Why do oak trees sometimes look like they’re weeping?

Acute Oak Decline (AOD) is a serious condition affecting oak trees, predominantly in the United Kingdom. It is characterized by the presence of dark, weeping patches on the trunk and branches, accompanied by significant decay and dieback. AOD is caused by a complex interaction between bacteria and insects, which weaken the tree's defences.

Prevention of AOD primarily involves good woodland management practices. Implementing measures like maintaining tree vitality, avoiding unnecessary wounds, and promoting biodiversity can help minimise the risk of infection. Timely detection and reporting of affected trees, followed by appropriate tree care and management, are crucial for mitigating the impact of AOD and preserving these majestic trees!
