ABSTRACT: The
main threat to the existence of pitcher plants (Nepenthes spp) in the protected
forest of mount semahung areas caused by human activities such as illegal
logging and land clearing. Therefore, conservation efforts should be made in
order to remain sustainable existence. The research aimed to know the diversity
of pitcher plants (Nepenthes spp) inthe protected forest of Mount Semahung. The
method of research was observational,sampling used double plots (20 m x 20 m)
as much as 20 plots, each plots consisted of 16small plots with size 5 m x 5 m.
The research slowed that in the protected forest of Mount Semahung, there were
268 Nepenthes spp consisted of N. mirabilis, N. ampullaria, N. gracilis, N.
hirsuta, and N. reinwardtiana. Based on Importance Value Index (IVI), N. mirabilis
(IVI = 33.0495) and N. ampullaria (IVI = 31.5495%), were species thatdominant
with IVI values were respectively, rather than N. Gracilis (IVI = 9.9222%), N. Hirsuta
(IVI = 7.0354%), and N. Reinwardtiana (IVI = 4.7736%). Dominance index value,
species diversity index, and abundance index for each type of pitcher plants (Nepenthes
spp) categorized as low as it had a value less than one.
