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]
