The Red Lake peatland in Minnesota has a diverse range of mosses and liverworts, with different types of vegetation like bogs and fens. The peat-forming mosses in this area are mainly Sphagnum species in bogs and Amblystegiaceae family on minerotrophic sites. These mosses play a crucial role in forming peat, which is important for the environment. The researchers found that the major peat-forming moss species are common and have specific habitat requirements, but these requirements can vary in different parts of the northern hemisphere. This study helps us understand how different types of mosses contribute to the formation of peat in wetland ecosystems like Red Lake peatland.
