Abstract

In spite of silver fir (Abies alba Mill.) historical importance for forestry management in the Czech Republic, this species shares currently mere 1.1% in the Czech forests due to several reasons such as biotic agents, air-pollution, game damage, inappropriate silvicultural systems etc. According to frequent calamities in dominant spruce monocultures, silver fir has been planted increasingly to establish more diverse and structured stands in last decades. These new stands with silver fir should be also adequately thinned. We see, however, a lack of experience with this silvicultural measure in practice nowadays. The article brings review of results and knowledge about thinning of silver fir stands in the Czech Republic and also from abroad where similar conditions can be expected. It is obvious that silver fir requires different approach to thinning compared to other conifers. We summarised knowledge about measures applied in both fir monocultures and mixtures from young phase of regeneration (artificial or natural) to final thinning in mature stands. Recommendations for pruning and for stands with postponed thinning are also included.
