That’s the thing about ponds. They are ephemeral and require regular management to retain their species diversity. People are all for making them, but often that’s as far as they go, and they eventually silt up. The local wildlife trust has or had one that was at one time a beautiful habitat, a jewel I suppose one could call it, at its HQ garden. The last time I saw it, it was a shadow of what it once was. No one in the office seemed keen to clear it or maintain it, as it was not in their job description. FFS was all I could think of.
