Ulaanbaatar, November 13, 2025 /MONTSAME/. A 600-hectare area of degraded land in the Tsagaan Zuriin River area, located in Khuder soum, Selenge aimag, has undergone successful ecological rehabilitation, reversing years of damage caused by irresponsible mining practices. The scale of restoration is equivalent to planting 12 million trees, marking a major milestone in ecological recovery. The revitalized land has been formally transferred to the Selenge Aimag Department of Environmental Protection for ongoing stewardship.
The rehabilitation initiative was financed by Oyu Tolgoi LLC in alignment with the policy framework of the Ministry of Environment and Climate Change, and executed by local contractors in Selenge aimag. Jinjii Mining Company restored 400 hectares, while Bugant Nandin Company rehabilitated 200 hectares – both returning the natural soil to its original state. According to Oyu Tolgoi, this represents a significant step toward the broader effort to restore the Tsagaan Zuriin River ecosystem.
Before this initiative, Oyu
Tolgoi LLC had already restored 400 hectares in the Yalba Valley of Yeroo soum,
Selenge aimag, and 215 hectares in Sharyn Gol soum, Darkhan-Uul aimag. These
efforts are part of the company’s “100 Million Trees for the Future” campaign,
which aligns with Mongolia’s national “Billions of Trees” National Movement. Through
this initiative, Oyu Tolgoi has committed to rehabilitating all areas in Selenge
aimag affected by abandoned and environmentally harmful mining activities by
2027. Over the past three years, Oyu Tolgoi has planted a total of 35.1 million
trees through a combination of initiatives and verified offset programs.
