The annual celebration of "Tiger Day" was held on Sunday in Vladivostok.

"Tiger Day," which has been celebrated in Vladivostok since 2000, has expanded to villages and towns throughout Primorsky Krai, Russia's most southeastern region, which contains the majority of the remaining Amur tiger habitat.

"Tiger Day" is the biggest eco-celebration in Russia's Far East. Citizens, students and representatives of many organizations wear orange clothing from head to toe and join the tiger parade that moves through the center of the city to show their concern about the tiger's future.

The Amur tiger, the largest of the six big cat sub-species that still exist, numbers only about 500 and lives in the forests of the Russian Far East near Vladivostok and in Northeastern China.

The event was organized by the Russian NGO Phoenix Fund, with support from the Primorsky authorities, the Vladivostok local government, WCS Russia, the World Wildlife Fund (WWF), the International Fund for Animal Welfare (IFAW), and the Far Eastern Development Fund "AzArt."
