Abstract:: London's lichen and bryophyte diversity has greatly improved following major reductions in SO2, but the species composition appears to be dominated by 'nitrogen-loving' taxa. The review and assessment of London's Air Quality confirms that oxides of N from traffic exceed both the protective standards for Sensitive Ecosystems and Vegetation and Human Health. This study will for the first time critically examine the relationship between corticolous lichen and bryophyte diversity and various atmospheric parameters based on the proposed EU lichen recording method. Multivariate statistical techniques will be applied and GIS maps constructed to examine the relationship between individual pollutants and other factors, necessary towards establishing practical indicator scales to monitor the effects of the new pollution climate.
