The history of poisoning in Bulgaria Since 50‘s the use of poison baits is a common practice in the Balkan countries including Bulgaria; In the 50‘s and 60‘ s the Forestry authorities and hunters were using poison baits to control “harmful” mammals, like bears, wolves and foxes. The main substances used strychnine; For only two decades most of the raptor species were almost entirely extirpated due to poisoning, although the vultures have never been declared as “pest species” The use of poisons was prohibited in 1967, however the last campaign to exterminate carnivores is done in 1989 – 1990;
Because of the strychnine poisoning the Black vulture went extinct as a breeder from Bulgaria and NW Balkans. Griffons, the raven and the wolf were on the edge of extinction in BG; In 2003, at least 5 Egyptian vultures were poisoned near Krumovgrad, Eastern Rhodopes. Since 1994 at least 16 Egyptian vultures were poisoned in BG; In BG the highest recorded mortality after poisoning occurred in 1996, when 5 adult, 1 subadult and 5 juveniles G.fulvus, were found dead (Hristov, 1997);
The main reasons: Loses of livestok caused by wolves (human – predator conflict) Conflict between hunters and shepherds/farmers and between local pople (human – human conflict)
The main substances used: Strychnine – banned but still available, widely used in the 50‘s and 60‘s against wolves; Carbamates - Carbofuran(Furadan) – pesticide banned in the EU; used in Kenya to poison lions; Methomyl(Lanate) – used by pigeon breeders; Poison coctails or the illegal use of legal substances

Egyptian vulture mortality 1997 – 2015: The most frequent humaninduced reason of death was poisoning (86%) followed by direct persecution (8%). Adult birds the most frequent victim! 1Saravia,

`Ready for action
Where
Work in 3 regions Eastern Rhodopes and Kresna gorge with focus on vulture species Sakar and Strandzha mountains focusing the imperial eagle population
The work load so far: Kresna gorge – 2 patrols, 3450±1060 m per patrol Eastern Rhodopes – 33 patrols, 1316±899 m per patrol Sakar mountains/Strandzha mountains – 12 patrols, 1238±730 m per patrol
Case studies...
• • • •
• THE VERY FIRST CASE (OCTOBER 2016) 7 wolves, 5 sheperd dogs, 2 foxes, 1 stone marten, 1 hedgehog, 1 wild boar, one griffon vulture (reported from local hunter as falling from the sky). As poison baits were used intestines,head and legs from sheep and a carcass of a calf killed by wolves. The police and the prosecuters started an investigation on the case We suspected either strychnine or lannate (methomyl)
Kresna gorge – March 2 30+ Griffons dead
Kresna gorge October 2017
