Background and Aims:
The aim of the proposed project is to sustainably conserve the remaining endangered dugong (sea cow) population of Busuanga Island, in the Province of Palawan, Philippines. The project will gather solid scientific information with the cooperation of local communities in order to create conservation strategies that fully involve local communities and incentivize them to protect their dugongs and associated natural resources.
The dugong (sea cow) is one of the Philippines’ most threatened marine mammals. Although historically, dugongs have been sighted on almost all of the islands of the Republic, the remaining dugong populations are sparse and scattered. Palawan is regarded as the dugong’s final stronghold in the Philippines and is the most promising hope for the species’ national survival.
Dugongs were previously hunted using nets, prong, hook, spear, harpoon, and dynamite and the meat sold openly in public markets. Nowadays,incidental capture in fishing nets is likely the most significant threat to the species. Gill nets, seines, trawls, and bag nets have been identified to have caught dugongs. Additionally fish corrals, locally known as baklad have been known to capture dugongs. There are no quantitative data on mortality estimates due to lack of monitoring capabilities. The species is put under further pressure because of degradation of its seagrass habitat due to increased coastal development and population growth.
A significant step forward in Filipino dugong conservation occurred in 1991 with the issuance of DENR Administrative Order No. 55, which made the dugong the first marine mammal protected in Philippine waters. As stipulated in this AO, any person who shall hunt, kill, wound, take away, possess, transport and/or disposes of a dugong, dead or alive, its meat or any of its by-products shall be punished by imprisonment from 6 months to 4 years or fined Php 500 to 5,000 or both. This order was the result of several years of internationally supported effort to initiate dugong conservation activities in the Philippines, involving aerial surveys, interviews, habitat mapping and awareness-raising activities.
However, there is a clear need to re-ignite dugong conservation in the Philippines to sustain the momentum initialized by these projects which occurred more than 10 years ago. The main obstacles currently facing dugong conservation in the Philippines include: lack of funding, insufficient scientific information on population size and threats and ineffective implementation of national laws.
The dugong is reliant on shallow coastal seagrass and thus shares almost all of its habitat and natural resources with humans. Therefore, in order to successfully protect dugongs in the Philippines, it is essential that the human component is well-considered. The support and involvement of local communities is key to ensuring the continuation of the dugong in the Philippines.
Project activities:
-Population assessment: we will use key-informant interviews and in-water surveys to evaluate the status of Palawan’s dugongs. This information will provide current data on the size and viability of the remaining population.
-Habitat mapping: we will map seagrass meadows identified as important habitat for dugongs. This work will provide information on feeding ecology and degree of habitat degradation.
-Awareness-raising and community reporting: we will use novel community-based social marketing methods to promote dugong conservation throughout Palawan. We will also develop and improve existing fisher reporting project to ensure that dugong deaths are reported and necropsied if possible.
-Incentivizing communities- we will incentivize environmental stewardship of coastal habitats and species using the dugong as a flagship species by facilitating livelihood improvement opportunities in the form of small community grants for sustainable projects proposed by community members based on their socioeconomic needs.
-Training of UP students – we will train at least 10 students from the University of the Philippines in dugong and seagrass survey techniques.
Project objectives:
1. To assess and monitor the status of the dugong population of Palawan and its associated habitat degradation
2. To raise awareness and develop a fisher reporting programme
3. To develop community incentive programmes, stewardship plans and sustainable livelihoods
4. To train University of Philippines students
5. To create a policy brief to contribute to National dugong protection legislation
Conservation importance of this work:
Currently dugongs are classified as vulnerable to extinction under the 2009 World Conservation Union (IUCN) Red List of Threatened Species, which indicates that they face a high-risk of extinction in the wild in the medium-term future. Furthermore, the Convention on the Conservation of Migratory Species of Wild Animals (CMS) lists the dugong in its Appendix II, meaning that the conservation of the species would benefit from international cooperative activities organized across the dugong’s migratory range. Dugongs are also listed under Appendix I of the Convention on the International Trade on Endangered Species of Wild Fauna and Flora (CITES) as a species threatened with extinction.
The Seagrass ecosystems on which these species depend are important not only for the survival of the dugong but also for a plethora of other marine biodiversity. Seagrass ecosystems provide important habitat and breeding grounds for many marine species, including important fishery species that millions around the globe depend on daily for their livelihoods. The economic benefits to coastal communities of seagrass protection cannot be overstated: i.e. shrimp and fish use these ecosystems as development grounds. Local artisanal fisheries depend on these habitats to supply for to a growing community of hundreds of millions.
Dugongs are effective flagship species which can support biodiversity conservation and ecosystem based management of coastal seagrasshabitats, while promoting protection for the sources of livelihoods upon which millions of families depend. The dugong’s vulnerability to adverse anthropogenic influences puts them in the front lines of many insidious and compounding threats across their extensive geographical range. Due to the dugong’s precipitous decline and the scientific consensus that the species will disappear from the majority of its range without significant conservation interventions, its long-term survival of the dugong will be contingent on effective conservation and collaborative management throughout its extensive range. Using dugongs as a flagship species, the project would not only provide significant improvement in its survival rates but also the protection of seagrass and associated mangrove and reef ecosystems, wider improvements in coastal biodiversity and environmental services including preservation of fish nurseries, increasing coastal carbon sequestration, and buffers from climate change impacts.
