Resiko ancaman kepunahan biawak Komodo di CA Wae Wuul

Pada populasi kecil, dibawah 200 individu (Lande et al 2000), seperti halnya biawak Komodo di Flores – termasuk CA Wae Wuul, resiko kepunahan menjadi sangat tinggi (Purvis et al, 2000) karena :

1. Pada populasi kecil potensi untuk berkembang biak sangat rendah akibat sedikitnya dan terpencarnya individu yang dapat bereproduksi. Pada populasi biawak Komodo di CA Wae Wuul, potensi untuk terjadinya perkawinan sangatlah rendah akibat terpencarnya individu-individu (lihat peta sebaran komodo di Wae Wuul).
2. Pada populasi kecil yang memiliki masa “life history” lambat (usia matang seksual untuk kawin dan masa mengerami telur yang lama) memiliki tingkat kepunahan tinggi karena resiko kematian lebih tinggi dari pada potensi rekrutmen. Biawak Komodo diketahui memiliki pola life history yang lambat, di mana usia matang seksualnya pada usia 5 tahun dan mereka bertelur tidak setiap tahun. Selain itu di Wae Wuul hingga saat ini tidak ditemukan lokasi yang berpotensi digunakan untuk bersarang.
3. Populasi kecil yang berada pada puncak rantai makanan, seperti halnya biawak Komodo, sangat rentan terhadap gangguan yang terjadi pada mangsanya. Berdasar survey KSP pada 2008 dan 2009, Mangsa biawak Komodo di CA Wae Wuul, khususnya rusa, sangatlah rendah (grafik) dibandingkan dengan kondisi mangsa di TN Komodo di mana populasi biawak Komodo di sana relative lebih aman.
4. Populasi kecil pada jenis-jenis yang memiliki wilayah jelajah sangat luas memiliki resiko kepunahan sangat tinggi karena dampak gangguan yang terjadi di dalam wilayah jelajahnya, seperti kehilangan dan gangguan habitat, perburuan, serta kompetisi dengan jenis lain, akan sangat berpengaruh. Biawak Komodo dewasa diketahui memilki luasan wilayah jelajah 2.78-5.4 km2, sementara di wilayah sekitar CA Wae Wuul sangat rawan terjadi kebakaran hutan, padang rumput, konversi habitat, perburuan rusa, bahkan tindakan manusia yang menganggap biawak Komodo sebagai ancaman baginya, yang secara langsung sangat berpengaruh terhadap tingginya resiko kepunahan biasak Komodo di CA Wae Wuul.
Terlepas dari argument di atas, hingga saat ini populasi biawak Komodo di Flores termasuk di CA Wae Wuul belum mendapat perhatian yang cukup baik dari sisi kajian ilmiah maupun dari sisi pengelolaan (monitoring berkala, pengamanan, atau pembinaan habitat), sehingga masih diperlukan kajian lebih mendalam untuk dapat menentukan layak tidaknya pengambilan individu dari populasi ini. Kami menyarankan adanya rencana pemantauan dan perlindungan khusus untuk populasi Komodo yang tersisa di Cagar Alam Wae Wuul.

Latest news from the Wae Wuul Protection Plan for Komodo Dragons January 17, 2008

Latest news from the Wae Wuul Protection Plan for Komodo Dragons

Posted: 02/07/2007
The Wae Wuul Protection Plan is based on the island of Flores in Southeast Indonesia. In 2001, population densities of Komodo dragons on this island were estimated at 1 individual per 20 hectares. This is a marked decrease from surveys in 1991, probably caused by human-related pressure on natural habitats in the Wae Wuul Reserve, through poaching, cultivation of land and collection of firewood.

The 2006 Komodo dragon conservation programme commenced in the dry season in July 2006. Administration issues with the local authorities were dealt with in July, with staff from Komodo National Park and the Nature Resources Conservation Office working on a long term agreement regarding joint management of the Wae Wuul Reserve. A Non-Governmental Organisation, the Komodo Survival Programme, was formed early in 2007, requesting that the European Association of Zoos and Aquaria act as a supervisor of this Komodo dragon conservation project.

Field activities followed in August and September 2006 devoted to community awareness activities and patrolling of the Wae Wuul Reserve. Community awareness activities are vital for regular interaction with the members of the 8 villages living outside the reserve to show continuous commitment to conservation, to help minimise the levels of encroachment in Komodo dragon habitat and to explain the long term effects of intensive poaching on wildlife in the reserve. Lectures in the community awareness programme covered descriptions of the current status of the reserve and its wildlife, a review of policies against cultivation and exploitation of the reserve and an outline of the activities to promote conservation and monitoring. Soon after the community awareness programme, patrolling activities commenced, conducted solely by the villagers and representatives of the Indonesian Department of Forestry. These patrols took place on alternate days in September, along 5 patrolling paths. Throughout such patrols, the villagers recorded feral dogs, signs of hardwood cuttings, a fire along the reserve boundary, and goat and water buffalo herds within the reserve boundary. These results indicate a reduced human pressure compared to 2005, possibly indicating the effectiveness of patrolling activities in the last 2 years. The feral dogs still, however, pose a threat as they hunt deer, a prey species of the Komodo dragon.

It is hoped that once the Wae Wuul Protection Plan becomes established as a regular, annual initiative then such activities within the park boundaries will stop completely and Komodo dragon numbers will increase.

Perjalanan dimulai dari Labuan Bajo menuju pos jaga CA Wae Wuul melalui beberapa desa di sekitar kawasan CA Wae Wuul. Kegiatan ini dilakukan untuk meninjau kondisi pos jaga dan kondisi kawasan di sekitar pos jaga. Berikut beberapa temuan yang perlu dilaporkan dari hasil pengamatan di lapangan;

  1. Kondisi pos

Kondis pos jaga yang dibangun pada tahun 1996 sudah dalam keadaan rusak. Beberapa bagian pos sudah rusak parah dan perlu segera diperbaiki. Kerusakan tersebut adalah :

    1. Instalasi air seperti bak air sudah retak dan rusak parah, pipa banyak yang patah, bak sumber air terlalu pendek.
    2. Lantai retak-retak,
    3. Kamar mandi dan septiptank tidak berfungsi,
    4. Tidak terdapat ruag dapur,
    5. Plafon rusak parah,
    6. Instalasi listrik rusak parah,
    7. Ventilasi dan sirkulasi cahaya matahari kamar tidur tidak memadai,

  1. Rencana perbaikan

Beberapa hal perbaikan pos jaga yang menjadi prioritas adalah sebagai berikut;

perbaikan instalasi air, termasuk perbaikan bak penampungan air dan menyediakan satu bak air atau saluran khusus untuk keperluan masyarakat sekitar pos jaga

perbaikan lantai

perbaikan dinding, termasuk pemindahan jendela dan perbaikan ventilasi

perbaikan atap dan plafon

QUICK REPORT

WAE WUUL NATURE RESERVE RANGER STATION VISITATION

In regard of Collaboration preparation between Komodo Survival Program and the Balai Besar Konservasi Sumber Daya Alam NTT.

A field trip to visit Wae Wuul Nature Reserve was conducted on December 16th, 2007, as part of our partnership with KSDA NTT to implement capacity building and conservation project of Komodo dragon and it’s environment on Flores. From the field trip, we identified several key findings that are important to implement.

  1. Renovation of Ranger Station.

Current ranger station is urgently to renovate as it is important to provide a more suitable condition for the rangers, volunteers, researchers, and stakeholders to utilize the station as basecamp of conservation works in WWNR.


  1. Reconstruction of zonation.

Most of the border marks (Pal, In Bahasa Indonesia) are missing. Thus the border in which separating nature reserve area and private land is unclear. This situation is could potentially causing a conflict between WWNR authority and local communities around the reserve area.

  1. Developing biodiversity and key species data base.

To date, no scientific information on biodiversity potential of WWNR is available as basic for the reserve authority to design and implement appropriate conservation and management strategies. Thus biodiversity assessment and documentation as well as developing data base are necessary to undertake.

  1. Developing specific study, monitoring and conservation strategies of Komodo dragon including the habitat.

Considering the habitat of Wae Wuul, a specific monitoring and conservation strategies of Komodo dragon and other key species, including the habitat should be considered to design. This requires a comprehensive assessment of potential and threats. Broad scale involvement of various stakeholders is necessary.

  1. Capacity building.

To enhance capacity and human resource skill of KSDA NTT staff in managing Komodo dragon and other key biodiversity in WWNR, capacity building activities, i.e trainings should be implemented. Specific trainings should be carried out base on the needs and priority that important to the management in WWNR.
