![This map indicates relative risk from ecoregions outside the northeastern United States, evenly weighting ballast water volume sourced from a region and number of ships from that region. Red represents the highest risk and yellow the lowest risk. Ecoregions in white did not source any ships with a destination in the northeast United States [Sources: Basemap: NOAA 2011; Ecoregions: Spalding 2007].](/sites/default/files/styles/term_page__news_article/public/images/201108/20110818153919-1.jpg?itok=7J1GI4Dz)
