Justification: The species is found in two locations, namely Bukidnon and Misamis Occidental (MindanaoIsland). The population is confined to secondary and primary forest at lower elevations. Both locations are protected areas, however, part of Mt.Malindang Range is now being logged by indigenous and local people. In Bukidnon, the population of A. sanderiana was found growing in the Almaciga Reforestation Project area. This place is frequented by local tourists who visit the waterfalls in the area.
