Abstract
The Peneda-Gerês National Park (PNPG) in North-western Portugal has been the subject of many bryological studies although there remain unstudied areas. We here present a summary of current knowledge using data from recent fieldwork and past data which comprises ca. 11000 records. Using this data twelve Important Plant Areas (IPAs) were selected. The PNPG is an area exceptionally rich in bryophytes as shown from current species richness distribution maps. There has been a significant increase in the level of bryophyte of the PNPG since 1980. From recent fieldwork, two new species to Portugal were found and fourteen species are reported as new to this National Park. Future studies in relatively unknown areas will most likely lead to the discovery of further bryophytes of conservation importance. The IPAs mapped can be useful in guiding conservation planning.
Highlights
The Peneda-Gerês National Park (PNPG) is one of the best studied areas in Portugal for bryophytes and one of the first areas in the country with bryophyte collections, for example, Mnium fontanum L. collected by Brotero (1804), “Ad fontes et in udis subalpinis Gerez, et alibi”
Data collected in the June 2010 survey are presented in Table 2; new taxa to Parque Nacional Peneda-Gerês (PNPG) are indicated with an asterisk (*) and species which are new to Portugal are indicated with two asterisks (**)
16 taxa were recorded for the first time in PNPG including two Habitat Directive species and two new species to Portugal
Summary
The Peneda-Gerês National Park (PNPG) is one of the best studied areas in Portugal for bryophytes and one of the first areas in the country with bryophyte collections, for example, Mnium fontanum L. collected by Brotero (1804), “Ad fontes et in udis subalpinis Gerez, et alibi”. Hespanhol et al (2005) provided an updated distribution of bryophytes to this area, including potential areas of occurrence for some threatened/rare bryophyte species. Despite these studies, the knowledge of bryophyte distribution in this National Park varies considerably between areas. For some there are recently published distribution maps and detailed species lists including conservation status, habitat quality and new species (Hespanhol et al.
