Figure 5 in Improving kettle holes as habitat and reproduction areas for amphibians - a case study in organic farms in north-eastern Germany

Figure 5. Influence of the clearance of woody plants on the number of kettle holes with species occurrence (a) and species with reproduction (b) in organically farmed fields in north-eastern Germany. 6 pairs of kettle holes are shown each with a maximum of 7 species (2018-2020). Each point represents a pair of kettle holes. The diagonal line describes no difference in species numbers, and points above show an incidence of more species after the removal.
