Mead (1852-1936) visited central Colorado from June to September 1871 to collect butterflies. Considerable effort has been spent trying to determine the identities of the butterflies he collected for his future father-in-law William Henry Edwards, and where he collected them. Brown (1956) tried to deduce his itinerary based on the specimens and the few letters etc. available to him then. Brown (1964-1987) designated lectotypes and neotypes for the names of the butterflies that William Henry Edwards described, including 24 based on Mead’s specimens. Brown & Brown (1996) published many later-discovered letters written by Mead describing his travels and collections. Calhoun (2013) purchased Mead’s journal and published Mead’s brief journal descriptions of his collecting efforts and his travels by stage and horseback and walking, and Calhoun commented on some of the butterflies he collected (especially lectotypes). Calhoun (2015a) published an abbreviated summary of Mead’s travels using those improved locations from the journal etc., and detailed the type localities of some of the butterflies named from Mead specimens.

    June 12, 2019 ADDENDUM TO THE FY 2016/2017 GRAVITY SEWER IMPROVEMENTS PROJECT FINAL INITIAL STUDY/ MITIGATED NEGATIVE DECLARATION INTRODUCTION This environmental document is an addendum to the FY 2016/2017 Gravity Sewer Improvements Project Final Initial Study/Mitigated Negative Declaration (IS/MND), State Clearinghouse No. 2017122069, by the Ross Valley Sanitary District (the District). Amendments to the Final IS/MND1 for the project include: 1) addressing a change of construction methods, and 2) fulfilling requirements for submittal of a State Revolving Fund (SRF) application. These changes and additions to the project have necessitated further environmental review. As demonstrated in this Addendum, the IS/MND continues to serve as the appropriate document addressing the environmental impacts of these improvements pursuant to California Environmental Quality Act (CEQA). Background The IS/MND was prepared to address construction-level impacts to the existing deficient gravity sewer mains owned by the District in two areas: the Butterfield/Meadowcroft alignment (Butterfield alignment) and the Nokomis alignment (see Figures 2 and 3 in the IS/MND). The IS/MND evaluated potential environmental effects on aesthetics, agriculture and forestry, air quality, biological resources, cultural and tribal resources, geology and soils, greenhouse gas emissions, hazards and hazardous materials, greenhouse gas emissions, hydrology and water quality, land use and planning, mineral resources, noise, population and housing, public services, recreation,
  • Planning Butterfly Habitat Restorations

    Planning Butterfly Habitat Restorations

    Planning Butterfly Habitat Restorations Kim R. Mason Introduction Ecologists and entomologists in Britain and the United States have participated in numerous projects aimed at restoring, expanding, and mitigating losses of habitat for native butterflies. Some of these butterflies have been listed as threatened or endangered; others have been lost or are in decline in certain portions of their former ranges. The experiences and observations of these scientists illustrate potential needs and concerns when planning to restore or improve existing butterfly habitat. This paper will relate several cases in which complex biotic and abiotic interactions played important roles in the success or failure of butterfly habitat restoration and the reestablishment of butterfly populations. Although each butterfly species has its own unique combination of habitat requirements and life history, some fundamental principles concerning butterfly biology (New 1991) are significant in planning habitat restorations. Most caterpillars are herbivores, and many are specialists which feed on only one kind or a few related kinds of plants. Therefore, the presence of appropriate larval host plants is the primary requirement of habitat restoration. In addition, many butterfly species require that the larval food plant be in a particular growth stage, of a certain height, exposed to the proper amount of sunlight, or in close proximity to another resource. Adults typically utilize a wider range of plants or other resources as food, and flight gives them expanded mobility. However, adult dispersal ability varies from species to species. For some, physical features such as a few meters of open space, a stream, a hedge, or a change in gradient create intrinsic barriers to dispersal; other species routinely migrate long distances.

    State of California The Natural Resources Agency DEPARTMENT OF FISH AND GAME Biogeographic Data Branch California Natural Diversity Database STATE & FEDERALLY LISTED ENDANGERED & THREATENED ANIMALS OF CALIFORNIA January 2010 This is a list of animals found within California or off the coast of the State that have been classified as Endangered or Threatened by the California Fish & Game Commission (state list) or by the U.S. Secretary of the Interior or the U.S. Secretary of Commerce (federal list). The official California listing of Endangered and Threatened animals is contained in the California Code of Regulations, Title 14, Section 670.5. The official federal listing of Endangered and Threatened animals is published in the Federal Register, 50 CFR 17.11. The California Endangered Species Act of 1970 created the categories of “Endangered” and “Rare”. The California Endangered Species Act of 1984 created the categories of “Endangered” and “Threatened”. On January 1, 1985, all animal species designated as “Rare” were reclassified as “Threatened”. Animals that are candidates for state listing and animals proposed for federal listing are also included on this list. A state candidate species is one that the Fish and Game commission had formally noticed as being under review by the Department for addition to the State list. A federal proposed species is one for which a proposed regulation has been published in the Federal Register.

Sacramento Fish and Wildlife Field Office U.S. Fish and Wildlife Service Sacramento, California February 2010 5-YEAR REVIEW San Bruno Elfin Butterfly (Callophrys mossii bayensis) and Mission blue butterfly (Icaricia icarioides missionensis) I. GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed.

Please contact the Xerces Society for permission to use. ________________________________________________________________________ Profile prepared by Scott Hoffman Black and Mace Vaughan The Xerces Society for Invertebrate Conservation ________________________________________________________________________ SUMMARY The San Bruno Elfin inhabits rocky outcrops and cliffs in coastal scrub on the San Francisco peninsula. The San Bruno Elfin is restricted to a few small populations, the largest of which occurs on San Bruno Mountain. Its habitat has been diminished by quarrying, off-road recreation, and urban development. Development pressures on the San Francisco peninsula continue to grow, and the major threats to the butterfly— increased urbanization in the area, and loss of habitat by road construction and rock and sand quarrying—reflect this. Grazing may have encouraged the growth of exotic plants in the area. In the early 1980s, a habitat conservation plan was developed to allow development on San Bruno Mountain while minimizing the adverse effects on the San Bruno Elfin
