“The two great destroyers of biodiversity are, first habitat destruction and, second, invasion by exotic species.” –E.O. Wilson
The spread of invasive species is a major factor contributing to ecosystem change and instability, ultimately leading to biodiversity reduction. Preventing non-native invasive species establishment has a much better success rate than trying to eliminate a species once it is established. At Apostle Islands NL, both aquatic and terrestrial species continually threaten the park. From microscopic organisms to large trees, the potential is always there for non-native species to invade and overtake fragile ecosystems that make the lakeshore a popular destination for hikers, boaters, and sightseers alike.
