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.

Threats [top]

Major Threat(s): Agricultural expansion (kaingin) and associated increased exploitation are the main threats to A. sanderiana at Mt.MalindangRange.  In Bukidnon, the population is at risk from recreational activities; the area is often visited by local tourists due to the presence of water falls and swimming pools. Plants are collected for ornamental and medicinal use.

Conservation Actions [top]

Conservation Actions: Both locations were declared as protected areas but the implementation is very poor.
