"The closure is an annual feature here. The sanctuary closes from June 15 till October for two reasons: one it is breeding time for a lot of species there and secondly it is not easily approachable during monsoon," the official said.
Gir, the last abode for Asiatic lions, is a dry deciduous forest and a major attraction for tourists.
Forests where a majority of the trees lose their foliage at the end of the typical growing season are called deciduous forests.
As many as 180 lion cubs were born under the special initiative of the Lion Breeding Programme which covers the park and its surrounding areas since its inception, the official said.
The major herbivores of Gir are Chital, Bluebull, Sambar, four-horned Antelope, Chinkara and Wild boar.
Blackbucks from the surrounding area are sometimes seen in the sanctuary, he said.
