Catastrophic Collapse of Saiga Antelope Leaves 120,000 Dead in a Month

Kazakhstan – An aerial survey conducted as part of a national monitoring program earlier this year estimated that the saiga antelope population numbered approximately 250,000 animals prior to this mass die-off, which has therefore halved the total population in about one month.

Preliminary analysis indicates that a combination of environmental and biological factors is contributing to this catastrophic event, which has seen four large birthing herds of the critically endangered Saiga antelope wiped out since mid-May this year. Primarily mothers and calves are among the carcasses; not a single animal has survived in the affected herds.

At the request of Kazakhstan, the Secretariat of the Convention on the Conservation of Migratory Species of Wild Animals (CMS) dispatched an emergency mission last week with experts from the Royal Veterinary College in the United Kingdom and the Food and Agriculture Organization to assist on the ground with post-mortem examination, analysis and to contribute to a working group.

According to information received from the members of the CMS expert mission, it is becoming clear that two secondary opportunistic pathogens, specifically Pasteurella and Clostridia, are contributing to the rapid and wide-spread die-off. However, the hunt for the fundamental drivers behind the mass mortality continues since these bacteria are only lethal to an animal if its immune system is already weakened.

The animals die within hours of showing symptoms, which include depression, diarrhea and frothing at the mouth.

“They get into respiratory problems, they can’t breathe easily. They stop eating and are extremely depressed; the mothers die and then the calves are very distressed and then they die maybe one or two days later,” said Richard Kock from the Royal Veterinary College in London.

While mass mortality events are not unusual for the saiga antelope, they typically affect far smaller numbers of animals, on the order of about 10,000 saigas. The magnitude of this event, therefore, is unprecedented, given the population’s large size.

Conservationists have made great progress with Saiga in recent years, due to international efforts to reduce poaching and monitor their populations. This die-off is a severe setback to the conservation effort because it has wiped out four of the six calving herds in the largest remaining – and best protected – saiga antelope population, in central Kazakhstan.

Steffen Zuther, head of the Association for the Conservation of Biodiversity in Kazakhstan (ACBK), was monitoring calving in one of the herds containing thousands of affected animals.

“Over two days  [in the herd I was studying] 80% of the calving population died,” he told the BBC.
The whole herd then died within two weeks.

    Kazakhstan suggests extending highway from China to Russia’s St. Petersburg
    29/05/2015 TASS

    Kazakhstan President Nursultan Nazarbayev said on Friday he will ask Russian Prime Minister Dmitry Medvedev to extend to St. Petersburg a new highway that will go through Kazakhstan from its border with China.

    “We are finishing the construction of the most modern highway from the border with China to Russia. This is 2,700 kilometers [1,677 miles]. I will ask Dmitry [Medvedev] to extend this highway,” Nazarbayev said at the meeting with the heads of governments of the Commonwealth of Independent States (CIS).

    The Kazakh leader explained that the idea relates to the construction of the road from Kazan, in Russia’s Tatarstan republic and then to St. Petersburg, Russia’s second largest city. He said the creation of this highway would help the implementation of promising business projects along the road.

    The project will also encourage the development of the economies of Central Asian republics – Kyrgyzstan, Uzbekistan, Turkmenistan and Tajikistan, Nazarbayev said.

    Plight of the Saiga

    I hope to God, the causes are natural1 I align myself to africa and its wildlife, and many mass deaths are not by natural causes! For instance, they are already physically changing the natural migratory route of the wildebeest in tanzania, by driving convoys of lorries on a daily basis along the route of the “proposed” highway.
