent areas, and, in combination with the protocol surveys results, determines whether Morro shoulderband snail and/or suitable habitat for Morro shoulderband snail is present. In summary, the five protocol surveys conducted within the 9.45 acre Survey Area observed no live or empty MSS shells. Restricted and small areas of suitable habitat (e.g. coastal dune scrub, ice plant and sandy soils) were observed within the Survey Area. During the protocol surveys numerous empty shells from both Big Sur shoulderband snail (Helminthoglypta umbilicata) and brown garden snail (Helix aspera) were observed. Numerous previous surveys and monitoring efforts conducted by other biologists from 1999 to 2010 within the Survey Area also found no MSS. Based on the results of the five protocol surveys and habitat assessment presented in this report, and the previous MSS survey and monitoring efforts, “take” of MSS will not occur from the proposed project within the Survey Area. Thus, Padre, on behalf of Dynegy, is requesting a no-take concurrence determination for the proposed project.

(Padre) on behalf of Dynegy Morro Bay, LLC (Dynegy) at the Morro Bay Power Plant (APN 066-331-040) located in Morro Bay, San Luis Obispo County, California. This report presents the methods and results of five protocol-level Morro shoulderband snail (MSS) surveys and habitat assessment conducted from November 16, 2015, to January 19, 2016, on an approximate 9.45 acre area (Survey Area) located in the western portion of the 107 acre Morro Bay Power Plant (MBPP) facility. This report provides a description of existing conditions within the Survey Area and adjacent areas, and, in combination with the protocol surveys results, determines whether Morro shoulderband snail and/or suitable habitat for Morro shoulderband snail is present. In summary, the five protocol surveys conducted within the Survey Area observed no live or empty MSS shells. Restricted and small areas of suitable habitat (e.g. coastal dune scrub, ice plant and sandy soils) were observed within the Survey Area.

Based on the results of the five protocol surveys and habitat assessment presented in this report, and the previous MSS survey and monitoring efforts, “take” of MSS will not occur from the proposed project within the Survey Area. Protocol Survey and Habitat Assessment Methods The 2003 United States Fish and Wildlife Service (USFWS) Protocol Survey Guidelines for MSS require that protocol surveys be performed during or immediately following a rain event (i.e. protocol conditions) to establish the presence or absence of MSS at a location. Protocol surveys must include a general habitat assessment that identifies key habitat features within and adjacent to the Survey Area. This report is based on the results of five separate site visits to the approximate 9.45 acre Survey Area of the 107 acre subject parcel to conduct five protocol surveys and a concurrent MSS habitat assessment. The surveys were conducted on November 16, December 11, December 22, 2015; and, January 7, and January 19, 2016. The protocol surveys on November 16 and December 11 and 22, 2015, were conducted by permitted biologists Dwayne Oberhoff and Bob Sloan. The protocol surveys on January 7 and 19, 2016, were conducted by permitted biologist Dwayne Oberhoff. Dwayne Oberhoff is permitted to conduct MSS protocol surveys under federal recovery permit TE-180579-1. Bob Sloan is permitted to conduct MSS protocol surveys under federal recovery permit TE-43937B-0.

  • Helminthoglypta Walkeriana COMMON NAME: Morro Shoulderband Snail CLASS, FAMILY: Gastropoda, Helminthoglyptidae
    SCIENTIFIC NAME: Helminthoglypta walkeriana COMMON NAME: Morro shoulderband snail CLASS, FAMILY: Gastropoda, Helminthoglyptidae ORIGINAL DESCRIPTION: Hemphill, H. 1911. Descriptions of some varieties of shells, with short notes on the geographical range and means of distribution of land snails. Transactions of the San Diego Society of Natural History 1(3):102, pl. 2 (two views of shells). (Described as Helix walkeriana, with morroensis described as a variety.) TYPE MATERIAL: Roth and Sadeghian (2003) list the syntypes as follows: Academy of Natural Sciences, Philadelphia #112424 (4 specimens), California Academy of Sciences #058838 (6), #065523 (2), #065524 (3), Santa Barbara Museum of Natural History #33958 (22), University of Colorado, Boulder #20178 (4), and United States National Museum of Natural History (Smithsonian Institution) #174679-174682 (8). RANKING/STATUS: Federally Endangered (1994), G1S1 (NatureServe – CNDDB), CR/A1ce, B1+2bc (IUCN). GENERAL DESCRIPTION: Moderately large helminthoglyptid snails with globose, helicoid shells and brown bodies. DIAGNOSTIC CHARACTERS: Only three helminthoglyptid species occur in coastal San Luis Obispo County; until recently H. morroensis was considered a subspecies of H. walkeriana (Walgren 2003). The third species, H. umbilicata, has distinctive malleated shell sculpture (Roth and Tupen 2004). Detailed morphometric analysis of shells (Roth and Tupen 2004) revealed that H. walkeriana and H. morroensis are separate species. Shells of H. walkeriana are more globose and tightly coiled, with more whorls and less papillation than those of H. morroensis. The skin color of morroensis is blackish in life, whereas in walkeriana it is medium brown, and the mantle pigmentation is more extensive in morroensis. Penial morphology also differs, with the penis of walkeriana being slender and hourglass-shaped, with simple, smooth pilasters.

  • Population Viability Analysis for Pacific Coast Western Snowy Plovers
    APPENDIX D POPULATION VIABILITY ANALYSIS FOR PACIFIC COAST WESTERN SNOWY PLOVERS Nadav Nur Gary W. Page Lynne E. Stenzel Point Reyes Bird Observatory 4990 Shoreline Highway Stinson Beach, CA 94970 March 1999 e-mail: [email protected] [email protected] [email protected] Acknowledgments We thank Mark Stern, Carole Hallett, and Abby Powell for providing and summarizing data used for parameter estimation in the population viability analysis. We thank all the members of the Western Snowy Plover Recovery Team Technical Subcommittee, as well as numerous outside reviewers, for helpful comments and discussion on earlier drafts of the population viability analysis. Introduction In 1993 the Pacific coast population of the western snowy plover (Charadrius alexandrinus nivosus) (western snowy plover) was designated as threatened by the U.S. Fish and Wildlife Service under the Endangered Species Act of 1973, as amended (16 USC 1531 et seq.). To aid D-1 the Western Snowy Plover Recovery Team in developing recovery criteria, the authors developed this population viability analysis for the Pacific coast population of the western snowy plovers. Population viability analysis is used increasingly as a tool for developing conservation, management or restoration strategies for threatened, endangered, or potentially threatened species. The method is reviewed by Boyce (1992), Burgman et al. (1993), Beissinger and Westphal (1998) and Nur and Sydeman (1999). Examples of its use include Haig et al. (1993), Maguire et al. (1995), Akçakaya et al. (1995), and Bustamante (1996). In particular, population viability analyses have been developed for the congener piping plover Charadrius melodus (Great Plains population: Ryan et al. 1993; Atlantic coast population: Melvin and Gibbs 1996).

    www.doi.org/10.51492/cfwj.cesasi.6 California Fish and Wildlife Special CESA Issue:107-145; 2021 FULL RESEARCH ARTICLE Phylogenetic relationships among subclades within the Trinity bristle snail species complex, riverine barriers, and re-classification ROBERT M. SULLIVAN* California Department of Fish and Wildlife, Region 1, Wildlife/Lands Program, P.O. Box 1185 Weaverville, California 96093 *Corresponding Author: [email protected] The Trinity bristle snail (Monadenia setosa) is listed as a threatened species under the California Endangered Species Act (CESA). In northern California, populations of this endemic terrestrial gastropod occur in rare, isolated, and highly fragmented locations within the greater Trinity Basin. Since 1952 when it was originally described, the taxonomic status of the Trinity bristle snail has been questioned based on unpublished information limited in geographic scope and sample size, which resulted in the taxon being reduced from species status (M. setosa) to subspecific status (M. i. setosa) within the Redwood sideband (M. infumata) species complex. Primary objectives of the present study were to: 1) use DNA extraction and PCR sequencing to gain insight into patterns of genetic variation and phylogenetic relationships among a larger sample of en- demic populations of the Trinity bristle snail; 2) re-evaluate the systematic and taxonomic status of the species using outgroup analysis and references samples from sympatric ecologically co-occurring taxa within the genus Monadenia; and 3) evaluate the potential biogeographic effects ofmajor riverine systems on genetic differentiation among relic and disjunct populations within the Trinity Basin. Results of the DNA sequence analysis using several different tree re- construction methods revealed that subspecies of the Redwood sideband (M.

ACTION: Proposed rule. SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to reclassify the Morro shoulderband snail (Helminthoglypta walkeriana) from an endangered to a threatened species under the Endangered Species Act of 1973, as amended (Act), and we propose a special rule under section 4(d) of the Act. This proposed reclassification is based on our evaluation of the best available scientific and commercial information, which indicates that the species' status has improved such that it is not currently in danger of extinction throughout all or a significant portion of its range, but that it is still likely to become so in the foreseeable future. We also propose to update the Federal List of Endangered and Threatened Wildlife to reflect the latest scientifically accepted taxonomy and nomenclature for the species as Helminthoglypta walkeriana, Morro shoulderband snail. We seek information, data, and comments from the public on this proposal. We also announce the availability of an assessment of the status of the Chorro shoulderband 1 snail (Helminthoglypta morroensis) in which we conclude that the species does not meet the definition of a threatened species or an endangered species.

    Eucalyptus spp. Alter Land Snail Species Assemblage Figure 4. Morro shoulderband snail, Helminthoglypta walkeriana Michael Walgren, Lisa Andreano (federally listed) Environmental Scientists 1 Lower State Park Road, Morro Bay, Ca, 93442 Results Phone: 805-610-1931 E-mail: [email protected] Vegetation data collected outside the eucalyptus documented coastal scrub and dune scrub communities with varying levels of invasive perennial veldt grass (Ehrharta calycina), whereas vegetation within the eucalyptus forest was sparse or nonexistent. We found 38 MSS shells in non-eucalyptus habitat and 1 MSS shell within the canopy edge of E. cephalocarpa (Figure 2).
