Tree A!ert - disease sighting reporter

Britain's trees are under unprecedented threat from new pests and diseases. We are particularly interested in identifying problems with Ash, Oak, Pine, Spruce and Horse Chestnut trees. You can help by being aware of the symptoms of serious threats and reporting them for further investigation using this form or our Tree Alert app if reporting Chalara ash disease.

An App for reporting pests and diseases is also available.

These details may be used to allow us to get in touch with you should we need to investigate your report further or to notify you about updates.

We give priority to reports which include pictures (taking great pictures):

Uploading large images may be very slow. Please be patient or try with a single image.
