Struktura i dynamika opadu organicznego drzewostanu bukowego w roznych wariantach zyznosci siedliska w Ojcowskim Parku Narodowym w latach 1995 i 1996

The study presents the results on the dynamics and structure of the litter fall in the beech stand in two years (1995 - seed year and 1996 - barren year) overgrowing the northern slopes of the "Góra Chełmowa" located in Ojców National Park in two fertility variants. The total litter fall mass during the seed year was on average 4067.3 kg/1 ha and was different by 1260.15 kg from the results obtained during the following year. The greatest part of the litter fall are leaves, which make about 67.6% of the litter fall mass during the seed year and as much as 95.9% in the following year. The fertile habitat had a stimulating effect on the litter fall biomass production such as leaves, seeds, and seed cupules.
