Glebowe kopce posówkowe – geneza, aktualny stan i możliwości ich zagospodarowania w drzewostanach sosnowych na przykładzie Nadleśnictwa Tuchola

Abstract

Soil mounds with pine beauty pupae, piled on in mature pine stands planted from artificial forest regeneration on clean cut forest area after pine beauty gradation in in the twenties and thirties of the last century, play an important economic and ecological role in some forest complexes of Bory Tucholskie and the Puszcza Notecka. A characteristic feature of mechanical control of pine beauty was crafting mounds of soil (which varied in thickness) from material derived from the levels of organic and humus-mineral soils. The issue of the rational use of soil mounds with pine beauty in the period of contemporary forest clearing requires a deep analysis and taking an appropriate position. The soil cover after gradation stands is transformed, often to a significant extent, in a way of morphological structure and biophysicochemical properties of soils surface genetic levels.
