On Saturday 13th of November 2021 a small group of Citizen Scientists visited the Rivers Orchard area site to survey lichens as indicators of air quality.

All the trees had a quite remarkable lichen flora, in some cases there with six species present on one branch. All the lichens identified are Nitrogen Dioxide and Acid tolerant which tells us that the air quality in the is area is quite low. Pictures from GL.

Generally easy walking but can be slippery and muddy on the arable land. Recommended to avoid busy scho...
