Debreczy, Zs.: Fluctuating-dynamic equilibrium of photophil, xerophil rupicolous plant communities and scrub woods at the lower arid woodland limit

Fig. 4. Photophil, xerothermo-tolerant multicolour moss-lichen community (Mannio-Tortelletum inclinatae ) in open rupicolous (Chrysopogono-Caricetum humilis minuartietosum

) association maintained by a permanent humus erosion and litter deflation assisted by poikylohydric mosses preventing adhesion of litter. — Fig. 5. Grassland, open and closed rupicolous vegetation (Chrysopogono-Caricetum humilis minuartietosum and botriochloetosum) and the competing scrub wood (Cotino

—Quercetum) follow in their distribution the water loosing or watershed areas and the water gaining patches reflecting the micro-relief. A manna ash (Fraxinus ornus

) lacking the "Saum" and the necessary rendzina soil with good water retention ability, died in the drought 1983
