I had an elderflower tree in my garden. I didn't plant it, it just arrived, and grew, and flowered, and provided perches for birds waiting to use the birdbath and nibble at the nuts and seeds in the birdfeeders.
Now it's gone. Without saying anything to me, my neighbours have chopped about 2/3 of it down (the branches that were overhanging their garden), plus they have radically pruned the ones on my side of the fence. Now they are burning it up slowly on their wood-burner stove right underneath my window.
There's nothing I can do about it, is there?
