PETA SEBARAN POPULASI Amorphophallus titanum (Becc.) Becc. ex Arcang DI LAMPUNG, SUMATERA: UPAYA MENUJU PROPOSAL KE IUCN Red Data List DAN KONSERVASI Ex Situ

Abstract

Amorphophallus titanum (Becc.) Becc. ex. Arcang belongs to Araceae family. The genus Amorphophallus consists of 220 species which is distributed in tropical and subtropical countries worldwide. About 26 species have been recorded in Indonesia or 11.6 % of the total Amorphophallus in the world. Sumatera Island has the highest endemic Amorphophallus species, encompasses 11 species, of which seven species are endemic, such as A. titanum . The presence of A. titanum in its natural habitat has been alarmed. The lowland forests of Sumatera have been widely converted into agricultural and housing, thus may affect the rate of extinction of A. titanum in nature. The aim of this study is to provide the distribution map of A titanum in Lampung. Several sites in national parks, protected forests and community forests were observed for the research. This research was carried out from 2011 to 2016 using explorative method. The results showed that less than 10 mature individuals of A. titanum were found in each location. This indicates that this species is vulnerable, or even leading to extinction in future if not immediately protected. The result of this research will proposed for reassessing the conservation status of A. titanum . All specimens of A. titanum collected from the forests are cultivated in Liwa Botanic Garden and Bogor Botanic Garden as an ex situ conservation action for the species.
