This guide provides a simple method for determining gaseous nitrogen pollution that can be used by anyone interested in the impacts of gaseous N on sensitive habitats in the UK. It includes a simple identification key to epiphytic lichens growing on oak and birch that show sensitivity to, or tolerance of, atmospheric N pollution. The lichen species present at your location are used to calculate a lichen indicator score (LIS), which is then converted into a standardised nitrogen air quality index (NAQI), showing the nitrogen air quality at your location.

This is just one of the FSC's range of fold-out charts, designed to help users identify of a wide range of plants and animals. Each chart is laminated to make it splashproof and robust for use outdoors. Clear colour illustrations and text by experts in the subject make these valuable resources for all age groups.
