Abstract

Transformation of cenomorphs of grass-dwarf-shrub layer of forest phytocenoses of Zhytomyr Polissya after surface fires was analyzed in forest ecological types A2, A3, B2, B3, B4, C2. It was shown that the cenomorph spectrum of grass-dwarf-shrub layer after surface fires essentially transforms. In all investigated forest ecological types after forest fires number of cenomorphs increased.
It was made a conclusion that the general regularity after surface fires in this layer was an essential decreasing of part of typical forest species — sylvants and sylvants-pratants in species composition of the layer, and increasing of relative part of pratants, entering of ruderants.
