Evolution in a Glaciated Landscape: Contribution of Endemism to Great Lakes Biodiversity

Penskar, Michael R. [1].

Conservation Status of Rare Endemic Species and Habitats.

Rare endemic plant species of the Great Lakes comprise a relatively small proportion of the regionís flora yet play an important role in many natural communities critical to the functioning of the Great Lakes environment. Many of these endemics, including allied animal species, have been shown to be indicators of ecosystem condition and health. The regionís endemic rarities have also long been the focus of studies by plant geographers and other researchers interested in the processes of colonization, succession, and evolution occurring over the areaís complex glaciated landscapes. Here I provide an overview of the conservation status of the regionís rare endemics, including summaries of known distributions, monitoring and management efforts, ongoing conservation activities, and selected research efforts by Michigan Natural Features Inventory and collaborators. Also provided is an analysis of the threats to the habitats and ecological processes necessary to sustaining and perpetuating Great Lakes endemic plants. I conclude with an evaluation of how federal recovery plans and other management, stewardship, and research efforts have fared over the last one to two decades in helping to achieve the protection of these species and their ecosystems.
