Figure 1. Climate suitability analysis results based on publicly available records of Japanese knotweed (R. japonica ) from Europe in the GBIF database as estimated in MaxEnt. Orange circles represent the localities of samples used to construct the climate envelope. Stars represent the source localities of each of the strains of A. itadori released, or under review for knotweed biological control.
