A new population census from Kazakhstan has revealed an increase in saiga
antelope numbers from 152,600 to 334,400 within just two years, offering a
glimmer of hope for a critically endangered species that has been in
freefall for decades.
The weird and wonderful saiga – distinguished by its large, bulbous nose –
once roamed the steppes of Central Asia in vast nomadic herds, millions
strong, a spectacle said to have rivalled the modern-day wildebeest
migration in East Africa.
It is superbly adapted to the harsh conditions of the remote wilderness
areas that it favours, but has no defence against the threats posed by
humans. In the 19th century, it was almost annihilated by the kind of
unbridled hunting spree that drove the bison to virtual extinction in North
America.
Legal protection ensured its survival, but the respite was only temporary,
and a poaching free-for-all triggered by the break-up of the former Soviet
Union in 1991 caused a near-catastrophic fall in numbers, leading to an
unprecedented loss of more than 95% of the global population in the
following decade – one of the fastest recorded declines for a mammal.
In recent years, the saiga population has also been decimated by a number of
mass die-off events resulting in the loss of hundreds of thousands of
antelopes, with disastrous consequences for a species already pushed to the
brink by hunting and habitat loss.
The saiga’s natural resilience, buoyed by a suite of well-directed
conservation measures, has led to a series of mini-recoveries, but the
species is still in grave danger, with some groups struggling for survival.
Three of the world’s five remaining populations of saiga are found in
Kazakhstan – the others are in Russia and Mongolia.
Fauna & Flora International (FFI) is a partner in the Alton Dala
Conservation Initiative, which aims to protect and restore Kazakhstan’s
steppe, semi-desert and desert ecosystems and the species they harbour,
including the critically endangered saiga. This broad coalition includes the
Association for the Conservation of the Biodiversity of Kazakhstan (ACBK),
the Committee of Forestry and Wildlife of the Ministry of Agriculture of
Kazakhstan, Frankfurt Zoological Society and RSPB.
With support from the US Fish and Wildlife Service, the Species Fund and
Restore Our Planet, FFI is focusing its conservation efforts on the
smallest, remotest – and most threatened – of the country’s three saiga
populations, on the Ustyurt Plateau. This vast transboundary desert – shared
with Uzbekistan and Turkmenistan – covers an area of roughly 200,000 square
kilometres.
The Ustyurt saiga population is a prime target for poachers, particularly
the male antelopes, whose horns are among the myriad animal parts hoovered
up in industrial quantities for use in traditional Asian medicine.
Working with ACBK and the Kazakhstan government, FFI is monitoring the
distribution and movement of saiga, and has supported the establishment and
training of a new ranger team, and the deployment of sniffer dogs, to help
deter and foil illegal trade in saiga horn within Kazakhstan and across the
border, as well as raising awareness of the antelope’s importance within
communities through educational activities and the promotion of an annual
‘saiga day’.
Those efforts are now being rewarded. The use of satellite collaring and
telemetry to monitor saiga movements has not only helped combat the poaching
threat, but also enabled rangers to pinpoint the antelopes’ calving grounds
for the first time in many years.
Aerial surveys that ACBK conducted in the course of the national saiga
census revealed dramatic increases across all three Kazakhstan sites, but
the Ustyurt Plateau has enjoyed a particularly strong resurgence; numbers
have risen to 5,900, an increase of almost 130% since 2017.

Although relatively small, this population has a disproportionately
significant role to play in the long-term survival of the saiga. Such
metapopulations, as they are known in the trade, have a wider value that
transcends their actual size, particularly in the context of the
unpredictable – and, to date, unpreventable – mass-mortality events that
pose an ever-present threat to the species as a whole.
In May 2015, the largest saiga population in Kazakhstan – and the world –
suffered a devastating mass die-off, precipitated by an outbreak of
haemorrhagic septicaemia, which wiped out an estimated 70% of the global
adult saiga population in less than a month.
In the context of such cataclysmic events, which can virtually obliterate an
entire subpopulation in one fell swoop, the Ustyurt Plateau saiga subset
assumes even greater importance.
The latest survey results are a real shot in the arm for saiga conservation,
but everyone involved is painfully aware that the next setback could be just
around the corner. Eternal vigilance is the name of the game, a point
emphasised by Bakhtiyar Taikenov, head of the Ustyurt ranger team: “This is
fantastic news, especially for the Ustyurt population, which many in
Kazakhstan had already given up. When we all work together with the right
approach, we can achieve a lot. But there are still various threats and
disaster can strike at any time, so we have to be prepared. The more we can
do about poaching and other threats to saiga, the better the chances of
population recovery in the event of another natural disaster.”
