Every year on February 2nd, the world comes together to celebrate World Wetlands Day, marking the anniversary of the Ramsar Convention on Wetlands, signed in 1971 in Ramsar, Iran. This global observance highlights the vital role wetlands play in sustaining biodiversity, mitigating climate change, and supporting life on Earth.
In 2025, as we reflect on the importance of wetlands, our focus turns to the remote and ecologically significant Prince Edward and Marion Islands—South Africa’s sub-Antarctic treasures and key players in global wetland conservation. South Africa, a proud signatory, has committed to preserving its rich and diverse wetland ecosystems, including the critically important wetlands of the Prince Edward Islands.
Located in the Southern Ocean, the Prince Edward and Marion Islands form a remote, uninhabited archipelago under South African jurisdiction. These islands are not only home to breathtaking volcanic landscapes but also to some of the most ecologically valuable wetland systems on the planet.
The islands’ peat bogs, freshwater lakes, and coastal wetlands serve as vital habitats for a variety of endemic and migratory species. They play a crucial role in supporting breeding colonies of seabirds, including albatrosses and petrels, as well as the charismatic king penguins and fur seals that depend on these ecosystems for survival.
Wetlands in these remote regions are particularly sensitive to environmental changes, including climate change and human activity. Rising temperatures and shifting oceanic currents threaten the delicate balance of these ecosystems, impacting their ability to regulate water cycles, store carbon, and provide shelter for wildlife.
By recognizing the importance of these wetlands and strengthening conservation measures, South Africa reaffirms its commitment to preserving its Ramsar-designated sites and ensuring the long-term health of these fragile ecosystems.
While Prince Edward and Marion Islands remain largely untouched by direct human impact, global efforts to mitigate climate change, reduce pollution, and support marine protected areas are essential in safeguarding these wetlands.
As we commemorate World Wetlands Day 2025, let us take inspiration from the wild and untouched beauty of Prince Edward and Marion Islands. These remarkable landscapes remind us of the interconnectedness of our planet’s ecosystems and the urgent need to protect them for future generations.
