Németh, Csaba: Data on the distribution of some rare alpine-boreal bryophytes in the Vértes Mts (Hungary)

New records of occurrence: Csákberény: Cseresnyés-völgy (14.10.2006,47° 22'56.9" N, 18° 19'31.3" E, alt. ca408 m); Csonka-bükk (21.10.2006, 47° 23' 10.4" N, 18° 19' 17.9" E, ait. ca 384 m); Ugró-völgy (10.09.2005,47° 22' 13.3" N, 18° 18' 53.5" E, ait. ca 392 m); Ugróvölgy (Szentegyházi-hegy) (16.05.2005,09.09.2006,47° 22'05.0" N, 18° 19' 12.9" E, ait. ca 365 m); Gánt (Kápolnapuszta): Antal-árok (23.10.2006,47° 23' 58.5" N, 18° 20' 08.4" E, alt. ca 379 m); Gánt (Vérteskozma): Tábor-hegy (29.09.2006, 47° 26' 55.8" N, 18° 26' 33.3" E, alt. ca357 m); Szár: Holdvilág-árok (30.04.2005,47° 28'

20.2"N, 18°27'42.6"

E, ait. ca308m); Vértesboglár: Macska-gödör (29.10.2005,47° 27' 30.5" N, 18° 27' 19.9" E, ait. ca 308 m). CONCLUSION Based on our results it is proved that investigating the special habitats of a small region several new data on rarities can be obtained. Data on the recent distribution of rare bryophytes are important nowadays when the preparation of a new red list of bryophytes of Hungary are in progress, and several national and international efforts draw attention to the bryophyte conservation. With the help of the distribution maps of the species the hot spots of rare bryophytes living on shaded, humid limestone rocks can be outlined in the Vértes Mts.
