The bryophyte flora of Castel Volturno Nature Reserve (Southern Italy) was investigated, and a list of 42 collected species (37 mosses and 5 liverworts) was compiled. Sematophyllum substrumulosum (Hampe) Britton is new to the Campania bryoflora. Within the study area, two sectors characterized by different disturbance history and environmental conditions could be clearly recognized on the basis of floristical, chorological and ecological considerations. The sector located in the southern part of the Reserve and characterized by a more heterogeneous and frequently burned vegetation showed the richest bryoflora, with a dominance of the submediterranean element. Water and substrate affinity afford a richer heterogeneity of habitats in this sector, while light seems not to be a limiting factor.
