Other Site Characteristics

Este LIC se ciñe al tamo alto del río Onsella, entre Longás y Navardún. Discurre en dirección E-W en el núcleo del Prepirineo Zaragozano, entre la sierra de Santo Domingo al Sur y la sierra Puig D´Arás al norte, siendo tributario por la margen izquierda del río Aragón. El régimen hidrológico es de tipo pluvial presentando máximos caudales primaverales y mínimos estivales. Destaca la buena conservación de sus márgenes con formaciones de ribera dominadas por Populus nigra y alba, Salix alba y dominando las formaciones arbustivas del género Salix principalmente Salix eleagnos. El río presenta un estado de conservación bueno, con algunos cultivos en zonas próximas al cauce.

4.2 Quality and importance

Destacan las formaciones de ribera maduras en algunos sectores con una gran diversidad especifica y que actúan como refugio de la flora y fauna.
