Cambridge university have apologised for using controversial nets on trees at its West Cambridge site.
The nets, which were put over the trees to discourage nesting birds, were widely criticised by environmentalists, including Chris Packham.
He called the nets 'absolutely outrageous' and said they made him 'feel sick'.
Last year he had been a vocal critic after nets were used in Bacton.
The netting was put on more than twenty trees at the Whittle Laboratory while building work is carried out.
After pressure from climate change campaigners and environmentalists, they've not apologised "unreservedly" saying the decision to put the nets up was "wrong".
On Thursday night climate activists from Extinction Rebellion cut down and removed a number of the nets.
Cambridge university say they'll take advice from experts before taking any further action.
