These are beautiful Bjørn!
Trees around the farm are very normal in our climate as well. The trees that stood around the yard were mostly the Walnut, Elm , Ash , Poplar and Willow , all had their double function. They stood there for show, they kept the buildings - especially the vulnerable shed with thatched roof - from the wind and their wood was used for functions in a wide range . Walnut (and Chestnut as well) for the fruit, insect free for the cattle and people, and wood for all kind of tools, Elms for farm wagons , Ash as shank and grips for tools, Poplars as fuel and floors and against lightning , Willow as burning wood and medicine for the cattle. Usually these trees were combined with a number of different fruit trees.
These will grow more easily in our climate than in Northern Norway, I guess
