Shapiro normality test was completed in RStudio 1.4 for all variables with recognised blanket bogs studied at the European regional level (Table 5) before undertaking further statistical tests. Since all data was normally distributed, relationships between the recognised area of blanket bogs and the windfarm developments were tested using Pearson correlation test.

Normality test results of all variables studied at European regions NUTS level 2.
