The basics of sustainable forest management in forest promotional complexes
Biodiversity ; Concept ; Dead wood ; Decision making process ; Ecosystem ; Environmental management ; Forest ; Forestry ; Sustainable development
The intent to create Forest Promotional Complex (FPC) was introducing a new quality to Polish forestry – by taking into account social preference for forests, by embracing local community needs, by compromising forest production with nature
protection and to introduce the rules of sustainable and balanced forest development. Main subject of this study is a dead wood and its ecological functions in managed forests and chosen FPC reserves. The problem of naturalization or ecologisation of forest

an evaluation of DDW resources in the 3 Forest Promotional Complexes of Puszcza Białowieska, Bory Lubuskie, Bory Tucholskie. An analysis of the correlations is included. The third and final part offers a critical look at the implementation of the recommendations
made 10 years ago by the authors of the project. These were recommendations for, what were at that time, new principles of handling DDW in Polish forests.

content), and selected characteristics of vegetation (species richness, herb layer biomass, moss layer biomass) in one type of forest community, namely, pine forests of the Vaccinio-Piceetea class. The study area covers the major part of the European
domain of pine forests, from 70.15°N (Norway) to 50.35°N (Poland) and from 12.02°E (Sweden) to 33.6°E (Russia). The results clearly point to the simultaneous effect of several different mechanisms shaping the structure of soil and the forest floor.
