In March it was revealed brown bears could be making a comeback to English woods.
A £5 million ($6.6bn) project aims to reintroduce the animals to a seven-acre site on the outskirts of Bristol – complete with a treetop walkway for visitors to look down on them.
The scheme, called Bear Wood, would see Eurasian brown bears – which can grow up to 8ft tall – rearing their cubs exactly as they did in medieval England.
But the creatures would not be left to roam totally wild – they will be safely fenced in and keepers would supplement their foraged diet to keep them well-fed.
Bristol Zoological Society has already received donations towards the cost of the project, but it needs to find an extra £2 million ($2.6m).
All of the buildings will be constructed to blend in with their surroundings, Bristol Zoo said.
And if the plan was not already ambitious enough, five European grey wolves, already at nearby conservation park Wild Place Project, will be moved to a new home in Bear Wood.
