Introduction to General Reports

This General Report allows you to report any suspected tree pests and diseases affecting the health of a tree anywhere in Great Britain.

We are grateful for every report that we receive and the time taken to complete them. To make the most of your tree health submission you will be taken through a series of screens where you will be asked a number of questions about your observation. The more details you can provide, the more informative your report will be.

These questions are designed to provide the Forest Research diagnosticians with high-quality, complete information to support the triage of your report. This helps them reach the most accurate diagnosis and provide relevant information about your tree health submission.
