The Antarctic flora is a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana, and is now found on several separate areas of the Southern Hemisphere, including southern South America, New Zealand, Australia and Tasmania, and New Caledonia.
The woody plants of the Antarctic flora include conifers in the families Podocarpaceae, Araucariaceae and the subfamily Callitroideae of Cupressaceae, and angiosperms such as the protea family Proteaceae, southern beech (Nothofagus), Winter's Bark (Drimys) and fuchsia (Fuchsia).

The volcanic origin and remote location of the islands meant that the lslands' flora and fauna had to reach the archipelago from far across the sea; as a result, the island has relatively few plants and very few animals.
The closest relatives of the archipelago's plants and animals are found in the Temperate broadleaf and mixed forests ecoregions of southern South America, including the Valdivian temperate rain forests, Magellanic subpolar forests, and Desventuradas Islands.
Many plants are characteristic of the Antarctic flora, and are related to plants found in southern South America, New Zealand and Australia.

Impacts from Antarctic development would be easier to detect due to the relatively pristine nature of the surrounding environment; however, it will be difficult and expensive to implement effective monitoring programs because of Antarctica's remoteness and adverse working conditions.
Impacts on terrestrial flora and microfauna in the immediate vicinity of these mining and ore process ing activities should probably be considered permanent; total natural recovery of adjacent areas would require many decades to a few centuries.

The majority of the Antarctic continent is covered by permanent ice and snow leaving less than 1% available for colonization by plants.
Most of this ice and snow-free land is found along the Antarctic Peninsula, its associated islands and in coastal regions around the edge of the rest of the Antarctic continent.
South Georgia, for example, has a vascular flora of 26 indigenous species, with a further 15 alien species which are well-established, and in some cases spreading, and a number of other alien species which are managing to survive close to the former whaling stations.

Article IX 1(f) of the Antarctic Treaty cites 'preservation and conservation of living resources in Antarctica' as one of the matters upon which recommendations might be made to Consultative governments in furtherance of the principles and purposes of the Treaty.
At the first Antarctic Treaty Consultative Meeting in 1961 it was agreed (Recommendation I-VIII) to consider the matter further and, as an interim measure, to recommend that the general rules SCAR had developed should be issued to Antarctic exped itions.

The true Antarctic animals, ones that live on the continent all year round, are in fact microscopic, and include several species of nematode worms.
As well as the intense cold during the winter, in the spring their habitat is often saturated with water and the nematode experiences regular potentially lethal cycles of freezing and thawing.
Antarctic birds and mammals, for example, can generate their own heat.

 Understanding CCAMLR's Approach to Management
The exploitation of Antarctic marine living resources has been characterised by intense and sporadic pulses, in many cases resulting in the severe depletion of harvested stocks (as was the case for fur and elephant seals in the 19th century, and whales and finfish in the 20th century) (see section 1.2).
In the mid-1970s, it was realised that the conservation of krill was fundamental to the maintenance of the Antarctic marine ecosystem (Figure 1) and vital to the recovery of depleted whale populations.
The Convention applies to all marine living resources (except seals south of 60?S and whales in general) inside an area whose northern boundary is roughly delineated by the mean position of the Antarctic Polar Front and thus follows the physical and biological boundaries of the Antarctic (Figure 8).

Malesia is a biogeographical region straddling the boundary of the Indomalaya and Australasia ecozones.
Malesia was first identified as a floristic province that included the Malay Peninsula, Indonesia, the Philippines and New Guinea, based on a shared tropical flora derived mostly from Asia but also with numerous elements of the Antarctic flora, including many species in the southern conifer families Podocarpaceae and Araucariaceae.
The Philippines were also never connected to Asia, and have a largely Asian-derived flora, with some Australasian elements, and a distinct mammalian fauna.
