The UK is at risk of losing millions of trees to pests and diseases.

Observatree is a tree health early warning system to help us spot and report outbreaks of tree pests and diseases quickly so they can be eliminated or controlled.

It relies on a network of almost 200 trained volunteers and tree health professionals who survey and check trees throughout the UK.
