Abstract

Kehadiran dan kemelimpahan Komodo (Varanus komodoensis) dipengaruhi oleh kondisi vegetasi sebagai habitatnya. Belum pernah ada kajian terhadap vegetasi habitat komodo yang ditampilkan dalam bentuk profil hutan. Ada dua lokasi yaitu di Flores sebagai Pulau Besar dan Ontoloe sebagai Pulau Kecil. Kedua lokasi didominasi oleh ekosistem karst. Lokasi kajian di Riung terdiri dari Cagar Alam (CA) Wolo Tado dan CA Riung. Sebaliknya di Pulau Ontoloe termasuk dalam Taman Wisata Alam Laut (TWAL) 17 Pulau sejak tahun 1992. Penelitian ini bertujuan untuk mengkaji profil vegetasi habitat Komodo di pulau besar yaitu daerah Riung dan pulau kecil yaitu Pulau Ontoloe. Pengambilan data dilakukan dengan metode kuadrat plot dengan bantuan transek yang memotong lokasi kajian. Ukuran plot pada ekosistem hutan bakau, hutan ekoton dan hutan legong 20m x 20m dengan ulangan 4x. Sedangkan padang rumput yang jarang pohon, ukuran plot 100m x 100m dengan ulangan 4x. Gambar profil diambil dari data yang mewakili vegetasi habitat komodo. Hasil yang diperoleh bahwa Riung dan Ontoloe memiliki tipe ekosistem meliputi ekosistem hutan bakau, hutan ekoton, dan hutan bukit. Ketinggian profil mulai dari 0,03 m sampai lebih tinggi dari 10 m. Strata profil hutan ada first layer, second layer dan third layer. Heteropogon concortus tetap lestari di Riung dan Pulau Ontoloe sehingga menjadi sumber pakan herbivora yang akan menjaga pakan V. komodoensis. Pohon dan sapling menjadi tempat perteduhan bagi herbivora. Pengetahun profil ini akan mendukung perilaku konservasi vegetasi sebagai habitat komodo.

Distribution and abundance of Komodo dragon (Varanus komodoensis) influenced by vegetation as their habitat. The study about vegetation profile of Komodo dragon’s habitat in Riung and Ontoloe Island in East Nusa Tenggara is a new. Riung’s location is in Big Island or Flores and Ontoloe as Small Island. They are dominated by karst ecosystem. Riung have Wolo Tado and Riung as Cagar Alam (CA). But Ontoloe Island include in Taman Wisata Alam Laut (TWAL) 17 Pulau since 1992. The purposes are to study about verrtical and horizontal diagrame of vegetation profil in Big Island and Small Island. We use plot quadrat with transect. Plot in mangrove ecosystem, ecotone and legong were 20m x 20m with replication 4 times. In sabana woodland, plot was 100m x 100m because the trees were rare, replication 4 times. Vegetation profile drawn from representative datas. The result that in Big and Small Island had some types of ecosystem: mangrove, ecotone and hills. Profile of forest starts form 0,03 – 10m, vertically with first. Heteropogon concortus sustains in Riung and Ontoloe then will support herbivore as Komodo dragon’s prey. Trees and sapling become canopy for herbivores. This study will inform and support people’s knowing and conservation acts in Komodo dragon’s habitat.
