It must be the ultimate endorsement.
For if Cley Marshes nature reserve's bosses were brainstorming the best names to back them, Sir David Attenborough would surely be at the top (and probably second and third, too).
Now He has done just that, naming the north Norfolk beauty spot as one of the great places to see wildlife in Britain.
In an article written for a national newspaper in which he revealed his five favourite spots for wildlife lovers in the country, Sir David also praised Norfolk Wildlife Trust for its management of Cley Marshes.
'It is one of the great places in Britain to see wildlife,' he wrote in the Telegraph. 'The Norfolk Wildlife Trust was the first in this country, founded in 1926 – the year I was born.
'Twelve friends produced the money to protect this coast, at a time when natural history was regarded as something slightly odd. Today, these trusts are a national movement, and it's heartening to know that there's not a square yard of this country that doesn't have a trust caring for it to some degree.'
Sir David, however, cautioned that the coastal reserve would increasingly come under pressure from issues such as climate change.
'As the world warms, there will be extreme things happening to this coast, and we need people who understand it and will look after it – not just for ourselves, but for the wonderful creatures that live on it.'
Chief executive of Norfolk Wildlife Trust Brendan Joyce said: 'We are delighted Sir David loves Cley Marshes and this was apparent when he came to open our Simon Aspinall Wildlife Education Centre in 2015.
'We are already witnessing the effects of climate change at Cley and have seen an increase in the frequency of sea floods and changes in the habitats.
'It is vital we protect and manage these special places as best we can and that we raise awareness of the fragility and needs of wildlife. Many species are under threat as a result of climate change and need our help if they are to survive.'
Cley Marshes is the trust's oldest and best known nature reserve. It supports large numbers of wintering and migrating wildfowl and waders, plus bittern, marsh harrier and bearded tit.
