Backpack-wearing dogs enlisted to rewild urban nature reserve in Lewes

Organisers hope dogs will mimic behaviour of wolves that in past would have helped disperse wildflower seeds

Backpack-wearing dogs are being enlisted to act like wolves" to help rewild an urban nature reserve in the East Sussex town of Lewes.

Before wolves were persecuted to extinction in the UK in about 1760, they were known to roam large areas, typically covering 12 miles (20km) or more each night.
