‘Air Pollution and Citizen Science – Lichen Identification Walkshop’
September 12, 2017 @ 6:00 pm - 7:30 pm
Lichens are formed from a symbiotic relationship between fungus and algae, and grow everywhere! There are many different types of Lichens and some are sensitive to levels of Nitrogen Dioxide (NO2) in the air, therefore acting as bio-indicators of pollution levels. Carrying out a Lichen survey is a fun and engaging activity to explore and understand more about your local area. It is suitable for all age groups, including families. We will also bring our Particulate Matter monitor and take readings with that along the way (which may excite older children and those more interested in technology). It will begin and end with short presentations and discussions about pollution. This walkshop is in collaboration with Croydon Communities Consortium.
