There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Historically, Bengal did overlap its territory with both Chinese tiger and Indochinese tiger, so these two tiger groups were the ones who commonly interbred with Bengal. The Chinese tiger is quite interesting as they did overlap with Bengal in the Southwest China and with Amur in the North/Northeast China. Also, the Sumatran tiger is the natural hybrid between the Indochinese tiger and the Javan tiger which is a true crossover between two different tiger subspecies. If tigers wanna interbreed, then just let them be.
That's why I believe that the population of the Bengal tiger is the last hope for both Chinese tiger and Indochinese tiger. The survival for the Chinese tiger can only depend by breeding with Bengal, and the Indochinese tiger is also quite vulnerable. And the only hope to restore the Chinese tiger is to introduce the Bengal population. As for Bengal, they need to first re-boom their own population back to 10000, then we can talk about to borrow their gene pool for other tiger groups.
