Apostle Islands flora

Symposium Banner

Situated at the transition from northern hardwoods to sub-boreal forest, the Apostle Islands National Lakeshore’s vegetation is a signature of both broad-scale physiographic processes and localized coastal and maritime influences.

A variety of human uses and stewardship is also key to the natural history and vegetation patterns in the park. Diverse physical landforms and a variety of habitats contribute to the high total plant diversity of 810+ species documented within the Lakeshore.

In this talk, I will provide a virtual tour of the predominant or unique plant communities and species in the park, and I’ll share insights about some of the changes that have occurred, as well as stories of resilience.
