The possible extension of the Clwydian Range Area of Outstanding Natural Beauty (AONB) will be decided on by Welsh assembly government environment minister Jane Davidson after plans were recommended by the Countryside Council for Wales (CCW).
Such a move could boost those who go walking
in these areas as they may continue enjoying an unspoiled environment due to the extra protection to status will afford them.
Despite opposition from the National Farmers' Union (NFU), the CCW has backed the plan to add the Dee Valley and Llangollen to the AONB, noting it has carried out a wide-ranging public consultation.
And the scheme has also gained the support of Denbighshire and Wrexham County Borough councils.
Commenting on concerns expressed by the NFU, Chairman of the CCW Morgan Parry said giving the new areas protected status "would not bring new restrictions on agricultural activities".
The Clwydian Range is 35 km in length and its highest point is Moel Famau, 554 m (1,817 ft) above sea level.
