Ehrle Department of Biological Sciences Western Michigan University Kalamazoo, MI 49008 woodyehrle5098@sbcglobal.net During the summer of 2004, I made seven visits to the Kalamazoo Nature Center's 1100 acre tract at 7000 N. Westnedge Ave., approximately 5 miles north of Kalamazoo, Michigan. The visits lasted about three hours each. Six visits were made to different parts of the tract to collect moss and liverwort specimens. The seventh visit was made to place labels for the seven most common liverworts and mosses along trails in the hope that a guide sheet could be prepared and given to visitors interested in learning about these plants. Mr. Tyler Bassett of the KNC research staff accompanied all my visits to insure that areas collected were properly identified. He also independently collected a number of specimens for inclusion in this report. This study was conducted as part of the KNC Bioinventory project and was supported by a grant from the Hanes Fund. The six collecting trips, areas visited, and the number of collections made are presented below in Table 1. Microscopic examination of the 127 collections resulted in 152 moss and liverwort identifications, representing 55 different species. In some collections several species were growing intertwined. The 55 species identified probably represent 90+% of all moss and liverwort species growing on the KNC property. A recent 3-year study in Cass County of a 1400-acre tract resulted in 277 collections, representing 59 different species of mosses and liverworts, including seven species of Sphagnum. Only one species of Sphagnum was collected on the KNC tract, due to the fact that there are no bogs on the property. To get beyond the 90+% level would require more collecting trips, particularly into areas of the KNC not visited in the present study. TABLE 1.

Information on the 55 species of mosses and liverworts is presented in two different lists. The first is an annotated list of the species arranged in alphabetical order along with descriptions of the microenvironments in which each is found, the number of times each was collected, and estimates of its frequency on the property. Each listing begins with the scientific or technical name of the moss or liverwort. This consists of the genus and species to which it belongs and the name(s) of the person(s) who created the currently accepted binomial. This is followed by the common name of the plant for those mosses and liverworts having common names. Many of the common names follow those of Glime (1993). The number in parentheses indicates the number of times it was identified in the collections. This is followed by an estimate of its frequency on the KNC property and the type of microenvironment in which it occurs. Each listing ends with the areas of the KNC in which the species was found. The areas listed are those on the compartment map of the KNC property provided by the KNC research staff (Fig. 1 & Table 2). The second is a taxonomic list which presents the 55 species arranged by class, order, and family. All nomenclature and the sequence of families and orders is based on Crum (1983) and Crum (1991); the author citations are those adopted by W3MOST at www.mobot.org. A set of collections representing all 55 species is being prepared for the KNC. Except for

These are entirely typical of the bryoflora of southwest Michigan. Comparison with studies of similar tracts suggests that the 55 species represent 90+% of all moss and liverwort species on the KNC property. The number of species present is held down by the lack of bogs, rock outcroppings, and water-falls on the KNC property. These are habitats in which many moss and liverwort species thrive. The richest environments on the KNC property for mosses and liverworts are the mature forests along the Cooper Glen Trail, the bed and borders of Trout Run, the edges of the Source Pond and the flood plain of the Kalamazoo River. The single richest microenvironment is rotting logs, particularly when they have become decorticated. No rare or endangered bryophyte species were encountered during this study. In fact, most of the species found at the KNC are quite widespread. Some of them are circumboreal in distribution and represent remnants of the great Tertiary age forests that once clothed the northern hemisphere of the planet. There is an amazing similarity in the bryoflora of southern Michigan from place to place. Thus, one can be quite confident that one will find Fissidens, Thuidium, Mnium, Lopohocolea and a number of other genera each time you step into a Southwest Michigan woodlot. To be sure, there are differences from place to place as well. This is the result of the fact that some of the species are quite widespread but don't occur everywhere. Plants like Porella, Climacium, Nowellia, and Pallavacinia are always a surprise wherever they are found.
