Poisoning of vultures is becoming increasingly frequent and represents a worldwide threat to all vulture populations. This man-made threat can be inflicted directly or indirectly upon vultures. Certain anti-inflammatory drugs used on domestic animals and remain present in their carcasses and can be toxic or life-threatening for vultures feeding upon them. Vultures can also be intoxicated by other substances artificially found within their bodies. Illegal shooting of large raptors remains an issue, even when not fatal, the shots can inflict sequelas or the side effects of the subsequent lead poisoning can remain latent. LPO Grands Causses aims to sytematically recover any dead vultures or other large raptor species for autopsy and veterinary analysis to determine the presence of leador other toxins. The second aspect of this project involves developing a routine for daily monitoring and awareness raising with various stakeholders: livestock farmers, farming bodies, local autorities, an hunters. Trials of lead-free ammunition are underway having been developed and executed in partnership with the Cevennes National Park, LPO Grands CAusses and the Hunters Federation of Lozere within the framework of a project supported by the European Commission .
