Saiga Antelope: Conservation After Mass Die-Off Events

Saiga antelopes are ancient Central Asian ungulates that have experienced catastrophic mass mortality events, with welfare implications for millions of individual animals and conservation urgency for a species that was already critically threatened.

Key Facts

In 2015 over 200,000 saigas — approximately 60% of the world population — died within a few weeks from a bacterial infection triggered by unusual weather conditions
Saiga are listed as Critically Endangered by the IUCN
Their extraordinary nose acts as a natural air filter and temperature regulator in extreme steppe climates
Populations have historically recovered rapidly due to high reproductive rates — females can give birth to twins
Habitat loss, poaching for horns used in traditional medicine, and climate change are the primary long-term threats
Males are disproportionately targeted by poachers, creating severely skewed sex ratios
The 2015 die-off is linked to Pasteurella multocida bacteria that became lethal under unusual temperature and humidity conditions
Multiple smaller die-off events have occurred in other years, suggesting increasing climate-linked mortality risk

Welfare Considerations

Mass die-off events cause suffering on an extraordinary scale. Individual animals experience severe septicaemia with haemorrhagic symptoms, acute respiratory distress and rapid death over days. Calves orphaned by maternal deaths face starvation and exposure. The psychological and social disruption to a highly gregarious species during such events compounds individual suffering. Between major die-offs, individual saigas face chronic threats from habitat degradation that reduces food availability and increases the energetic cost of movement, particularly during seasonal migrations through increasingly fragmented steppe landscapes.

What You Can Do

Support organisations monitoring saiga populations and responding to die-off events
Avoid products containing saiga horn, which drives illegal poaching
Advocate for international coordination on saiga conservation between range country governments
Support research into climate-linked disease risk to improve early warning systems
Donate to saiga habitat protection and anti-poaching initiatives in Kazakhstan and Russia
Raise awareness about saigas as one of the most charismatic and threatened steppe animals
