Szerdahelyi, Tibor, Penksza, Károly, Dobolyi, Konstantin Z., Szollát, György, Kapocsi, Judit; Figeczky, Gábor: Vegetation and point-mapping survey in the strictly protected areas of the landscape protection area of the Pilis Mts (Hungary)

toration of the original natural vegetation would be desirable (to prevent the artificial transformation of mountain meadows, careful and gradual reconstruction of the stands full of ash trees). The flora of the Pilis Mts, especially the southern parts close to Budapest, were studied by several noted botanists during the 18th—20th centuries. There are some plants from the Pilis Mts even in the KITAIBEL herbarium (JÁVORKA 19261936). SADLER (1825, 1840) made detailed botanical investigations in the region. KERNER (1857) gave an overview of the Pilis Mts, too. The studies of BORBÁS (1872, 1879) were concentrated on the parts of the mountains belonging to Pest county. Floristical data on the northern part of the Pilis Mts were reported by FEICHTINGER (1864, 1899). Contrary to his other floristical studies he enumerated the .occurring species by their localities. Numerous authors published floristical data on the Pilis Mts (BOROS 1917, 1919, 1923, 1938, 1970, CSAPODY 1935, 1939, DOMOKOS 1939, GRÜNDL 1863, FEKETE and JAKUCS 1957, HORÁNSZKY 1957, JÁVORKA 1904, 1915,1940, LENGYEL 1906, 1909). However, few studies contain data on Kesztölc and its close surroundings. Floristical data on the marshlands in the vicinity of Kesztölc and on the meadow Hosszú-rét between Piliscsaba and Piliscsaba-Jászfalu were published by PENKSZA (1991). The most important floristical data on the cliff Fehérszirt (PENKSZA 1992a) and the coenological characterization of the marshlands found here were provided by PENKSZA (1992b). The phytogeographical features of the Pilis Mts and its surroundings were described by BOROS (1953) and FEKETE (1988). BORHIDI (1956) studied the sandy vegetation of the Kisalföld. The "embayment" south of Esztergom was given the name "the vicinity of Esztergom" by ZÓLYOMI (1958). SIMON (1962) provided an overview on the natural vegetation of the Kisalföld. The monograph of the marshlands by KOVÁCS (1962) contains information on the region, too. The detailed potential vegetation map by SIMON et al. (1980) refers the area, as well as JAKUCS and FEKETE (1987) in the serial "The landscape geography of Hungary". The vegetation of the hills Kétágú-hegy and Csévi-szirtek were compared by SZERDAHELYI (1988, 1989). The vegetation map of Kétágú-hegy and its surroundigs was described by PENKSZA et al. (1997). Our vegetation mapping studies started in 1982 at some regions of the Landscape Protection Area of the Pilis Mts, Hungary, with the aims of searching and point-mapping of rare, protected species in the strictly protected areas. The data were re-examined by fieldwork in 1996. Therefore the changes of habitats since 1982 are appeared in the results presented below.
