Scheme representing the number of papers including highly invasive acacias considered: Acacia dealbata, A. longifolia, A. mearnsii, A. saligna and A. melanoxylon, through different areas across the world. Map is created based on information (n = 214 manuscripts) after the search in SCOPUS by using the key terms Acacia and plant and invas* (TITLE-ABS-KEY)+ and “Acacia dealbata” or “Acacia longifolia” or “Acacia saligna” or “Acacia melanoxylon” or “Acacia mearnsii”. Systematical reviews on the Acacia invasive process were not included unless they were strictly focused on a specific area. Note the different scale for the last interval (1999–1980)
