Distribution, importance and conservation status

Generally scattered all over the Philippines particularly in the Balabac group of islands, the kalantas tree can be found in the hills of a forest situated in low to medium altitudes. The wood of the tree is used for making boxes, furniture or plywood. Kalantas has been categorized by the International Union for Conservation of Nature as Data Deficient but it was reported that kalantas is exhausted due to logging and kaingin. Reforestation efforts have been done in the Philippines and the kalantas tree is included in these efforts. One of the efforts were done by the Philippine Department of Environment and Natural Resources during the term of then President Gloria Macapagal-Arroyo where the president herself planted a seedling of a kalantas tree, which is the favored tree promoted by the president.
