Diseases
Woodlands, like all living environments, can be affected by plant and tree diseases — some spread naturally, while others are introduced from elsewhere — so we work to monitor, manage, and protect the woodland to help keep it healthy for future generations.
Larch Disease
Larch disease, caused by the fungus-like organism Phytophthora ramorum, affects larch trees and can spread quickly through woodlands. It causes the needles to wilt and blacken, and eventually leads to dieback and tree death. To prevent it spreading, infected trees often need to be felled and carefully managed, which can change how parts of the woodland look for a while. Although it’s a serious disease, woodlands are resilient — new planting and natural regeneration help restore balance and encourage a healthy mix of tree species for the future.
Ash Dieback
Ash dieback is caused by the fungus Hymenoscyphus fraxineus and affects ash trees across the UK. It leads to leaf loss, branch dieback, and can eventually kill the tree. Careful management, monitoring, and natural regeneration help ensure the woodland continues to thrive for wildlife and visitors alike.
Woodlands are full of life, but trees can be affected by a variety of diseases and pests that we need to be aware of. Different species are susceptible to different problems — for example, oak trees by issues such as acute oak decline.
Acute Oak Decline (AOD): A bacterial disease that causes dark, weeping lesions on the bark and can lead to rapid tree decline. Often affects mature trees, especially in southern England.
Oak Processionary Moth (Thaumetopoea processionea): The caterpillars feed on oak leaves, weakening the trees and producing irritating hairs that can affect humans and animals.
By keeping an eye on the health of all the trees, managing risks responsibly, and encouraging a diverse mix of species, we help the woodland stay resilient and continue to provide a thriving habitat for wildlife and a beautiful place for visitors to enjoy.
