Conservation of Proboscis Monkey (Nasalis larvatus) Habitat in Suwi Wetland

Conservation of Proboscis Monkey (Nasalis larvatus) Habitat in Suwi Wetland

Objective of this project is to rehabilitate proboscis monkey habitat, as part of maintaining Danau Mesangat and Kenohan Suwi Wetland Esential Ecosystem which is important for water precipitation, flood control, habitat for wildlife as well as center of inland fisheries. Most information available about proboscis monkey in coastal area, Suwi wetland is about 104 kilometers from est coast of Kalimantan. These multi-year projects funded by Keidanren Nature Conservation Fund (KNCF) Japan. 

Yasiwa carried out project ‘Conservation of Proboscis Monkey (Nasalis larvatus) Habitat in Suwi Wetland’ during periode of April 2017 –March 2018, April 2019-March 2020 and April 2020-March 2021. Most of the field work done in cooperation with local fisherman, students of Mathematics and Science Faculty of Mulawarman University.  Local fishermans are knowledgeable group and who should get the most benefit since they are the ones who lost their livelihood.  Yasiwa concern to give opportunity to the students to gain field experience and motivate graduates working on field conservation.

1.Proboscis Monkey survey

Initial study of proboscis monkey done by Tri Atmoko, S.Hut., M.Si, expert from BALITEK (Research and Conservation Technology Development of Natural Resources Agency under Ministry of Forestry), Periodic survey during the project develop in informations :

    • Twelve groups of proboscis monkey found, 6 groups in upstream, 5 groups in downstream and 1 group in Loa Bekara.
    • Identified 12 food plants among 60 plant species, with the highest score is Litsea oppositifolia and the second is Barringtonia acutangula.
    • Recommend to plant Malllotus sumatranus, Baringtonia acutangula and Syzygium lenietum beside Dillenia excelsa for habitat rehabilitation.    
    • The peak hour of activities is 4 to 6 pm.

4. Replanting and maintenance

 Planted cutting more than 5000, mostly Dillenia excelsa, food plant of Proboscis  Monkey and has wide leaf to create shade for controling the invasive Mimosa pigra.  Planted fruit trees 16 in drier river bank. 

5. Conservation Education 

Two training for teachers surrounding the wetland to develop understanding about wetland.

First training (2017): consist of field observation, group discussion, presentation, environmental games and provide biodiversity poster, to enable the teacher to introduce biodiversity to the student. Direct observation to the wetlands is the first experience for most of the participant even though they live next to the wetland. 

Second Training (2019) consist of guidance from Education Office of East Kutai District, how to develop extracurricular lesson plans about the wet lands

Information center initiated to support learning process for student and teacher.  Information center development and training has been held in cooperation with Ulin Foundation.

Inisiasi Pengelolaan Lahan Basah Suwi (2013-2015)

Inisiasi Pengelolaan Lahan Basah Suwi (2013-2015)

Muara Ancalong Merupakan kecamatan tertua di Kabupaten Kutai Timur, dengan ibu kota kecamatan di Kelinjau. Kelinjau berjarak sekitar 133 km dari Samarinda, ibu kota Provinsi Kalimantan Timur.

Lahan basah Suwi terletak di bagian barat desa Kelinjau, terdiri dari Danau Suwi yang dikenal secara lokal sebagai Kenohan Suwi, Danau Serapung, Danau Ketiau dan beberapa danau kecil dengan dataran banjir di sekitarnya. Lahan basah tersebut merupakan habitat bagi mamalia endemik dilindungi, yaitu bekantan (Nasalis larvatus) dengan status terancam punah, juga terdapat buaya siam dan banyak jenis burung air.

Berdasarkan peta tata ruang Kabupaten Kutai Timur (2013-2032), lahan basah Suwi, Mesangat dan sekitarnya terletak di atas Cekungan Air Tanah Sendawar. Lahan Basah Suwi bagain Timur juga berbatasan dengan Cagar Alam Muara Kaman Sedulang. Semestinya lahan basah dikelola agar tetap memberikan jasa ekosistemnya. Namun demikian lahan basah mengalami degradasi karena pemanfaatan yang tidak sesuai untuk perkebunan sawit.

Yasiwa mempromosikan pengelolaan lahan basah berkelanjutan. Sinergi peran parapihak antara pemerintah, dunia usaha, perguruan tinggi, kelompok masyarakat dan LSM untuk mencapai pengelolaan yang lebih baik memerlukan upayan yang tidak mudah dan perlu terus didorong.

Pada tahun 2015 Ditjen Bina Pengelolaan Ekosisitem Esensial-KLHK dibentuk untuk mengelola ekosistem penting di luar kawasan dilindungi, seperti area bernilai Konservasi tinggi yang berada dalam konsesi perusahaan. Melalui kerja sama Yasiwa dengan Kabupaten Kutai Timur Lahan Basah Mesangat dan Suwi diusulkan untuk dikelola dengan skema Ekosistem Esensial oleh para pihak. Forum Pengelolaan Kawasan Ekosistem Esensial Lahan Basah Mesangat Suwi dibentuk berdasarkan SK Bupati pada bulan Oktober 2016.

Untuk proyek inisiasi di Suwi ini Yasiwa mendapat dukungan pendanaan dari ZGAP, EAZA dan Dortmund Zoo untuk kegiatan meliputi:

  • Survei Habitat dan inventarisasi keragaman hayati
  • Mendorong parapihak untuk pengelolaan lahan basah secara layak guna menjada jasa ekologinya
  • Memperkenalkan nilai penting lahan basah kepada anak-anak sekolah dan parapihak
  • Pencatatan tinggi muka air bekerja sama dengan nelayan
  • Menguatakan nelayan untuk mengurangi perburuan dan penyetruman ikan
