Cape York Peninsula has a range of intact tropical rainforests, tropical and subtropical grasslands, savannahs, and shrublands, tropical savannahs, heath lands, wetlands, wild rivers and mangrove swamps. These are home to about 3300 species of flowering plants. Almost all of the Cape York Peninsula (99.6%) still has its native vegetation. Cape York Peninsula also contains one of the highest rates of endemism in Australia, with more than 260 endemic plant species found so far. Because of this, parts of the Peninsula have been noted for their very high wilderness quality. The plants of the peninsula includes original Gondwanan species, plants that have developed since the breakup of Gondwana and species from Indo-Malaya and from across the Torres Strait in New Guinea. Most variety is in the rainforest areas. Most of the Cape York Peninsula is drier than New Guinea which stops the rainforest plants of that island from moving across to Australia.
