Abstrak

Sabana ternyata juga terdapat di dataran tinggi, seperti sabana yang terbentuk di lereng Gunung Rinjani dan Gunung Tambora. Informasi tentang kedua sabana tersebut belum banyak diketahui dibandingkan dengan sabana lain di Indonesia Penelitian ini bertujuan untuk mengkaji dan membandingkan karakteristik dan variasi komposisi komunitas tumbuhan sabana di dataran tinggi G. Rinjani dan G. Tambora. Metode pengambilan sampel dilakukan secara purposive (dengan awal acak) di sepanjang Sabana untuk mendapatkan informasi kelimpahan jenis tumbuhan berkayu dan juga kelimpahan jenis penutup tanah. Data vegetasi dianalisis dengan Analisis Kesamaan (ANOSIM), CLUSTER dan SIMPER dengan menggunakan perangkat lunak PRIMER V.6. Tercatat ada 45 spesies tumbuhan yang termasuk dalam 27 famili di dua sabana tersebut. Kedua sabana memiliki keanekaragaman spesies yang hampir sama (1,72 untuk G. Tambora dan 1,85 untuk G. Rinjani). Saccharum spontaneum, Desmodium sp., Ziziphus rotundifolia, Acacia nilotica, dan Tabernaemontana sp. hanya terdapat di G. Tambora, sedangkan Dicranopteris linearis, Stachytarpeta indica, Engelhardia spicata, Ocimum sp., Vanda sp., Rubus sp., dan Nephrolephis sp. hanya ditemukan di G. Rinjani. Imperata cylindrica banyak ditemukan dan berpotensi memicu kebakaran liar di kedua sabana tersebut. Invasi spesies asing invasif, seperti Acacia nilotica mulai terjadi di G. Tambora.
