If you look at historic modern tiger range map at last glacial maximum about 20000 yrs BC. Tigers definitely lived in Kathiawar peninsula indeed (gir forest).

but, again take a look at tiger range map few centuries ago...

There is natural extinction (somewhat humans also) of tigers due to arid climate and habitat change in Gir region.

But, there is tiger habitats still exists inside of Gujarat border regions which are not undergone much changes triangular to today's lion range.

Again, Tigers and Lions of India living in same eco-region i.e.., Gir - Kathiawar - Gwalior eco-region which includes aravali range's Aravali tigers (Ranth and sariska) and now extinct Vindhyachal tigers of "Gujarat".

The tiger's presence in Gujarat since past 30 yrs in those dang forests and other forest ranges like Mahisagar facing MP, Raj and Maha shows even man extirpated them, they are going to bounce back.

One thing is sure evolution is a process which never ends. If again, Gir is favorable to Tigers (as they are able to live in similar conditions like Rath and sariska) and if they can migrate and extend their range "NATURALLY". Then, we can't oppose their presence in gir.

Species if having growing population will extend their distribution range...
Like Jackals distributing outside their range in Europe...
Polar bears of Russia living outside their recent natural range due to climate change with brown bears and black bears which once being a brown bear left america's to arctic to evolve as polar bear due to the same climatic and environmental conditions.

In the same way, tigers which left or extinct in gir region may come again if it's natural conditions favor that migration and colonisation. That's natural and that's how nature work. Tigers may recolonize their "late Pleistocene range" if conditions favor similar to RANTH and SARISKA.

Quote:But, man made translocation of tigers to gir is opposable and against rules of IUCN introduction outside "recent" tiger historic range. It should happen naturally if possible. Hope you are understanding what I'm saying.
