Bauer, Norbert: Open sandy grasslands of the Bakony region

and a sketch of succession of the sandy steppe in the region of the Danube-Tisza Interfluve (Duna-Tisza köze). There is an abundant literature discussing the vegetation of sandy areas in the Carpathian Basin. The publications of SOÓ (1930), MAGYAR (1933), HARGITAI (1940), ZSOLT (1943), BOROS (1953), KÁRPÁTI and KÁRPÁTI (1954), PÓCS (1954), and ZÓLYOMI (1958) describe the sandy grasslands of Kiskunság and the Pest Plain in great detail. STURC (1997) summarises the accumulated knowledge of the sandy flora and vegetation in the surroundings of Szabadka (Subotica), by comparing these to other sandy areas such as Kiskunság and Deliblát in many respects. Of these areas, BORBÁS (1886), BERNÁTSKY ( 1910) and WAGNER ( 1914) give a clear picture of the sandy steppe vegetation cover, which then was further elaborated by STEPANOVIC-VESELICIC (1953) and BUTORAC (1999). The detailed works of RAPAICS (1916, 1925fc), BOROS (1929), SOÓ (1933a, 1939), ASZÓD (1936) describe the sandy vegetation of Nyírség. BOROS (1944) draws the attention to the sandy area dominated by beany vegetation types of the "Székelyföld" (Szeklerland) area of Transylvania. POLGÁR (1912, 1941) provides the first account of the sandy vegetation of the Little Hungarian Plain (Kisalföld), followed by BORHIDI (1956) on the grassland associations of the region and the margin areas. BORBÁS (1900) and SOÓ (1933Z?) describe the sandy vegetation of areas south of Lake Balaton, BORHIDI (1958, 1959) discusses the sandy vegetation and phytogeography of southern Transdanubia (mainly Inner Somogy (Belső-Somogy)), while TIHANYI (1965) presents his observations of the sandy vegetation of Darány. LÁJER (2004) gave a detailed study of the current status of the South Transdanubian Teesdalia nudicaulis stands and Corynephorus grasslands. Recently LÁJER (2006) has overviewed the Hungarian sandy grasslands dominated by Corynephorus canescens and presented three relevés of the Bakony region. Because of his significant work in the exploration of the wider region's sandy vegetation, KLIKA (1934) is worth mentioning, who published the samples of "Festuca vaginata-Dianthus serotinus''' association examined along the River Morava, from where subsequently KRIPPEL (1954) published the Thymo angustifolii-Corynephoretum association. Presently, intensive botanical researches are being carried out on significant sandy areas of Hungary, mainly in the region of the Danube-Tisza Interfluve and in the Nyírség. These investigations (FEKETE et al. 1988, FEKETE 1992, KÖRMÖCZI 1989, KÖRMÖCZI and BALOGH 1990, MATUS and TÓTHMÉRÉSZ 1990, MATUS 1996, KERTÉSZ etal. 1993, MARGÓCZI 1995, BAGI 1997, 2000, GOSZ et al. 1999, BARTHA 2000,2001, BARTHA et al. 2003, CSECSERITS and RÉDEI2001) have significantly improved our knowledge and understanding of the succession of otherwise well-known vegetation units (BORBÁS 1884, RAPAICS 1925b, SOÓ 1930,
