The explosion supposedly occurred four years before the 1891 visit of a Jesuit priest, who reported that he could not examine the volcano more closely because of strong solfataric activity.

Reforestation efforts on the bare areas, both in tree-planting drives and by Central Mindanao University personnel, have established temporary forests of Acacia mangium and conifers.

[3] Three species of pteridophytes are locally threatened: Marsilea crenata ("apat-apat"), Ceratopteris thalictroides ("pakung-sungay"), and Lycopodiella cernua (clubmoss).

Currently its slopes has been the target of extensive reforestation efforts partly paid for by the establishment of toll gates to hikers intending to go up the mountain.
