Description: Number of harmful species that have invaded marine habitats, by marine ecoregion. The occurrence and ecological impact of marine invasive species were compiled in a geographically referenced database by Molnar et al. (2008). Information about 329 species was systematically collected from a wide variety of global, regional, national, and subnational data sources. Non-native distributions were documented by marine ecoregion. The threat of each species to native biodiversity was scored using the following categories: 4, disrupts entire ecosystem processes with wider abiotic influences; 3, disrupts multiple species, some wider ecosystem function, and/or keystone species or species of high conservation value (e.g., threatened species); 2, disrupts single species with little or no wider ecosystem impact; 1, little or no disruption. Species in the top two categories (scores of 3 or 4) are considered “harmful invasive species” in this atlas (n=187), and the number of these are displayed in the map by ecoregion. These data were derived by The Nature Conservancy, and were displayed in a map published in The Atlas of Global Conservation (Hoekstra et al., University of California Press, 2010).
