ABSTRACT
Forests cover almost one third of the earth and their environmental and economic value is extremely high. Forest ecosystems are one of the most important sources of renewable resources, playing an exceptional role in the global turnover of materials and energy. Forests provide very important habitats and their role in biodiversity protection is very important. The environmental role of forests has especially increased along with the increase in environmental pollution. Forests can be considered as one of the main carbon dioxide sinks and help to absorb some air pollutants. The exceptional environmental and economical value of forests and their sensitivity to the environmental pollution requires us to consider forests as one of the most appropriate objects of environmental monitoring and assessment.
