News and media News items [10.02.18] Replacing Ash: Appropriate Tree Selection Devon is likely to lose the majority of ash trees due to the spread of ash dieback disease. This note provides guidance on which tree and shrub species should be encouraged, through planting or natural regeneration, to replace lost ash. The aim is to ensure a resilient landscape – one which can cope with current and future threats while remaining attractive, functional and rich in wildlife. There is no one tree that can replace ash. Aspen, sycamore and elm are the closest match. It is strongly recommended to plant a rich variety of species of trees as this will better fit the ecological void that loss of ash will create. It will also provide a far more resilient and viable landscape in the face of the many tree diseases that threaten our landscape. Download this leaflet on Replacing Ash for more information.
