Sir David Attenborough has put his support behind an urgent appeal for funds to secure the long-term future of Attenborough Nature Reserve in Nottinghamshire.
The reserve has been under the care of local charity Nottinghamshire Wildlife Trust for almost 60 years.
Now, the charity has a rare chance to purchase the site.
Attenborough Nature Reserve covers 200 hectares of wetland, woodland and grasslands habitat on the site of a former sand and gravel quarry.
Sand and gravel extraction at the site ended in 2017 and the Wildlife Trust have agreed to buy the land from its owners.
As a result, the £1 million Attenborough Nature Reserve Lifeline Appeal has been launched to ensure the Trust can purchase the site and invest in its future management.
Sir David is President Emeritus of The Wildlife Trusts.
Speaking in support of the appeal, Sir David said: "Attenborough Nature Reserve is a symbol of hope in a challenging world.
It is a natural oasis on the edge of a big city, full of remarkable and beautiful birds and other wildlife.
Please give as generously as you can to help us make sure this place is forever safe in the hands of Nottinghamshire Wildlife Trust."
