Soil enhancement and nurse species
Artocarpus altilis has spreading surface roots that stabilize the soil on the steep hillsides in Micronesia. Its dense canopy provides shade and reduces temperature. The trunks can be used as trellises for vines and the regular shedding of its leaves provides mulch to the soil, thus improving growing conditions of intercropped species (Ragone, 2011).
Wildlife
Breadfruit trees host and feed many birds and bats. The pollen and the latex are collected by honeybees (Ragone, 2011).
