Optimal transformation of species cover for vegetation classification

, 2020
Aims: Vegetation-plot sampling usually involves estimating species cover. For classifying plots to vegetation types, covers are often transformed to decrease the effect of dominant species. However, it remains unclear which transformation is optimal.
