摘要：In the Vals an Valley there are two categories of regions that have been declared protected areas: The Natural Reserve Valsan Valley, code 2125 and The protected natural area of community interest Valsan Valley, code ROSCI0268. The aim of the research was to identify the species of pteridophytes in the protected area s , a necessary step for the conservation of their diversity. Within the area researched 26 species of pteridophytes were determined. Specific diversity across the genera identified ranges from 5 to 1, thus: Equisetum (5), Asplenium (4), Dryopteris (4), Polystichum (3) and Huperzia, Lycopodium, Selaginella, Botrychium , Polypodium, Phegopteris, Athyrium, Cystopteris, Gymnocarpium, Matteuccia with only one species. Concerning the abundance of the species identi fied, the pteridoflora in the area res earched is made up of frequent (73%) and sporadic species (27%), such as Huperzia selago , Lycopodium annotinum , Botrychium multifidum , Asplenium scolopendrium , Matteuccia struthiopteris , Dryopteris expansa , Polystichu m braunii
