The Gough Island Restoration Programme
Situated in the South Atlantic Ocean, positioned equidistantly between South Africa and South America, lies a highly significant breeding ground for seabirds known as Gough Island. This remote island serves as the breeding habitat for 24 distinct avian species, many of which are found nowhere else on the planet. Regrettably, the avian inhabitants now share their home with an invasive species, specifically the house mouse. These non-native mice, introduced to the island by human activity, are causing severe harm to the island’s native wildlife, including plants and animals that have thrived there for millennia. The mice’s voracious appetite leads to the consumption of over two million seabird eggs and chicks annually, driving certain species perilously close to extinction.
In an effort to safeguard the birds, the Gough Island Restoration Programme was launched with the aim of eradicating the mice. In 2021, the Gough Island Restoration Programme attempted to eradicate mice from the island in one of the most challenging and logistically complex island eradications ever ventured.
Although the endeavor did not achieve complete success, it significantly reduced the mouse population, providing a respite for the birds. During this period, the avian inhabitants managed to successfully raise numerous chicks.
Scientists continue to monitor the birds and gather valuable information that will hopefully aid in future endeavors to eliminate the mice entirely. Part of this takeover and the overwintering field team’s work programme will relate to follow-up activities to further underpin efforts to restore Gough Island.

More about the work on the island for this takeover:
“During takeover our team is carrying out a census of Tristan Albatrosses and Southern Giant Petrels across the whole island, the so-called round island survey. At this time of year, the Southern Giant Petrels are starting to breed while the Tristan Albatross chicks are about to fledge. The number of fledged Albatross chicks will then be compared to numbers of breeding pairs that were counted at the beginning of the year and so breeding success for this Critically Endangered bird can be calculated (more than 99% of the global population breed exclusively on Gough Island). The round island survey also provides the team with the opportunity to monitor the abundance and distribution of the two landbird species, the Gough Bunting and the Gough moorhen.
This takeover the team will also be taking some soil samples from the upland parts of the island. This is to help monitor the ecosystem in the wake of the mouse eradication attempt”.

On 19th of June, the world comes together to celebrate World Albatross Day, an annual event dedicated to raising awareness about these magnificent seabirds and the conservation challenges they face. World Albatross Day serves as a crucial platform to educate and inspire action to protect these iconic ocean wanderers. With their graceful flight and important ecological role, albatrosses deserve our attention and concerted efforts for their survival.
South Africa is a long-standing Party to the International Agreement on the Conservation of Albatrosses and Petrels (ACAP). The agreement was brought into existence on 1 February 2004. The day also falls on the date of the signing of the Agreement 22 years ago. ACAP has chosen the theme “Plastic Pollution” to mark the fourth World Albatross Day, to be celebrated on 19 June 2023. This follows the inaugural theme “Eradicating Island Pests” in 2020, “Ensuring Albatross-friendly Fisheries” in 2021, and “Climate Change” last year in 2022.
Albatrosses close to home
Multiple species of albatross are found across the Southern Ocean. This includes Antarctic, sub-Antarctic and subtropical waters. These albatrosses breed on sub-Antarctic and Antarctic islands including South Africa’s sub-Antarctic Marion Island. Marion Island holds significant breeding populations of four albatross species – the Wandering Diomedea exulans, Grey-headed, Light-mantled Phoebetria palpebrata and Sooty Phoebetria fusca. In addition to this, two other species of albatrosses have been seen ashore on Marion Island – Black-browed and Indian Yellow-nosed Thalassarche carteri. To read more about the “other” two species of albatrosses recorded from Marion Island as uncovered by one of our researchers Kim Stevens, click here.
The Challenges Facing Albatrosses
Albatrosses face a range of challenges that threaten their survival. One of the most pressing issues is longline fishing, where albatrosses can become accidentally caught on fishing hooks, leading to injury or death. Pollution, habitat destruction, climate change, and invasive species on breeding islands also pose significant risks to their populations. World Albatross Day sheds light on these challenges and promotes measures to mitigate their impact. The pressing threats to Albatrosses in the Southern Ocean include invasive species on breeding islands, most notably, the house mice on Marion Island. Introduced to Marion Island by sealers in the early 19th century, the house mice have been inflicting devastating impacts on the ecology of the island, including killing its native seabirds.
Conservation Efforts and Awareness
The Mouse-Free Marion Project is a registered non-profit company in South Africa, established to eradicate the invasive albatross-killing mice on Marion Island. The project was initiated by BirdLife South Africa and the South African Department of Forestry, Fisheries and the Environment (DFFE). Upon successful completion, the project will restore the critical breeding habitat of over two million seabirds, many globally threatened, and improve the island’s resilience to a warming climate. For more information or to support the project please visit mousefreemarion.org.
May 2023: Barbara Creecy, Minister of Forestry, Fisheries, Forestry and the Environment, confirms government support for the Mouse-Free Marion Project in her budget speech.
What can you do?
In keeping with this year’s theme for World Albatross Day “Plastic Pollution”, as an individual you can participate by reducing plastic pollution, organising or joining local beach cleanups, where you can help remove litter and prevent it from reaching the oceans, including minimising the use of single-use plastics. Education plays a vital role in driving positive change for albatross conservation. Increase your understanding of albatross biology, their unique adaptations, the threats they face, and the ecological importance they hold in marine ecosystems by reading some of these selected publications here. By raising awareness and fostering partnerships, we can work collectively to safeguard albatross populations and their habitats.
Let us unite in our efforts to protect these majestic ocean wanderers and ensure a future where albatrosses continue to grace our oceans for generations to come.

The Mouse-Free Marion Project is a partnership between the Department of Forestry Fisheries and the Environment (DFFE) and BirdLife South Africa, working towards an operation to eradicate invasive mice from Marion Island.
The mice, which were introduced accidentally some 200 years ago, have caused great harm to the ecology of Marion Island. They feed on indigenous invertebrates, damage vegetation, and have more recently started eating seabird chicks. As a result, the mice are considered to be a major pest to the island. If they are not removed, the ecosystem of the island will continue to deteriorate, and they will likely cause most of the seabirds on the island to become locally extinct. These seabirds will be lost to the island forever.
In order to monitor how the island recovers after the mice have been removed, we are collecting data on aspects of the island that we expect to improve once the mice are gone. These include the vegetation and invertebrates. Colleagues working on other projects are collecting similar data on seabirds.
The reason why it is important to collect this data before the eradication operation is so that we can compare and monitor how the island changes (improves) as a result of the eradication operation – comparing the island’s vegetation and invertebrate features before and after the operation.
More about your plans for this takeover?
The project will make use of data that have already been collected over many years, primarily through the various long-term monitoring projects that have been undertaken at Marion Island over many years. The focus of our work currently is to fill some pre-eradication (baseline) data on vegetation and invertebrates. This particular work was initiated during the 2022/23 period, and will continue in 2023/24. The takeover period will be used to provide training and orientation to the new Marion80 overwintering team member (Camilla Smyth) and for the current Marion79 Mouse-Free Marion overwintering team member (Elsa van Ginkel) to hand over the field-work responsibilities to Camilla.
The work includes standard invertebrate and vegetation survey techniques to establish a baseline that can be used to monitor how these ecological parameters change following the eradication of invasive mice. These surveys will repeat and build on historical surveys that have been undertaken on the island previously.
We will also be undertaking further bait trials and weather monitoring to help inform the planning of the baiting operation.
