Belgian authorities have determined that additional cleanup work is required at the Galgenschoor nature reserve along the River Schelde, more than two months after an oil leak at the Deurganckdok (a major shipping dock within the Waaslandhaven port complex near Antwerp). The Institute for Nature and Forest Research (INBO) warned that remaining oil patches on riverside stonework could become sticky again in warm weather, risking renewed contamination of birds and damage to aquatic life. Port of Antwerp-Bruges, along with Flemish waterway and nature agencies, has been tasked with carrying out the works as soon as possible, with INBO advising that cleanup be carefully coordinated to avoid disturbing nesting birds — including the marsh harrier, which breeds in the area — during the ongoing breeding season.
