Experiment in transforming native birch forests into Siberian pine forests

The article presents materials of long-term work on converting soft-leaved low-value forests into Siberian pine stands on the Berezovsko-Lavrovskaya dacha’s territory in the Tomsk region. The study has a great potential for planning forestry systems in Siberian pine’ seeds (nuts) producing areas adjacent to populated areas. The results show that when implementing measures of transformation soft-leaved forests into pine plantations, it is necessary to apply an integrated approach combining the care of formed Siberian pine plantations and its crops, and the fire-fighting system organization.
