Populations of rare and exotic plants were mapped at Indiana Dunes and Sleeping Bear Dunes National Lakeshores during the summer of 2003. The analysis of associated species demonstrated the habitat specificity for most species. The data indicated the presence of human trampling and animal browsing in the populations of some species (showy orchids) that may be a concern for the viability of the species.
