Unfortunately for the author David Waterston 92 years later, both the Maritime Pine and Sea Buckthorn are considered to be invasive species, as is gorse. The Links or Dunes habitat consist mainly of grasses and herbs and often have SSSI status.
In Southerness they have a compaign to removing Seabuckthorn and I believe recently at Nairn some old pine trees were removed with approval of the environmentalists.
However with global warming and the wish to find places to plant trees, the Links courses may have to do there bit.
Scotland has plenty of room for planting trees in the highlands, as long as the deer are dramatically reduced in number.
However will the weekend hunters, up from London, be prepared to sacrifice their fun for climate change?
