More than 200 fires are burning across an area of 1.1 million hectares of the country, almost 1 million of which cover remote forest areas in Russia’s republic of Sakha and the Krasnoyarsk region, both in Siberia. The wildfires exceeded 3 million hectares, an area the size of Belgium, at their peak last month.

Russia’s forest authority estimates that forest fires across Siberia and other regions have cost approximately 7 billion rubles ($106 million) so far this year, the state-run RIA Novosti news agency has reported.

“It’s impossible to be more specific because we need to survey the areas where the fire has passed,” the Federal Forestry Agency’s acting chief Mikhail Klinov was quoted as saying Wednesday.

Grigory Kuksin, the head of Greenpeace Russia’s firefighting program, said the 7 billion ruble estimate doesn’t account for the damage done to soil, air, wildlife and human health.

“This figure is to reassure people and doesn’t reflect the full extent of the damage … The real cost is at an exponentially greater magnitude,” Kuksin told The Moscow Times.

Activists and environmentalists have decried the authorities' slow response to this summer’s wildfires. In Moscow, demonstrators rallied for the Krasnoyarsk region’s governor to resign after he called fighting the fires “pointless” and “economically unprofitable.”

Government auditors estimate that wildfires have caused 68.9 billion rubles ($1 billion) worth of damage over the past three years.
