Air survey - what have we discovered so far?

With more than 2,000 air surveys submitted, some exciting results are beginning to emerge.

Lichen expert Pat Wolseley from the Natural History Museum has taken time to review all your results so far, and has made some interesting findings.

Most notably, it appears that nitrogen-sensitive lichens are returning to urban areas, such as London and Birmingham, where they were once absent due to high air pollution.

By looking at the results maps you can see this and other interesting findings for yourself. You will also notice obvious patterns such as cleaner air in coastal and remote areas. These patterns are to be expected and give us confidence in the data being collected.

New ways to analyse the air survey results
You can now find pollution score maps and lichen diversity maps in the air survey results section.

Pollution scores give a quick indication of the local air quality. You’ll notice higher scores (cleaner air) in coastal and more remote areas.

A variety of lichens growing together can be a sign of good air quality. Compare lichen diversity across the country on the lichen diversity score map.

Submit your air survey results

We are still collecting your air survey results. The more results we receive, the more valuable and informative our findings will be.
