Forest management in State Forests is based on the Forest Management Plans created for the Forest District once per 10 years. They are prepared for the State Forests by specialised units, among others by The Bureau for Forest Management and Geodesy (BULiGL). The Forest Management Plans are approved by Environment Minister after consultations with society.
Preparation of the plan is always preceded by very precise inventory of stocks and assessment of the forest condition. The foresters specify such forest characteristics as: structure, formation, age, species composition, forest condition, soil and site conditions, etc.. In actions planned to be realised, the aims of forest management and functions the forests perform in arranged forest district, there are taken into account the following:
-maintaining the forests and their favourable influence on climate, air, water, soil, living conditions and human' health, and finally on nature balance.
-forests protection, especially protection of ecosystems constituting the natural elements of Polish nature or the forests particularly valuable due to:
• maintenance of nature diversity,
• maintenance of forest genetic resources,
• science needs,
-protection of soils and areas specially exposed to pollution or damages with significant social meaning,
-wood production on the basis of rational management and timber (raw material) and by-products of forest use.

The basic task of silviculture is preservation of existing forests (renewal), as well creating new ones (afforestation), with respecting nature conditions and natural processes. Within its range silviculture includes such issues as: collecting and storing tree seeds seeding, tree saplings production in the tree nursery, creation and nursery, as well as protection of forest cultivations and forest stands.
The forest, if it hadn't come into existence naturally, then it would be planted by the foresters. The saplings are cultivated in tree sapling nurseries. The cultivations are taken under nursing and protective treatments. They are to create optimum conditions for trees' growth of the most desirable ones in species composition of the growing forest stand. The last component of silviculture is forest old stand logging, due to make forest renewal possible in the optimum way for the growing tree species requirements.
