A bid has been launched to protect and extend the Lake District’s rainforest.
Borrowdale is classed as a temperate rainforest – among one of the oldest habitats in the world – and the National Trust and Natural England want the area declared as National Nature Reserve.
Woodlands in Borrowdale form the largest remaining piece of England’s native rainforest.
The National Trust said: “In a valley famous for its rainfall, it is every bit as wet as a tropical rainforest and is its equivalent in our cooler, temperate climate.
“The proposed declaration is a testament to the increased focus on caring for this significant habitat while celebrating the impact the unique landscape here has had on the natural and cultural heritage of the Borrowdale Valley.”
The scheme would start with 735 hectares and plans include reconnecting parcels of woodland to create wildlife corridors and improve the resilience and overall health of the forest.
It said that in time and in consultation with farmers and local landholders, the reserve would grow to include other vital areas of woodland.
The trust added: “Fell farming is an integral part of Borrowdale’s cultural history, and this has helped to shape the land and the people within it.
“To ensure the success of the project and the best outcome for the valley, the National Trust is consulting with and working alongside local farmers, many of which are already doing important conservation work.
“Helping them access payments for their efforts will be an essential part of the management of the NNR and the surrounding land.”
Jade Allen, National Nature Reserve Officer, said: “We are incredibly excited for the launch of our new Borrowdale Rainforests National Nature Reserve project.
“This project is a big step towards protecting an enhancing the incredibly special rainforests of Borrowdale.
“Our hopes for the future are for the woodlands to be thriving and regenerating, for the biodiversity within these woodlands to be improving, and to start
reconnecting the woodland fragments for a more viable ecosystem.
“By working with our local farmers and community we are looking forward to better connecting people with the woodlands, nature, and history of Borrowdale.”
The National Trust and Natural England said they were working through the application and a decision was expected in the spring.
