Lichens in Barcelona

Inici » Lichens in Barcelona

Lichens are peculiar, highly-resistant organisms: they can live on rocks and thrive in extreme climate and weather conditions. They are very sensitive to increased concentrations of pollutants, which makes them excellent bioindicators, natural air quality monitors. A city's lichen map shows its quality and allows it to be monitored over time. The general public participate in mapping lichens in Barcelona, working with experts to identify species, recognise them and be able to interpret them. The data gathered are entered into the Natusfera platform. Once they have been checked, they are transferred to the GBIF global biodiversity platform.
