Plans to reintroduce the Eurasian lynx 1,300 years after it became extinct in the UK will be submitted soon, campaigners have said.
The Lynx UK Trust hopes to obtain six lynx from Sweden to reintroduce into the Kielder Forest in Northumberland.
The five year plan plan may go to Natural England by September.
It has been criticised by some residents and sheep farmers.
The scheme would see four to six lynx wearing radio tracking devices introduced, with Kielder chosen due to its dense woodland and low number of roads.
The trust said the animals would help control deer numbers as well provide a tourism boost.
Although farmers will naturally protest, I can't see the Lynx making much of an indent in sheep numbers, and I'm pretty sure they would get more than adequate compensation for their losses. They usually do.
