Alterations and changes that affect the conservation of the biodiversity of Estanho de Vilac (Aran Valley) (original) (raw)

Estanho de Vilac, situated in the Aran Valley of Catalonia, has undergone significant ecological changes due to external water supply for livestock and trout fishing, impacting its biodiversity. This study investigates the water cycle, nutrient dynamics, and aquatic biodiversity to advocate for the conservation of critical species, such as Alytes obstetricans, Rana temporaria, and Luronium natans, all protected under European law. The findings indicate a temporary pond ecosystem, where external interventions have led to biodiversity decline, prompting several restoration actions including trout removal and regulated water inlet adjustments to recover natural ecological balance.
