Lichen Participatory Survey — Usnea sp.

Lichens are very good bio-indicators which, depending on the species, can inform, among other things, the age of forests, air quality and the effect of climate change at local level. As part of a participatory survey launched in autumn 2015, 6 species and 2 species groups were selected to be particularly revealing while remaining easy to identify.
Dataset under the survey set restricted to lichens ‘Usnea sp.’
