UFS scientists contribute to effectiveness of vulture restaurants

Endangerd read more — Prof Aliza le Roux and Dr Mpho Ramoejane at the vulture restaurant, nearly 30 km from Clarens. This is a safe space for vultures to feed, in an effort to increase their declining numbers.

Endangered bird species such as the Cape and bearded vultures attract bird enthusiasts from afar. These birds are close to extinction in Southern Africa and classified as near threatened on the International Union for Conservation Nature (IUCN) list, with a strong global decline in their numbers.

A viewing hide constructed by honorary rangers in the Golden Gate Highlands National Park, about 30 km from Clarens in the Eastern Free State, offers tourists the opportunity to view and photograph the birds as they feed at one of South Africa’s close to 200 vulture restaurants.

This tourist attraction is situated in a good location from a conservation perspective, with vulture colonies and – importantly – water close by, according to Prof Aliza le Roux.

Prof Le Roux, Associate Professor in the Department of Zoology and Entomology on the Qwaqwa Campus of the University of the Free State (UFS) and affiliated to the Afromontane Research Unit (ARU), is working with one of her students, Agnes Mkotywa, on a study regarding the effectiveness of this feeding site.

Poisoned carcasses big threat to vultures

She said there are quite a few vulture restaurants in the area, with the most famous one at Giants Castle.

A vulture restaurant is an area where park rangers drop non-poisoned carcasses, mostly donated by nearby farmers. Poisoned carcasses, bait for other animals such as jackals and caracals, are one of the biggest threats to vultures.

The vulture restaurants, an effort to get vulture populations to grow, are within the reach of Cape and bearded vultures. But, as found in Mkotywa’s study, the initiative has its shortcomings.

Prof Le Roux said the current structures are open, and black-backed jackals come to feed any time of the day and night. “There is more feeding of the jackals than the intended vultures, and the current structure does not protect the vultures against the jackals,” she said. Jackal activity at the vulture restaurant is significantly higher than elsewhere in the park, as supported by camera traps set up in the park by Dr Mpho Ramoejane, currently an ARU postdoctoral researcher.

Raised platform a possible solution

“This is one of our primary research findings. A possible solution is to put up fences. It will, however, keep everything else out and will be an eyesore from a tourist perspective. A raised platform that could exclude the jackals and still provide the vultures with a large landing place, might work,” Prof Le Roux added.

Another finding was that carcasses are not dropped regularly enough. Vultures cannot predict when there will be food.

These findings will be published in peer-reviewed outlets, but it will also be communicated to the management of the South African National Parks (SANParks) to address the problem. “SANParks is involved in the project and wants the information. They said they needed the information and will build on it,” said Prof Le Roux.

Once the suggested changes are implemented, she is excited to scientifically document how these changes are making a difference. This has the potential to guide the management and development of vulture restaurants elsewhere in South Africa and the world.

Moeletsi Mbeki discusses South Africa’s political economy

South Africa’s ongoing problems do not have their origin in the apartheid dispensation but in the British colonial period. This is according to the well known businessman and political analyst, Mr Moeletsi Mbeki, who was speaking during a guest lecture at the University of the Free State.

Mr Mbeki said the high unemployment rate among Blacks arose from the destruction of the Black small farming class in the last third of the 19th century to provide cheap labour to the developing mining sector. He said the notorious Land Act of 1913 was not the root of Black people’s loss of land but merely the legal formalisation thereof. Mr Mbeki emphasised that as long as it was argued that South Africa’s problems arose during the apartheid dispensation, problems would remain unsolved.

Regarding South Africa’s future, Mr Mbeki argued that three issues in particular were important – South Africa’s industrialisation, which ground to a halt in the 1970s, should be revived; the large scale training of industrialists with special emphasis on mathematics, science and the broader education system; and post-nationalist politics, of which parties such as Zimbabwe’s MDC, Zambia’s MMF and Mauritius’s MMM were outstanding examples.

The guest lecture was presented by the Department of Philosophy. More than 200 people attended the lecture and participated enthusiastically in the question and answer session. Afterwards, Mr Mbeki said he was impressed with the high level of the questions asked by students, which he said gave him hope for South Africa’s future.
