What’s happened here?
In 2015, as part of our continuous tree monitoring programme, Westonbirt staff identified Chalara ash dieback within Silk Wood. This is a disease that has been sweeping across Europe since 1992, which kills ash species.
This area is part of our response: a fightback to ensure a healthy, diverse and resilient woodland in the future. 2021 saw the start of major work to remove ash trees.
This is a highly managed approach which includes three management techniques:
- Clear fell and replant areas with large numbers of infected ash trees.
- Thinning, which leaves unaffected trees and removes only ash. This leaves spaces for natural regeneration of other species.
- Non-intervention, which allows us to research the effects of the disease.
