CAR-ES and the SNS-120 project organized a seminar and workshop in Helsinki, 31 October – 2 November, 2018. The main aims were to examine the main results of the SNS-120 project as well as novel research on the topic, discuss utilization of wood ash in forests and how it is regulated in different countries, and update the status of the work done in CAR-ES activities.

A joint CAR-ES and NB Nord meeting was held at Skogforsk, Uppsala, in February 21 – 22, 2018. The purpose of the meeting was to initiate new Nordic/Baltic research and to facilitate already existing collaborations between the two CARs that share an interest in sustainable forest management.

CAR-ES III workshop and network meeting “Understanding Forest Management for Enhanced Environmental Services: Soil carbon dynamics and functional biodiversity” was held at the University of Tartu, June 30th 2017, back-to-back with the Woody Root 7 Symposium ( ).

The meeting aimed at getting an overview of previous and ongoing studies on soil functional biodiversity and relationships with soil carbon accumulation and loss in forests of the Nordic-Baltic region,  in general as well as in relation to various forest management practices. Contact persons: O. Janne Kjønaas (NIBIO, Norway) and Ivika Ostonen (University of Tartu, Estonia)

CAR-ES 2011-2015 final conference:

Managing Forests to Promote Environmental Services: Climate change adaptation and mitigation, water protection, biodiversity conservation, and soil quality maintenance.

Carbon sequestration, water protection and biodiversity are key environmental services provided by the Nordic and Baltic forests, and each of them are linked to soil properties and quality. Various types of forest management have different effects on these services, and knowledge on how the forest management can help maintain and enhance them is crucial to sound decision making in the forest sector and in policy development.

The conference was arranged to properly round-off the activities of the SNS funded CAR-ES network for the 2011-2015 period. All researchers working with these topics were invited to present their work, present state-of-the-art, and jointly identify knowledge gaps to be addressed in the future.

The conference was successfully held in Copenhagen, 3-5 November 2015, with about 50 participants from especially the Nordic and Baltic countries, but with also Germany, Great Britain and United States being represented. Several PhD-students participate and presented their work.
