Résumé :	In this essay the changes of the vegetation cover from Les Llaunes reserve (NE Iberian Peninsula) are assessed throughout seventeen years of protection. We propose a methodology to evaluate the effects of several management activities on the vegetation in the small protected natural areas, based on the analysis and comparison of vegetation maps of the area made at different times by means of geographic information systems. The variations of the vegetation cover allows to detect, in a simple way, considerable changes in the system. The areas where the vegetation has undergone the most considerable variations coincide with those where management activities (flooding, grazing, change in the soil uses, etc.) have been implemented. The study shows how one same management action may derive into completely different results (positive or negative) according to the initial plant community.
