%X Wild boar rooting is nowadays one of the main disturbances in Pyrenean alpine grasslands. Its consequences for the ecosystem are not perfectly understood yet despite alpine grasslands in the Pyrenees have an important economic role and a priority conservation interest. The ecosystem services of this habitat lay mainly on pastoral and ecological values that wild boar rooting seems to affect. In this study, we measured those ecological and pastoral values at different scales to improve our understanding of the reach of these disturbances in this sensitive ecosystem. At landscape and community scales we compare disturbed and undisturbed areas in pastoral, ecological and community maps of the study area by means of a geographic information system. At a local scale we compare ecological and pastoral values of different plant groups (based on species abundance), within and outside wild boar rootings. A preference for areas of high pastoral and intermediate ecological values was found for wild boar rooting at the landscape level. However at the community level, disturbances notably reduced pastoral and ecological values in all communities. At the local level, the ecological value of bulbs and the pastoral value of annual dicots increased within disturbances, suggesting that disturbances may favour functional group diversity. In sum, wild boar rooting affects Pyrenean alpine grasslands moderately, with higher affection to pastoral than ecological values at all levels, what should be considered for the management and preservation of these habitats since these disturbances are likely to increase. Las hozaduras de jabal¨ª son una de las mayores perturbaciones actuales de los pastos supraforestales pirenaicos. Sus consecuencias para el ecosistema no est¨¢n todav¨ªa perfectamente descritas, a pesar de ser uno de los h¨¢bitats de mayor inter¨¦s de conservaci¨®n y que juegan un importante papel en las econom¨ªas locales. Los bienes y servicios que provee dicho h¨¢bitat est¨¢n claramente relacionados tanto con su valor ecol¨®gico como pastoral, los cuales parecen estar afectados por las citadas perturbaciones. En este trabajo se midieron dichos valores dentro y fuera de perturbaciones a diferentes escalas espaciales para incrementar el conocimiento de la repercusi¨®n de las hozaduras de jabal¨ª en el ecosistema de los pastos alpinos, particularmente sensibles a la remoci¨®n del suelo. A escala de paisaje y de comunidad, comparamos las ¨¢reas perturbadas y no perturbadas por el jabal¨ª, en mapas del valor pastoral, valor ecol¨®gico y de comunidades pasc¨ªcolas de la zona de estudio, por
