Ulmus Londinium

Identifying London's remaining elms and providing new trees for the capital.

The Heritage Lottery Fund is helping us launch a major survey throughout London. It will involve London Tree Officers and Tree Wardens along with enthusiasts and schools. We will provide help to those who want to know more about identifying elms and stage workshops for experts and enthusiasts to meet and have elm leaves identified.

Why are we doing it?

"Many people think all the elms have gone, killed off by Dutch Elm Disease in the 70s, but we know of quite a few mature, healthy trees and there could well be many more," said David Shreeve, director of The Conservation Foundation. "There are many elms growing here from around the world... some of these could well have a resistance to disease which would enable them to be used in future propagation experiments," said David.

As well as being the sole source of food for some rare species like the White-letter Hairstreak butterfly, elms have also been used extensively by humans. London's first water pipes were made of elm, and Old London Bridge stood standing for six centuries (despite the nursery rhyme!) with the help of elm wood piles in the River Thames. Find out more from our London Elm Heritage map or by viewing the A to Z of London's Elms video.

Plot the capital's elms

The Foundation hopes to create a comprehensive guide of surviving elms within the M25, so if you spot one, add it to our map.
