Managing invasive plants on sub-Antarctic Macquarie Island
The Antarctic region is one of the most inhospitable frontiers on earth for weed invasion. On Australia's world heritage sub-Antarctic Macquarie Island only three species of invasive weeds are well established (Poa annua L., Stellaria media (L.) Vill. and Cerastium fontanum Baumg.), although is...

The Antarctic region is one of the most inhospitable frontiers on earth for weed invasion. On Australia's world heritage sub-Antarctic Macquarie Island only three species of invasive weeds are well established (Poa annua L., Stellaria media (L.)
