How re-wiggling artificially straightened rivers can give nature a boost.
The meandering waters at Swindale Beck now provide important habitats that had been missing for centuries"Nature needs chaos, it needs randomness," says Lee Schofield from the RSPB.
That had unintended consequences. The faster-flowing water was too swift for fish like salmon and trout to spawn. And the river carried more sediment downstream, making it murkier. After studying the valley to locate the original path carved out by the river, the charity enlisted a team of diggers to recreate that curvy channel. It is now about 180m longer than the straight line that had been in the valley bottom for two centuries."About three months after the diggers left - we had salmon and trout spawning in the river again," he recalls.
"It's like a living thing moving through the valley now, while the old, straightened river was just like a sad canal."This restoration was expensive. Funded in equal parts by the RSPB, the Environment Agency, Natural England and the water company landowner, United Utilities, it cost just over £200,000 to rewiggle the 1km stretch.
"Last year's Landscape Recovery pilot was massively oversubscribed," she says. "The Government should move swiftly to bring sufficient funding online to match the demand for those groups of farmers and landowners wishing to deliver for nature, climate and water quality."
