Abstract. The study of litterfall was carried out in two different forest ecosystems: Vaccinio uliginosi-Betuletum pubescentis and Empetro nigri-Pinetum in the period between 2003-2005. The plant fall in the form of needles, leaves, shoots, sheeds, cones and barks provides to forest soils a lot of biogenic compounds. Much bigger annual mass of litterfall was found in Vaccinio uliginosi-Betuletum pubescentis and it was average 4,050 t/ha•year during research period. In the young wood Empetro nigri-Pinetum the litterafall was about 29% smaller (2,883 t/ha•year). The maximum intensity of litterfall occurred in autumn months and constituted about 60% of annual amount.

Key words: Pinus sylvestris, Betula pubescens.
