During its 39th session, the World Heritage Committee adopted a decision on minor boundary modification of Lena Pillars property at the expense of the section of the Sinyaya River basin, considerable in terms of area (115,000 ha).

On July 3, as part of the 39th session of UNESCO World Heritage Committee held in Bonn, they considered a matter on the inscription of a transnational Russian–Mongolian nomination The Landscapes of Dauria on the World Heritage List.

At the 39th session of the World Heritage Committee held in Bonn they adopted the decisions on the state of conservation of six Russian natural properties: Volcanoes of Kamchatka, Golden Mountains of Altai, Lake Baikal, Virgin Komi Forests, Lena Pillars and Wrangel Island.

The documents related to minor boundary modification of Lena Pillars property, being inscribed on the World Heritage List in 2012, have been forwarded to the World Heritage Centre. The documents justify the necessity of including the section of the Sinyaya River basin, a left bank tributary of the Lena River, as part of the existing World Heritage property, which will significantly contribute to the Outstanding Universal Value of the property according to criterion viii.

The Natural Heritage Protection Fund and WWF Canada have developed a scientific justification for Outstanding Universal Value of the World Heritage property Last Ice Area. The developed materials are planned to be used in the course of preparation of the joint transnational Canada–Denmark nomination bearing the same name for inscription of the property on the World Heritage List.
