  1. Slope (°): Level (0), nearly level (0.3–1.1), very gentle (1.1–3), gentle (3–5), moderate (5–8.5), strong (8.5–16.5), very strong (16.5–24), extreme (24–35), steep (35–45), very steep (> 45). The ‘predicted suitability’ values for the occurrence localities have been extracted from the logistic output of Maxent. The occurrence localities have been grouped under various suitability classes based on the range of predicted suitability values as very high (0.8–1.0), high (0.6–0.8), medium (0.4–0.6), low (0.2–0.4), and very low (< 0.2)
