The estuary of the torrent Voutsides is located about 1.4 km west of Evdilos in the village Kampos. It is a natural coastal wetland area of 34.4 acres.
The torrent is with a relatively permanent flow throughout the year and brackish water and feeds mainly on small farmers scattered along the riverbed.
The wetland is located within an area declared as archaeological area of Kampos and as Wetland Plain (estuary Voutsides).The wetland has a rich biodiversity of flora and fauna, as well as populations of many protected and endemic species. It presents an ultra-water vegetation of reeds and rushes, which dominate the entire area and oleanders, osier, alders, trees and lentisk.
It also hosts a wide variety of birds, reptiles and amphibians.
The activities in the watershed are relatively mild, mainly grazing and cultivation. The major threats to the wetland resulting mainly from these two activities, are overgrazing and the intense irrigation of crops, that takes place uncontrollably by tires from the riverbed, thereby reducing the water level.
Lately, another intense threat to the habitat is the increased tourism during the summer months, since at the end of the estuary, there is a sandy overcrowded beach in Kambos.
