The World Owl Trust say their current agreement with the estate managers is being terminated and unless they can negotiate new arrangements, they'll have to leave by May 2015.
The charity claims the new terms are not financially viable, but the estate say negotiations are ongoing and in tough financial times it's having to review the way the owl centre is run.
The Muncaster estate says it's willing to negotiate but the Trust says it's looking for new premises. Honorary President Tony Warbuton said: "the owl trust is looking for somewhere new to be based, we do not feel we are wanted anymore at Muncaster."
The World Owl Trust, which is based at Muncaster Castle in Cumbria, is urging people to grow their grass to help the Barn Owl. The population has plummeted in Britain due to a loss of habitat and the Trust say 'welly high grass' will help boost numbers. Hannah McNulty went to find out why.
An event aimed at raising awareness about owls and how important they are is being held by the World Owl Trust at Muncaster Castle.
They will be offering information on how to help owls living around the region and will be asking hoteliers to allow their grass to grow long, which will encourage young animals into their gardens- providing a vital source of food for owls.
"Our Conservation Day is a great opportunity for people to come and see the kinds of things that they can do to make a real difference in helping see owls thrive in their area."
– Millie Clarke, Conservation Officer, World Owl Trust
The owl trust centre is home to more than 200 owls from 50 different species and sub-species.
