Immigration of plant species into abandoned vineyards and stone quarries


, : Immigration of plant species into abandoned vineyards and stone quarries. Acta Agronomica Hungarica 35(3-4): 315-326

The investigations were carried out on two special habitat types, completely influenced by man: (1) stone quarries and (2) vine-growing areas. Recently, after the cessation of human influences, the natural flora has been trying to return to its former sites. Analyses have been made in the following habitat types: (1) original vegetation, (2) rocky walls, (3) inner base, (4) bottom of the quarry. The vegetation of waste rocks was investigated separately. Phytosociological analyses have been made using the Braun-Blanquet scale. It is generally characteristic of both habitats that (1) in almost every case the species of weed associations can be found in younger communities; (2) if the species of the original associations are also found, their cover-abundance and position most differ from the original ones; (3) on the sites of analysis the chief tendencies of succession vary, leading to the formation of shrubs, forests and grassland, the latter being the most frequent.
