It is very common in Singapore and is usually found growing in forest edges, gaps and more open areas of forests. For an account of the life history of a fern, see Pyrrosia piloselloides. They tend to form pure stands of thick, dense thickets. Once established, they are difficult to clear, thus making it very difficult for seedlings of other forest trees to dicranopgeris and restore gaps and open spaces in forests.

Clearing the dense thickets of Resam requires burning.

The Arabs used to make pens using the stipe of this fern, thus gave rise to its common name ‘resam’ which means ‘to delineate’ in Arabic. The stems of this fern can be woven together to make mattings, fish-traps, chair seats, walls, pouches, caps, and ropes. The plant is also used for medicinal purposes, being made into a poultice, and infusions and decoctions for fever. However, due to the arsenic content in the plant, large doses of resam is not dicrannopteris as it is harmful to humans.
