Mangroves are plants typical of tidal boundaries, beaches and around river mouths. Mangrove vegetation in Induha Village is spread along the coast. Information regarding the structure and composition of mangrove vegetation is still lacking, so research is needed. This research was conducted to determine the structure and composition of mangrove vegetation in Induha Latambaga Village, Kolaka Regency. This study used the point centered sampling method and the observed parameters were seedlings, saplings and trees as well as the composition of the mangrove vegetation. The results showed that Rhizophora apiculata had the highest relative dominance in seedlings (42.13%), saplings (57.50%) and trees (38.31%). Relative frequency in seedlings (35%), saplings (45%) and trees (34.5%). Relative LBA for seedlings (50%), saplings (84.83%) and trees (52.34%). KR in saplings (57.2%) and trees (35.5%), as well as IVI in seedlings (136.1%), saplings (248%) and trees (148.1%). Vegetation composition consisted of 3 families (Rhizophoraceae, Acanthaceae and Sonneratiaceae) and 4 species (R. apiculata, R. mucronata, R. stylosa and B. cylindrical). Environmental factors in Induha Village support the survival of mangroves, especially Rhizophora apiculata.

Pantai Kalomang merupakan salah satu tempat wisata favorit di Kabupaten Kolaka. Pantai Kalomang ini bertempat di Desa Gunung Sari, Kecamatan Watubangga, Kabupaten Kolaka. Alasan pemberian nama Pantai Kalomang oleh warga setempat, karena keberadaan Kelomang atau Umang-umang yang sangat melimpah di pantai tersebut. Namun, yang menjadi permasalahnnya adalah belum ada data resmi dari Desa Gunung Sari Kecamatan Watubangga atau Pemerintah Daerah Kabupaten Kolaka tentang data pola distribusi dan kelimpahan populasi serta data taksonomi kelomang di pantai Kalomang tersebut. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengetahui pola distribusi dan kelimpahan kelomang di Pantai Kalomang Kecamatan Watubangga Kabupaten Kolaka. Metode yang digunakan dalam penelitian ini adalah metode survey eksploratif yang dibatasi dengan garis transek dan penentuan stasiun menggunakan metode purposive sampling yang didasari dengan faktor fisik lingkungan di Pantai Kalomang. Analisis data spesies dianalisis dengan deskriptif kualitatif sedangkan pola distribusi menggunakan teknik analisis kuantitatif. Hasil identifikasi diperoleh 75 individu kelomang laut yang terdiri dari satu suku dan 3 jenis, yaitu Caenobita cavipes, Caenobita compressus, dan Caenobita rugosus. Hasil penelitian ini menunjukkan bahwa kelimpahan populasi kelomang laut berkisar antara 1 ind/m2 – 2 ind/m2. Analisis kelimpahan secara umum menunjukkan tingkat kelimpahan yang rendah. Indeks Morisita menunjukkan pola distribusi kelomang laut di Pantai kalomang termasuk kategori mengelompok (Id > 1) dan seragam (Id < 1).
