Plans for a controversial new golf course on protected Highland coastline have been rejected by Scottish ministers after a planning battle stretching back more than a decade.

The proposed 18-hole Coul Links course near Embo in East Sutherland had been backed by Highland councillors but faced sustained opposition from conservation groups over its potential impact on internationally important dunes, wetlands and wildlife.

Scottish ministers have now refused planning permission, concluding the development would cause significant harm to nationally and internationally important habitats and species.

The decision brings the latest three-year planning process to an end and represents the second time ministers have rejected proposals for a golf course at Coul Links.

Plans for a “world-class” course at the site, less than five miles from Royal Dornoch Golf Club, were first revealed in 2015.

An initial application was eventually rejected by Scottish ministers in 2020 following a public inquiry and a high-profile campaign by environmental groups.

A revised proposal was submitted by Communities for Coul in February 2023.

It included an 18-hole golf course, practice area, parking, access, clubhouse, pro shop and maintenance facilities.

Highland Council’s north planning applications committee voted eight to six in favour of the plans in December 2023, despite planning officials recommending refusal.

NatureScot maintained an objection to the development, meaning the application had to be referred to Scottish ministers. Ministers called it in for their own determination in February 2024.

A public inquiry was held in Embo in November 2024 before government reporters David Buylla and Stuart West examined the proposal.

Their report concluded the development was contrary to the development plan, with particular concerns over building a substantial development on undeveloped coastline and the potential damage to environmental assets.

Ministers have now agreed with that conclusion.

The decision found the proposal would result in “significant adverse effects on nationally and internationally important habitats and species”.

Coul Links forms part of a Site of Special Scientific Interest and is also covered by internationally important Special Protection Area and Ramsar wetland designations.

The coastal dunes contain a mixture of wetlands and other habitats supporting rare species including Small Blue and Northern Brown Argus butterflies and Fonseca’s Seed Fly, an endangered insect found only along a small section of the Sutherland coast.

Supporters argued the golf course could provide a substantial economic boost for East Sutherland, bringing visitors, jobs and investment to the area.

Communities for Coul had also argued that income generated by the development could help fund the long-term restoration and management of habitats at the site.

The group reacted angrily to the refusal.

Director Gordon Sutherland described the decision as “a real blow for our area’s economy and its unique environment” and a “slap in the face for local democracy”.

Supporters had claimed the wider project had the potential to support around 400 jobs and help tackle the loss of working-age people from the area.

Landowner Edward Abel Smith said he was “absolutely gutted” by the decision after more than a decade spent trying to bring a course to Coul Links.

Environmental groups welcomed the outcome.

RSPB Scotland said Coul Links was one of Scotland’s last undeveloped sand dune habitats and argued that construction of the course would have caused irreversible damage to protected areas.

The charity said tens of thousands of people had taken part in campaigns against development at the site, while hundreds of objections were made during the latest planning process.

The Not Coul community group and organisations including Buglife, Butterfly Conservation Scotland, the Marine Conservation Society, National Trust for Scotland, Plantlife Scotland and the Scottish Wildlife Trust were also involved in opposition to the project.

The rejection on 21 October follows 11 years of debate over whether the economic benefits of a new championship golf course could justify development on one of the Highlands’ most environmentally sensitive stretches of coastline.

For the second time, Scottish ministers have decided they cannot.
