  1. Satellite monitoring:Yugyd va National Park,Alkesvozhskiy block on gold2009-2011 Transparent World, non-for-profit partnership http://new.transparentworld.ru

  2. Main changesdetected by using satellite data: • Consequences of geological prospecting at Nesterovskiy and Chudnoye subblocks of Alkesvozhskiy block on gold are obvious at satellite imagery since 2011, June • High volume of suspended matters eroded from Nesterovskiy subblock cause a great turbidity of Grubependity lake’s water • Anthropogenic transformation is taking place also outside of Nesterovskiy and Chudnoye subblocks (ex: new facilities on the road to Chudnoye subblock)
