The Veolia
Environment Wildlife Photography Competition is almost 50 years old.
Co-owned by the Natural History Museum and BBC Worldwide, it hosts different
awards, The
Gerald Durrell Award for Endangered Species amongst
them. I felt like choosing this years’ award, Runner-up by Steven
Winter, to illustrate the situation of endangered tigers.
Having a look
at his website, I see that Steve’s series on tigers illustrate in a very good
manner the essentials of this issue, including the illegal trade of tiger
skins.
Even more
recently, the 2012 Rolex Award for Enterprise was granted to Sergei
Bereznuk, a Russian conservationist and ecologist, Director of
the Phoenix Fund,
an NGO whose mission is to conserve the fauna and flora of the Russian Far
East. The money of the award will be devoted to the continuation of educational
projects in support of the conservation of the Amur Tiger.
These two
prizes have inspired me to devote the first series of posts to these magnificent
animals.
What is their conservation status?
To answer
this question I have reviewed data found mainly in the IUCN Red List of Threatened Species,
documents produced by Traffic, WWF, Panthera,
the Environmental
Investigation Agency (EIA) and the CITES Convention (the
Convention on International Trade in Endangered Species of Wild Fauna and
Flora). I have noted that the majority of websites consulted also from other
sources, like NGOs or Foundations, refer to the very same number: worldwide tiger population = 3200.
The tiger or Panthera Tigris has 9 subspecies: the
Amur (Siberian), the Bengal, the Indochinese, the Malayan, the South-China, the
Sumatran, the Bali, the Caspian and the Javan. A good description of each
species has been done by Tigers in
Crisis, an initiative of Craig Kasnoff. Many
photos are to be found in the Cal Photo
data base.
The
geographical distribution can easily be induced by the name of the subspecies:
from central and southwest Asian to the Indonesian archipielago passing through
large areas in South East and Eastern Asia. A Tiger ranger map may be found in
the WWF
website devoted to wildlife trade.
Out of these
9 subespecies, the last three are considered to be extinct respectively since
1937, 1968 and 1980. The other six have long been considered endangered species according to the IUCN Red List
of Threatened Species. This list appears to be the most
comprehensive tool on the conservation status of plant and animal species since
1994. It seems that the list is updated regularly, thus for more exhaustive
information it is recommended to visit the website of the List. I particularly
found very helpful the WWF
chart.
The species
is also included in Appendix I of the CITES Convention. This basically means
that the species is threatened with extinction. The import/export of
any tiger, dead or alive, including spare parts and derivatives is only
permitted in exceptional circumstances, and commercial trade is not one of
them. In the last 5 years only 6 tigers have been legally exported from
Uzbekistan for captive breeding purposes. In the future there will be a
dedicated post on the functioning of CITES, the international agreement setting
the framework for the trade in endangered species of wildlife and flora with
the aim to ensure their survival.
Estimates of
the Tiger populations in protected source sites total 2,154 Tigers (Walston et al. 2010). Always following
this source that can be found as a reference in different publications, the
range goes from 17 tigers in Laos to 970 in India. Over the last 20 years there
has been a reduction in population of around 50% (Dinerstein et al. 2007, Walston et al. 2010) and it seems that the
decreasing trend will continue in the future.
