Figure 3. A distribution model created from the naturalised range of Chenopodium vulvaria outside Europe and extrapolated back to Europe.

A distribution model of Chenopodium vulvaria in Europe, North Africa and the Middle-east projected from its naturalised range in California, South America and Australia. This model aims to predict where, according to the naturalised range, the climate is suitable for persistent populations in Europe as opposed to casual occurrences. The map uses a Mollweide equal area projection.
