Hybridization is an important evolutionary pathway to genetic diversity, fitness, and ultimately to the emergence of new species. In contrast, hybridization between a native and an introduced species can lead to a loss of locally adapted gene complexes and ultimately to the extinction of the native. In the last decade, hybridization between native and introduced species has become a growing concern as non-native species are introduced far from their points of origin. The preservation of natural dunes along the shores of the Great Lakes is of particular concern because these habitats provide natural erosion control and support populations of locally rare taxa, including Great Lakes sea-rocket (Cakile edentula ssp. edentula var. lacustris).
