Relationship between atmospheric ammonia concentration and nitrogen content in terricolous lichen (Cladonia portentosa)

Research output: Research - peer-reviewJournal article

From April 2006 to April 2007, the geographical and seasonal variation in nitrogen content in terricolous lichen (Cladonia portentosa) and atmospheric
ammonia concentrations were measured at five heathland sites. The seasonal variation in the nitrogen content of the lichen was small, even though there was a large seasonal variation in the air concentration of ammonia. A sizable local variation in the nitrogen content of the
lichen was found even at the scale of a few kilometres.
The nitrogen content in the lichen showed a high correlation
to the yearly mean value of the measured ammonia
concentration in air at the different locations. This
investigation is part of a larger attempt to incorporate
effects of nitrogen in the conservation status of terrestrial
habitat types.
