The search is on to find trees planted in Wales in memory of soldiers who died in the longest single battle of World War One.
As the 100 year anniversary of the battle of Verdun is marked, the Woodland Trust is looking for volunteers to trace the oak trees from France.
The trust said it had found some clues as to where the trees may have been planted but needs more help.
