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.

Ecological sites are the Romains of ecosystems that deserve protection and are of great importance for maintenance of biological diversity, f. ex. mid-forest water ponds, swamps, mosses and sites of rare plant, animal and mushroom species.
According to the register from 01.01.2002 there were 9 ecological lands on the area of Krosno Forest District of 29.94 ha. Adjustments and joining old lands and adding new ones resulted in seven ecological lands of much greater area: 50.19 ha. Four former lands were joined into "Great and Small Swamps of Gądków": Little Swamp of Gądków and Gądków Swamps I, II and III. Two new lands were founded: Ratnowskie Swamp and Crane Swamps. Currently 14 ecological lands exist. The 8th of them "Lake Moczydło Swamps" was established by the decision of Krosno Commune Council (24.08.2006). The following two, namely Ponds of River. Pliszka and Forest Sanctuary,were established in 2007. The following year witnessed the foundation of Skórzyn Sanctuary on the area of non-forest characteristic (6.01 ha). Radomicko Range and Pliszka River Range were authorised in 2009. The youngest of lands is the Devil's Pond near Radomicko of forest area of 2.41 ha.
