Urban areas are not all high-rise flats and offices, they are also where you’ll find many of the country’s trees.
Two London boroughs – Camden and Croydon – were among the top 20 places in England and Wales with the most tree cover, a research project has found.
Meanwhile largely rural areas had some of the least – including part of the Lake District and the Yorkshire Dales.
Garden trees are boosting numbers in towns, while farming helps explain some of the low rural rankings.
Bluesky International, an aerial survey company who carried out the work with the help of mapping specialist Esri UK, say they have detected around 400 million trees so far – but there are still more to find.
