Indicator values for lichens on Quercus as a tool to monitor ammonia pollution in Denmark
Research output: Contribution to journal › Journal article › Research › peer-review
The epiphytic lichen vegetation on solitary Quercus trees was investigated
on 13 locations in Denmark in order to test the usability of indicator
values to quantify ammonia deposition from the ambient air. Indicator
values calculated for each location corresponded well with the expected
ecological conditions. The indicator values for nitrogenous nutrients significantly
correlated with measured nitrogen content in Xanthoria parietina
thalli sampled from the investigated Quercus trees. Indicator values for
some species are critically evaluated, and it is suggested that indicator
values can serve as a tool for quantitative estimation of ammonia deposition in relation to sensitive Danish ecosystems.
