Other Site Characteristics

Riva settentrionale del Lago d'Idro (Valle del Sarca) con vasti canneti e soprattutto magnocariceti; di particolare interesse una valle percorsa da un immissario del lago e completamente invasa da magnocariceti. Sono presenti habitat di particolare interesse non compresi nell'all.I della direttiva 92/43/CEE: Caricetum elatae e Caricetum gracilis (40%), Phragmition (30%).

4.2 Quality and importance

Sito di eccezionale importanza a causa della vegetazione lacustre sulle rive del lago e delle vaste paludi sviluppate sul fondo di una vallecola che si immette nel lago stesso; ambiente unico nel suo genere, con associazioni vegetali sempre più rare a causa delle bonifiche nelle zone alluvionali di fondovalle. Il sito è inoltre di rilevante importanza per la nidificazione, la sosta e/o lo svernamento di specie di uccelli protette o in forte regresso, e/o a distribuzione localizzata sulle Alpi.
