Partial Pearson’s correlation tests on factors might affect the water point visits of the two targeted equid species.

The degree of association (correlation coefficient) between two variables was tested after removing the effects of other variables. Significant P values were marked with asterisks. aPearson’s Correlation Coefficient bStrength of Correlation: <0.1 zero correlation; 0.1–0.3 weak correlation; 0.4–0.6 moderate correlation; 0.7–0.9 strong correlation; >0.9 perfect correlation cSignificance level after Bonferroni correction: ‘***’ <0.0001. Partial Pearson’s correlation tests on factors might affect the water point visits of the two targeted equid species.
