UK Nature and Environment

I have just made myself very popular with a local social housing company: I've brought to their attention, for the second time in about the last ten years, the miserable condition of a tiny strip of land at the end of one of their roads. It's no more than 3m by 2, and has a grassy bank and small trees, all planted by Nature. In spring the bank has primroses all over it, except that's not been so obvious since people started using it as a rubbish tip. It used to be OK, and so pretty. I've come to realise there's some obscure psychological reason for people going out of their way to screw up bits of natural terrain, so what can the housing company do? I've asked them why they don't just check the surroundings of their properties every so often and give them a quick clean-up. 🌸 😢
