Fish and Wildlife Service, over a third of American adults are birders. They may want to have Erie Marsh Preserve on their radar, as it's a haven for all manner of birds. Need to check great blue herons off your birder list? If you're more into botany than birds, Erie Marsh Preserve is one of the few places in Michigan you can still find the American lotus and swamp rose-mallow. Look for the rich yellow of the stunning lotus and the reds, pinks, and purples of the rose-mallow near the shoreline, perhaps while walking on one of its trails.
