Updated Biological Inventory Report for the Rancho Malibu Religious Memorial Project, 4000 Malibu Canyon Road, City of Malibu, California
November 18, 2015 Project Number 15-02065 Jake Jesson Assistant Project Manager Green Acres, LLC 22837 Pacific Coast Highway #775 Malibu, California 90265 Via Email: [email protected] Subject: Updated Biological Inventory Report for the Rancho Malibu Religious Memorial Project, 4000 Malibu Canyon Road, City of Malibu, California This letter report updates the previous findings of the Biological Inventory Report (BIR) for the Rancho Malibu Religious Memorial Project due to a change in the project scope and grading plan. An Environmental Impact Report (EIR) was first prepared for this site (CBA, 1997) and certified by the City of Malibu City Council (March 23, 1998) along with conditions of approval contained in Conditional Use Permit No. 96-005. A BIR was prepared for the project site by Rincon Consultants, Inc. (Rincon) in May 2007 for plans to build a 146 room luxury hotel. An updated report was prepared in September 2011 (Rincon) as part of a Coastal Development Permit (CDP) application and Site Plan Review. In February of 2012, Rincon conducted a native tree assessment. In 2011 a reconnaissance survey and BIR update was prepared by Rincon to support the applicant’s plans to change the project from the development of a luxury hotel to a religious memorial and cemetery. This BIR (October 2015) documents the changes in potential impacts to special-status biological resources as they relate to the revised scope and grading plan for the proposed religious memorial and cemetery. PROJECT LOCATION AND DESCRIPTION The project site is located in the central portion of the City of Malibu, immediately north of Pacific Coast Highway between Malibu Canyon Road and Civic Center Way at 4000 Malibu Canyon Road. -

It is closely related to Baccharis plummerae subsp. plummerae but differs in having narrow, subentire, typically conduplicate, sparsely villous to mostly glabrous leaves with glands occurring in depressions on the adaxial surface, more cylindrical inflorescences, and a distribution in open chaparral vegetation. The new taxon shares some characteristics with B. plum merae subsp. glabrata of northwestern San Luis Obispo County, e.g., smaller leaves, reduced vestiture, and occurrence in scrub habitat, but the two taxa appear to have developed independently from B. -
Title Text Here Watershed 2011 Accomplishments
Alluvial Scrub Native Plants for the Upper Santa Ana River Title text here Watershed 2011 Accomplishments This project was initiated to develop science-based plant lists and local plant materials for restoration of alluvial scrub habitats within the Santa Ana River Watershed. This project is a collaborative effort between the U.S. Forest Service’s Pacific Southwest Region, NRCS Area Resource Conservation Agencies, a local organic farm, and the California Native Plant Society (CNPS). During April 2011, a second training workshop for volunteers in relevé and rapid assessment sampling techniques was hosted by Irvine Ranch Conservancy and the Riverside-Corona Resource Conservation District (R- CRCD) and CNPS. The CNPS completed data analysis of 49 plots from this project and legacy data from other alluvial sage scrub sites. Plots were classified into 14 associations and 12 alliances. Potential plant lists for restoration sites and species suitable for seed production will be identified from the analysis results. Seed collection for grow-out trials is now in progress (Figure 1).

College Avenue Claremont, Calif. 91711 ABSTRACT The Liebre Mountains form a discrete unit of the Transverse Ranges of southern California. Geo graphically, the range is transitional to the San Gabriel Mountains, Inner Coast Ranges, Tehachapi Mountains, and Mojave Desert. A total of 1010 vascular plant taxa was recorded from the range, representing 104 families and 400 genera. The ratio of native vs. nonnative elements of the flora is 4:1, similar to that documented in other areas of cismontane southern California. The range is note worthy for the diversity of Quercus and oak-dominated vegetation. A total of 32 sensitive plant taxa (rare, threatened or endangered) was recorded from the range. Key words: Liebre Mountains, Transverse Ranges, southern California, flora, sensitive plants. INTRODUCTION belt and Peirson's (1935) handbook of trees and shrubs.

FACT SHEET: New Visitor Center at King Gillette Ranch
FACT SHEET: New Visitor Center at King Gillette Ranch GENERAL A new interagency visitor center will open in the Santa Monica Mountains National Recreation Area on June 9 at King Gillette Ranch, the historic heart of the Santa Monica Mountains. Under the terms of a cooperative management agreement, the Anthony C. Beilenson Interagency Visitor Center will be jointly managed by the National Park Service (NPS), California State Parks (CSP), Santa Monica Mountains Conservancy (SMMC), and the Mountains Recreation and Conservation Authority (MRCA). The surrounding parkland is managed by MRCA. Formerly a horse stable for the Gillette Mansion, the re-purposed building unifies the local, state, and federal parks for SMMNRA’s 35 million annual visitors and is a national model for cooperation and efficiency. Few locations in California offer in one setting the opportunity to understand a cross-section of California’s rich history, including sites that represent Native American settlement, Spanish missions and adobes, Mexican ranchos, California homesteading, and modern movie-making. The new interagency visitor center replaces an existing NPS visitor center located outside the boundary in a poor-visibility area. That center will be closed to promote greater efficiency. Complimentary two-hour parking is available adjacent to the visitor center. A larger parking lot administered by the MRCA is nearby for a $7 all-day permit. HISTORY The prehistoric Native American Chumash village of Talopop covers the western portion of the site. Extensive archeological records are still present today for what is believed to be the largest interior Chumash settlement in California. King C. Gillette, the razor magnate, purchased the ranch in 1926 and commissioned Wallace Neff, considered “Architect of California’s Golden Age,” to design the estate, which was completed in 1928. -

This paper Exine ultrastructure Á Palynology Á Pollen development Á reviews the evolutionary and developmental origins of this Self-assembly diversity in pollen structure using recent models based on the behaviour of colloids and formation of micelles in the differentiating microspore glycocalyx and primexine. The Introduction developmental model is consistent with observations of structures recovered by pollen wall dissolution. Pollen wall Compositae is not only the largest family of flowering diversity in Compositae is inferred to result from small plants (Funk et al. 2005), but is also remarkable for the changes in the glycocalyx, for example ionic concentration, great diversity of internal and external forms encountered which trigger the self-assembly of highly diverse struc- in its pollen grains (Figs. 1, 2). Many investigators have tures. Whilst the fine details of exine substructure are, made observations on Compositae pollen, ever since the therefore, not under direct genetic control, it is likely that invention of microscopy (for a comprehensive bibliography genes establish differences in the glycocalyx which define see Wortley et al. 2009) but the details were first docu- the conditions for self-assembly.
