Sussex Police have begun to reduce their presence at the protests in Balcombe after four months of demonstrations.
Hundreds of activists protested in Balcombe against the drilling site opened by energy company Cuadrilla, who have now left the area.
No Dash for Gas, who organised the camp protests, said they would continue to support the people of Balcombe and return in the future.
Protesters believe the drilling could lead to fracking, which they claim imposes risks to the environment such as earthquakes.
Many officers and staff had worked longer shifts or cancelled days off and the force had called on mutual aid from the rest of the UK.
We have known this would be a long-running policing operation and, while we are scaling down, we still expect to need a presence at the site for a number of weeks."
