Diversity of Rattan species in production forest in Central Sulawesi, Indonesia

Abstract

This study aims to explain the diversity of rattan species from production forests in Central Sulawesi. Data collection was carried out with a strip random sampling scheme, in which the sampled strips were 20 x 100 m. Our observation revealed that in the production forest area in Parigi Moutong and Sigi Regencies about 17 species of rattan were identified, which were divided into two genera, each with 14 species of Calamus and 3 species of Daemonorops. The distribution of eleven species was uniform, the distribution of four species was not uniform, and three species had a clumped distribution. The importance of each species varies. There are 8 species with a relatively high mean importance value: Calamus zollingerii (36.62), Calamus ornatus var. celebicus Becc. (24.62), Calamus oodersianus Becc. (23.56), Calamus ornatus var. celebicus Becc. (lambang) (23.49), Calamus didymocarpus (Mart) Becc. (22.99), Calamus inops Becc. (22.25), Calamus sp. (sambuta) (18.00), and Calamus lejocaulis Becc. (15.82), while C. minahassae (dato) has the lowest importance value (6.05). It disclosed, the number of species and distribution of rattan in the production forest of the Central Sulawesi are relatively high and varies.
