Observatree, early warning system for tree health

This multi-partner project pulls-together tree health research and expertise and combines them with trained volunteers and educational resources to help people to identify and report a selection of important tree pests or diseases. The Observatree volunteers have reported significant pest and disease findings and they help to support tree health scientific studies and targeted surveys. The highly acclaimed pests and diseases identification guidesvideos and other resources that underpin the volunteer training are used and promoted by professionals; they are freely available from the Observatree website. The website hosts regular blogs, and the project producesa quarterly e-newsletter that can be subscribed to. Observatree volunteers submit their tree health reports through TreeAlert, an online system that can be used by anyone to report suspected tree pests or diseases.

TreeAlert is the official tool used to gather information about tree health issues across Great Britain. Information on unhealthy trees submitted through TreeAlert is reviewed by tree health scientists at forest Research, who will attempt to diagnose the cause of the problem. This information supports important tree health monitoring and surveillance work, contributes to ongoing scientific research, and helps to protect the nation's trees. TreeAlert is available for anyone to use. A Tree Officer role is available under the ‘Client Affiliation’ (part of the data submission process) that will help to identify enquiries submitted by Tree Officers.
