During the LIFE-CWR project "Ecological Restoration and Conservation of Praia da Vitória Coastal Wet Green Infrastructures", there was the opportunity to undertake a systematic record of bryophytes at Paul da Praia da Vitória (PPV), Paul do Belo Jardim (PBJ) and Paul da Pedreira do Cabo da Praia (PPCP), three coastal wetland areas of Praia da Vitória (Terceira, Azores, Portugal). The objective of the study was to perform a biodiversity assessment, comparing the three sites at two different moments, before and after the implementation of several conservation measures. This project also contributed to improve the knowledge of Azorean bryophyte diversity at both local and regional scales, including the recording of two new taxa for the Azores and three new taxa for Terceira Island. This paper reports the results of the first extensive survey of bryophyes of the three coastal wetland areas of Praia da Vitória (Terceira Island, Azores, Portugal). The identification of a total of 504 samples, 240 collected in 2013 and 2016 (before the LIFE-CWR intervention) and 265 in 2017 and 2018 (after the intervention), resulted in a list of 58 species of bryophytes (one hornwort, eight liverworts and 48 mosses). These include two new records for the Azores (Bryumklinggraeffii, Ptychostomumbornholmense), three new records for Terceira Island (Bryumtenuisetum, Dicranellahowei, Trichostomumcrispulum) and at least 15 new records for the municipality of Praia da Vitória (e.g., Cephaloziellahampeana). Some species that had not been recorded on the island since 1937 (e.g., Fissidenscrispus) were collected during this study, as well as a Macaronesian endemic liverwort (Radulawichurae), an Iberian-Macaronesian liverwort (Frullaniaazorica) and a moss species with European distribution (Ptychomitriumnigrescens). From the recorded species, only one moss (Leptophascumleptophyllum), of subtropical origin, is considered invasive in Europe.
