Las observaciones sobre el cambio medioambiental realizadas por usuarios locales pueden ser una importante fuente de información sobre las características medioambientales del pasado y del presente para complementar los estudios científicos y el monitoreo. En este estudio cualitativo documentamos observaciones sobre el cambio medioambiental realizadas por 27 ganaderos en los dos valles más occidentales de los Pirineos centro occidentales españoles. Resumen cambios climáticos relativos a la disminución del caudal de las fuentes de montaña y al aumento de la cubierta vegetal de matorrales y arbolado en las montañas. Las explicaciones sobre el aumento de arbolado difieren en los dos valles; sin embargo la mayoría de los ganaderos de ambos pueblos pensaban que la falta de presencia humana en las montañas contribuye a la invasión del matorral. Las observaciones de los ganaderos sobre los cambios medioambientales sugieren la necesidad de investigaciones adicionales sobre los cambios climáticos y de vegetación en los Pirineos y evidencian las potenciales contribuciones del conocimiento local de los ganaderos para el monitoreo medioambiental, la investigación y la gestión.
