Oberbauer, Luciana Luna Mendoza, Nadia Citlali Olivares, Lucía Barbosa Deveze, Isabel Granillo Duarte, and Scott A. Morrison ..... 3 Guadalupe Island continues to exhibit a remarkable recovery of native vegetation following the removal of feral goats. A recent fire in the remnant groves of endangered Guadalupe cypress caused unexpectedly high mortality of adult trees. What enabled that relatively low intensity fire to kill the large trees was that the trees had been scarred by goat browsing and that damage to the trunk allowed the fire to kill the tree. Fortunately, the fire also triggered a tremen- dous dispersal of cypress seeds and the likely rejuvenation of the forest. A DYNAMIC TOOL FOR SOUND LANDSCAPE MANAGEMENT: INTRODUCING THE SECOND EDITION, A MANUAL OF CALIFORNIA VEGETATION by Todd Keeler-Wolf and Julie M. Evens.................................. 12 Since the first edition of A Manual of California Vegetation was published 15 years ago, significant changes have occurred. Thousands of new field samples have been col- lected and analyzed, and the classification of vegetation types has been refined and expanded. The second edition includes detailed information on life history and ecology of the State’s vegetation, and is expected to contribute significantly to better management of Cali- fornia’s natural landscapes. AWARD WINNERS OF THE PHOTOGRAPHY AND BOTANICAL ART CONTESTS FROM THE CNPS 2009 CONSERVATION CONFERENCE by Josie Crawford ............................................................ 19 In discussing the science connected to conservation issues, it is easy to lose sight of why we are so engaged in these discussions. This is precisely why planners of the CNPS 2009 Conservation Conference decided to sponsor two contests, one for photography and the other for botanical art. The images that follow eloquently express an appreciation for California’s native flora.

  • Behavioural Responses of White Sharks to Specific Baits During Cage
    www.nature.com/scientificreports OPEN Behavioural responses of white sharks to specifc baits during cage diving ecotourism Edgar E. Becerril‑García1,2, Edgar M. Hoyos‑Padilla2,3*, Primo Micarelli4, Felipe Galván‑Magaña1 & Emilio Sperone5 This study describes the efect of diferent baits on the attraction, surface behaviour and conditioning of white sharks Carcharodon carcharias during local ecotourism activities. The sightings, behaviours, and pictures used for photographic identifcation were obtained during August to November 2012– 2014 onboard tourist boats in Guadalupe Island, Mexico. Four types of baits were used: (1) frozen bait; (2) frozen bait and natural chum; (3) fresh fsh bait; and (4) mackerel bags. Data were analysed according to sex, maturity and the total of sharks using 6,145 sightings of 121 white sharks. The type of bait showed no signifcant diference on the efectiveness to attracting sharks. Ethological analysis showed that the type of bait had a signifcant efect on the shark’s surface behaviour during its interactions with boats. Natural chum and fresh baits showed short term behavioural patterns constituted by increased number of violent interactions with the bait, while the frozen bait did not generate a defned behavioural pattern. Conditioning of white sharks was determined by the number of interactions and the consumption frequency of the bait. Fifty nine percent of sharks (n = 41) showed no conditioning, 36% (n = 25) showed a low risk and only 5% (n = 3) were found to have a high risk of conditioning. The results suggest that current ecotourism has no efect on the conditioning of the white sharks, and that all baits have a similar efectiveness for attracting the sharks.

  • Pacific Seabird Program Business Plan (Dawson Et Al
    National Fish and Wildlife Foundation Business Plan for Pacific Seabirds (Update) September 2016 Pacific Seabirds | 1 Purpose of a Business Plan The purpose of a NFWF business plan is to provide a detailed blueprint of the strategies and resources required to achieve the desired conservation outcomes. The strategies discussed in this plan do not represent solely the Foundation’s view of the actions necessary to achieve the identified conservation goals, but instead reflect the majority view of the many federal, state, academic, and organizational experts that were consulted during plan development. This plan is not meant to duplicate ongoing work but rather to invest in areas where gaps might exist so as to support the efforts of the larger conservation community. Acknowledgements We thank everyone who contributed to this business plan. We are especially grateful to the seabird experts, funding partners, and working group teams who took the time to develop, contribute, and review material. We acknowledge the contributions of Dantzker Consulting, Advanced Conservation Strategies, and Clarus Research for their evaluation of the Pacific Seabird Program and recommendations for continued implementation of this program. We also wish to acknowledge the valuable input resulting from discussions and written material provided by implementation and funding partners including (but not limited to): The American Bird Conservancy, BirdLife International, The David and Lucille Packard Foundation, The Farallon Institute, Island Conservation, the National Audubon Society, National Park Service, National Oceanographic and Atmospheric Administration, Oikonos, University of California Santa Cruz Coastal Conservation Action Lab, The University of Washington, The U.S. Fish and Wildlife Service, The U.S.

  • Appendix D5 Restore Seabirds to Baja California Pacific Islands
    Appendix D5 Restore Seabirds to Baja California Pacific Islands Appendix D5 Restore Seabirds to Baja California Pacific Islands Appendix D5 Restore Seabirds on the Baja California Pacific Islands The Natural Resource Trustees for the Montrose case (Trustees) have evaluated a variety of seabird restoration actions for the Baja California Pacific islands in Mexico. These islands support a wide range of seabirds that nest in or use the Southern California Bight (SCB). Restoration efforts would target a suite of seabird species, including the Cassin’s auklet, Brandt’s cormorant, double-crested cormorant, California brown pelican, ashy storm-petrel, and Xantus’s murrelet. To streamline the evaluation of these actions, the general background and regulatory framework is provided below. Detailed project descriptions are then provided for the following islands: (1) Guadalupe Island, (2) Coronado and Todos Santos Islands, (3) San Jeronimo and San Martín Islands, and (4) San Benito, Natividad, Asunción, and San Roque Islands. The actions discussed in this appendix do not cover all of the potential seabird restoration actions for the Baja California Pacific islands; therefore, the Trustees will consider additional actions in the future for implementation under this Restoration Plan, as appropriate. D5.1 GENERAL BACKGROUND The Baja California Pacific islands are located in the northwestern portion of Mexico, off of the Pacific coast of Baja California (Figure D5-1). Of the 12 islands or island groups (18 total islands) in this region, nine present unique opportunities for seabird restoration. Three of these islands or island groups (Coronado, Todos Santos, and San Martín) are oceanographically considered part of the SCB.

Abstract As the fi rst step towards the ecological restoration of its islands, Mexico has completed 60 eradications of invasive mammals thanks to a strong partnership between Grupo de Ecología y Conservación de Islas, A.C. (GECI), the federal government, local fi shing communities, academia, and private donors. The removal of invasive mammals has led to the dramatic recovery of the islands’ ecosystems. On Guadalupe Island, after completing the goat eradication in 2007, the native vegetation started to recover. Plants considered extinct or extirpated have been rediscovered, and plant species new to the island have been recorded.

Fig. 487 Phocarctos hookeri Distinctive Characteristics: Hooker’s sea lions have a muzzle that is fairly broad; the top is either fiat or slightly rounded. The ear pinnae are small and inconspicuous. The vibrissae are moderate in length, reaching as far back as the pinnae on some animals. In adult males, the neck and shoul- ders are greatly enlarged, and there is a mane of thicker and longer hair from the nape to the shoul- ders, and the chin to the chest. The head appears small. Adult females are much smaller and thinner than males through the neck, chest, and shoul- ders; the head and muzzle are narrower or less DORSAL VIEW domed than in males. At birth, pups are dark brown with a lighter crown and nape; a pale stripe extends from the crown to the nose, including the mystacial area. Pups be- gin to moult their birth coat at 2 months. Adult females and subadults of both sexes are silvery grey to brownish grey above and tan to pale yellow below. The demarcation between light and dark is high on the neck and usually extends over the insertion of the flippers. The light coloration often extends above the ears (which can appear high- VENTRAL VIEW lighted) to the eyes, and down the sides of the muzzle, There is considerable variation in the extent of dark and light areas, particularly on the head.
