The Siberian tiger (Panthera tigris altaica) is a tiger subspecies of
northernmost distribution. It occurs in the Russian Far East, northeastern China
and northern Korea. Due to excessive logging, intensive hunting and scarcity of
prey animals, the numbers of Siberian tiger had become so small by the middle of
this century that it was listed int the International Red Data Book as the first
endangered tiger species. To save the animal from extinction, the zoos under the
coordination of Leipzig Zoo started captive breeding programmes. In 30 years notable
results were achieved. In the 1980s the captive population of Siberian tigers reached
1000 inividuals and the wild population was maintained at the level of 700 individuals.
The conservation actionas had stopped the decline the species. At
Tallinn Zoo the Amur tiger has been
breeding since 1971.
