An outline of biocenotic significance of the studied insect taxa and possibilities to use them as bioindicators of changes in woodland ecosystems resulting from economic activities are presented. Puszcza Bukowa forest (NW Poland) is potentially unusually valuable as a refuge area for zoocenoses associated with forests of atlantic climate, unique in Poland. The studied insect associations are strongly affected, both with respect to their species composition and population structure of some component species. The degradation is most markedly expressed as reduced biodiversity. The main resons for this result from economic activity. An array of actions and abandoning some ingerence (at least in areas under reserve protection) are necessary to inhibit degradation processes in the ecosystems of the Puszcza Bukowa and to enable a natural reconstitution of its biocenoses.
