Supermarket chain Tesco has won a High Court order to remove a tree protester who wants to prevent a new development.
Up to 30 campaigners have joined the protest
Oliver Carter has remained in a giant Scots pine, due to be felled with 200 other trees to make way for a store and homes, since 16 February.
On Wednesday, Mr Carter, 24, came down from the tree in Shepton Mallet, Somerset, in a bid to obtain an adjournment of the case in London.
But Mr Justice Park granted Tesco an order for possession.
While Mr Carter was away, 15 campaigners camped out in shifts in his home 40ft up the tree, which is reached by walkways.
Tesco has said it will replant more trees than are removed from the site.
After the hearing, Mr Carter said: "I'm disappointed, very disappointed with the legal system and we are now planning to launch an appeal."
