nostr:npub1m64s8kyz08q9qkx33spy3276am3tnmzyfs85u8308d0q92qywukqh44th4 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.
