What is happening?
In the early 1900s, the African penguin population thrived along the Namibian and South African coasts, numbering between 1.5 and 3 million individuals, with nearly 1 million pairs inhabiting Dassen Island alone. Tragically, by the mid-1950s, rampant egg harvesting and guano removal decimated their numbers, leaving only 10% of the population remaining. Since 1979, when comprehensive surveys of major South African colonies began, the breeding pairs have plummeted from approximately 55,200 to a stark 10,000 in 2021.
Today, the African penguin population stands at a mere 10,000 breeding pairs in South Africa and 4,000 in Namibia, marking the lowest figures ever recorded. With such an alarming decline, the species faces functional extinction by 2035, meaning their numbers will dwindle to a critical point where breeding cannot sustain the population. Classified as Endangered on the Red List by the International Union for Conservation of Nature (IUCN) in 2013, urgent action is imperative to ensure the survival of African penguins in the wild. If we delay, the opportunity for future generations to witness these remarkable creatures in their natural habitat will vanish.
The time for action is now.
Why is this happening?
The decline of African penguins in recent years can be largely attributed to the scarcity of their prey, resulting from shifts in the distributions of small pelagic fish stocks and competition with commercial purse-seine fisheries. Despite the success demonstrated by an island closure experiment conducted a decade ago, which highlighted the benefits of restricting fishing in areas near penguin colonies, no lasting solutions have been put into action following years of negotiation.
​
Additionally, the proximity of many African penguin colonies to major shipping routes and ports poses significant threats. The expansion of harbors and increased ship traffic heighten the risk of oil and noise pollution, with ship-to-ship bunkering exacerbating the danger, particularly in areas like Algoa Bay where four oil spills have already occurred since 2016.
Furthermore, the maritime industry's activities, including seismic surveys for oil and gas exploration, present looming threats of marine noise pollution. Changes in breeding habitat further compound the challenges faced by African penguins. While guano harvesting, which previously provided nesting material, is now prohibited, the lack of suitable nesting sites remains a concern. Efforts to address this issue include revegetation initiatives at some colonies and the testing of artificial nests. Additionally, the disease poses an ongoing threat to penguin populations.
To combat these multifaceted threats, comprehensive management plans tailored to each penguin colony are crucial.

What is the importance of penguins?
Penguins are integral to the health and balance of marine ecosystems, playing a crucial role in nutrient cycling. Through their activities, they transport vital nutrients from the ocean to their colonies on land, enriching adjacent terrestrial and marine ecosystems. Additionally, penguins contribute to the maintenance of fish populations by selecting smaller or weaker individuals, thus promoting the overall health of fish stocks. Their behavior of herding shoals of fish to the surface also benefits other seabirds, such as gannets, facilitating their hunting efforts.

Beyond their ecological significance, the possible extinction of African penguins would have profound economic repercussions. Not only would it result in the loss of a charismatic species, but it would also disrupt local economies reliant on tourism and conservation. Destinations like Boulders Beach in Simon’s Town and Stony Point in Betty’s Bay, renowned for their penguin colonies, would suffer from decreased tourism, leading to job losses and economic decline. Furthermore, the extinction of the African penguin would signify the loss of Africa's only endemic penguin species, diminishing the continent's biodiversity and cultural heritage. Thus, safeguarding African penguins is not only vital for ecological integrity but also for sustaining local economies and preserving Africa's natural heritage.
