UNEP Caribbean Environment Programme, Kingston, Jamaica. 2010 Caribbean Environment Programme United Nations Environment Programme REGIONAL MANAGEMENT PLAN FOR THE WEST INDIAN MANATEE (Trichechus manatus) Compiled by: Dr. Ester Quintana-Rizzo Dr. John E. Reynolds III Manatee (Trichechus manatus) © Manatee P r o g r a m m e , Mote Marine Laboratory Prepared in collaboration with: CEP Technical Report 48 2010 ii PREFACE The Caribbean Environment Programme (CEP) is one of several Regional Seas Programmes administered by the United Nations Environment Programme (UNEP). The CEP is based in Kingston, Jamaica, and forms the programmatic framework for the Convention for the Protection and Development of the Marine Environment of the Wider Caribbean (Cartagena Convention) adopted in 1983 by governments of the Wider Caribbean Region. The Cartagena Convention is the only comprehensive environmental umbrella treaty for the region, promoting regional cooperation to protect the economic and environmental sustainability of the region through improved management of coastal and marine resources. To achieve its objectives, the Convention has established three Protocols for environmental management: the Protocol Concerning Cooperation in Combating Oil Spills, the Protocol Concerning Specially Protected Areas and Wildlife (SPAW), and the Protocol Concerning Land-Based Sources and Activities of Marine Pollution (LBS). The purpose of the SPAW Protocol is to protect rare and fragile ecosystems and habitats, thereby protecting the endangered and threatened species residing therein. This Protocol was adopted in 1990 and, in 1991, the participating governments adopted three Annexes to the SPAW Protocol listing species of flora and fauna of regional concern requiring protection under the Protocol. The SPAW Protocol became international law in 2000. This document was prepared following Articles 11 and 21 of the SPAW Protocol, which call for the development of general guidelines and criteria for the management and recovery of endangered and threatened species of regional concern. This document also updates UNEP-CEP Technical Report Number 35 published in 1995 and entitled “Regional Management Plan for the West Indian manatee, Trichechus manatus,” to promote more effective research and conservation. The marine mammal fauna of the Wider Caribbean Region is diverse and adds significant ecological, aesthetic and economic value to Caribbean countries and territories. Success in managing and conserving marine mammals in this region ultimately will depend largely on the commitment of participating countries to build their internal capacities and to work cooperatively by establishing conservation priorities, standards and strategies for marine mammal conservation and education. Since 1995 governments participating in the SPAW Protocol have considered conservation of the Antillean subspecies of the West Indian manatee (Trichechus manatus manatus) as a regional priority. The subspecies is found in waters of nearly 20 countries or territories, but its distribution is patchy, abundance is very low in most countries, and adverse impacts of humans are or may be considerable. This report is based on in-depth consultation with scientists and managers from the various States and Territories of the Wider Caribbean Region; including both Parties and non-Parties of the SPAW Protocol. All comments and recommendations were considered in preparation of the final document, which was submitted for approval and on 8 September 2008, endorsed by the SPAW Parties at their Fifth Conference of the Parties in Antigua. Based on the wide range of opinions considered, this report recommends both traditional measures for manatee conservation (e.g., improved education and awareness; enforcement) and novel ones (e.g., re- iii introduction into historic habitat) that have proven effective for conserving other endangered species and, if based on sound scientific guidance, may prove useful for manatees. Not all scientific experts (including the authors) necessarily agree with every recommendation or its relative priority. This report does not reflect full scientific consensus, as the issues involved are too complex. Rather, it presents a synthesis of issues and approaches that Parties of the SPAW Protocol should consider and, if deemed appropriate, implement. The UNEP-CEP thanks everyone who contributed in any way to the development of this document. In particular, UNEP-CEP thanks the Government of France for providing funding through the SPAW Regional Activity Centre in Guadeloupe, and Drs. Ester Quintana-Rizzo and John Reynolds, of Mote Marine Laboratory (Sarasota, Florida) for their dedication to this effort and technical expertise. We hope that it will facilitate more effective conservation of manatees in the Wider Caribbean.

O’SHEA§i *Department of Wildlife and Range Sciences, University of Florida, Gainesville, FL 32611, U.S.A. ‡College of Natural Resources and Environment, Box 118100, University of Florida, Gainesville, FL 32611, U.S.A. §National Biological Service, Sirenia Project, 412 NE 16th Ave., Gainesville, FL 32601, U.S.A. Abstract: Recent development of age-determination techniques for Florida manatees (Trichechus manatus lati- rostris) has permitted derivation of age-specific data on reproduction and survival of a sample of 1212 car- casses obtained throughout Florida from 1976–1991. Population viability analysis using these data projects a slightly negative growth rate (20.003) and an unacceptably low probability of persistence (0.44) over 1000 years. The main factors affecting population projections were adult survival and fecundity. A 10% increase in adult mortality would drive the population to extinction over a 1000-year time scale, whereas a 10% decrease in adult mortality would allow slow population growth. A 10% decrease in reproduction would also result in extinction. We conclude that management must focus on retaining and improving the conditions under which manatee demography operates. The major identified agent of mortality is boat-manatee collisions, and rapidly increasing numbers of humans and registered boats portend an increase in manatee mortality. Zon- ing of manatee-occupied waters for reductions in boating activity and speed is essential to safeguard the manatee population. If boating regulations being implemented by the state of Florida in each of 13 key coastal counties are completed, enforced, and effective, manatees and human recreation could coexist indefi- nitely.

The new discoveries in the Grand Cul-de-Sac Marin are of a completely different nature. Following reports in 2012, surveys were organized: a sample of 160 lithic pieces scattered on the seabed between 2.50 m and 4 m deep was taken more than 1 km offshore. It is macrolithic tools in andesite. The most spectacular are axes blades and abrasive tools such as grinding stones, grinders, mortars and circular polishers. There are also elongated pebbles bearing percussion marks attesting to their use as hammers. The status of this vast deposit is still undetermined.

ABSTRACT WEST INDIAN MANATEE (TRICHECHUS MANATUS) HABITAT CHARACTERIZATION USING SIDE-SCAN SONAR by Mindy J. McLarty Chair: Daniel Gonzalez-Socoloske ABSTRACT OF GRADUATE STUDENT RESEARCH Thesis Andrews University School of Arts and Sciences Title: WEST INDIAN MANATEE (TRICHECHUS MANATUS) HABITAT CHARACTERIZATION USING SIDE-SCAN SONAR Name of researcher: Mindy J. McLarty Name and degree of faculty chair: Daniel Gonzalez-Socoloske, Ph.D. Date completed: April 2017 In this study, the reliability of low cost side-scan sonar to accurately identify soft substrates such as grass and mud was tested. Benthic substrates can be hard to classify from the surface, necessitating an alternative survey approach. A total area of 11.5 km2 was surveyed with the sonar in a large, brackish mangrove lagoon system. Individual points were ground-truthed for comparison with the sonar recordings to provide a measure of accuracy.

  • Nishiwaki, M., T. Kasuya, N. Miyazaki, T. Tobayama and T. Kataoka. Present Distribution of the Dugong
    PRESENT DISTRIBUTION OF THE DUGONG IN THE WORLD MASAHARU NISHIWAKI University of the Ryukyus, Naha, Okinawa TOSHIO KASUYA Ocean Research Institute, University ef Tokyo, Tokyo NOBUYUKI MIYAZAKI National Science Museum, Tokyo TERVO TOBAYAMA Kamogawa Sea World, Kamogawa, Chiba AND TERVO KATAOKA Toba Aquarium, Toba, Mie ABSTRACT This is a result of hearing surveys on dugong distribution in the past 10 years. The species is distributed widely in the Indo-Pacific Ocean, between the longitude of 30°E and l 70°E, and between the latitude of 30°N and 30°S. Although nothing is known on movement and seasonal migration of the species, discontinuity of distribution or of density suggests the presence of at least five populations. They are (1) east Australian and east Papua New Guinean group, (2) west Australia-Molucca-Philippine group, (3) Sumatura­ Malaysia-Andaman group, (4) Indo-Sri Lanka group and (5) east African and Madagascar group. Their range might have been continuous before depletion by human activities, and the first three populations may still be continuous dispersely. The forth and fifth group seems to be on the verge of extinction. The total population of 30,000 individuals is roughly presumed by Nishiwaki. INTRODUCTION Since the Human Environment Conference of the United Nations held at Stockholm in 1972, conservation of marine mammals has been called loudly. Particularly calls were concentrated on cetaceans. Then conservation on sirenians followed as a matter of concern. Studies on the dugong and the species of mana­ tees have progressed at the same time (Bertram, 1976). The first step needed for conservation is to clarify the habitat, range of dis- Sci.

No, I'm fine’: A note on YES and NO in South Africa Theresa Biberauer Theoretical and Applied Linguistics, University of Cambridge, United Kingdom, and General Linguistics Department, Stellenbosch University, South Africa E-mail: [email protected] Marie-Louise van Heukelum General Linguistics Department, Stellenbosch University, South Africa Email: [email protected] Lalia Duke General Linguistics Department, Stellenbosch University, South Africa Email: [email protected] Abstract This paper considers some unusual uses of NO and YES observed in South African English (SAE) and other languages spoken in South Africa. Our objective is to highlight the fundamentally speaker-hearer-oriented nature of many of these elements, and to offer a formal perspective on their use. We also aim to highlight the value of pursuing more detailed investigations of these and other perspectival elements employed in SAE and other languages spoken in South Africa. Keywords: negation, affirmation, speaker-hearer perspective, clause structure, pragmaticalisation 1. Introduction1 Our point of departure in this note is the peculiarity of South African English (SAE) illustrated in (1): (1) A: How are you? 1 This paper had its origins in a lively discussion, in which Johan Oosthuizen also participated, during the first author's 2017 Honours Syntax seminar.

Building- Use your blocks to make a maze. Pretend that you have a dugong that is searching for seagrass. Have him follow the maze you built to make it to the grass at the end. This can be really fun to build if you have legos and a project board. Make the path just wide enough for a marble to roll through. Place the marble in your maze and tilt to board to help it roll through the maze. Science- You will need three clear cups, water, salt, food coloring (any color) and an ice cube. • Help your kids measure out one cup of water for each of the three cups. • Leave one alone and add two tablespoons of salt in the other two. Make sure to let your kids measure and pour. Stir the salt into the water to help it dissolve.

Email: *[email protected], [email protected] 2Cameroon Wildlife Conservation Society (CWCS), Coastal Forests and Mangrove Programme Douala-Edea Project, BP 54, Mouanko, Littoral, Cameroon. Email:[email protected] * Corresponding author Abstract An ethnobiological survey of 174 local resource users was conducted in the Lower Sanaga Basin to assess the current conservation status of West African manatee (Trichechus senegalensis, Link 1795) within lakes, rivers, and coast (including mangroves, estuaries and lagoons). Using a multistage sampling design with semi-structured interviews, the study asked three main questions: (i) are manatees still present in Lower Sanaga Basin? (ii) If present, how are their numbers evolving with time? (iii) What are the main threats facing the manatee? Each of these questions led to the formulation and formal testing of a scientific hypothesis. The study outcome is as follows: (i)60% of respondents sighted manatees at least once a month, regardless of habitat type (rivers, lakes, or coast) and seasons (dry, rainy, or both); (ii) depending on habitat type, 69 to 100% of respondents perceived the trend in manatee numbers as either constant or increasing; the increasing trend was ascribed to low kill incidence (due either to increased awareness or lack of adequate equipment) and to high reproduction rate; and (iii) catches (directed or incidental) and habitat degradation (pollution) ranked in decreasing order as perceived threats to manatees.
