Pupils from Nottingham Girls High School have used the OPAL air survey to help them achieve their British Science Association (BSA) silver CREST Award.
CREST is Britain’s largest award scheme for project work in science and technology. They are widely recognised and can be used to enhance college and university applications.
To gain their award, Year 10/11 students designed independent projects to explore the effect of nitrogen oxide pollution on lichens.
Using the OPAL air survey field guide, they recorded the distribution and abundance of key lichens on oak, ash and sycamore trees, and compared the results across different sites.
Amongst other things, they discovered a gradual change of lichen distribution from Nottingham city centre into rural areas.
Nitrogen-loving lichens such as Xanthoria were common in the city, while nitrogen-sensitive lichens such as Usnea were found in increasing numbers moving away from the city.
