Diversity Of Natural Orchids And Their Habitat At The Lore Lindu National Park
: This study aimed to understand the diversity of natural orchids, their habitat in the lowlands, Sub Mountain, mountain and alpine, as well as biotic and abiotic environment factors influenced the diversity of orchids at the Lore Lindu National Park. Methodology: This study was conducted in several locations at the Lore Lindu National Park by selecting places that represent various type of orchids growing in the lowland with an altitude of 600 m above the sea level, sub mountain of 1,000-1,500 m above the sea level, mountain of 1,500-2,000 m above the sea level and alpine of 2,000-2,600 m above the sea level. Those places were the lowland of Bobo village, the sub mountain of Kamarora, the mountain of Danau Kalimpa’a and the alpine of Rore Katimbu. This study was conducted from November 2018 to April 2019. We employed vegetation analysis using the path-shaped method, the shape, and size of the observation path and its placement on each pioneering line if it meets the type of orchid. Results: Based on the identification results, we obtained 45 species of orchids with an abundance of 238 individuals and 26 orchid genera in each observation area. This results showed that variety of Spathoglottis plicata Bl., Arundina bambusifolia Lindl., Dendrobium stratiotes Rchb.f., Phaius tankervillae (Bl.).Lindl. were dominant types. Distribution of species from 45 species were identified as a whole, lowland areas and alpine areas have the same species diversity that was as many as 22 species (48.88%), then in the mountain area as many as 16 species variations (35.55%) and the rest in the area submountain as many as 12 species variations (26.66%). Conclusion: The (e) orchid evenness index in the Lore Lindu National Park area is categorized as having a moderate level of uniformity. Lore Lindu National Park found several types of orchids that have the potential as a source of germplasm, this type of orchid is one type of endemic orchids and includes rare orchids namely Grammatophyllum stapeliiflorum, Phaelaenopsis celebiensis dan Bulbophyllum echinolabium, Coelogyne asperata Lindl, Coelogyne speciosa Lindl, Cymbidium finlaysonianum Lindl dan Phaius tankervillae (BL) Lindl.
