The islands are part of the Southern Indian Ocean Islands tundra ecoregion that includes several subantarctic islands. In this cold climate, plant life is mainly limited to grasses, lichens, and mosses. Low plant diversity reflects the islands'' isolation, small size, severe climate, the short, cool growing season and, for Heard Island, substantial permanent ice cover. The main environmental deter

Heard Island and McDonald Islands
Heard Island is the largest subantarctic island with no confirmed human-introduced plants. Areas available for plant colonisation on Heard Island are generally the result of retreating glaciers or new ice-free land created by lava flows.

Heard and McDonald Islands, Australia | SpringerLink
Five species of vascular plant occur on McDonald Islands and 11 on Heard Island . The isolation of the plant communities, combined with the increasing growth of habitat resulting from glacial retreat, makes Heard Island of significance for the study of plant colonization (UNEP/WCMC 2008).

Heard and McDonald Islands – Geotourism Guide
Heard Island and McDonald Islands are located in the Southern Ocean, approximately 1,700 km from the Antarctic continent and 4,100 km south-west of Perth. As the only volcanically active subantarctic islands they ''open a window into the earth'', thus providing the opportunity to observe ongoing geomorphic processes and glacial dynamics.

Is there a threat to Heard Island and the McDonald Islands?
Ongoing and accelerating climate change poses an increasing risk of fundamental alterations in biodiversity. Geological processes (primarily volcanism and glacial retreat) continue undisturbed. The overall assessment is that there is a low threat to the World Heritage values of Heard Island and the McDonald Islands if visitation remains low.
What is the significance of Heard Island & McDonald Islands?
Heard Island and the McDonald Islands, with the Kerguelen Islands, are exposed parts of the Kerguelen Plateau, possibly the largest submarine plateau on earth, and provide geochemical and isotopic insights into the formation of oceanic plateaux, mantle plume development and the separation of Australia, India and Africa from Antarctica.
Who manages the Heard & McDonald Islands?
The islands are administered under the Heard and McDonald Islands Act of 1953 and the Environment Protection and Management Ordinance of 1987 by the Antarctic Division of the national Department of Tourism, Arts & Environment (formerly the Department of the Arts, Sport, the Environment, Tourism & Territories, DASETT).
Why is Heard Island important?
The isolation of the plant communities, combined with the increasing growth of habitat resulting from glacial retreat, makes Heard Island of significance for the study of plant colonisation.
Why are Heard Island and McDonald Islands isolated?
However, the site’s isolation assists in reducing anthropogenic impacts upon the site’s values. Heard Island and McDonald Islands are located in the Southern Ocean, approximately 1,700 km from the Antarctic continent and 4,100 km south-west of Perth.
Where are Heard Island and McDonald Islands located?
The islands are a territory (Territory of Heard Island and McDonald Islands) of Australia administered from Hobart by the Australian Antarctic Division of the Australian Department of Climate Change, Energy, the Environment and Water.
