Bulgaria and Romania on Tuesday signed a deal to set up three wetland areas along their joint 470-kilometre (290-mile) Danube border, protecting pelicans, herons, pygmy cormorants and other birds, the environment ministry here said. The agreement will establish a zone in the east around Bulgaria's Lake Srebarna and Romania's Lake Calarasi; a second in the centre, around Belene island and Lake Suhaia; and a third in the west, around Ibisha island and Lake Bistret. It was signed by environment ministers Ulian Popov of Bulgaria and Rovana Plumb of Romani.
