Reforestation after disturbances in planted Norway spruce stands – Influence of silvicultural techniques on seedlings field performance

Reforestation after forest decline can be difficult. Selection of silvicultural techniques used during reforestation is crucial for good reforestation outcome, also lowering costs of labour and reproductive material used. Climate change will add to complexity of silvicultural interventions. Present and predicted disturbance regime points to the increase of areas for reforestation in Europe, thus creating the need for update of knowledge on regeneration methods and seedling types used. Newly gained knowledge acts as a background for national forestry and nursery programmes. Study examines area after bark beetles attack and wind throw in planted Norway spruce stand after it was reforestated by seeding and planting of European beech and Silver fir at European beech and Silver fir dominated forest area (placed on the crossroads of Central and Southeast Europe). Analysed data track seedlings field performance (height, basal diameter, quality indices and height increment) during three consecutive years (2010–2013) and again eight year after canopy loss (2017). In addition, we discuss the issues of different silvicultural interventions (direct seeding, planting of different type of seedlings, intensities of canopy loss, site preparation techniques) during reforestation of area after disturbances in hilly and mountain areas. Review includes management and legislative legacy as well as state of the art of contemporary silvicuture related to reforestation practices of Southeast Europe, with Croatia as a case study.
