  • On the basis of the information collected from some Herbaria (MCA, ARAN. IT and data banks, we have established a critical list of the 316 endemic plants (iberian and pyrenean) to be found on the western half of the Pyrenees (Aragon and Navarre). Their altitudinal range and ecology have also been studied. Among 2554 species and subspecies living in the area, we have distinguished several types of rarity and threat arriving to a list of 81 taxa. Many of these rants (endemic or not) are affected by the public works such as new ways and by the degradation of wet areas as well. Nevertheless, few taxa are critically threatened.
