IUCN RESOLUTION ON DUGONGS

 

          Members  of  IUCN attending the World Conservation Congress in  Montreal,  Canada last  October  adopted  the following resolution on Threats to  Dugong.  This  resolution  gives additional  impetus to the preparation of a global action plan for the conservation of  sirenians, which  the  Sirenia  Specialist  Group has been working on now  for  several  years.   -   Amie Bräutigam (SSC Programme Officer)

 

Threats to Dugong

 

AWARE  that  the  dugong (Dugong dugon) is listed as Vulnerable in the  IUCN  Red  List  of Threatened Animals;


NOTING  that  the largest populations of the species in the world are thought to  reside  in  the waters of northern Australia and Papua New Guinea;

 

CONCERNED  that  there  has  been a rapid and catastrophic  decline  in  numbers  along  the Queensland coastline from Cape Bedford to Hervey Bay, a distance of over 1200 km;

 

AWARE  that  researchers have attributed the decline in numbers to drowning  in  commercial fishing and shark protection nets, to traditional hunting and, at the southern end of the area,  to decline in the seagrass beds essential for the species;

 

AWARE that increased tourist resort, marina development and other boating facilities that may increase  the  number  of boats in and along the Great Barrier Reef  and  southern  Queensland coast may threaten the dugong population;

 

ACKNOWLEDGING  that  along  this  coast groups of  indigenous  peoples  have  voluntarily ceased hunting of dugong until the population recovers;

 

ACKNOWLEDGING  ALSO  that  commercial fishers have agreed to  undertake  a  range  of special measures to prevent continuing dugong mortality;

 

NOTING  that  the Australian Government has recently allocated special funds to  undertake  a dugong  recovery  plan  consisting  of a programme of  management,  education  and  research designed to prevent further decline in dugong numbers;

 

The  World  Conservation  Congress  at its 1st Session in  Montreal,  Canada,  14-23  October 1996:

 

1.  CALLS UPON all States with dugong populations to undertake urgent measures  to  ensure that all steps are taken to prevent further decline of the species in their country;

 

2.   CALLS UPON the Chair of the Species Survival Commission to request the  Sirenia  Specialist  Group  to  complete and promote the implementation of the Sirenia  Action  Plan,  with special reference to the status of the dugong;

 

3.  CALLS  UPON  the  Director General to write to all governments  of  States  with  dugong populations, including the Australian Government, expressing concern and:

   

          a)  urging that an ongoing programme of funding be provided for full  implementation of Operative Paragraph 1;

           

          b) urging that coastal tourist resorts and marina developments be restricted to  locations  that  do not threaten the dugong populations along the Great Barrier  Reef  and  southern Queensland coastline.

     

          Note:  The  use of the term "indigenous peoples" in this Recommendation shall  not  be construed  as  having any  implications as regards the rights which may attach to  that  term  in international law.

 

 

 

WHY DO LOCAL PEOPLE CALL THE DUGONG "SEA PIG" AND NOT "SEA COW"?

 

          In  1991  Dr.  Paul  K. Anderson proposed a revision of  sirenian  popular  names  and suggested  introducing  the name "sea pig" instead of "sea cow" for the dugong  [see  Sirenews No.  16].  He  also referred to the fact that in Sri Lanka the dugong is  called  "cudalpandi"  in Sinhalese  and  "kadalpani"  in  Tamil, both of which translate as "sea  pig".  During  my  five years'  fieldwork on dugongs in Indonesia I also came across the names "babi laout" in  Malay and  "sakoko ka koat" in the local language of the Siberut islanders, both of which  mean  "sea pig".  In  the Indonesian Dictionary Purwadanuda the dugong is called "babi  duyung",  which means  "piggy dugong". Local fishermen in Thailand similarly use a word which  translates  as "sea  pig". After Anderson's article, however, the discussion of this subject did  not  continue, and  I found among members of the Sirenia Specialist Group little enthusiasm for debating  the vernacular-name issue.

          I  do  think  that this issue deserves more attention than it has received so  far,  since  it touches  upon  the  heart  of the feeding ecology of the dugong and  its  niche  in  the  seagrass ecosystem.  Even  more important, a change in popular name may have a positive  spinoff  for dugong  conservation, particularly in the regions where "pig meat" is a religious  taboo.  Apart from  this we should pay some respect to the knowledge of local people; there is no  place  for arrogance  here.  It is remarkable that all these local fisherfolk in different countries  and  even different regions within countries all refer to the dugong as "the pig of the sea".

          When  giving a closer look to the feeding ecology of the dugong, their approach  is  not as strange as it seems at first sight:

   · Anderson  already  mentioned that dugongs, like pigs, are "rooters" and not  "grazers"  and are  referred to as rhizome specialists, which is also confirmed by my research  findings in the Moluccas (De Iongh, 1996). The way they remove the substrate is more  similar to the rooting behavior of pigs than the grazing behavior of cows and other grazers.

   · Anderson   mentions   that   dugongs  are,  like  pigs,  omnivorous;   they   both   feed   on macroinvertebrates.  Dugongs are known (like pigs) to dig circular craters in search  of burrowing mussels.

   · I would like to add that dugongs, like pigs, are able to digest feed with a high fiber content. Murray (1981) suggests that dugongs are able to use up to 25% of the fiber fraction for energy, while pigs use 35% of the fiber fraction for energy (Van Wieren, 1996).

          I  think, therefore, that there are some very strong arguments for adopting  the  popular name  "sea  pig"  for  the dugong, with regard to both its  feeding  ecology  and  the  expected positive  conservation  impact  of  such a name change. I would like  to  appeal  to  readers  of Sirenews  to  write  me at the address below if they agree or disagree and  if  they  have  found local  names  in their region (any local name is welcome, be it "pig" or "cow").

SAFETY RULES FOR MANATEE AERIAL SURVEYS

 

          In  Sirenews No. 24 (October 1995) we published a set of safety  recommendations  for personnel  conducting  aerial  surveys.  The following Spanish  translation  of  these  has  been furnished by the Sirenia Project, Gainesville, Florida.

 

 

 

Reglas de Seguridad para Censos Aereos de Manaties

 

          Los censos aéreos de manatíes presentan un peligro especial para los biólogos  haciendo el  censo  debido a los aeroplanos pequeños que se usan normalmente  (se  pueden  sobrecargar fácilmente), el novel de vuelo relativamente bajo (generalmente 500 pies), los virajes  cerrados que se hacen frecuentemente para contar manatís (puede ocasionar stalling) y las rutas de vuelo sobre agua. A veces la dedicacióde los biólogos puede tornarse en un peligro si la  determinación  para terminar una misión interviene con su juicio referente a las condiciones del  tiempo, la  capacidad  de  su piloto y las condiciones del aeroplano. A continuación  se  enumeran  una serie de reglas de sentido común para el personal envuelto en censos aéreos de manatíes.  Estas no pretenden abarcarlo todo sino destacar algunos aspectos de las regulaciones provistas por  la Oficina  de  Servicios  de  Aeroplanos  (OAS por sus siglas en  inglés),  las  cuales  deben  ser acatadas  por todos los empleados del Departamento de Interior (DOI por sus siglas  en  inglés) en los Estados Unidos cuando participan en un trabajo relacionado a la aviación.

          Se  le agradece a la Sra. Burma Campbell del Servicio de Pezca y Vida Silvestre de  los E.U. por proveer la información utilizada para desarrollar estas reglas, por revisarlas y por  su interés y apollo constante.

 

 ·  El  aeroplano Cessna 172 no tiene suficiente poder para un vuelo de bajo  nivel  (menos de  500  pies). Durante misiones de bajo nivel el aeroplano no puede  funcionar  legítimamente  con una carga certificada mayor (aeroplano, pasajeros,  combustible,  cargamento)  a  la recomendada por el fabricante. Si se planifica llevar más de  dos  observadores se recomienda un Cessna 182, 185 6 206.

 

 ·  Los  censos  nunca  deben hacerse a una altitud menor de  500  pies.  Muchos  biólogos prefieren  una altitud de 750 pies para dar vueltas y contar manatíes en grupos. Bajo  la política  de  aviación del DOI la tripulación del aeroplano no debe volar bajo  500  pies sin un entrenamiento especial y equipo protector personal.

 

 ·  Debe conocer la capacidad de su piloto. ¿Cuántas horas de vuelo tiene de experiencia el piloto,  con el aeroplano en el que se estará como pasajero? Las regulaciones  del  OAS piden 1000 horas de tiempo de vuelo para certificar a un piloto.

 

 ·  Debe  conocer  el registro de servicio de su aeroplano. La política de  aviació  del  DOI exige que un aeroplano reciba servicio e inspección cada 100 horas de tiempo de vuelo.

 

 · Prepare  una  lista de lo que Va/No va y revísela antes de cada vuelo.  Recuerde  que  a pesar  de  que  el piloto tiene la última palabra en la desición de  cancelar  el  vuelo.  Si usted  tiene alguna duda a cerca del tiempo, el piloto o el aeroplano, cancele  el  vuelo. Usted es mucho más importante que un censo que se pierda! Además, todos los  censos se  deben  hacer bajo condiciones óptimas de tiempo para poder  comparar  con  censos hechos  en  otras  fechas;  tiempo dudoso equivale a  resultados  de  censo  dudosos.  Si ocurren  cambios en el tiempo, el piloto o la condición física o mental  del  observador, el  observador debe cancelar la misión y dedir al piloto que regrese a la base o  a  tierra en el lugar más propicio, dependiendo de cuán drástico ha sido el cambio en las condiciones del vuelo.

 

 ·  Prepare  un  plan  de vuelo y déselo al personal entierra que está  en  el  aeropuerto  de donde  su  vuelo  despega y termina. La(s) persona(s) a quien usted le dé  el  plan  será respnsable  de seguir la trayectoria del vuelo y establecerá los procedimientos  de  búsqueda  y  rescate en caso de que su aeroplano no llegue a su destino luego de  una  hora del tiempo estimado de llegada.

 

 · Sólo  el  cargamento  y los pasajeros que sean esenciales para la misión deben  ir  en  el aeroplano.  Esto  no sólo elimina la posibilidad de que se accidente algo  que  no  debía estar  a bordo, sino que también mantiene el peso del aeroplano en el mínimo y  por  lo tanto  usa menos combustible y reduce los costos. Los biólogos deben tener cuidado  en aseguarar  los  utensilios que se utilizan a menudo como: lápices, bolígrafos,  lentes  de cámara, cubiertas de lentes, royos de película, grabadoras, etc.

 

 ·  La  política de DOI exige que el piloto esté presente para supervisar el tipo, contidad  y calidad del combustible utilizado en el aeroplano cuando se está repostando  combustible.  En EU han ocurrido desastres aéreos debido a reabastecimiento erróneo  en  donde combustible para jet se le ha puesto accidentalmente a un aeroplano de motor alterno.

 

 ·  Si  un aeroplano unimotor se va a utilizar a una distancia de la orilla más allá de la  que se puede recorrer planeando sin necesidad del motor, el aeroplano debe tener equipo de flotación y todas las personas a bordo deben tener su propio equipo de flotación.

 

 ·  Los  biólogos que tienen misiones de vuelo regulares podrían beneficiarse de  un  curso de familiarización de vuelo que consiste de 4 horas de teoría y 4 horas de entranamiento aéreo (el conso es aproximadamente $500.00). El mismo pretende darle a los  pasajeros  un conocimiento limitado de como manejar los controles, radios, etc...del  aeroplano y de como aterrizar el aeroplano en caso de una emergencia en donde el piloto se encuentre incapacitado.

 

          Comentarios sobre éstas regulaciones son bienvenidos. Si desea ayudar en traducirlas  a algún  otro idioma puede comunicarse conmigo. Si desea ejemplos de una lista Va/No va o  de un plan de vuelo o información sobre de familiarización de vuelo por favor comuníquese  con: Dr.   Lynn  Lefebvre,  Sirenia  Project,  U.S.  Geological  Survey  -   Biological   Resources Division,  412  NE  16th Avenue, Room 250, Gainesville, FL  32601   USA;  teléfono:  (352) 372-2571; fax: (352) 374-8080; Internet: sirenia@nervm.nerdc.ufl.edu

AUSTRALIA

 

          "Emergency" Measures to Increase Dugong  Protection in the Southern  Great Barrier Reef? - Readers of Sirenews will  be aware   of   the  serious  decline   in   dugong numbers  along a 2000-km stretch of the  east coast  of  Queensland. Aerial surveys  of  the more urbanized and intensively fished  southern  Great Barrier Reef indicate  that  dugong numbers declined by more than 50% between 1986/87   and  1994.  Dugong   numbers   in Hervey  Bay-Great Sandy Strait  immediately south  of  the Great Barrier Reef  region  also declined  by more than 50% after the loss  of >1000 km² of seagrass habitat in 1992.

          Last   November,  the  Great   Barrier Reef   Ministerial   Council   considered   the issue.   This  council is composed of  the  national and Queensland (state) ministers of  the Environment,  Primary Industries, and  Tourism.   The  Council  confirmed   that   urgent action  is  required to ensure the  recovery  of the  dugong  population in the  Great  Barrier Reef  and  adjacent waters and agreed  that  a chain  of interim "Dugong Protection  Areas" should  be established along this coast in  key dugong   habitats  at  approximately   200-km intervals. They also endorsed other  measures for  dugong  recovery and  conservation,  including  measures to reduce the likelihood  of dugongs drowning in commercial fishing nets or being injured by underwater explosives.

          Little  has changed. Mesh netting  has so  far been banned in only one area,  Shoalwater  Bay.  This bay is  the  most  important dugong  habitat along this coast. It  has  been protected from many anthropogenic  activities by  its  status  as  a  Military  Training  Area; however, the use of underwater explosives  is still  permitted  at one site in  this  bay.  Last month, the large-scale US-Australian military exercise   Tandem  Thrust  was  held  in   the vicinity of this bay.

          The  effectiveness  of  these  "Dugong Protection Areas" will depend on the political will to exclude mesh netting, control  boating activity,  reduce inputs from agriculture,  and control coastal development, and the  support of   Indigenous   groups   to   maintain   their moratoria  on  traditional hunting in  this  region.  So  far, the  Indigenous  peoples  have been by far the most cooperative  stakeholder group.   Given  that  their   association   with dugongs  goes back thousands of  years,  they understandably  consider they have  the  most to  lose  by the extinction  of  dugongs  along this coast.  -  Helene Marsh

 

BELIZE

 

     Manatee  Poaching  Continues  in  Belize.  - We at the Belize Center for  Environmental  Studies (BCES) are in the process  of writing  a management plan for the  proposed Port  Honduras Marine Protected  Area.   To become   more  familiar  with  this  area,   in particular   the   banks  between   the   Snake Cayes, I visited the area in October 1996.

      I  set  out by boat for the banks  off  East Snake  Caye with Larry Sauliner,  our  Peace Corps Environmental Educator, and his wife, a   Rural  Development  Officer  and  also   a Peace   Corps   volunteer.   After   about   40 minutes'  travel  north along  the  coast  from Punta  Gorda Town, we arrived in  the  Deep River area. I then said that if we saw vultures we should investigate what they were  eating, because  there was a rumor around town  that the   Guatemalans   were  over   here   killing manatees. By the time I finished saying  this, Ms. Sauliner pointed out some vultures.

     We  approached  the shoreline  where  the vultures  were. Entering the  mangroves,  we found  the  remains  of  five  recently-slaughtered  manatees.  The  skulls  were   cracked, apparently  with  a  hammer  or  other  metal tool. The persons responsible had cared  only for the prime parts; there was lots of decayed meat  on  the  bones, and the  fins  and  skins were  all  there. Some of the  skulls  were  of adult size and some were juveniles.

     Continuing  our  journey,  less  than  five minutes  away  we saw  more  vultures.  This time   there  were  four   freshly   slaughtered manatees.  Again,  the prime meat  had  been stripped off and the other meat left to rot.

     I  have  no  proof of  the  rumor  that  the meat from these manatees is going to Guatemala.  However,  I  am  in  the  field  almost every  day  and have never seen or  heard  of manatee  meat  for sale in Belize; but  I  have had  people  confirm  to  me  that  they  have bought the meat in Guatemala.

     Ten  minutes from the butchering site  are some  offshore cayes where fishermen  camp. These fishermen are mostly Guatemalans who have   valid  Belizean  fishing  licenses.   The fishermen  at these cayes have no  regard  for Belizean laws or the environment. I have  not seen  them  killing manatees but I  have  seen them  setting  their gillnets at  the  mouths  of rivers  and  on  some of our  reefs,  which  is illegal in Belize.

     As   a  concerned  Belizean   citizen   and BCES employee, I have informed the  appropriate government ministries, and am  calling on  them, on community groups, and  on  the NGO  community to come together  and  discuss  ways  to  resolve  this  problem.  I  also believe it is important to call upon our neighbors  from Guatemala and ask them  to  assist us in dealing with this urgent situation.

     About  a  year ago  BCES  facilitated  the visits  of  two scientists from the  USA,  who found  approximately 11 butchering sites  and an  estimated 35 manatee kills  [see  Sirenews No.  24]. The result was a press release;  but to  date nothing has been done except lots  of promises   from   some  donors  and   a   few pamphlets  received from the  Florida  Power and Light Company. Meanwhile,  discussions have   begun  with  the  Punta  Gorda   Town Police Department and the Fisheries Department.  In  the near future we will  meet  with the Toledo Community College  Environmental Club, local fishermen, Toledo Tour Guide Association,  and other organizations  to  discuss the possibility of volunteer patrols in the area.

     At this time BCES has no money for  this kind  of activity. However, BCES has  volunteered   to  lend  its  boat  for  patrolling   the waters. Before the patrols can take place,  we need  money for fuel, hand radios to call  for support   or  help  in  case   of   emergencies, binoculars,   spotlights,   batteries,   camping equipment  (including  tents,  hammocks,   or sleeping   cots,  portable  stoves,  etc.),   and some rain gear. We believe that much of  the poaching takes place on rainy nights.  -   Wil Maheia  (Field Specialist, BCES, P.

COLOMBIA

 

     Manatee     Poaching     Deplored     in Colombia.  -  Hans de Iongh sent  an  article from  the  Bogotá  newspaper  El  Tiempo  (9 Feb.   1997)  that  describes  an  instance   of manatee   poaching  and   discusses   manatee status in the province of Santander.  Excerpts follow:

     "ANOTHER   CRIME  AGAINST   THE MANATEE.  A group of  fishermen  clubbed to  death  four of six manatees  remaining  in the El Llanito marsh, in Santander.... Sixteen fishermen   corraled  and  killed   [the]   four manatees, including a cow and calf, to obtain two tons of meat, in what many regard as the worst  ecological  tragedy of recent  times  in this part of the country.

     "According to the director of the  Colombian  Institute  of Fisheries  and  Aquaculture (INPA)   in  Barrancabermeja,  Pedro   Julián Contreras,  there  were only six  manatees  in the marsh.

     "The  manatee was once abundant  in  the rivers, marshes, and mangroves of the  warm parts   of  the  country,  principally   on   the Caribbean  coast  and the  lower  and  middle Magdalena River. In the latter region,  which supposedly had the largest natural  concentration of manatees in Colombia, there are today only  35.  There are also some  in  Magangué (Bolivar).

     "These  animals  are  hunted  mainly   for their  meat, whose taste can be  mistaken  for that  of  bacon,  turkey,  cattle,  chicken,   or bagre  [a  freshwater fish], according  to  the part it comes from....

     "According  to  witnesses,  the  fishermen ensnared the manatees with nets, which  took them  almost  half  a  day.  Then  they  killed them  and held a manatee roast in the  village that  was attended by more than  100  people, including  the  police inspector of  the  town, who  is being investigated by the  authorities. The leftover meat was sold to fishmongers.

     "Paradoxically,   in  the  opinion  of   the experts,  the manatee is the  fishermen's  best friend, since it helps preserve the fauna of the places  where it lives, including the  fish.  Its ecological and economic importance is directly   proportional  to  its  gluttony....   If   the manatees  are exterminated, [floating  plants] grow  to excess, impede the passage of  light, and  kill  off microscopic algae  that  produce oxygen.  This ... reduces fishery  production, which  harms  the very  fisherman  who  contributes to the manatee's demise.

     "Public  prosecutors and  local  environmental  officials have begun an  investigation of  the poachers. The head of the  Magdalena Valley    Fishermen's    Association,    Pablo Emilio Tejada, pointed out that the killing  of these  animals serves to discredit  the  fishing community,  which has benefited  from  programs  to  restock  fish in  the  marshes.  The Regional  Autonomous  Corporation  of  Santander  (CAS)  asked the  El  Llanito  law-enforcement  community to economically  sanction  the  criminals  and  cancel  their  fishing licenses,  [or even impose] a  penal  sanction, which  could vary from fines to 1-5  years  in prison, under the laws in force.

     "While  the few surviving manatees in  El Llanito are being slaughtered, the  inhabitants of  ... Sabana de Torres and Puerto  Wilches, in Santander, offer protection and food to  20 manatees that live in the Paredes marsh...."

 

FLORIDA

 

     Disastrous Year for Florida Manatees. -  1996  was  the  worst  year  on  record  for manatee  mortality  in Florida,  even  without the spring die-off on the west coast due to red tide.  The  total  number  of  dead   manatees recovered was 415 (nearly twice the previous record),  of which 151 were attributed to  the red  tide  outbreak.  The  remaining  264  exceeded  the previous single-year (1990)  mortality  of 214 by almost 25%; the  total  1995 mortality  was  201.  The  264  non-red   tide deaths  broke  down  by  cause  of  death   as follows:   watercraft,  60;  flood   gates/ca
