ABSTRACT

This study showed that biomass of underbrush occurring in stands of a simple structure is significantly greater than biomass of underbrush in stands of a complex structure. A great spatial variation of underbrush occurrence is probably the cause of difficulties in determination of its relationship with stand characteristics. In stands growing on sites of mixed coniferous and mixed deciduous forests the degree of site moisture determines the quantity of biomass of the underbrush layer. Generally in Scots pine stands biomass of underbrush decreases with increase of stand density. In the Niepołomice Forest the total biomass of the underbrush layer in stands above 10 years of age, occupying the area of 9 459 (ha), is 20 705 tons, and it was estimated with the standard error ±1 296 tons.

Key words: underbrush, biomass, stand characteristics.
