Abstract

Hoya species are a type of epiphytic flowering plants that are known to have traditional medicinal values. Since 2011, eight Hoya species are recorded at the Bodogol Nature-Conservation Education Center (BNCEC), Bogor, Indonesia. For effective conservation measures, this study is aimed to analyze the population structure and distribution pattern of Hoya species at BNCEC. Data collection was done from July to August 2016 using a  purposive sampling method in a 400m2 plot. The results show that each species differed in their population structures. The H. multiflora population structure has the shape of an inverted pyramid, where there were more adult individuals than seedling and young ones, both H. campanulata and H. imperialis have the shape of a natural population pyramid, showing a population balance between seedling, young, and adult individuals. H. lacunosa has the shape of an hourglass, in which the number of seedlings and adult individuals is larger than the young. H. hasseltii and H. vitellinoides have no clear population structures as no adult individuals were discovered for these two species. The distribution pattern of Hoya populations at BNCEC is of the clumped type (Morisita’s index = 0.661).
