Vultures as a group are the most threatened birds in the world. Of the 23 species of vultures in the world, over 70% of them have an unfavourable conservation status, meaning that they’re at risk of going extinct.
Poisoning is the biggest threat facing vulture populations in Africa, and in particular this threat has grown rapidly with the increasing slaughter of elephants by poachers. Poisoning associated with ivory poaching now accounts for one third of all vulture poisonings since 1970 and is currently the biggest cause of vulture mortality.
New research led by the Trust’s Head of Conservation and Research, Dr Campbell Murn, published in Oryx – the International Journal of Conservation – has taken the first steps towards assessing the risk from poisoning associated with elephant poaching (A clear and present danger: impacts of poisoning on a vulture population and the effect of poison response activities). Using a modelling programme called VORTEX, we assessed a population of critically endangered vultures being affected by poisoning.
According to the model, poisoning caused large population declines (50-100%) in almost all cases where it occurred. In more than one case, the average time to extinction was 50-60 years. The results show that carcasses of elephants killed by poachers and laced with poison are a clear and present danger; they will lead to local extinctions of vulture populations.
More encouragingly, the analysis also showed that where field staff are trained and equipped to neutralise poisoned carcasses and reduce poison-related mortalities, the probability of local populations going extinct is reduced significantly. These important research results underpin the Trust’s work of providing Poison Response Kits to fieldstaff in southern Africa. Along with our partners at the Endangered Wildlife Trust we also support the ongoing training of fieldstaff to deal with poison events when they occur.

In 2015, our Head of Conservation and Research, Dr Campbell Murn, co-authored a paper that led to the uplisting of six of Africa’s eleven species of vulture to critically endangered. The paper, Another continental vulture crisis: Africa’s vultures collapsing toward extinction, showed that Africa’s vultures are facing a range of specific threats, the most significant of which are poisoning and trade in traditional medicines, which together have accounted for 90 per cent of reported deaths.
Each poison response kit costs £300 and after a poisoning incident each kit needs to be replenished at a cost of £180. You can help us raise the funds needed to provide these kits that could save thousands of vultures and other wildlife from an unnecessary death due to poison.
Poison response kits contain a range of equipment and first aid materials and are designed to reduce the impacts of poisoned carcasses on wildlife. Often, poisons are so toxic that vultures can die with food still in their mouths. This means that work must take place as soon as possible to prevent further deaths. With a quick response and the effective use of Poison Response Kits, hundreds of animals can be saved from death by poisoning.
from just £3 a month, you can make a real difference.
