Major threats

Density independed factor

A density-independent factor is any factor limiting the size of a population whose effect is not dependent on the number of individuals in the population. 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.

Density dependent factors

A Density dependent factors is any factor limiting the size of a population whose effect is dependent on the number of individuals in the population.When the USSR economic downfall occurred, the Saiga populations was fairly flourishing. People saw this population as a way to make profits in a difficult time. Saiga parts were highly in demand at different parts of the world and this caused supply (the population) to go down drastically over the years.

Carrying Capacity

Saiga antelopes have a carrying capacity of 2 MILLION!! With only a population of 50 000 now, the antelopes are CRITICALLY endangered.

Defense mechanisms

Saiga antelopes have horns to fend off predators, but male Saigas also use their horns to compete for females. This is an example of INTRASPECIFIC competition. Saigas are fast runners and their speed can reach upto 80 km per hour. Another advantage that Saigas have is that they can swim while their predators may not be able too.

Survivorship Curve

The Saiga antelope falls under the type 1 survivorship curve. Saigas have a high rate of juvenile survival and most individuals live beyond sexual maturity. Saigas have low fecundity with only 1 or two babies born at a time but parental care is high.


Saigas are listed on apendix II of the Convention on International Trade in Endangered Species (CITES) meaning that trades in this species are monitored closely. Hunting is banned throughout the region where Saigas are still present. Many non profit organizations are working towards making anti- poaching laws stronger.
