In this study, the fern flora of Akçaabat in Sera Lake Nature Park, which is important in terms of socio-economic contributions to Trabzon province, was evaluated. The ferns from the nature park in 2024 were collected and their various morphological features including leaves and stems were studied in the laboratory. The identification was done using the determinants, keys on the floras. Specimens were identified as seven species. These species belong to the families Aspleniaceae (Asplenium scolopendrium L., A. trichomanes L., A. adiantum-nigrum L.), Polypodiaceae (Polypodium vulgare L.), Equisetaceae (Equisetum arvense L.), Pteridaceae (Pteridium aquilinum (L.) Kuh), Dennstaedtiaceae (Adiantum capillus-veneri L.). Sporangium and spore structures of ferns were studied in detail for the first time in the country.
