Close to where I live in Brighton there is a park called the Level. It’s surrounded by trees, some of which are elms. Elms are very rare because of Dutch elm disease, but Brighton has the largest elm population in Europe. Last week several of the Level elms were found to have the disease. This happens from time to time but it is always a shock. It’s a fungus spread by a beetle. The trees are all interconnected by their roots. The council’s tree team have been working to save the rest of the elms —six of them have been felled. I went to the trees on Global Earth Exchange day and sat with them. Here is a photo of flowers and a letter on top of one of the elm tree stumps.
