Diversity of Aquatic and Marsh plants in Western Sarawak

Sarawak is a Malaysian state on the island of Borneo. Malaysia has an estimated 15,000 vascular plant species, with approximately 8,300 in Peninsular Malaysia and over 12,000 in Sabah and Sarawak, including aquatic and marsh plants that are critical to the biological balance of the wetlands there.
