On this World Environment Day we focus on Marion Island as the #generationrestoration highlights the importance of the Mouse-Free Marion Project
Marion Island and Prince Edward Island, collectively known as the Prince Edward Islands, are tiny specks of land in the Southern Ocean, the huge body of water that encircles the Antarctic Continent. Marion Island is the larger of the two islands, with an area of just under 300 square kilometres, whereas Prince Edward Island is considerably smaller – a mere 45 square kilometres. With a summit of 1 230 metres Marion Island is also much higher than the 672-metre high Prince Edward Island. The two islands are close neighbours, with only 19 kilometres of relatively shallow water separating them.
The Prince Edward Islands, together with the other islands within the Southern Ocean, form part of a complex and productive ecosystem that has far-reaching influences. In turn the ocean dominates many aspects of the islands, from the way the vegetation grows to climate and geomorphology. The islands rose above the surface of the ocean after a prolonged period of underwater volcanic activity and the rocks and many of the landscapes reflect these tumultuous beginnings. From the jagged, almost surreal expanse of the black lava fields, to the many red scoria cones that dot the landscape, these volcanic origins are responsible for some of the most striking natural features of the islands. Despite the fact that today, researchers and managers visit them every year the islands still remain one of the wildest places on earth.

National Environment Month is celebrated in June, with the South African government and captains of industry leading the way by stimulating awareness on environmental issues and challenging all to become agents for change. June is Environment Month under the theme “Think, Eat, Save and reduce your foodprint”. we celebrate our Antarctic region environment.
The theme for World Environment Day and National Environment Month rests on three pillars. According to the United Nations Food and Agriculture Organisation (FAO), every year 1.3 billion tons of food is wasted. Therefore, communities are encouraged to “Think” before discarding food off as waste. The second pillar, “Eat” encourages consuming food in such a way that the environmental impact is reduced. Third pillar encourages communities to make wise decisions about discarding food and “Save” as far as possible.
World Environment Day 2024 focuses on land restoration, halting desertification and building drought resilience under the slogan “Our land. Our future. We are #GenerationRestoration.” We cannot turn back time, but we can grow forests, revive water sources, and bring back soils. We are the generation that can make peace with land.
Environmental events celebrated during National Environment Month include:
- 5-Jun World Environment Day
- 8-Jun World Oceans Day
- 19-Jun World Albatross day
- 21-Jun International Day of the Celebration of the Solstice

MINISTER CREECY LAUNCHES THE 3RD NATIONAL STATUS OF BIOLOGICAL INVASIONS AND THEIR MANAGEMENT IN SOUTH AFRICA
Full release available on Department of Forestry Fisheries nd the Environment website
“We must continue investing in research and innovation, supporting studies that enhance our understanding of invasive species dynamics to improve management strategies. The 3rd National Status report on Biological Invasions serves as a clarion call for action reminding us of the urgency of the situation and the imperative to act decisively,”
“Addressing the challenges posed by biological invasions requires a coordinated and collaborative effort. No single entity can tackle this issue alone. Government, academics, civil society organisations and communities must come together, pooling their knowledge, resources and expertise to develop effective prevention, early detection and control strategies,” said Minister Creecy.
Thirdly, invasive species are devastating the unique and sensitive biodiversity of the Prince Edward Islands. For the first time, this report provides a separate assessment of the status of biological invasions and their management on the Prince Edward Islands. Although these islands are part of South Africa, their remote location and unique biodiversity warrant a separate assessment. Findings highlight the devastating impact of the house mouse, which is alien to the Marion Island. The mice feed on plants, and small animals including endangered seabirds. A bold plan to eradicate mice from the island has been developed and is due to be implemented in 2027. The eradication of mice from Marion Island is essential if its unique biodiversity is to be preserved.

A session has been included in the 6th SANAP symposium to include the Prince Edward Island scientific survey members as they were arriving late on the 29 November. As a cross discipline on Data Management and the Summer Survey Participants. Christel Hansen chaired the session ‘Data and frameworks in the support of polar research’.

The last session within the Marine and Antarctic Research Strategy research theme : : Ecosystems, biodiversity and biodiscovery was chaired by Pierre Pistorius of the Marine Apex Predator Research Unit (MAPRU) at Nelson Mandela University. To kick off the session, the Mouse-Free Marion (MFM) Project’s Assistant Project Manager, Sue Tonin, gave a plenary lecture. This was followed by more presentations on ornithology research. (Above: group photo of MAPRU with Sue Tonin. Left: Pierre Pistorius. Right: Sue Tonin)

Maelle Connan and Stefan Schoombie were part of the Prince Edward Island Scientific Expedition and were able to join the session. Stefan’s presentation was given in the Summer Survey session later on in the day. Support for Sue’s plenary came from Robyn Adams, MFM Communications Officer and Project Assistant, and John Cooper, MFM News Correspondent.

Prof Werner Nel chaired the session on earth system Observations under the title: “Antarctic and sub-Antarctic Earth Science”. The session opened with a talk by Geoff Grantham of University of Johannesburg and Werner then introduced research Landscape and climate interactions in the sub-Antarctic. The session was in the format of a panel and roundtable discussion. (Above group photo of Landscape research in mountain and polar environments)
