A chemicals firm is to carry out surveys in Sherwood Forest in Nottinghamshire - which green campaigners fear could lead to fracking.
It's potentially a first step towards searching for shale gas beneath the legendary home of Robin Hood.
The company says Friends of the Earth, who've revealed the plans, are just scaremongering. Watch the full report from our correspondent Peter Bearne.
A spokesperson for The Forestry Commission, the department responsible for all of the country's forests said:
"The UK will use oil and gas for many decades and using the resources we have in the UK would give us better security over our energy supplies and make us less reliant on imports. INEOS has a licence from the Oil and gas Authority (OGA) for ‘onshore hydrocarbon exploration, appraisal and extraction’. Forestry Commission England will consider any applications from licenced operators to investigate, explore or extract on land we manage."
Commenting specifically on the matter in relation to Nottingham the commission said:
"We have been contacted by INEOS regarding access to the Public Forest Estate in north Nottinghamshire and will carefully consider the potential impacts and their effects. We have not agreed a licence or access to land we manage for INEOS to begin seismic surveys or any other work."
