Historically, the Asian Lion had a distribution that varied from Greece, Syria, Iran, Pakistan to India. They are currently only found in the Gir area of Gujarat, India, making them vulnerable to extinction due to unpredictable events, such as an epidemic or a major forest fire. The Lion population disperses outside the protected area, implying conflicts with humans, which can lead to the poaching of Lions.
In the Gir forest there are only 350 Lions, with only 175 mature adults.
The fact that Asian Lions are restricted to a small and isolated area, makes it essential for the species' survival, that a healthy and growing population is maintained in Zoos.
