Ed Sheeran's European promoters have been forced to move an open-air show as 104 trees were at risk.
The concert was to take place in a large car park in Dusseldorf in July, but local conservationists stopped a licence being granted.
FKP Scorpio released a statement saying the shows would be moved to an arena in a nearby city.
An extra date will also have to be added to the tour to accommodate the smaller size of the venue.
The shows, due to accommodate 80,000 fans a night, were going to take place in the car park of a new exhibition centre. They were moved as the gigs would have led to trees being cut down, despite promises from the council to plant more.
"The artist and organisers want to give fans clarity as quickly as possible," the statement reads.
