Part of an ancient Caledonian forest in Perthshire, Scotland, could be destroyed if plans for a £1.3bn resort development are given the green light, according to the Woodland Trust Scotland (WTS).

The BBC reported that Dall Estate and M James Developments have submitted plans to Perth and Kinross Council to build a private members club next to Loch Rannoch, including a 104-suite hotel, two golf courses, a health spa and a residential scheme. A lochside restaurant, concert hall and a retail arcade have also been proposed. However, WTS said that the plans - if approved - would result in the loss of 160 hectares (395.4 acres) of historic forest, while an additional 240 hectares (593.1 acres) of associated woodland would also be at risk from the development.

The South Rannoch woodland was formed at the end of the last Ice Age and is considered to be one of the last remaining wildernesses across the British Isles, boasting rare eco-systems and wildlife habitats. According to WTS, the potential loss of woodland would cover an area the same size as London's Regent's Park and would threaten wildlife species such as the capercaillie, which is 'red-listed' and considered to be at risk from extinction.

Andrew Fairbairn, WTS policy and communications manager, said: "The proposals will effectively pour concrete over this habitat, destroying the valuable wildlife within and isolating the Black Wood of Rannoch even further. "Ancient Woodland is an irreplaceable habitat and there has been no attempt to minimise the damage to it, it will just be razed to the ground if this goes ahead."

Scottish Natural Heritage (SNH) has also voiced its opposition to the proposals, which the organisation said would have a major effect on the landscape of Loch Rannoch. SNH area manager Denise Reed said: "The design and scale of this development would be out of place in its surroundings and could have far-reaching and harmful impacts on a part of Scotland renowned for its iconic and dramatic scenery.

"Ancient Caledonian pine woods are only present in Scotland, and it is crucial for SNH and others to ensure their long-term future. We are very concerned that this proposal could compromise this protected and unique area."
