The knowledge of natural processes and the control of forest environment allow the foresters for an early diagnosis of dangers that may have a negative impact on the condition of forest. Every year, the foresters take actions to preserve forest life and increase its natural resistance to damage-causing factors.
The dangers are divided into three groups:
- biotic - caused by excessively developed populations of harmful insects, pathogenic fungi or herbivorous mammals;
- abiotic - extreme atmospheric phenomena (e.g. strong winds, snow, heavy rains, high and low temperatures);
- anthropogenic – caused by man (e.g. fires, industrial pollution, littering the forest).
Forest protection requires prevention. That's the basic rule. It encompasses a set of actions, designed to increase the resistance of forest to pests and pathogenic factor. The model actions are to aim at upholding and restoring nature-like forest ecosystems. Only the most nature-like ecologic conditions can ensure the sustainability and optimal productivity of forests.
