Anti-fracking campaigners in the UK are enjoying at least a temporary victory on Friday following news that energy company Cuadrilla was pulling out of a shale gas site in Lancashire.

Cuadrilla, which the Guardian notes is “the UK’s only company engaged in fracking,” cited “technical constraints related to wintering birds” as the reason behind its leaving the fracking site.

Cuadrilla has been the target of sustained protests, with thousands of anti-fracking campaigners shutting down the company’s headquarters, their PR company and their drill site in Balcombe in August.

Environmental groups gave a cautious welcome to the news, warning that the mission to stop fracking was far from over.

“We’re pleased they’ve pulled out but we want them to pull out of all of Lancashire because of the huge threat to the environment,” stated Helen Rimmer, Friends of the Earth’s North West campaigner. “They’ve obviously felt the pressure of the local opposition and know they’re not welcome.”

Harry Huyton from the Royal Society for the Protection of Birds said that “It is promising news that Cuadrilla has taken wildlife into account in this case, but in the long term there must be a statutory obligation of drilling firms to assess the impact any proposal will have on birds and other species.”
