Abstract: Recent changes in species composition and abundance in seven plant communities characteristic of Central-European, Sub-Atlantic and Alpine belts of the Central Apennines (oak and beech forest, dwarf-shrubland, high-mountain grassland and alpine tundra) were analysed on the basis of 30 permanent plots. Plots, 100–300 m2 in area, were selected in the Velino Mts. National Reserve and the Gran Sasso and Laga Mts. National Park, at altitudes from 1,000 to 2,300 m a.s.I. For each plot, a phytosociological relevé was collected (according to the Braun-Blanquet approach) in 1993 and repeated 6 and 8 years later, in 1999 and 2001. In some cases, a relevé collected seven years before (in 1986) was also available. A comparative analysis of changes in species composition, life forms, life strategies and morpho-functional types allowed us to recognise dynamical processes (fluctuation, secondary succession and degeneration) and an increase in drought- and stress-tolerant species, in some cases probably linked to a general process of climate change.
