Abstract
Neste traballo avalíase a importancia botánica para a conservación da contorna da Fraga de Sto. Estevo do Ermo, situada no concello de Barreiros (Lugo, NW España). Dentro das 331 ha que comprende este espazo, identificáronse un total de total de 219 taxons de plantas vasculares, das que 19 (8,6% do total) son Pteridófitas. Seis taxóns, entre eles os fentos Dryopteris aemula, Vandenboschia speciosa e Woodwardia radicans, son especies protexidas cuxas poboacións locais están asociadas ás 15,2 ha que ocupan os 6 tipos de hábitat do Anexo I da DC 92/43/CEE (dous deles de carácter prioritario) recoñecidos na área de estudo. A pesar da reducida superficie que ocupan estes ambientes ecolóxicos, este enclave pode cualificarse como un lugar de gran relevancia para a conservación das pteridófitas a nivel rexional
This study assesses the importance of the Fraga de Sto Estevo do Hermo and its surroundings (Barreiros council, Lugo, NW Spain) as a botanical conservation site. A total of 219 taxa of vascular plants were identified, 19 of them (8,6%) being Pteridophytes. Six species (Ilex aquifolium, Ruscus aculeatus, Narcissus triandrus, and the ferns Dryopteris aemula, Vandenboschia speciosa and Woodwardia radicans) are protected species. They were associated to the 6 habitat types of the Annex I of the CD 92/43EEC that exist in the area, which occupy only 15,2 out of the 331 ha of the whole study area. Despite the small area covered by these habitats, this site can be qualified as very important for pteridophyte conservation at the regional level
