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.

U very wrong..
Sorry bro siberian and bengal is one subspecies in IUCN now 
You ego cannot change IUCN understaind?

A study of scientists from the Leibniz Institute for Zoo and Wildlife Research in Berlin in 2015 (https://blogs.scientificamerican.com/tetrapod-zoology/the-tiger-subspecies-revised-2017/) suggested that tigers are only two subspecies: Mainland & Sunda.

But i haven't found any source if IUCN ever adopted that suggestion. Multiple sources like this (www.zmescience.com/different-tigers) says that it was rejected.
First confirm your claim. Do you have link of it being official?

'A REVISED TAXONOMY OF THE FELIDAE' (CAT-news, winter 2017, pp. 66-67)

The revised taxonomy of the felidae (see title) is based on two studies. One of these is 'Planning tiger recovery: Understanding intraspecific variation for effective conservation' (Wilting et al., 2015).

Although the article resulted in discussions, most authorities more or less agree with the recommendation to distinguish between two tiger subspecies only: mainland tigers (Panthera tigris tigris) and Indonesian tigers (Panthera tigris sondaica). The main reason is it facilitates conservation. Here's the link to the article:

http://advances.sciencemag.org/content/1/5/e1400175

As to the discussion on Indian and Amur tigers on this thread.

In the article mentioned above ('Planning tiger recovery: Understanding intraspecific variation for effective conservation'), regarding mainland tigers, a distinction is made between a northern (virgata and altaica) and a southern (amoyensis, corbetti and tigris) 'management unit'. 

Sondaica, therefore, is right in that most authorities today distinguish between two tiger subspecies only, but he omitted info on the northern and southern clades (regarding mainland tigers). 
 
Here's the link to 'A revised taxonomy of the felidae':

https://repository.si.edu/bitstream/handle/10088/32616/A_revised_Felidae_Taxonomy_CatNews.pdf?sequence=1&isAllowed=y

The special edition of CAT-news features in post 1,279. Comments in posts 1,285 - 1,286 - 1,289 - 1,291.

Although most agree with the proposal on two tiger subspecies only, the discussion on tiger subspecies hasn't been concluded.  

As to captive tigers. All zoos and facilities distinguish between Sumatran tigers, tigers from southeast Asia and Amur tigers.
