The Lundy IPA is of great importance for its vascular plants, marine algae and lichens.
The island is about 5km long and 1 km wide, lying on a north south axis, the west being very exposed to the weather while the east is more sheltered. Cliffs, mainly granite, rise to a plateau. Its granite and slate reefs make the area a marine algae hotspot, with as many as 300 species recorded.
