Chairman James Fraser told BBC Scotland that in villages near Stirling, Glasgow and Edinburgh, the new homes would be bought up by commuters."It is very disappointing to see the scale of loss of family run hotels in the national park in recent times, but this is inevitable given the major challenges and pressures faced by owners in such a difficult trading environment," he said.
He said he expected the national park's new five year plan would major on climate and nature emergencies, but he added: "It is also vitally important that they also try and tackle the people dimension to reverse the drift towards creating more dormitory towns and villages. "We continue to receive regular applications for new accommodation. Overall, the decrease in some types of accommodation needs to be viewed with a broader view that includes new accommodation, particularly non-serviced accommodation, which is in growing demand."
