Vegetation and nutrient status of northern Michigan fens
The vegetation, selected characteristics of shallow groundwater, and depth to water were examined in five fens in northern Lower Michigan. The field layer was the dominant stratum in all five fens and contained a total of 85 vascular species with a mean density of 30 vascular species per stand. Care...

The vegetation, selected characteristics of shallow groundwater, and depth to water were examined in five fens in northern Lower Michigan. The field layer was the dominant stratum in all five fens and contained a total of 85 vascular species with a mean density of 30 vascular species per stand. Carex lasiocarpa was the most prevalent dominant plant and attained a frequency–presence index (FPI) of 8000 of a possible 10 000 and a mean importance value of 33 of a possible 200. Other common dominants in decreasing order of FPI were Carex aquatilis (6640), Myrica gale (4636), and Andromeda glaucophylla (2000).
