This is caused, inter alia, by increasing intensity of forest and environmental damage as well as by the conflict of expectations for the use of forest resources. As a result, there is a problem of achieving the goals of sustainable development and adaptation of the forest ecosystems...
One of the tree species appearing after a decline of Norway spruce Picea abies (L.) H. Karst. in the Silesian Beskid Mountains is Silver Birch Betula pendula Roth. Therefore our study was aimed at evaluating this birch regeneration and the dynamics of changes resulting from experimental cutting. Measurements and inventories of trees were conducted on research plots located in a ten-year old birch...
The study assesses the effect of applied cuttings on the transformation of the species composition, structure and development of the forest towards selection forest type. The described control unit was established in 2000 in the Krucze Mts. (southern Poland) within the programme of silver fir restoration in the Sudety Mts. The working hypothesis was based on the advantageous effect of the selection...
The paper compares the proportion of damaged stands managed under group cutting system (group clear cutting and group shelterwood cutting) with the analogous stands where cuts had not been performed. The empirical material came from the database of the State Forests Information System and covered all forest districts located in Polish lowlands. To evaluate the group cutting a test of differences between...
