Figure 4

The projected global climate suitability for EBR under climate change scenario RCP 8.5, (a) the middle of 21st century (2046–2065), (b) the end of 21st century (2081–2100). Slash indicate the distribution countries of tree-of-heaven. Yellow indicates areas of marginal suitability (0 < EI ≤ 10); Orange indicates areas of moderate suitability (10 < EI ≤ 20); Red indicates areas of optimal suitability (EI ≥ 20).
