What was the other name for the extinct tiger subspecies, which inhabited the sparse forests and riverine corridors west and south of the Caspian Sea, from Turkey, Mesopotamia, Iran and the Caucasus, that has a project reestablishing populations of the Siberian tiger by introducing them as replacements to the extinct tiger?
Siberian Tiger Introduction Project The Siberian Tiger Introduction Project involves reestablishing populations of the Siberian tiger ("Panthera tigris altaica)", also known as the Amur tiger, in their former range and also expanding their range by introducing them as replacements of their genetically similar relative, the extinct Caspian tiger ("Panthera tigris virgata") which inhabited Central and Western Asia. Currently, the Siberian tiger inhabits the cold mountains of the Russian Far East and northern China.
Khanates of the Caucasus The Khanates of the Caucasus, or Azerbaijani khanates or Persian khanates, were various principalities established by Persia (Iran) on their territories in the Caucasus (modern-day Azerbaijan Republic, Armenia, Georgia and Dagestan) from the late Safavid to the Qajar dynasty. The Khanates were mostly ruled by Khans of Turkic (Azeri) origin and were vassals and subjects of the Iranian shah (King). Persia permanently lost a part of these khanates to Russia as a result of the Russo-Persian Wars in the course of the 19th century, while the others were absorbed into Persia.
