The focus of this effort was to update information on special-status plant and wildlife species (as defined by CEQA) and sensitive habitats within the City‘s planning jurisdiction, excluding the University of Santa Cruz and City lands outside of the City proper. To this end, EcoSystems West reviewed all available documents on these resources, consulted with local experts, and groundtruthed existing data where possible. In addition, as requested by the City of Santa Cruz, EcoSystems West conducted surveys of monarch butterfly habitat, seabird roosts and rookeries, and 172 vacant parcels that were at least 6,000 square feet (0.14 acres), to update information on these resources. This report is a summary of findings, including tables and narratives of special-status species, sensitive habitats, and a summary of the results of focused surveys. An accompanying geographic information system (GIS) database (geodatabase) provides spatial data created or updated as part of our work. EcoSystems West Consulting Group 7 January 2009 APPENDIX F-1 Biological Resources for the City of Santa Cruz General Plan Update METHODS Document Review and Consultation with Local Experts EcoSystems West met with City staff, reviewed all available data, technical studies, documents, EIRs, and the draft Citywide Habitat Conservation Plan (HCP) (unpublished) (Entrix 2004a,b; H.T. Harvey and Associates 2004). We reviewed the vegetation communities, sensitive species and habitat characterization of the City‘s existing GIS database, as well as more detailed information presented in the City‘s open space management plans and master plans. Up-to-date status information for species listed as ‗Threatened‘ or ‗Endangered‘ under the federal Endangered Species Act (ESA), and federal ‗Proposed‘ and ‗Candidate‘ species was obtained from U.S. Fish and Wildlife Service (USFWS). Up-to-date status information for State of California listed species was obtained from the California Department of Fish and Game (CDFG). For special-status plants we also reviewed the current California Native Plant Society's (CNPS) Inventory of Rare and Endangered Vascular Plants of California electronic database (CNPS 2007). Distribution and habitat information in standard regional floras (Munz and Keck 1973; Thomas 1960; and Hickman 1993) was reviewed. Status information was also obtained from Tibor (2001) for CNPS-listed species, including species on CNPS Lists 1 and 2 that are legally protected under the California Environmental Quality Act (CEQA). EcoSystems West reviewed current California Natural Diversity Database (CNDDB) records for occurrences of special-status species recorded in that database. In addition, we consulted with the following experts and organizations on local biological resources to identify additional occurrences of sensitive species: the local chapter of the California Native Plant Society, Dr. Richard Arnold and his Buggy Database regarding invertebrates, John Dayton and Tim Hyland on monarch butterflies, David Suddjian and Steve Gerow of the Santa Cruz Bird Club, as well as Brian Walton of the Santa Cruz Predatory Bird Research Group, in an effort to acquire updates on nesting birds, as well as preferred foraging and nesting locations of special-status birds. Based on this review, we identified all known sensitive habitats, special-status plants and animals documented within

  • Species Account CALLIPPE SILVERSPOT BUTTERFLY Speyeria Callippe Callippe
    U.S. Fish & Wildlife Service Sacramento Fish & Wildlife Office Species Account CALLIPPE SILVERSPOT BUTTERFLY Speyeria callippe callippe CLASSIFICATION: Endangered Federal Register 62:64306 ; December 5, 1997 http://ecos.fws.gov/docs/federal_register/fr3183.pdf CRITICAL HABITAT : None designated RECOVERY PLAN: Draft Recovery Plan For The Callippe Silverspot Butterfly (Under development) FIVE-YEAR REVIEW October 20, 2009. We recommended no change in status. http://ecos.fws.gov/docs/five_year_review/doc2518.pdf (Latest info on this species.) DESCRIPTION The callippe (ca-LIP-ee) silverspot is a medium-sized butterfly in the brush foot family (Nymphalidae). It has a wingspan of about 5.5 centimeters (2.2 inches). The upper wings are brown with extensive black spots and lines, and the basal areas are extremely dark. The undersides are brown, orange-brown and tan with black lines and distinctive black and bright silver spots. The basal areas of the wings and body are densely hairy. The caterpillars are dark- colored with many branching sharp spines on their backs. Identification of the subspecies is challenging in some parts of its range because it can hybridize with Lilian’s and Comstock’s silverspot butterflies, producing offspring that are intermediate in appearance. Life History and Ecology The callippe silverspot butterfly has one flight of adults per year. It undergoes complete metamorphosis (a structural transformation during the development of an organism) from egg to larval, pupal and adult stages. Egg Stage During the early summer flight season, females lay their eggs on the dry remains of the larval food plant, Johnny jump-up ( Viola pedunculata ), or on the surrounding debris.

  • "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.

    Effect of different grazing regimes on Viola pedunculata populations at King Ranch - 2010 December 16, 2010 Prepared by: Elizabeth Bernhardt Tedmund Swiecki Prepared for: Sue Wickham Solano Land Trust 1001 Texas Street, Ste C Fairfield, CA 94533 P HYTOSPHERE R ESEARCH 1027 Davis Street, Vacaville, CA 95687-5495 707-452-8735 email: [email protected] URL: http://phytosphere.com 2010 - King Ranch V. pedunculata grazing study Page 2 of 16 SUMMARY This report discusses second year results of a study that investigates how specific changes to the grazing regime at King Ranch affects cover of Viola pedunculata, the larval food plant of the Callippe silverspot butterfly. In 2007, we established plots in six clusters of three plots each at widely spaced locations on the ranch, with three clusters on each of two common soil types. Cover in these plots was read in spring 2007 and 2008 to serve as a baseline. One plot in each cluster was excluded from grazing early in the grazing season in 2009 and 2010. A second plot in each cluster was excluded from grazing late in the season in 2009 and 2010. The plots excluded from grazing did not differ in V. pedunculata cover or grass cover compared to plots which had not been excluded from grazing. Although grass cover and vegetation height were negatively correlated with V. pedunculata cover, excluding plots from grazing for short periods did not result in V. pedunculata cover differences. Vegetation height and cover were correlated with precipitation during the growing season. Due to the interactions that exist between grazing impacts and weather, we recommend that the study be continued for at least two to three more years, so that treatment effects can be assessed over a wider range of weather conditions.

  • Lepidoptera of Albany Hill, Alameda Co., California
    LEPIDOPTERA OF ALBANY HILL, ALAMEDA CO., CALIFORNIA Jerry A. Powell Essig Museum of Entomology University of California, Berkeley and Robert L. Langston Kensington, CA November 1999; edited 2009 The following list summarizes observations of Lepidoptera (moths and butterflies) at Albany Hill, Alameda Co., California, during 1995-1999. Data originate from about 75 daytime and crepuscular visits of 0.5 to 3.5 hrs, in all months of the year. All of the butterfly species and some of the moths were recorded by RLL, most of the moth species and their larval host plants by JAP. A total of 145 species is recorded (30 butterflies, 115 moths), a modest number considering the extent and diversity of the flora. However, many of the potential larval host plants may be present in too small patches to support populations of larger moths or butterflies. Nonetheless, we were surprised that colonies of some of the species survive in a small area that has been surrounded by urban development for many decades, including some rare ones in the East Bay region, as annotated below. Moreover, the inventory is incomplete. A more comprehensive census would be accomplished by trapping moths attracted to ultraviolet lights. In a habitat of this size, however, such survey would attract an unknown proportion of species from surrounding areas. Larval collections are indicated by date-based JAP lot numbers (e.g. 95C37 = 1995, March, 37th collection). Larval foods of most of the other species are documented in other populations. Host plants are recorded at Albany Hill for 75 species (65% of the moths, 52% of the total); the rest were observed as adults only.

SUMMARY Developmental constraints have been proposed different characteristics of microsporogenesis, only cell to interfere with natural selection in limiting the available wall formation appeared as constrained. We show that set of potential adaptations. Whereas this concept has constraints may also result from biases in the correlated long been debated on theoretical grounds, it has been occurrence of developmental steps (e.g., lack of successive investigated empirically only in a few studies. In this article, cytokinesis when wall formation is centripetal). We document we evaluate the importance of developmental constraints such biases and their potential outcomes, notably the during microsporogenesis (male meiosis in plants), with an establishment of intermediate stages, which allow emphasis on phylogenetic patterns in Asparagales. Different development to bypass such constraints. These insights are developmental constraints were tested by character discussed with regard to potential selection on pollen reshuffling or by simulated distributions. Among the morphology.
