Resumen

En el presente trabajo se describe y analiza la repelencia al agua detectada en una pequeña cuenca hidrográfica afectada por fuego controlado en el área montañosa central de Portugal. También se establece una discusión acerca de los métodos utilizados para medir la hidrofobia y el grado de correspondencia entre los resultados obtenidos en el campo y en el laboratorio. Los resultados muestran la escasa influencia del fuego controlado sobre los parámetros físicos y contenido de materia orgánica del suelo, indicando, sin embargo, una estrecha relación entre la distribución espacial de Erica sp. y suelos más hidrófobos. El grado de replicación entre la hidrofobia medida en el campo y en el laboratorio es discreto; no obstante, en el laboratorio sí se ha encontrado un buen nivel de correspondencia entre las dos técnicas utilizadas (Molarity of an Ethanol Droplet y Water Drop Penetration Time).
