A “labour of love” he says, this is a collection of the locations of unique trees which are candidates for Heritage Trees from the Treefest Scotland web site. You can download the Heritage Tree collection 
and see these wonderful trees yourself. Each placemark has the name of the tree, information about the tree-type, a photograph, and usually links to more information. I never realized the amazing diversity of tree types in Scotland. It’s unfortunate that most of Scotland only has low-resolution sateliite photos so you can’t actually see the trees themselves.
The author of this nice collection of placemarks is a Bob Fleet from Scotland, known as ‘fleetpeople’ at the Google Earth Community. Here is his post for the collection.
