New field guide for using a lichen-based index to nitrogen air
7 October 2013
A new field guide for using epiphytic lichens
to assess atmospheric nitrogen pollution effects on habitats has
been published. This is based on research co-funded by JNCC
in partnership with Sniffer (on behalf of
the Scottish Environment Protection
Agency and the Northern
Ireland Environment Agency) and the Centre for Ecology &
The guide will enable specialists and non-specialists to
determine air quality, with respect to concentrations of ammonia
and oxides of nitrogen, by using common, easy to identify, lichen
species to calculate an air quality index for a site.
