Ground-breaking project first step on path to restore Norfolk Island

There are about 180 native plant species on Norfolk Island, of which about a quarter are found nowhere else on the planet and 46 are listed as threatened.

Another 430 plant species have been introduced to the island, some have become environmental weeds that have pushed out native species. Past land management has also pushed many native plant species into small, fragmented pockets of remnant vegetation.

Tara Patel is Senior Environmental Officer at Norfolk Island Regional Council and works closely with the local community replanting and restoring native habitat.

“Norfolk Island’s plant communities have evolved in relative isolation over 2.5 to 3 million years, creating a landscape rich in native plant and animal species,” said Ms Patel.

“The island is home to the world famous Norfolk Island Pine and a substantial number of our native species are found nowhere else on Earth, including 43 plants and 15 bird species, including the critically endangered Norfolk Island green parrot.

“Norfolk Island has a fascinating human history and an incredibly rich natural heritage, but past land management and the introduction of non-native species has put huge pressures on our natural landscape. These maps provide a vital resource for planning effective conservation, restoration and management of the remaining native vegetation.”

Dr Ray Nias, director at nature conservation charity TierraMar, says an 1804 drawing by Ferdinand Bauer gives a very clear indication of what Norfolk Island looked like 200 years ago.

“The illustration by Ferdinand Bauer shows Norfolk Island with dense, thick forest cover stretching as far as the eye can see,” Dr Nias said.

“Hardwood forest covered most of the island’s hinterland and pines could be found in coastal areas and along mountain ridges.

“There has been a real push by the Norfolk Island community recently to repair and restore areas that are suffering from weeds and past land management practices.

“These new maps will play a vital role in helping the community restore our rich natural heritage and secure a future for many of our threatened native plants and animals.”

The mapping is based on extensive survey work conducted by Naomi Christian, a native Norf’k Islander, and recognised plant ecologist Dr Kevin Mills. This work was completed in 2020. Funding was provided through the Eldon and Anne Foote Trust, administered by the Lord Mayor’s Charitable Foundation, the Commonwealth Department of Infrastructure, Transport, Regional Development and Communications, and supported by the Norfolk Island Regional Council.


  • The new maps describe and map 14 native plant communities across the island and will help land managers protect and restore habitat for threatened species and other wildlife of Norfolk Island.
  • Some 3 million years ago a volcano erupted in the southern Pacific Ocean on a ridge of the largely submerged continent of Zealandia. The lava that flowed from multiple eruptions over the next 700,000 or so years built up into a mountain that emerged from the sea. Thus was born land far from any other land mass, the Norfolk Island group.
  • A native plant community is a distinct association of native plants that grow together, as determined by environmental factors including moisture availability, maritime influence, aspect, prevailing winds and soil characteristics.
  • The 14 distinct native plant communities on Norfolk Island include forests, swamps, shrublands and grasslands.
  • The Invasive Species Council campaigns for stronger laws, policies and programs to protect Australia’s native plants and animals from environmental weeds, feral animals and other invaders.

    TierraMar works with communities, businesses and governments to shift the paradigm on how conservation is done, so that people and nature thrive.
