Abstract
Berlengas archipelago is a UNESCO world heritage site and the only location where Armeria berlengensis is found. This species faces various threats, namely, human disturbance, the presence of Carpobrotus edulis, yellow-legged gull, common-rabbit, and black-rat populations. Thus, exclusion areas were installed, which blocked the access of most Gulls, aiming to promote the recovery of A. berlengensis. Additionally, rabbits and rats were removed from the island. After six years of surveys, there has been an increase in the number of individuals of A. berlengensis in the exclusion areas, and a clear shift in the size structure of the A. berlengensis population. Significant changes in the height and diameter of the individuals were also noted. These findings indicate that the population of A. berlengensis is changing and becoming a healthier population. Principal component analysis results show a straightforward dissimilarity between the areas with A. berlengensis and those without the species and allowed the clustering of two groups: the rupicolous species and the nitrophilous species. A. berlengensis produces few seeds (seed set 3.4%), which raises concern regarding the long-term survival of the species. Thus, further conservation efforts must be implemented, such as the control of invasive species, gulls, and ruderals, to allow for the recovery of A. berlengensis.Keywords
