Spatial distribution and population characteristics of local durian (Durio spp.) in West Halmahera Island

Abstract

West Halmahera Island is one of the centers of durian production in North Maluku. The objective of this research is to make distribution maps of the population and characteristics of the local durian in West Halmahera Island. The research was conducted from April to June 2015, using the descriptive method with purposive sampling. The methods include mapping of local durian use recorded in terms of GPS coordinates. The population and characteristics of the fruit plants were observed using the plant morphology and associated vitality and periodicity. Data analysis was performed by processing the coordinate data and observational data for the population and characteristics of fruit plants through the application of a GIS base map. The spatial distribution of local durian in West Halmahera is found along the lowlands (21–139 m asl), with a grouping pattern. The condition of fruit plants grow well in a state of sprouting, flowering and fruiting
