SNS Growth and Yield Nordic biannual Conference, organized by LSFRI "Silava" took place in Latvia, LSFRI "Silava" on June 7–9, 2022. The Conference was organized as a combined in person and online event.
More than 30 scientists and doctoral students form Nordic and Baltic countries took part in this conference indoor sessions and field excursions, outdoor sessions at scientific research forests at Riga and Jelgava districts to discuss following topics:
- improvement of forest growing conditions,
- fast-growing trees and fast growing of trees,
- climate change and forest growth,
- benefits and risks of intensified forest management.
During the Conference, the scientists of LSFRI "Silava" presented several research projects:
