60,000 Antelopes Died in 4 Days — And No One Knows Why

It started in late May.

When geoecologist Steffen Zuther and his colleagues arrived in central Kazakhstan to monitor the calving of one herd of saigas, a critically endangered, steppe-dwelling antelope, veterinarians in the area had already reported dead animals on the ground.
“But since there happened to be die-offs of limited extent during the last years, at first we were not really alarmed,” Zuther, the international coordinator of the Altyn Dala Conservation Initiative, told Live Science.

But within four days, the entire herd — 60,000 saiga — had died. As veterinarians and conservationists tried to stem the die-off, they also got word of similar population crashes in other herds across Kazakhstan. By early June, the mass dying was over. [See Images of the Saiga Mass Die-Off]

Now, the researchers have found clues as to how more than half of the country’s herd, counted at 257,000 as of 2014, died so rapidly. Bacteria clearly played a role in the saigas’ demise. But exactly how these normally harmless microbes could take such a toll is still a mystery, Zuther said.

“The extent of this die-off, and the speed it had, by spreading throughout the whole calving herd and killing all the animals, this has not been observed for any other species,” Zuther said. “It’s really unheard of.”
