Riparian habitats of the Adda river, a tributary of the River Po. Habitats are dominated by shallow standing water, aquatic vegetation and wet woodlands, and the site is surrounded by cultivated land and poplar Populus plantations. The main land-uses are nature conservation and agriculture.
There are two large mixed heronries, called Garzaia di Cascina Pioppo and Garzaia di Zerbaglia. The latter was listed in the previous pan-European IBA inventory (Grimmett and Jones 1989) as `La Zerbaglia' (former site IT022).
