Northern Powergrid are hoping to remove two diggers, trapped in a rare bog in Cumbria, within a few days.
Two machines became trapped in the area of scientific interest last week. Environmentalists are worried this will cause damage to the area, Butterburn Flow, which is considered to be the most important site of its kind in England.
"Our contractors were completing a project to replace wooden electricity poles in the area, when their vehicles got into difficulty.
Close consultation is taking place with Natural England to ensure they are retrieved from the site in a controlled and careful manner with no lasting impact on the local environment.
This work has started and we hope to have the vehicles removed in the next few days."
