This study aims to determine the distribution map of <em>Xylocarpus</em> sp species and population character of <em>Xylocarpus </em>sp in North Halmahera Regency. This research was conducted from April to June 2021. The method used included a mapping survey of <em>Xylocarpus</em> sp by recording the coordinates from GPS for each <em>Xylocarpus</em> sp found. Determination of population character of <em>Xylocarpus</em> sp was done by observing plant morphology related to vitality and periodicity. Data analysis was carried out by processing coordinate data and observational data on the character of the population of <em>Xylocarpus</em> sp into a base map through a GIS application. The results showed that the species <em>Xylocarpus </em>sp. found in North Halmahera district was Xylocarpus granatum. The distribution pattern of <em>Xylocarpus granatum</em> in North Halmaera is spread in groups. Population characteristics show <em>Xylocarpus granatum</em> in very low sociality conditions, vitality in a well-growing state, periodicity in flowering and fruiting conditions.</p>}, number={1}, journal={Jurnal Biologi Tropis}, author={Tolangara, A.R and Amalia R.L, Nurul and Mas’ud, Abdu and Sundari, Sundari}, year={2021}, month={Dec.}, pages={98–104} }
