Bryophytes from exposed rock outcrops in the North and Centre of Portugal: distribution and conservation

Abstract

We update the catalogue of Portuguese bryophytes from exposed rock outcrops, based on recent fieldwork. 128 taxa were found in the North and Centre of Portugal, on rock surfaces, fissures, cavities and rock pools. The most frequent taxa belong to Grimmia, Andreaea, Racomitrium, Hedwigia, Cynodontium, Hypnum and Polytrichum genera. 29 bryophytes are new to different Portugal Provinces. Current threat status of bryophytes from rock outcrops in Portugal was evaluated according to IUCN criteria, and 19 bryophyte taxa were considered as “Threatened” (CR, EN and VU categories) at the national level.
