Massoi (Cryptocarya massoy) is a plant species producing prominent NTFP in Papua. This species contains massoialacton used as a raw material for food, cosmetic, and pharmaceutical industries. The demand for massoia is high. Meanwhile, supply for the global market is still dominated by massoi from Papua. This condition leads to the over exploitation of massoi in nature. If this condition continues, massoi might be extinct in the future. Until now, the information about the potency of massoi in natural forests is not available yet. Therefore, studies that can depict the existence of massoi in natural forests are still needed. This study is needed to determine massoi's conservation strategies. This study aimed to determine the potency and distribution of massoi in the forest concession of PT. Yotefa Sarana Timber in Teluk Bintuni Regency and PT. Wanakayu Hasilindo in Kaimana Regency. This study applied line plot sampling method. The results showed that the potency of massoi in Teluk Bintuni Regency is higher than that of Kaimana Regency. The potency of massoi in Teluk Bintuni Regency was 1,593 individuals/ha, consisting of seedlings (1,500 individuals/ha) and stakes (93 individuals/ha). Potency of massoi in Kaimana Regency was just around 871 individuals/ha, comprising seedlings (750 individuals/ha), stakes (120 individuals/ha), and tree (1 individual/ha). Massoi at both pole and tree levels is alarming because of harvesting activities conducted by local people. The results also revealed that massoi grows scattered and rarely clustered. Massoi grows at an altitude of 50-500 masl (Teluk Bintuni Regency) and 400-900 masl (Kaimana Regency).
