Also, as far as I remember it was a nature reserve too. and because it was divided into thousands of tiny plots it would be near impossible to buy the whole land and destroy the forest.

You only “own” that plot of land in that company’s register. If they even keep that. As far as Scottish law goes, the entire land is just one plot, owned by the company.

It’s illegal to sell such small plots, so it’s literally impossible to actually, legally, purchase a plot of land that small.
