Vultures, Too, Are Dying From Masai Mara Poison Attack

Two days ago eight members of the Marsh Pride, made internationally famous on the long-running television series Big Cat Diary, were poisoned inside the Masai Mara National Reserve. The lions fed on a cow carcass baited with a highly toxic carbamate pesticide; the exact identity of the poison will be revealed after laboratory testing. Two of the lions have succumbed to poisoning, the others are said to be recovering. Also poisoned were at least six White-backed and Rüppell’s vultures, though this will never make the headlines.

That there has been immediate international condemnation of this atrocious act should not surprise anyone compassionate about wildlife conservation. There are of course many more facets to this story and anyone who is aware of the management issues in and around the Mara reserve over many decades will not be shocked that it has come to this. While vastly improving the management of this particular reserve should be one outcome, the larger issue of wildlife poisoning needs to be urgently addressed, and not just in Kenya, but across Africa.

The unrestricted access to pesticides and other poisons such as strychnine and cyanide must be curtailed immediately through tighter controls on the distribution of these highly toxic poisons that are widely used to kill wildlife.

This is not just an issue of a bunch of “tree-hugging environmentalists” (as we’ve been called) trying to save wildlife. Poisons are widely used to harvest fish and bushmeat, which are then consumed by unsuspecting customers. Poisons are being used for poaching elephants and rhinos. The use of poisons is so reckless that sometimes entire waterholes are poisoned to kill elephants, or to harvest birds and antelopes for bushmeat. The numbers of non-target species killed by tainting waterholes is staggering, while the effects on humans and their livestock that also rely on these water sources is unknown.

The poisoning of the famous Marsh Pride should be a catalyst for African governments and those involved in wildlife and environmental issues in Africa to have a serious discussion about curtailing the easy access to highly toxic pesticides and other poisons. The abuse of pesticides goes far beyond poisoning wildlife.

    When I was there, domestic cattle are actually grazing inside the reserve every day. This is the sort of thing that is bound to happen in the grab for more secure grazing land

  • Hellen Achiando

    @Weng Lim very true and grazing was the cause of this poisoning yesterday on the news two Maasai Men were arrested but the sad bit it is the pastoralist that are grazing where they are not supposed to, there are cases where they kill the lion themselves by hunting them down. I hope these two that were caught will be punished to be an example to the rest.
    The people that need awareness and education are the locals , more initiatives should be made to involve them in protecting this wild animals .

    What else did you expect? I’ll be the devil’s advocate. The Maasai who poisoned the lions neighbour the hallowed Mara park. It’s their ancenstral land. But the only benefit they accrue from it is only when they are retained to jump up and down for visiting westerners, who by the way book their safaris in London and other world capitals and leave all the money there. They only bring a few dollars and sterling pounds to buy curios and other mundane items. One renowned banker actually said Kenya would make more money by killing or giving away all its wildlife and using the land for farming. The poisoning of the lions is tragic. But it mirrors what most communities near national parks feels about the animals. It’s a real case of Animal Farm, only that the animals are more important than the people.

    L’odio verso gli animali e’ la sconfitta dell’intelligenza umana è colui che non la rispetta non merita di vivere.

  • Noelia Vidal

    What can we do???

  • kevin

    Can nat geo please come and take all this animals to some zoo somewhere in the west. Only yesterday a hyena mauled a woman to death. Well no hue and cry about it! Instead we are hear crying tears about lions.

  • Neville 100c Bt66-6jb

    These sub humans should be found at all costs then taken out snd shot no questions asked! Full stop!


    well well this shows that only the wearer of the shoe knows where it hurts. leopard ate my sheep and goats the wildlife guys came saw said SORRY left and u think if l saw the leopard again l would hug it and say its a foreign income earner???? to a farmer a wild animal is a pest and what did they tell u about pests in school???
    if you called the wildlife guys n say you saw poachers they will send a big armed team with sniffer dogs call them say your cows are been attacked by a lion they will send two or three officials to come see what happened so the farmers in Masai land did what they had to do PROTECT THEIR LIVELIHOOD!

  • Josphat Rasugu

    This was bad and against the law. The government tried to get the people who were responsible. I hope they were punished and taught how beautiful wildlife is.

  • allan
