The Norfolk Island group provides an important link between tropical and temperate oceanic island environments. Their isolation and climate make them important habitats for breeding areas for migratory seabirds, and as important refuges for endemic animals and plants.

The island is home to around 200 native plants, including more than 40 which are only found here.

Before European settlement subtropical rainforest covered almost the entire island. Norfolk Island National Park and Botanic Garden now contain most of the island's remaining natural areas, making them a vital refuge for conserving the island's plants and animals.

The magnificent Norfolk Island pine is one of Norfolk's best known symbols - it is common across the island and can grow as tall as 60 metres. Cultivated around the world as an ornamental tree, its wood is used for construction, wood turning and crafts and the seeds are a popular food for the endangered green parrot.
