Community composition of terrestrial plants provided by the DNA analyses from Lake Muzelle. The richness (mean and maximum), the percentage of arboreal taxa and several taxa (species and genus) of different ecological preferences (mentioned on the right side of the figure) were selected to document the landscape and environmental changes. Alchemilla sp. and Potentilla sp. can have different ecological preferences according to the species. However, these pollen types were frequently observed in overgrazed and trampling sites⁹². A study on lake sediments DNA also observed these taxa during phases when pastoral activities with sheep and/or cow were recognised²⁵. For each taxon, the size of circles is proportional to the number of reads (see scale on the top of the figure).
