Fig 5 — The projected climate suitability for V. germanica in Australia, (a) without irrigation, (b) with 2.5 mm day^-1 top-up irrigation during summer and (c) with a composite risk irrigation scenario (where areas are not under irrigation, the EI of the natural rainfall scenario is mapped, while with areas under irrigation the EI of the irrigation scenario is mapped), using the CLIMEX Ecoclimatic Index (EI). Open circles: presence sites; black crosses: absence sites (distribution data for Tasmania is not shown); blue dotted lines: main rivers. Unsuitable: EI = 0; marginal: EI = 1–4; suitable: EI = 5–9; highly suitable: EI = 10–29; optimal: EI = 30–100.
