Fauna and flora of the Malvinas Islands

The Malvinas Islands (Falklands) host a unique ecosystem shaped by their cold, windy climate and isolation. The fauna is dominated by marine mammals and seabirds, while the flora consists mainly of grasses, shrubs, and peat bog vegetation, with no native trees.

Flora of the Malvinas Islands

• Grasslands and Shrubs: The islands are largely covered by tussac grass (Festuca flabellata), which can grow up to 2 meters tall and provides shelter for birds and sea lions.

• Peat Bogs: Extensive peatlands support mosses and small herbaceous plants.

• Heathlands: Areas with dwarf shrubs and hardy plants adapted to poor soils and strong winds.

• Endemic Plants: Species such as Malvinas Daisy (Perezia recurvata) and Malvinas Violet (Viola maculata) are unique to the islands.

• Absence of Native Trees: No native arboreal vegetation exists today, though fossil records show ancient cypress and araucaria forests.

Fauna of the Malvinas Islands

Marine Mammals

• Seals and Sea Lions: Southern sea lions, elephant seals, and fur seals are common along the coasts.

• Cetaceans: Orcas, dolphins, and several whale species migrate through surrounding waters.

Birds

• Penguins: Five species breed here: King, Gentoo, Rockhopper, Macaroni, and Magellanic penguins.

• Seabirds: Albatrosses, petrels, cormorants, and skuas thrive in the nutrient-rich waters.

• Land Birds: The Falkland steamer duck (flightless), upland goose, and the endemic Cobb’s wren are notable.

Invertebrates

• Endemic Beetles: Several species of ground beetles and weevils are unique to the islands, such as Malvinius compressiventris.

Conservation Notes

• Fragile Ecosystem: The harsh climate limits biodiversity, making species highly specialized and vulnerable.

• Threats: Introduced species (rats, cats) have impacted native bird populations.

• Protection Efforts: Conservation programs focus on seabird colonies and restoring tussac grass habitats.
