MILDLY-DAMAGED FOREST AREAS IN BOREAL FORESTS OF THE WORLD. THE ORIGIN, DEVELOPMENT, IMPOTANCE AND PROBABLE FUTURE OF THE CONCEPT OF MILDLY-DAMAGED FOREST AREAS WITH REGARD TO BOREAL FORESTS

Abstract

The most important environmental goals at the global level, relating to forests, are conservation of biological diversity in the natural environment of its habitat and preservation of the environmental role (especially regarding the climate) of forests. Major forest areas, not fragmented by infrastructure and preserving the diversity of relationships between landscape elements, are of crucial importance for solution of both these problems. Since many decisions, concerning conservation and management, are taken at inter-regional and inter-state levels or within the framework of various international processes, it is important to have clear and uniform criteria for identification of such areas. The article deals with occurrence, development and current state of the most common concepts of allocation thereof – the concept of mildly-damaged forest areas, based on the use of remote sensing data, especially images from Landsat satellites. The article substantiates a necessity of further development and update of the concept of intact forest landscapes: unification of approaches to their identification near northern boundaries of forests, adjustment of approaches to registering impacts of forest fires in the context of global climate change and land-use practices, adaption to new public data of remote sensing of the Earth.
