The Siberian tiger (Panthera tigris altaica),
also known as the Amur tiger, is a tiger subspecies inhabiting mainly
the Sikhote Alin mountain region with a small population in southwest Primorye
Province in the Russian Far East. In 2005, there were 331–393 adult and
subadult Amur 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. By 2015, the Siberian
tiger population has increased to 480–540 individuals in the Russian Far East,
including 100 cubs. A more detailed census revealed a total population of 562
wild Siberian tigers in Russia.
The Siberian tiger and Bengal tiger subspecies rank
among the biggest living cats. A comparison of data on body weights of
Siberian tigers indicates that up to the first half of the 20th century both
males and females were on average heavier than post-1970 ones. Today's wild
Siberian tigers are lighter than Bengal tigers. Their reduced weight as
compared to historical Siberian tigers may be due to a combination of causes:
when captured, they were usually sick or injured and involved in a conflict
situation with people.
