Native oak trees – keystone species in our woodlands - are under threat from Acute Oak Decline (AOD). The disease is increasingly affecting mature native oak trees across Britain, causing rapid decline and death within as little as 4-5 years. We are seeking help from woodland owners and managers for an important new research project aiming to monitor the health of oak trees across the country. We want to capture the current health of oak trees so we can make comparisons between affected and symptom free woodlands. We hope to understand the differences in environment, underlying health of the trees and importantly the role of management in improving outcomes.

AOD can be diagnosed by a depleted oak crown, black stem bleeding, and D-shaped exit holes (left by the Agrilus biguttatus beetle). The disease can seriously diminish health and resilience of infected trees, for example by making them more susceptible to honey fungus. AOD can spread within a woodland once introduced and exacerbate existing stresses.

Sylva Foundation is working closely with scientists from Forest Research and Aberystwyth University to understand more about this devastating disease. We are looking for volunteers to assess five or more oak trees, between June and August. Using a purpose-built web app, you will help by assessing each oak tree which should take no more than 5 minutes. The data will then be shared with researchers via Forest Lab.
