Sasan Gir is 72 km from Somnath. In the 19th century, the rulers of Indian princely states used to invite the British colonists for hunting expeditions. At the end of the 19th century, only about a dozen Asiatic lions were left in India, all of them in the Gir Forest, which was part of the Nawab of Junagarh's private hunting grounds. British viceroys brought the drastic decline of the lion population in Gir to the attention of the Nawab of Junagadh, who established the sanctuary. Today, it is the only area in Asia where Asiatic lions occur and is considered one of the most important protected areas in Asia because of its biodiversity. The Gir ecosystem with its diverse flora and fauna is protected as a result of the efforts of the government forest department, wildlife activists and NGOs. It is now considered the jewel of Gujarat's ecological resources.
