The Profile of Dipterocarpaceae In Momiwaren Protected Forest in South Manokwari District West Papua

Abstract

The family Dipterocarpaceae is one of the families which dominated tropical forest in lowland area, but the existence of this type is very restricted in eastern Indonesia region. Information about Dipterocarpaceae is imperative because there are different types of Dipterocarpaceae which have been listed in the category of endangered status. Therefore, research is required to obtain data about the potency of the family Dipterocarpaceae in West Papua region. The method used for collecting data at tree and stake levels was continuous strip sampling method while at sapling and seedling levels was line plot sampling method with nesting plot. The data were analyzed to obtain density value, frequency, and important value index (IVI). The result of this study found three types of Dipterocarpaceae namely Vatica rassak, Anisopthera thurifera and Hopea iriana. Vatica rassak had the highest IVI at tree level as 14,302 and the lowest level was the poles level as 9,90. Mean while, species H. iriana had INP of 0,176% at the seedling level and 0,114 at sapling level. Tree and pole levels were not found to this species. Based on stratification type, Vatica rassak had B stratification with the height between 20 and 30 m
