It supposedly repressed in the region of the "Osfenyves" compared to the earlier spread of Festuco-Corynephoretum, which is related to (1) the area having been declared protected (1954) and so grazing in the forest areas practically ceased, (2) destruction caused by the open bauxite mining operations in some parts of the "Osfenyves" - according to BARTHA (1999) on natural patches. In connection with the supposed secondary state of Corynephorus patches, it is important to mention that HARGITAI (1940) also expressed a similar opinion on the sandy grasslands of the region near Nagykőrös. In the area of the Danube-Tisza Interfluve he considers Corynephorus canescens as an indicator of the originally lime-rich, sandy, leached, nutrient-poor patches. According to him Festucetum vaginatae and the Festucetum vaginatae corynephoretosum canescentis (Festuceto-Corynephoretum) units mentioned in his article can be perfectly separated physiognomically, but he could not trace any important ecological or "sociological" differences. Corynephoretum thus can be deduced from Festucetum vaginatae, and he considered it the "weak species variant", which appears following soil destruction (the actual name of these grasslands in the area of the Danube-Tisza Interfluve: Achilleo ochroleucae-Corynephoretum (HARGITAI 1940) BORHIDI 1996). According to HARGITAI (1940) such a sharp borderline could not have been formed between the two units (in the Corynephorus stands there are continental, Ponto-Mediterranean and Mediterranean elements) because of the semiarid climate of Table 5 (continued) 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 Carlina vulgaris - - + - + -- -- -- -- -- + - + Crépis tectorum + - - + + + _____________ Poa compressa - + - + + + -- -- -- -- -- -- -Achillea collina - - - + + + -- -- -- -- -- -- -Moenchia mantica - - - + + Aira caryophyllea ----- + + -+ -- -- --
