The group is asking for islanders to help gather the data. Responsibilities would include identifying trees from online maps and images and finding them on foot.
The tree recorders will then use an app to plot the locations against GPS co-ordinates, recording the species, locations, size and condition.
Organisers of the survey say some tree knowledge, and the ability to identify different species is needed, but training will also be provided.
Jersey Trees for Life is seeking volunteers for this project, but there is also a paid coordinator position available.
