What I could find out from a more recent (and somewhat better written) 2015 article in the same venue:
Starting with the first East-West international conference “Fire in Ecosystems of Boreal Eurasia” (Goldammer & Furyaev 1996) and the Fire Research Campaign Asia-North (FIRESCAN) (FIRESCAN Science Team 1996, 2013) a dialogue with the forestry authorities of Russia (and the predecessor administration in the former Soviet Union, the State Forest Committee) has been initiated to replace the fire exclusion policy in the protected zone of the Russian Federation, Mongolia and Kazakhstan by an integrated fire management approach, which would include the use of natural fire and prescribed burning (Goldammer 2013a). Between 2008 and 2013 three major scientifictechnical events have taken place in Mongolia and Russia. The First International Central Asian Wildland Fire Conference “Wildland Fires in Natural Ecosystems of the Central Asian Region: Ecology and Management Implications” was held in Mongolia in 2008 and had significant impact on the review of past approaches in forest and fire management and on the ongoing process to formulate fire management policies in the region (Byambasuren & Goldammer 2013). In 2012 and 2013 two “International Fire Management Weeks” were organized in Krasnoyarsk Region, Russia, and resulted in the formulation of recommendations for adapting the fire management policy of the country with reference to the use of prescribed fire, allowing natural wildfires to burn within prescription and to take advantage of natural regeneration processes.1 The aspect of changing fire regimes as a consequence of climate change and land-use change has been addressed in a dedicated conference in 2013 and resulted in a strong warning to the governments of the region that the changes ahead may result in a threat by dangerous fires in future.
That seems to suggest that at least until 2013 prescribed burn was either not legal or not practiced in Russia. So has anything changed in that regard?
