Dog walkers in Dublin will have to exercise more restraint to preserve ground-nesting birds on North Bull Island. The Dublin City Council’s new access management plan demands dogs kept on leads in most areas, with a dedicated off-leash spot kept away from bathing and bird-nesting areas. Those who infringe could face a fine of €150 ($177). The plan also prohibits access to the island’s salt marsh and the northern tip, which is a significant pupping and haul-out area for seals. The council aims to keep the area ‘special’ by promoting responsible behaviour among some 2 million visitors each year.
