Forestry trend reclamation of worked out clay quarries efficiency in the Middle Ural taiga forest region

The article touches upon the analysis of creating artificial pine peantations on worked brick clay quarries in the conditions of the Middle Ural taiga forest region. The study is based on the method of trial plots, which were laid in plantations of different ages. Of was experimentally established that the reclamation forestry trend is effective and ensures the return of the coniferous to the economic circulation of the worked out brick clay quarries. By 55 years old, artificial pine stands created on the territory of worked out brick clay quarries have a stock of stem wood of 345 m3/ha and are characterized by the second bonitet class. On other words, as a result of reclamation work, high-productive artificial pine plantations are formed on the territory of worked out brick clay quarries. Tables of the growth progressing of the artificial pine forests, compiled on the basis of the conducted studies, form the basis for forestry management on reclaimed lands.
