Název v původním jazyce

Vegetation changes in beech and spruce stands in the Orlické hory Mts in 1951-2001

Popis výsledku v původním jazyce

Plant cenological surveys on the basis of Braun-Blanquet´s seven-point scale were made on 34 research plots in beech and spruce stands in the Orlické Mts 1951-2001. The acquired data were processed not only by traditional plant coenological methods but also by numerical analyses. The results document marked changes that occurred in species-rich spruce communities as well as in species-poorer communities of the associations. The developmental trend of these communities in 1971-1991 converged on types very poor in species. The period 1991-2001 was characterised by a marked increase in the number of species. An increase in coverage and number of tree species seedlings was very high after the productive seed years 1992 and 1995. The acceleration of changesin beech stands in 1971-1991 led to a species number diminution in herb-rich types and/or to their transition to species-poorer acidophilous types.
