Cape York Peninsula supports a complex mosaic of intact tropical rainforests, tropical and subtropical grasslands, savannahs, shrublands, heath lands, wetlands, wild rivers and mangrove swamps. The savannah woodlands consist typically of a tall dense grass layer and varying densities of trees, predominantly eucalypt of which the most common is Darwin stringybark ("Eucalyptus tetrodonta"). These various habitats are home to about 3300 species of flowering plants and almost the entire area of Cape York Peninsula (99.6%) still retains its native vegetation and is little fragmented. Although abundant and fully functioning on the peninsula, tropical savannahs are now rare and highly degraded in other parts of the world. Cape York Peninsula also contains one of the highest rates of endemism in Australia, with more than 260 endemic plant species found so far. Therefore, parts of the peninsula have been noted for their exceptionally high wilderness quality. The flora of the peninsula includes original Gondwanan species, plants that have emerged since the breakup of Gondwana and species from Indomalaya and from across the Torres Strait in New Guinea with the most variety being found in the rainforest areas. Most of the Cape York Peninsula is drier than nearby New Guinea which limits the rainforest plants of that island from migrating across to Australia. Tropical rainforests cover an area of , or 5.6 percent of the total land area of Cape York Peninsula. Rainforests depend on some level of rainfall throughout the long dry season, climatic conditions that are mostly found on the eastern slopes of the peninsula's coastal ranges. Being almost exclusively untouched, old-growth forests and supporting a disproportionately high biodiversity including flora of Gondwanan and New Guinean origin, the rainforests are of high conservation significance.
