Catastrophic Collapse of Saiga Antelopes in Central Asia Thu, May 28, 2015
The aerial survey conducted as part of the national monitoring programme earlier this year estimated that the Betpak-dala Saiga population numbered approximately 250,000 animals prior to this mass die-off, which has therefore halved the total population.
Bonn/Astana, 28 May 2015 - More than 120,000 saiga antelope have been confirmed dead in central Kazakhstan, representing more than a third of the global population. This is a major blow for conservation efforts given that saigas have in the past ten years only just started to recover from a global population size of less than 50,000 animals following a 95% crash in numbers.
Preliminary analysis indicates that a combination of environmental and biological factors is contributing to this catastrophic event, which has seen four large birth aggregations of this critically endangered antelope eradicated since mid-May this year. Primarily mothers and calves are amongst the carcasses; not a single animal survived in the affected herds.
Erlan Nysynbaev, Vice Minister of the Ministry of Agriculture of Kazakhstan stated "This loss is a huge blow for saiga conservation in Kazakhstan and in the world, given that 90% of the global saiga population is found in our country. It is very painful to witness this mass mortality. We established a working group that includes all relevant experts, including international ones, and are determined to identify the causes and undertake all possible efforts to avoid such events in the future."
At the request of Kazakhstan, the Secretariat of the Convention on the Conservation of Migratory Species of Wild Animals (CMS) despatched 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 the working group.
CMS Executive Secretary, Bradnee Chambers said "Authorities in Kazakhstan are responding quickly to this disaster and are working hard to solve the mystery behind this mass saiga die-off. I am pleased that the international expert mission we were able to send, at very short notice, is now contributing to these efforts".
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 of the mass mortality continues since these bacteria are only lethal to an animal if its immune system is already weakened.
"Experts are working around the clock to investigate the impacts in terms of wildlife health of the relatively high rainfall observed this spring, the composition of the vegetation and other potential trigger factors including a suite of viruses. None of the data analysed to date indicates that rocket fuel is related to the mass die-off. Fresh laboratory results are becoming available every day," says Aline Kühl-Stenzel, Terrestrial Species Officer at the UNEP/CMS Secretariat, who has been supporting the expert mission remotely from the Convention's headquarters in Bonn, Germany.
Kazakhstan has been actively implementing the CMS Memorandum of Understanding concerning Conservation, Restoration and Sustainable Use of the Saiga Antelope ( Saiga MOU ), not least through establishing new protected areas and anti-poaching patrols. Other partners that have signed the MOU, namely the Frankfurt Zoological Society and the Association for the Conservation of Biodiversity of Kazakhstan (ACBK) have been providing funds, as well as technical and logistical support for the emergency response, including the CMS expert mission. The Saiga Conservation Alliance, another partner of the MOU, has provided scientific input.
The aerial survey conducted as part of the national monitoring programme earlier this year estimated that the Betpak-dala population numbered approximately 250,000 animals prior to this mass die-off, which has therefore halved the total population. It is likely that final estimates may extend beyond 120,000 dead saigas since the counting of carcasses by emergency response teams is continuing. It is however becoming clear that the mass die-off has come to an end and that several GPS-collared animals are still alive in herds that were not affected by the mortality event.
Mass mortality events are not unusual for saiga antelopes, with a case occurring as recently as 2010 with 12,000 dead animals. However, the scale of the current event is unprecedented relative to the total population size. Often these mass mortality events occur in the birth period, when Saiga females come together in vast herds to all give birth within a peak period of less than one week.
"Saiga antelopes often have twins and populations are able to rebound quickly. Our hope is that if we can control what is driving these mass mortality events as well as tackle the number one threat to saigas - wildlife crime and poaching - populations will be able to recover. Collaboration among all stakeholders is vital. Kazakhstan is leading the way and I look forward to the Range States putting in place strong policies at the CMS Saiga meeting," said Chambers.
The third Meeting of Signatories to the CMS Memorandum of Understanding concerning Conservation, Restoration and Sustainable Use of the Saiga Antelope ( Saiga MOU ) is scheduled for the autumn of 2015. Consumer countries of saiga horn will also be present at the table as well as the CITES Secretariat, to review implementation and adopt an updated work programme, including measures for wildlife health management. The MOU is part of the CMS Central Asian Mammals Initiative (CAMI), a framework for the conservation of large mammals across the region, and was adopted by the CMS Conference of the Parties in November 2014.
Notes to Editors:
The Convention on the Conservation of Migratory Species of Wild Animals (CMS) aims to conserve terrestrial, aquatic and avian migratory species throughout their range. It is an intergovernmental treaty, concluded under the aegis of the United Nations Environment Programme, concerned with the conservation of wildlife and habitats on a global scale. To date 120 State Parties have ratified the Convention.
The Memorandum of Understanding concerning Conservation, Restoration and Sustainable Use of the Saiga Antelope (Saiga spp.) is an intergovernmental instrument developed under the auspices of CMS dedicated to the conservation of saiga antelopes across their five Range States (Kazakhstan, Mongolia, the Russian Federation, Turkmenistan and Uzbekistan). The MOU has been in force since 2006 and has been signed by all Range States, as well as eight Cooperating Organizations, namely the Association for the Conservation of Biodiversity of Kazakhstan, Fauna and Flora International, the Frankfurt Zoological Society, the International Council for Game and Wildlife Conservation (CIC), IUCN/SSC, Saiga Conservation Alliance, Wildlife Conservation Society and WWF International.
The Central Asian Mammals Initiative (CAMI) is a CMS instrument developed by the Range States of Central Asia and adopted at COP11. CAMI provides a common framework to coordinate conservation activities in the region and coherently address major threats. It is based on a series of activities each focused on single species (including existing MOUs/Action Plans and those in development); and activities to address urgent and major threats faced by all or most of the species.
