SAVE THE SAIGA ANTELOPES
By: Surabhi Das
Saiga Antelopes that once used to be found in numbers of over a million are now critically endangered with a population of only 50,000
- sexually mature at 7 months
- 1 or 2 offspring (twinning rates common)
- 8 - 10 year life span
The Saiga antelope are hunted for their meat & horns. They are believed to have medicinal properties in China.
The economic downfall in the 1970s of the USSR, increased the hunting of the Saiga antelope and provided a way for the common man to make an income.
The Saiga antelope compete with other species for grazing grounds; this is an example of inter specific competition. Also much of their natural habitat is being claimed for agricultural use.

In the month of May 2015, a unexplained epidemic wiped out almost half of the Saiga population. Similar die offs have occurred in 1980's and in 2010.
