"Figure B1. Predicted climatic suitability A. philoxeroides in Durban. The model is highly accurate in predicting climatic suitability (0.929 ± 0.007 – AUC±SD). Predicted suitability is indicated using a colour scale (darker shades indicate higher predicted suitability). Also indicated are the potential points of introduction and potential points of first naturalisation to monitor for A. philoxeroides in Durban. Pathways of introduction: Ship ballast (historical), transportation of habitat material, ornamental purposes Potential points of first introduction: The Durban harbour, plant nurseries and garden centres, pet and aquarium shops Habitat and Land uses: Alternanthera philoxeroides can grow in a variety of habitats but is usually found in aquatic habitats, particularly rivers, lakes, dams, ponds, canals, flood plains and irrigation channels Habitats present in Durban: Yes Potential sites of first naturalisation in Durban: The Durban harbour and adjacent river systems (particularly uMhlatuzana and uMbilo river systems)"
