The characteristics of the Marine National Park are the tropical evergreen rainforest, the vast coral reef systems that protect a wide range of aquatic ecosystems, and significant biodiversity in this area.

[2] Lampi Island Marine National Park is generally flat, rising steeply from the sea level to 270 m (890 ft) and includes a few beaches and sand-covered inlets.

Lowland forests harbour Dipterocarpus alatus, epiphytes including lianas, stands of Casuarina equisetifolia, Dillenia and Calophyllum, wild orchids and ferns.

Seagrass present around the eastern part of the island comprises Thalassianthus hemprichi, Cymodocea rotundata, Halodule uninervis, H. pinifolia and dugong grass (Halophila ovalis).

This is especially true for individuals who travel from outside the island to hunt and sell mouse deer, pangolins, wild pigs, and common water monitors to fishing boats or to inland markets.
