Africa’s vulture populations face the prospect of collapsing in much the same way as vulture species in Asia, experts warn, having already declined by an average 62 percent over the past three decades.Key threats include poisoning by ranchers and poachers and for belief-based use, as well as accidental drowning in farm water reservoirs and ingestion of lead ammunition.To address the threats, managers of conservation areas and private game reserves in South Africa have agreed to create “vulture safe zones” that will do away with these practices to provide safe havens for existing vulture populations.Conservationists say it’s also important for managers in South Africa to work with their counterparts in neighboring countries that are part of the vultures’ range, and to tackle the trade in vulture parts used in traditional medicine practices. Howick, SOUTH AFRICA – The first of at least five new “vulture safe zones” in Southern Africa are about to take off as private landowners and other partners join the battle to save Africa’s imperilled carrion clean-up birds. Africa’s vulture populations have declined by an average of 62 percent over the last three decades – with seven species crashing by 80 percent – mirroring the dramatic collapse of several Asian species. These were among findings of recent research presented by leading animal scientist Brent Coverdale at the Conservation Symposium, one of South Africa’s biggest annual gatherings of conservationists, environmental scientists and wildlife experts. “We need to think globally and act locally,” Coverdale told attendees at the event, held this year in the town of Howick from Nov. 4-8. “We all know of the Asian vulture crisis, where we had vulture declines of 90-95 percent in the early 1990s. It’s something that drives us. We do not want to be sitting in the same boat, where one day people will ask, so what were we doing when the crisis was happening?” Gyps genus at India’s Soheldev Wildlife Sanctuary.

They played a particularly important role in the ecosystem, consuming the remains of the millions of cows in carcass dumps; India has 500 million cows raised for milk, but not eaten by the majority Hindu population. In the early 1990s, vultures started dropping dead. Hundreds of thousands died before scientists identified a culprit: diclofenac, an anti-inflammatory used by vets. Vultures feeding on carcasses containing the drug died swiftly of kidney failure. Conservation India says around 40 million vultures perished. Coverdale, who works for Ezemvelo KZN Wildlife, a South African government conservation body, stressed the vital roles that vultures play in ecosystems. By swiftly stripping the flesh from dead animals, they reduce the spread of disease as well as the number of animals scavenging at rotting carcasses. “We really can’t afford to lose them. In nine minutes they can clean up an entire carcass,” Coverdale said. There are several reasons for the decline of African vultures, but deliberate or accidental poisoning is the biggest peril. Gareth Tate, the Birds of Prey Programme manager for the Endangered Wildlife Trust (EWT), says poison accounts for about 60 percent of vulture deaths in the Southern Africa region. Some poisoned bait is laid by livestock owners to kill predators, like jackals. Vultures feeding off the carcasses subsequently die, often in significant numbers. Others are poisoned deliberately to harvest body parts for making muthi, traditional medicine potions. In one of the worst mass-poisoning cases on record, at least 540 vultures were killed near Botswana’s Chobe National Park earlier this year after feeding on elephant carcasses spiked with a potent poison by wildlife poachers, in an apparent effort to conceal illegal activities from rangers. In this case, the carcasses were not removed for two to three weeks, resulting in an extended cycle of death as more vultures and other scavengers arrived to feast.

The misconception that these carrion birds have psychic powers, or can ‘see into the future’ has led to a demand for vulture’s heads and other body parts. Andre Botha, EWT’s Vultures for Africa Programme manager, said that while it was hard to quantify the numbers of vultures killed for belief-based use, recent studies estimated that direct persecution of vultures either for muthi or food was about 29 percent of all vultures killed in Africa. While Botha was not at this year’s symposium, he said the belief-based use of vultures was a significant and growing threat to the continent’s vultures”. This, he said, needed to be openly discussed “with the same degree of vigour as is the misconceptions associated with the use of rhino horn” in Asia. “It is an inconvenient truth that must be addressed,” added Botha. Accidental drownings in farm water reservoirs have also been reported, and research has flagged lead bullet fragments in animal carcasses as an increasing concern. But BirdLife South Africa vulture project manager Linda van den Heever said many landowners and game ranch owners seemed resistant to halt the use of lead ammunition on their land, complaining that lead-free ammo is less effective and more expensive. At the symposium, several researchers outlined the results of recent partnerships to arrest the growing decline of vultures in Southern Africa. One initiative involves creating “vulture safe zones” — large areas where landowners commit to managing their land in ways that will provide safe havens for existing vulture populations. According to EWT, the emphasis of the vulture safe zones will be to encourage positive action, “focusing less on prohibition and negative messaging, and more on sound environmental practices that could provide landowners with reputational and economic benefits.” In support of the program, participating landowners have agreed to stop baiting carcasses with poison, and modify concrete water reservoirs to reduce the risk of accidental drowning.
