Özet:

Wood production and maintenance of forests are carried out taking into account sustainability and silvicultural needs. For the production of quality logs, forest maintenances are made for this purpose until the end of the rotation period. Abnormal formations and growth patterns outside this purpose are eliminated during maintenance and cannot reach the industry in their natural forms. However, many furniture and decorative items with high economic value in the furniture industry can be obtained from trees that show abnormal growth. The aim of this study is to determine the abnormal formations in some tree species in our forests, to examine the sector that processes such wood materials, to reveal the contribution it will provide to the economy and to raise awareness. For this purpose, trees showing growth abnormalities were sampled on the basis of species in the study conducted in Bursa and İnegöl Forestry Management Directorates and Uludağ National Park. Wood types and their properties offered for sale in Bursa and İnegöl Forestry Directorates (OİM) were examined. Moreover, the situation of the sector was evaluated with the survey studies conducted with such massive woodworking enterprises. The design products produced as a result of the processing of solid wood were investigated and the cost and sales averages were compared. As a result of the study, it was observed that the growth anomalies differed according to the tree species and the highest abnormality was observed in plane trees (Platanus orientalis L.) and least in black pine (Pinus nigra Arnold.). It has been determined that these formations can be transformed into products with very high added value when evaluated by the sector.
