Lichens OPAL workshop

Good air quality is essential for our health and for the well-being of our environment. Lichens can be helpful indicators of air quality.

By taking part in the OPAL Air Survey you can find out about air quality near you and help our scientists answer important questions about the impacts of air quality across the UK.

The Open Air Laboratories (OPAL) network is a UK-wide citizen science initiative that allows you to get hands-on with nature, whatever your age, background or level of ability. The surveys explore the health of our soils and trees, the quality of our air and water, the distribution of invertebrates, the importance of hedges, and the ways in which we affect our climate.


Advance booking essential.
