Understanding tropical forest characteristics, including forest derivative products such as agarwood, is pivotal. This study focused on perceiving an ideal habitat of the lowland tropical forest ecosystem of West Papua for agarwood-producing tree species. In further, this study identified a close association of biotic and abiotic characteristics to underpin agarwood-producing tree growth. Six sites in three different locations were established to ascertain forest composition and the associated insects. Soil samples were collected to analyze their physical and chemical properties using the Kjeldahl, the Walky and Black, and Atomic Absorption Spectrophotometry (AAS). In addition, temperature, relative humidity, and light intensity were measured. The results noticed two agarwood producing species, Gyrinops caudate and Aquilaria sp., found at an altitude of 400−402 masl in Manokwari, 200−300 masl in Teluk Wondama, and 167.7 masl in Teluk Bintuni. There were no significant differences in temperature, relative humidity, and light intensity. The soil cation exchange capacity was moderate in Manokwari, but it was low in Teluk Wondama and Teluk Bintuni. Total C-organic content in three research sites was classified as high. However, total N content in the three research sites was in the moderate category. The ideal habitat for agarwood in the West Papua forest is from the lowlands to the highlands. Environmental conditions that support the growth of agarwood are moderate temperature, high humidity, and moderate light intensity. Soil fertility also affected the natural growth of agarwood trees.
