Composition of tree species at the ebony forest in the watershed area of sausu, Central Sulawesi, Indonesia
Abstract
Diospyros celebica Bakh. (Makassar ebony) is one of endemic tree species to Sulawesi and prized of its luxuriant, multicolour wood grain. It has been used for long history of use even in Ancient Egyptian. Modern use of ebony are largely restricted to small items, such as crucifixes, musical instrumen parts including piano, viola, guitar, bass and for furnitures. The objectives of this research is to determine the composition of tree species and its condition in watershed area. It is expected that the result can be used as a references in the conservation of ebony species both in-situ or ex-situ. The structure and composition was studied in the watershed Sausu Central Sulawesi, Indonesia which is largely natural dispersal area of ebony stripes by using vegetation analyses methods. Geographically located between 120 ° 13’45,33 “-120 ° 32’10,22” E and 1 ° 5’3,94 “-1 ° 59’29,50” S. 3 (three) lines transects were established at the altitude 100 – < 250 m asl, 150-400 m asl and 400-550 m asl respectively. Each altitutude was sampled in 10 subplots with 2 ( two) replicates, so in total there are 18 lines. The result showed that the riparian vegetation composition Sausu classified as poor types. It was dominated by Koodersiodendron pinnatum Merr, Canarium littorale. Homalium foetidum Benth, Diospyros celebica Bakh and Pometia pinnata Bl. (except on slopes with an altitude of 100 to <250 m asl). The species of Diospyros celebica Bakh. in the studied area have abundant of seedlings, but the trees that has Diameter Breats High (D.B.H) > 50 cm is very less. Conservation activities should be done species Diospyros celebica Bakh to maintain its sustainability.
