[EN] Trampling is one of the most visible forms of disturbance to vegetation as a result of recreational use resulting in loss of vegetation height and cover and changes in plant community composition. In order to identify and quantify such impacts, a study on Capo Sant Elia, a calcareous promontory located within the municipality of Cagliari (southern Sardinia) is carried out. This area is characterised by a great naturality and floristic diversity, with a high number of plant species very interesting from biogeographic point of view, as well as a recreational area much frequented by hikers and mountain bikers. Among these species, Globularia alypum L, represents a particular interest because its population in Sardinia is the westernmost station of the species in Italy. Effects of trampling on Mediterranean shrub G. alypum was evaluated realizing transects located a different distance to the paths. Moreover, the population size of G. alypum in Capo Sant Elia was quantified by a census and the estimation of visitors number (both cycling and walking) that frequented this area. The results of the present study allow to know the effects of trampling on G. alypum, the disturbances and threats factors for this species in the study area and the size of the Sardinian population. The results achieved will be useful to propose management actions for guaranteeing the conservation of the taxon. Rodríguez Martínez, P. (2016).
