Description
West of the Timavo springs, there is an area that used to be sea but is now surrounded by a stony bank circumscribing a back-filled polder created to receive the materials deriving from the excavation of the channel leading to the port of Monfalcone. The eastern side has been declared a Site of Community Importance (SCI) for its wealth of birdlife. Within the area, a part is occupied by a mudflat with an abundant presence of sea purslane (Atriplex portulacoides), while towards the outer bank there is a stretch of shallow water linked to the sea via a gap in the wall. Despite having been considerably disturbed, the area is rich in birdlife. North and west of the back-filled polder, there are large reed beds, stretches of fresh water and riparian woods of willow and poplar growing on old polders.
