Lichens GO
Assess air quality in urban and rural areas
Lichens GO is a citizen science program that aims to assess the air quality around your home by studying the different species of lichens that grow on trees. These organisms having a slow growth, they indicate a level of pollution accumulated over several years, which makes them complementary to measurement sensors.

With the data collected in the field, you will be able to participate in the air quality mapping in your city. In addition to contributing to scientific research, it is an opportunity to learn more about air pollution and its impact on biodiversity.
Lichens GO is an observatory of PartiCitaE (Sorbonne University) and Vigie-Nature École (National Museum of Natural History). It is offered in partnership with Tela Botanica (as part of the project Auprès de mon arbre), UCLouvain., and

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.
PartiCitaE is a participatory observatory of the urban environment. It questions, with city dwellers, the human influence on urban environments and ecosystems with the aim of improving living conditions in the city for all living beings, including humans. The main theme of the observatory concerns air quality, which results in particular in the coordination of three projects: Lichens GO, Écorc’Air, and ExpoPed. PartiCitaE is also interested in the biological quality of urban soils with the QUBS observatory
