Nepenthes Naga - Ecology

Ecology

Nepenthes naga is known only from a small population in the Barisan Mountains of North Sumatra. It grows epiphytically in mossy montane forest and has an altitudinal distribution of 1500–2000 m above sea level. The vegetation in this habitat is dominated by Fagaceae and Gleicheniaceae, as well as various montane shrubs.

Nepenthes naga occurs in an unprotected area. Plantations of the Pará rubber tree (Hevea brasiliensis) at the foot of the hill inhabited by N. naga pose a threat to this species. Population decline is also attributed to plant collectors, who have removed a number of plants and collect seeds in such numbers that few are left to germinate naturally.

The species has no known natural hybrids.
