Habitat Changes on the Falkland Islands

Argentina – January 29th, 2013

The Falkland Islands (Islas Malvinas) are located in the South Atlantic Ocean on a projection of the Patagonian Shelf about 310 miles (500 kilometres) east of the Patagonian coastline and about 280 miles (450 kilometres) north-east of the southerly tip of Tierra del Fuego, Argentina. The Falklands, which have a total land area of 4,700 square miles (12,173 square kilometres) and a coastline estimated at 2,200 miles (3,500 km)[92] comprise two main islands, West Falkland and East Falkland and about 776 smaller islands. The two principal islands are 140 miles (220 km) from east to west and 87 miles (140 km) from north to south. They are heavily indented by sounds and fjords and have many natural harbours. The two main islands are separated by the Falkland Sound.

There is little long-term data on habitat changes, so the extent of human impact to the islands is unclear. Vegetation such as tussac grass, fachine, and native box have been heavily impacted by introduced grazing animals. Virtually the entire area of the islands is used as pasture for sheep. Rats and Grey foxes have been introduced and are having a detrimental impact on birds that nest on the shores, as are feral cats. Many breeding birds similarly only live on offshore islands, where introduced animals such as cats and rats are not found. There is also an introduced reindeer population, which was brought to the islands in 2001 for commercial purposes. Twenty two introduced plant species are thought to provide a significant threat to local flora.

Argentina – January 20th, 2013

Phytoplankton can be observed in the waters off the coast of Argentina. One bloom is present in and east of San Jorge Gulf, in the upper left quadrant. The other can be seen south of the Falkland Islands, known in Argentina as the Islas Malvinas, in the lower right quadrant.

Argentina – November 13th, 2012

The phytoplankton bloom that has been present off the Argentine coast since October (click here for previous images) continues to flourish, adding green and blue hues to the waters of the Atlantic. The image stretches from the Valdes Peninsula (top center) to the Falkland Islands, or Islas Malvinas (bottom right).

Sediments line the coast of Argentine Patagonia near Tierra del Fuego, on the left side of this image. Visible to the east are the Falkland Islands, known as the Islas Malvinas in Argentina. The archipelago is located over 250 nautical miles (460 km; 290 mi) east of the coast of mainland Argentina. It comprises East Falkland, West Falkland, and 776 lesser islands. Stanley, the capital and only city, is on East Falkland.

Falkland Islands - December 27th, 2011

This FAPAR image shows the vegetation index of East Falkland (known in Spanish as Isla Soledad), the largest of the Falkland Islands (Islas Malvinas), located about 250 nautical miles (290 mi; 460 km) from the coast of mainland Argentina.

The index is almost uniformly good (green), with some areas of low activity (yellow) near the center of the northern part of the island. The northern part of the island is hilly, and is crossed by a rugged range, the Wickham Heights, running east and west, and rising in some places to a height of just over 600 m (2,000 feet). The remainder of the island consists chiefly of low undulating ground, a mixture of pasture and morass, with many shallow freshwater tarns, and small streams running in the valleys.
