The results of a study on the bryofloras of three historical gardens (Villa Giulia, Parco d'Orléans and Giardino
Garibaldi) and other four smaller green areas (at Niscemi, Stazione Lolli, Castelnuovo e Kalsa squares) of Palermo are provided.
These bryofloras (including 65 taxa) are analyzed from the taxonomic, ecological and chorological point of view and
compared with Botanical Garden one. Bryofloristic indices, used as instrument of environmental evaluation, show that
bryophyte flora of smaller green areas is more affected by building and traffic density of surrounding zon
