Signatories to the Antarctic Treaty System's Environmental Protocol are committed to preventing incursions of non-native species into Antarctica, but systematic surveillance is rare. Environmental DNA (eDNA)…
Atmospheric gravity waves play an important role in transporting energy and momentum between atmospheric spheres and drive circulations that affect key processes such as formation of the ozone hole and the cold summer polar mesosphere.
Fuel spills have occurred in Antarctic and sub-Antarctic regions, and comprehensive remediation strategies have recently been established to clean-up fuel spills at Australia’s Casey Station and Macquarie Island. However…
Poa annua is the most widespread alien species in the sub-Antarctic, occurring on all major island groups and is invasive and spreading on the Antarctic Peninsula. P. annua colonises areas disturbed by human activity, seal wallows, penguin rookeries and glacial moraines.
In response to several fuel spills on sub-Antarctic Macquarie Island associated with research station operations, the Australian Antarctic Division has initiated a 5-10 year plan to remediate the island’s contaminated sites using low cost in-situ techniques.
Poa annua is a non-native grass found in Antarctica and the sub-Antarctic. It has a restricted distribution on Heard Island but is common and widespread on Macquarie Island, both World Heritage Areas.
The sub-Antarctic islands are some of the least inhabited and most protected ecosystems in the world. Due to their isolation and low human visitation they have escaped the worst effects of alien plant invasion.

The Southern Ocean islands are some of the most isolated landmasses in the world. Few of the islands support permanent human settlements or land based industries and as such they remain as some of the most uninvaded landscapes globally.
