OPAL Air Survey


Help scientists learn more about air quality across England
Record lichens on trees and look for tar spot fungus

The OPAL Air Survey needs citizen scientists to record lichens on trees and look for tar spot fungus on sycamore leaves. By contributing, you'll help scientists answer important questions about local air quality and its impacts across England.

Even if you haven't fond any lichens or tar spots, your findings are still extremely useful. Each activity should take no more than 60 minutes.

This is one of five OPAL surveys across England to learn more about the state of the environment. Anyone can get involved. The studies are open to all ages and abilities, and your contribution will be important in helping scientists build up a picture of England's natural environment.
