There is some good news regarding the Amur (Siberian) tiger.
According to the 2005 full range count in Russia
numbers are now about 500 Siberian tigers including about 100 cubs.
The count before this one in 1996 found about 470 including about 95 cubs.
This latest count was coordinated by WCS and involved almost 1000 people.
Siberian tigers have more advantages over the other sub-species of tigers,
comparing the last two counts numbers appear to be stable,
they also live in a 1000km continuous forest,
and the 500 individuals is a single population.
Apart from the survey counting the single population of 500 individuals,
the survey also counted the separate sub-population in
South-West Primorye but only 8 adults was counted unfortunately.
The main population is the largest single population of any tiger.
Another advantage is they have relatively few people
in that part of the world.
