@deab03d8 Walnut trees are a protected species here. They've been massively cut down due to the wood being great for furniture. I also remember a case of local corruption ... the mayor of a town cut down the walnut trees from an entire street between 2 cities (30 km). Those trees provided shade and were cut down presumably to expand the road, just before the protection law passed.

Anyway, you're doing the world a favor for growing walnut trees.
