The firm has promised to consult before taking any plans forward
A bid by an energy company to explore the potential development of a new wind farm in Dumfriesshire has been approved by the Scottish Government.
It has overturned the local council's decision to block the construction of a wind speed mast in Auchencairn Forest.
Protestors fear the project could lead to more turbines.
A spokesman for the company behind the plans, Acciona, said it would consult with the public before any such plans were put forward.
The wind mast equipment will be used to monitor wind speed and assess the area's suitability for development.
The site being studied is close to another 15-turbine wind farm, which was officially opened last month.
