Tiger Demographic

[Dr Panthera]

@Shardul The half of tigers reside in unprotected area statement is used by Karanth who is quite critical of the census results as you know, it is not an assumption but more of a reasonable concern and he of all people affirmed again that doubling tiger numbers by 2022 is not going to happen.
Poachers will never be discouraged by awareness, education, or anything other than legal consequences, they would annihilate all tigers given half a chance.
The bengal tiger Panthera tigris tigris is classified EN (endangered ) on the IUCN list , a taxon can still be in that category even with 2500 mature individuals if they meet a set of criteria related to :
A_ Decline in population size
B- Shrinking of geographic range
C-Population is less than 2500 mature individuals and some other criteria are met.
D-Population is less 250 mature individuals regardless of any other factors.
E-20% probability of extinction in the wild within 20 years or 100 % in 100 years if current trends continue.
Even in tigers "heaven" in the indian subcontinent the tiger is still endangered.
We can take heart that at least the numbers are rebounding in some areas and it is doing much better than other tiger populations. Reply
