Vegetation plots in 4 Great Lakes coastal national lakeshores were surveyed during 1998-1999 to measure abundance and distribution of non-indigenous plants. The number of plots sampled in each lakeshore varied: 618 at Indiana Dunes National Lakeshore, IN; 834 at Pictured Rocks National Lakeshore, MI; 927 at Sleeping Bear Dunes National Lakeshore, MI; and 1431 at Apostle Islands National Lakeshore, WI. All plants within the plots were identified, whether native or non-native, and their relative abundances and locations were recorded. Frequency of non-indigenous species by plot and by random transect are reported for 3 of the lakeshores and frequency by plot and by island for Apostle Islands National Lakeshore. Vectors and patterns of invasion and establishment are categorized. Seven significant, non-native species are discussed individually: spotted knapweed (Centaurea maculosa), baby's breath (Gypsophila paniculata), purple loosestrife (Lythrum salicaria), white sweet clover (Melilotus alba), garlic mustard (Allaria petiolata), dame's rocket (Hesperis matronalis), and multiflora rose (Rosa multiflora).
