Bryophyte distribution in Wallonia shaped by air pollution, background environment, pesticides and heavy metals

appendix 1 includes local species frequencies of all epiphytic bryophytes at 20 stations where atmospheric pollutants are measured in Wallonia + mean and annual maximum pollutant concentrations (including heavy metals) + phorophytes species + climatic and topographyic data + forest cover data, for the period 2016-2020 at the station. appendix 2 includes a complete inventoires of all epiphytic bryophyte species recorded after 2016 in 43 16km2 pixels + mean and annual maximum pollutant concentrations (including pesticides, NH3 and BC) + climatic and topographyic data + forest cover data, for the period 2016-2020 per pixels.
