The studies were carried out in the region of two peaks (Mumlawski Wierch 1219 ma.s.l. and Szrenica Mt. 1362 m a.s.l.) in the Karkonosze Mts (south-western Poland). As a consequence of deforestation of the area studied, herb-layer vegetation has been altered. This consists in e.g. changes in quantitative proportions among components of the plants, gradual diminishing of dicotyledonous forest species, and an increase in participation of grasses (Deschampsia caespitosa and Calamagrostis villosa) in the communities. Range of these changes depends on how long ago an area was devoid of forest. However, the effects of such transformations are not irreversible. Within the spruce saplings overgrowing the deforested areas, regeneration of typically forest herb-layer vegetation has been observed.
