GROWTH OF TREES USED IN REFORESTATION OF A NORTHERN SLOPE OF THE EXTERNAL SPOIL BANK OF THE "BEŁCHATÓW" BROWN COAL MINE
Marek Paj±k, Marcin Forgiel, Wojciech Krzaklewski
ABSTRACT
The purpose of this study was to assess the growth of tree species planted 20 years ago on a northern slope of the external spoil bank of the “Bełchatów” Brown Coal Mine. The results showed that black poplars and black locust were characterized by the highest mean volume of merchantable timber of a single tree. The lowest value of this characteristic was found for black alder. The ecological characteristics of tree species being introduced during reforestation of the postmining areas should be well adjusted to existing site conditions. In order to assess the value of individual tree species (in respect of their growth and productivity) for the reforestation of such areas the similar studies should also be undertaken in older stands growing in postindustrial grounds. Total results of such studies would make a prerequisite for formulation of general conclusions and recommendations for the reforestation projects.
Key words: forest reclamation, growth of trees, spoil bank, brown coal.
