<p><i>Alstonia angustiloba</i> thrives in a variety of environments, including primary and secondary forests, swamps, hills, and various soil types up to 800 meters in altitude. It typically grows as a mid-canopy tree in mixed dipterocarp forests on low hills and undulating terrain, as well as in freshwater swamp forests. The species is commonly found in abundance in secondary forests and exhibits tolerance to a wide range of soil conditions, from waterlogged to drier environments. Its flowers attract insects such as butterflies and bees, which play a key role in pollination. However, the tree's bark and leaves exude a milky latex that can be irritating, and its copious pollen during blooming may trigger nasal allergies. Propagation is primarily through seeds, which are easy to germinate with a high success rate. The seeds are dispersed by wind due to their lightweight nature and the presence of coma at both ends, making collection challenging.</p>
