FOREST PROTECTION

The knowledge of the processes occurring in natural environment as well as regular control of the forest standing allow foresters to make an early diagnosis of any threats that might have a negative impact on a forest condition. Every year they perform activities to ensure forest continuity and to increase its natural resistance to stress factors.

Threats are divided into three groups:

* Biotic (for example insect pests, pathogenic fungi, folivorous mammals);

* Abiotic – dangerous natural phenomena (such as strong winds, hails, snow, deluge, high and low temperatures);


* Anthropogenic – caused by men (for example, fires, industrial pollution and forest littering).
