Initial work on Donald Trump's £1bn project to create what he has vowed will be the world's greatest golf experience has got under way.
Donald Trump Jnr - the son of the American billionaire - was at the Menie estate, north of Aberdeen, to see work start on the dunes.
It includes the laying of special marram grass, earthwork and fencing.
The Tripping Up Trump group has warned it would take legal advice over Tuesday's decision to approve the work.
Aberdeenshire councillors on the Formartine Committee gave the go-ahead for the preparatory work to be carried out to stabilise the shifting sand dunes around what would become the championship golf course Mr Trump wants to build.
A masterplan for exactly what is planned for the estate is expected to be ready for submission next year.
Mr Trump Jnr told BBC Scotland of the work starting on Wednesday: "This is a long-term project, it's one component of many that is getting under way.
"We are trying to deliver the greatest golf course anywhere in the world, we believe we have the land to do that, we believe we have the team to do that. Golf has been a major passion for my father."
He explained: "There have been a couple of detractors that don't want this to go forward. It's getting ridiculous and childish. We have been under incredible scrutiny. That will never be enough for some of the extremists.
"I think maybe the stunts we have seen will be their last hurrah.
"Others we have incredible relationships with. The vast majority of the people of the north east want this project to go forward."
Efforts are still being made by the Trump Organisation to buy a handful of properties on the site, but the owners have been refusing to sell.
A council committee originally rejected the proposal for the development.
The proposal was later called in by the Scottish government, and approved.
