TreeWatch was developed by the Sylva Foundation as a 'citizen science' project that enabled members of the public to report on tree health, and which aimed to act as an early warning system for pests and diseases. It ran from 2010 to 2013.
If you are keen in taking part in tree science activities, there is some good news. Help us identify healthy ash trees as part of a nationwide effort to combat the threat from Chalara ash dieback called the Living Ash Project.
