the siberian tiger ("panthera tigris tigris") is a tiger population in the russian far east and northeast china, and possibly north korea. it once ranged throughout the korean peninsula, north china, russian far east, and eastern mongolia. today, this population inhabits mainly the sikhote alin mountain region in southwest primorye province in the russian far east. in 2005, there were 331–393 adult and subadult siberian tigers in this region, with a breeding adult population of about 250 individuals. the population had been stable for more than a decade due to intensive conservation efforts, but partial surveys conducted after 2005 indicate that the russian tiger population was declining. an initial census held in 2015 indicated that the siberian tiger population had increased to 480–540 individuals in the russian far east, including 100 cubs. this was followed up by a more detailed census which revealed there was a total population of 562 wild siberian tigers in russia. as of 2014, about 35 individuals were estimated to range in the international border area between russia and china.

in 2005, a group of russian, american and indian zoologists published an analysis of historical and contemporary data on body weights of wild and captive tigers, both female and male across all subspecies. the data used include weights of tigers that were older than 35 months and measured in the presence of authors. their comparison with historical data indicates that up to the first half of the 20th century both male and female siberian tigers were on average heavier than post-1970 ones. the average historical wild male siberian tiger weighed and the female ; the contemporary wild male siberian tiger weighs on average with an asymptotic limit being ; a wild female weighs on average. historical siberian tigers and bengal tigers were the largest ones, whereas contemporary siberian tigers are on average lighter than bengal tigers. the reduction of the body weight of today's siberian tigers may be explained by concurrent causes, namely the reduced abundance of prey due to illegal hunting and that the individuals were usually sick or injured and captured in a conflict situation with people.
