Calls have been made for a third national park to be established in Scotland.
All four opposition parties in Holyrood made manifesto commitments to create more parks.
Currently there are two, the Cairngorms and Loch Lomond, but campaigners have been urging the Scottish Government to establish more to preserve the country’s natural heritage.
The campaign was launched in 2013 by the Association for the Protection of Rural Scotland (APRS) and the Scottish Campaign for National Parks.
John Mayhew, APRS director, said: “There is now a majority of MSPs in favour of more national parks. We are plugging away at national level and encouraging local groups to support the idea, with campaigns up and running in the Borders, Galloway, Mull and Harris.”
Campaigners have outlined seven potential sites including Glen Coe and the Black Mount, Glen Affric, Wester Ross, and Harris.
Last week a group pushing for a Borders national park were given Big Lottery funding to carry out a feasibility study.
While opposition parties are in favour of new parks, the Scottish Government has said there are no proposals currently being considered.
A government spokeswoman said: “There are no current plans to designate new national parks in Scotland. The creation of new national parks requires considerable planning and it carries cost implications.
“We believe that it is essential to focus support on our two existing national parks to ensure that they continue their valuable contribution to tourism and sustainable rural economic development.”
