Oro-Pannonic steppe ash-lime woods

Loosely closed forests mainly of [Tilia platyphyllos] and [Fraxinus excelsior] developed on shallow soils of exposed crests of limestone mountains (more rarely on andesite rocks) of the Northern Hungarian Range, with an herb layer of [Brachypodium pinnatum], [Galium erectum], [Cruciata glabra], [Digitalis grandiflora], [Erysimum odoratum], [Sisymbrium strictissimum], [Aconitum anthora], accompanied by endemics among which [Hesperis vrabelyiana], [Carduus collinus] and by other regionally rare species with disjunct distribution, such as [Waldsteinia geoides], [Melica altissima], [Carex brevicollis]. They constitute relict forests, most probably of the Boreal era, and are of great biological value.
