It consists of all the land (predominantly offshore islands), including the Antarctic Peninsula, south of 60°S latitude and between longitudes 20°W and 80°W, an area of 1,709,400 km2. Although the area was explored much earlier by adventurous travellers and whalers, the territory was officially formed only in 1962. NW Antarctic Peninsula.

There are no native human inhabitants in BAT and the islands are used mainly to give access to the scientific research stations in the Antarctic – there are two year-round (Halley and Rothera) and one summer-only (Signy) UK research stations here. Many other countries also have research stations in this region, as the Southern Ocean offers unique opportunities for understanding evolution in marine systems.

This legislation covers also environmental monitoring and impact assessment, waste management, oil spills and protected areas and species. The British Antarctic Territory Strategy sets the main objectives and funding priorities for the territory and is reviewed annually and updated as appropriate.

Copyright: Dr Mike Pienkowski Most of the landmass in the Antarctica is permanently covered with ice. However, life is still present in the 1% of the region that is ice- and snow-free. In these areas, there are large numbers of seals, penguins and birds, as well as a variety of mosses, liverworts, lichens and fungi. According to the British Antarctic Survey, there are, in total, around 100 species of mosses, 25 species of liverworts, and 300 to 400 species of lichens in the Antarctica. They can tolerate low temperatures and dehydration, being specially adapted to surviving in extreme environments. Trees and shrubs do not grow in these conditions. There are only two species of flowering plants that occur in Antarctica, the Antarctic hair grass and Antarctic pearlwort. These arise along the warmer parts of the Antarctica Peninsula and in the South Orkney Islands and the South Shetland Islands. Human activities such as whale and seal hunts and the more recent waves of tourists unintentionally carried exotic species into these regions. Invasive species are the biggest threat to the native flora of Antarctica. The terrestrial fauna of the Antarctic continent is sparse; no higher insects are present, while micro-arthropods are restricted to limited areas of vegetation and (vertebrate) nutrient enrichment. In the most extreme continental cold deserts, simple food webs consist of as few as 1 – 3 nematode species, only one of which may be predatory. These cold desert soils are faunistically the least diverse habitats on Earth. Chinstrap penguin Pygoscelis antarcticus pair at nest site.

This includes whales, seals and very large numbers of birds, especially petrels and penguins, inhabiting the islands and coastal areas of the Peninsula. Adélie and emperor penguins, and Antarctic snow petrels, all breed on the continent itself, and chinstrap, gentoo and macaroni penguins breed on the northern tip of the Antarctic Peninsula, where conditions are less harsh. Adélie penguins dive into the sea.

Annual meetings of the Treaty and CCAMLR provide a forum for monitoring environmental activities and fishing. Port Lockroy station.

It cares for and conserves historic buildings and artefacts in Antarctica, including their flagship historical site, Port Lockroy. For more than a century, Port Lockroy has been a home for explorers, whalers, scientists, and sailors who have made vital contributions to Antarctic history and the harbour, at the meeting point of 3 seaways has become the most popular visitor destination in Antarctica today, complete with museum, shop and post office.
