Open Air Laboratories (OPAL) Air Survey - Lichens
Dataset
Documentation
Description:
Since 2007, OPAL's citizen scientists have collectively built a wealth of environmental data. To ensure that this rich source of information may continue to be used by researchers and the wider public, spreadsheets containing data for OPAL's core UK-wide surveys can be downloaded using the links on this page.
The OPAL Air Survey allows participants to find out about the air quality in their local area and across the country, and discover how the natural environment is affected by air pollution. It uses ‘bioindicators’, species whose presence or performance is sensitive to changes in environmental conditions. The OPAL Air Survey contains two activities, using different bioindicators of air pollution.
Activity 1: Lichens on trees
The survey recorded the abundance of nine different types of lichen growing on trees. This provided a bioindicator system for nitrogenous air pollutants, by including lichens that are nitrogen-sensitive (declining where pollution is high), nitrogen-tolerant (increasing where pollution is high) or intermediate (no strong preference).
