Lichens GO is a participatory program born in 2017 in a co-construction approach for both the protocol and the identification key performed with volunteers from the Lyon region, the French Association of Lichenology (Marc Boulanger, Nicolas Malle, Chantal Van Haluwyn, and Grégory Agnello), PartiCitaE (Laure Turcati), and Vigie-Nature École (Sébastien Turpin, Simon Bénateau, and Vincent Chassany). A data entry interface was proposed in 2019 by Tela Botanica. The protocol and the identification key were reworked in 2022 in the light of research performed at UCLouvain (Yannick Agnan and Hugo Counoy) and based on feedback from Cécile Lambert and Françoise Peyrissat. A new data entry including the result visualization was proposed in 2023.
