Composition and Productivity of Bryophyte Assemblages in Natural and Restored Wetlands.
The prairie pothole region is an economically and ecologically important swath of over 300,000 miles of glacially-created wetlands dotted across a nutrient-rich landscape. These wetlands occur in alkaline soil, lack Sphagnum, and are classified as shallow or deep marshes, wet mesic prairie, or shallow open-water communities. There is a dearth of information available on the occurrence and ecology of bryophytes in these wetlands. We surveyed bryophytes in 32 shallow water marshes that ranged in age from recently restored to natural (never tilled). Bryophyte species richness in these wetlands was relatively low; the dominant species was Leptodictyum riparium, which was found at all sites. Natural marshes had higher species richness than restored marshes and Drepanocladus aduncus was more likely to occur in natural than restored wetlands and some species occurred only in natural wetlands. Bryophytes were most often found under a canopy of cattails and total bryophyte biomass was significantly positively related to area of cattails at a marsh site. Productivity at natural wetlands was comparable to that reported for Sphagnum-dominated forest bogs.
