The animals first arrived at the Burscough centre in July 2007 and they have certainly been busy since then, building an impressive lodge and tunnel network.
One Show presenter Mike Dilger will be at the centre as attempts are made to drive cameras through the tunnels to see just how much work the beavers have done.
Centre manager, Nick Brooks, said: “Everyone at the centre is very excited to get a glimpse of the tunnel network the beavers have created – we know it is extensive based on the number of holes but we don’t know how intricate they are.”
Families will be able to learn more about the beavers during a drop-in session next weekend as part of a two-day Animal Magic event.
The sessions run from 2.45-3.30pm on both Saturday, September 21 and Sunday, September 22, amid the animal-based fun.
Representatives from the centre and a number of local animal organisations will be at the event.
Organisations in attendance will include the Greyhound Rescue Society, North West Reptile Club, Cats Protection League and Lancashire Badger Group. There will also be staff from the Bolton Ferret Rescue Society and Beekeepers Association.
Families will be able to meet hedgehogs from Freshfield Animal Rescue, pigs and ponies from Windmill Animal Farm and birds of prey from Corio Raptor Care.
They can take a closer look at alpacas, meerkats, parrots and reptiles with Jungle Talk. And there will be a range of activities on offer, including pond dipping and den building, as well as the usual walks, talks and canoe safaris.
Animal Magic which runs from 11am-4pm, is included in the admission price.
