Lichens in a changing pollution environment (ENRR525)

This volume presents the results of a workshop on Nitrogen in the Environment held at the Field Study Centre at Nettlecombe Court, Taunton, Somerset from 24-27 February 2003. A changing pollution environment across Europe has led to concern that increasing levels of nitrogen compounds are now affecting lichen communities in both urban and rural environments. Interest has focused on two main aspects, the use of lichens as bioindicators and potential threats to lichen species and their communities. Concern within English Nature that nitrogen may affect lichen-rich sites of conservation importance led to the provision of funding to the British Lichen Society to run a workshop to address these issues and to make recommendations for further work. The workshop was organised from the Natural History Museum, London, and the grant allowed us to bring together specialists concerned with nitrogen from five European countries.
