Explanation:

Artificial and natural regeneration is reasonable under specific habitat, climatic and stand conditions and should be applied provided it serves to increase the relative sustainability of forest ecosystems.

In 2002, natural regeneration accounted for 7.9% of all restocking (reforestations and afforestations) in Poland. To obtain a young generation of trees from self-seeding a number of factors should be taken into consideration. Under the climatic and soil conditions of Poland, as well as high population pressure and the resultant potential species composition of stands, regeneration by planting is and should be the main form of forest restitution. Stand regeneration by planting, established in accordance with the ecosystem’s demands, imitates natural regeneration after major disturbances and over a longer time span ensures the sustainability and balanced development of forests in the right temporal and spatial order.

Natural regeneration should be applied where the probability of obtaining a young generation of trees from self-seeding and stable stands in the future is high. Unfortunately, natural regeneration that will ensure forest sustainability and species diversity on the most of the territory of Poland is not possible, mainly because of the habitat structure with predominant pine forests, the domination of species naturally arising after major disturbances, and low annual precipitation with frequent droughts during the germination period. These factors determine the choice of the clear-cut or partial cutting systems and associated regeneration by planting or by limited strictly controlled self-seeding.
