The interfluvial area between the Kolik-Egan and Sabun of the west Siberian lowland is a zone of raised string bogs covering 12,885 square kilometres (4,975 sq mi). It is a status B Ramsar wetland, nominated for designation as a Wetland of International Importance in 2000. Martens are found throughout the Sabun River valley, as well as sables and kidas, crosses between sables and martens.
In the early 1940s the inhabitants of the upper reaches of the Tolka River, 500 kilometres (310 mi) to the north, were resettled by the Soviet authorities in the Sabun River basin after their shamans had been arrested and executed. They brought their reindeer with them, but the reindeer could not adapt and many died. The people of the community were unable to find food in the new environment, and some starved. They were allowed to return to the Tolka River after the war.
