The Dutch engineer Cornelius Vermuyden cut the New Bedford River parallel to the Old, creating a corridor between them — 32 kilometers long and roughly a kilometer wide — that could deliberately flood when the Great Ouse ran high. Nobody called it a wildlife reserve. It was an overflow valve for a river system serving drained farmland. But the animals arrived anyway, and they have not stopped arriving since.

In 1630, King Charles I granted a drainage charter to the 4th Earl of Bedford and his Adventurers, who set Vermuyden to work on the Old Bedford River between Eari...

The surrounding ditch network, surveyed as part of a Heritage Lottery Fund partnership that ran from 2014 to 2017, turned out to harbor astonishing invertebrate life. More than 100 water beetle species were...
