Other uses

In local construction, raffia fibres are used for ropes, with branches and leaves providing sticks and supporting beams, and various roof coverings. The people of Ogba kingdom in Rivers State and other southern Nigerians use raffia palm fronds as fishing poles. The frond is usually cut from a young palm tree. The leaves are removed and the stake is dried, which becomes very light, and the hook is attached to a line, which is tied to the stake, making it a fishing pole. The raffia palm is important in societies such as that of the Province of
