Guardians of the Sky: Cape Vultures in South Africa's Potberg Mountains
High above the rugged terrain of South Africa's Western Cape, a remarkable bird species reigns supreme – the Cape vulture (Gyps coprotheres). CapeNature has been dedicated to the conservation and monitoring of these majestic birds for many years within CapeNature's De Hoop Nature Reserve, where the Potberg Mountains provide vital breeding habitat for the only population of Cape vultures in the Western Cape.
These remarkable birds hold a unique place in the ecosystem and culture of southern Africa. Here are some intriguing facts about these winged giants:
- Cape vultures are predominantly found in southern Africa, populating South Africa, Lesotho, Eswatini, and parts of Namibia, Botswana, and Zimbabwe. Their adaptable nature allows them to thrive in diverse landscapes, from mountains to savannas.
- Cape vultures are known for their strong social bonds and the formation of colossal colonies, especially during the breeding season. These gatherings can consist of hundreds of devoted vulture pairs.
- Vultures play a very important ecological role in the environment. Through their scavenging feeding behaviour, they clean up the carcases of dead animals. This reduces the risk of disease outbreaks of pathogens which can be transmitted by decaying or infected carcasses.
The Cape vultures of the Potberg mountains are not just ecological linchpins but also cultural symbols in parts of southern Africa. Vultures typically have long range movements which complicates their conservation. The main threats to vultures are poisoning (deliberate or accidental), collisions with powerlines, and changes in land use patterns and some livestock farming practices. Vultures are also occasionally targeted for the muti trade and sometimes persecuted by farmers who believe that vultures prey on live sheep. Their survival thus relies on the collaborative efforts of government, conservation organisations, and local communities, ensuring that the vultures continue to soar for generations to come.
De Hoop Reserve is 36 000 hectares with its diversity ranging from coastal dunes to the Potberg mountains. During a field excursion to De Hoop in August 2023, various CapeNature staff members gave presentations with Groen Sebenza Intern Kallyn Gunkel presenting on the Cape mountain zebra and Interns Jillian Fredericks and Leandra Knoetze presenting on the Cape vulture. Fieldwork included a long hike up to the vulture colony to do the annual counts and contribute to long-term monitoring of the colony. In addition to the vultures, many other species were spotted such as dozens of Eland, Cape mountain zebra, Rock Hyraxes lining the estuary edges, and a Cape hare.

State of Conservation Report 2026 tracks progress and pressures facing Western Cape biodiversity
The Western Cape’s biodiversity is facing mounting pressure, with a sharp increase in the area affected by fires and more ecosystems and species classified as threatened, according to the Western Cape State of Conservation Report 2026. The report records 107 fires that burned 215 936 hectares during the 2025/26 reporting period – almost three times the 75 174 hectares burned by 97 fires in the previous reporting period.
El Niño raises fire risk as Western Cape prepares for a challenging fire season
The Western Cape is preparing for a potentially challenging wildfire season, with the developing El Niño weather pattern expected to contribute to hotter and drier conditions and an increased risk of wildfires across the province. The South African Weather Service has warned of below-normal rainfall associated with the expected strong El Niño during the coming summer season. While El Niño does not automatically mean that every part of the province will experience drought
Cape fur seal safety remains important this World Rabies Day
On World Rabies Day (28 September), CapeNature is reminding residents and visitors to keep a safe distance from Cape fur seals and to act immediately if they or their pets are bitten, scratched or exposed to a seal’s saliva. Rabies has been detected in Cape fur seals along the South African coastline and by the end of 2025, at least 176 people had been bitten by seals. While most seals do not pose a threat to people, they are wild animals and should never be approached, touched, fed or encouraged to interact with humans.
How Waste Affects Biodiversity and What We Can Do About It
Waste is more than an eyesore. Littered streets, polluted rivers and overflowing landfills are visible signs of a much wider environmental problem. Every year, people generate large volumes of waste, yet much of it is not managed effectively. In South Africa, more than 60% of waste has been reported as ending up in landfills. With service-delivery challenges and many major landfill sites approaching capacity, the pressure on communities and natural ecosystems continues to grow. Both terrestrial and aquatic biodiversity carry much of the impact.
