In cumbria, the northern slopes of some valleys are covered in junipers. The berries smell great. But it wasn't for the gin that they were planted. Apparrently (according to a lecturer of mine way back near the beginning of my learning) the charcoal made from juniper is very fine and a favourite of the gunpowder makers. For some geological reason not yet discovered by me, the slate mines are all on the south facing slopes. They used the gun powder from the north-facing slopes juniper for their blasting.
