Ash dieback and the health of English trees
Threats to UK trees have risen due to factors such as globalisation and climate change. The government has responded with a tree health resilience strategy, an England trees action plan and an updated plant biosecurity strategy. However, certain pests and diseases remain high-risk, including ash dieback. Several organisations are seeking to breed ash trees that are resilient to the disease and the government has published a strategy for preserving ashes.
