Western Michigan University Biological Sciences professor Tiffany Schriever says she and a group of students walk the trails down to wetlands from spring to fall. They use nets and water chemistry equipment to test the waters near the Great Lakes coastline. Schriever will be among the presenters at Western Michigan University’s Spring Convocation on Tuesday, March 26th at the Fetzer Center. She says they have found great diversity in wetlands, even those that are relatively close together.
