Some coastal areas of the Poteran Island had covered by mangrove that associated to benthic macrofauna and had given an ecologically value. This study was aim to determine the trend of living of benthic macrofauna on mangrove tree species at certain parts such as roots, stems, leaves, or substrate. Benthic macrofauna sampling had done using the random method with hand collecting at one meter squares of each area of mangrove zonation. Illustration of benthic macrofauna living tendency on mangrove zonation showed using multivariate Canoco. Dispersal pattern of benthic macrofauna in mangrove zonation calculated manually using Poisson Index. The population of benthic macrofauna that associated with mangrove zone of Avicennia marina, Sonneratia alba and Rhizophora apiculata respectively were 3, 10 and 10 species, while the pattern of dispersal of macrofauna associations had a tendency to cluster (clumped) in the zone of Avicennia marina, Sonneratia alba and Rhizopora apiculata, except for some specific types such as Cerithidea cingulata, Metopograpsus latifrons and Gaffrarium pectinatum that showed random pattern.
