Author develops the title thesis. The forests have an undisputed bio-therapeutic effect on the human organism with the oak groves, hail and marshy meadows leading the way in psychological healing. Both summer and winter forest have calming effect. Other examples - in the article.
The role of dead trees in the forest has been underestimated or misinterpreted for many years. Fallen and lying in the forest, they have been treated as wastage and a habitat for such organisms as insects, arachnids, fungi and bacteria — a source of diseases and a threat to healthy trees. That is why they were removed from the forest, which prevented on-site decomposition of organic matter and recycling of nutrient elements. Due to severe changes in forests, degradation of habitats and degeneration of tree stands, the reasons for this adverse phenomenon have been sought. The article deals with the role dead trees have in the extremely complex forest organism.

Canadian forests play an immense role in shaping the global climate. Forest resource management is one of the most important economic sectors in Quebec, the second largest Canadian province. 86 per cent of the forest resources are public. Legal regulations, especially the Forest Act, match the principles of UN environmental regulations. Fire is the largest threat to Quebec forests. Forty million dollars are spent on fire protection, 85 per cent of which is spent on prevention, fire detection, etc.
Opening new mines, deeper operations and the constant spread of mining activity to new terrain is associated with more or less extensive disturbance of natural water regimes. This is manifested in the drying of farm wells and ponds, reduced flow in water courses and, sometimes even their complete disappearance with extreme drying of orogen and soils. Typical symptoms of such disturbances are hydrological and soil changes and alteration of habitats. A very large disturbance of this kind is subsidence depression zone surrounding the Bełchatów brown coal strip mine. The authors discuss its effects on soil and habitat conditions, using two forest districts as examples.
