Saiga Antelope

Wallpaper Description:

Saiga antelope have survived since the ice ages — the species has shared the world with woolly mammoths and saber-toothed cats. But catastrophic disease and poaching have put the species in a critical place.Uncontrolled illegal hunting for horns (male horns are exported for the traditional Chinese medicine trade) and meat since the break-up of the former USSR has led to the catastrophic fall in numbers. Selective hunting of young males and subsequent distortion of the sex ratio has affected reproduction: recent research shows that heavily skewed sex ratios are resulting in reproductive collapse (Milner-Gulland et al. 2003). A second significant threat is the destruction of key habitats and traditional migration routes. Agricultural abandonment is a problem in some areas; cattle grazing formerly maintained the grassy species but land abandonment allows another species (Stippa sp.) to encroach, which the Saiga cannot eat. The recent increase in steppe fires is a further cause for concern. Severe winters can cause mass mortality.Red List Category & Criteria: Critically Endangered A2acd ver 3.1

Assessor(s): Mallon, D.P.
Reviewer(s): Milner-Gulland, E.J. & Mallon, D.P. (Antelope Red List Authority)
Justification:
The population has shown an observed decline of over 80% over the last 10 years and the decline is continuing. Severely skewed sex ratios are leading to reproductive collapse.

2003 – Critically Endangered (CR)

1996 – Vulnerable (VU)
Critically Endangered
