Dicranopteris linearis - Resam
Dicranopteris linearis is a species of fern known as Resam ( in Malay ) or Old World forked fern, besides many other common names. It is one of the most widely distributed ferns of the Old World tropics.
It grows easily on poorly drained, nutrient-poor soils and in disturbed habitat and steep slopes with open-canopy. Thus making it a pioneer species on primary successional sites such as landslides, road-cuts, abandoned logging decks, post-agricultural sites, degraded forest lands etc. Once established, D. linearis persist for a long time but is eventually shaded out by overtopping trees.
This fern spread via rhizome, capable to form thickets 3 meters thick or more. The stems are very slow to decompose, thus may poses fire hazard during dry season.
