They mainly occur on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. A recent warming trend has increased germination, and thus number of seedlings and plants, also extending their range southward to cover larger areas; reports indicate a twenty-fivefold increase in their number.[2]
Deschampsia antarctica has been recorded by the Guinness Book of World Records as the southernmost flowering plant. In 1981, a specimen was found on the Antarctic Peninsula's Refuge Islands at a latitude of 68°21′S.[3][4]
Since 2009, both D. antarctica and C. quitensis have been spreading rapidly, which studies suggest has been the result of rising air temperatures and a reduction in the number of fur seals.[5]

Deschampsia antarctica Desvaux (hierba pilosa antártica o pasto antártico) es una de las dos plantas vasculares fanerógamas nativas de la Antártida, la otra es Colobanthus quitensis. Cada vez que hay pequeños aumentos de temperatura, más semillas germinan, creando un gran número de bancos de semillas y de plantas.[ru] Луговик антарктический
