Other important collectors or students of Wisconsin Bryophytes include C. Barnes (WIS), F. Bowers (UWSP), L. Cheney (WIS), G. Conklin (WIS), J. Christy (MPM), R. Evans (WIS), S. Freckmann (UWSP), H. Iltis (WIS), R. Koch (UWL), and M. Nee (WIS). As seen in chart below, the peak activity in bryophyte collecting was between 1960-1980 with over 10,000 collections in that time frame. 5000 3000 Collections 1000 0 1800 1840 1880 1920 1960 2000 year Atlas Methodology Records were downloaded from the Consortium of North American Bryophyte Herbaria website and supplemented by the database at the Milwaukee Public Museum (MPM). Currently, 41,456 Wisconsin collections are databased. Names were then examined to check for synonymy, remove unidentified specimens, and remove specimens lacking locality data. When possible, dubious specimens at WIS have been checked. However, specimens from other herbaria have not been checked unless they are present in duplicate at WIS. In cases where the identifications are highly dubious, these collections have not been mapped and thespecies excluded from the flora for the time being. 3 Mosses Floristics Mosses (Bryophyta) can be found in all terrestrial and aquatic habitats throughout Wisconsin. Habitats particularly well-suited for large amounts of moss diversity include cliff faces, wetlands (bogs, fens) and particularly white cedar (Thuja occidentalis) swamps. The distribution and diversity of mosses is far from uniform throughout the states (see map). This is due to a combination of non-uniform distribution of habitats and collection bias towards more “scenic” areas. The problem of collection bias is further hampered by a lack of bryologists actively collecting in Wisconsin in the last several decades. Areas of the highest moss diversity in the state are (1) the Driftless Area, particularly the Baraboo Hills, (2) the Wisconsin River Drainage, (3) the Lake Superior shore, and (4) the Door Peninsula. Conversely, areas of low diversity are (1) West-Central Wisconsin and (2) the Lake Winnebago Area. High diversity areas (1), (2), and (4) are also well-known for their high diversity of vascular plant species. The Baraboo Hills contains species that likely persisted in the Driftless Area during Pleistocene glaciation, but also contains some northern species disjunct from the northern part of the state. Driftless area specialties include Bryoxiphium norvegicum, Dicranodontium denudatum and Jaffueliobryum spp. Another floristically important feature of the Driftless Area is several Ozarkian species that enter the state in Grant County including Forsstroemia trichomitria and Zygodon viridissimus. Associated with the diversity of the Driftless area is a noticeable increase in diversity along the Wisconsin River (and apparent slight decrease in the Adams/Juneau County areas of glacial Lake Wisconsin). This seems to be sometimes associated with species that are more widespread in the northern portion of the state but follow the length of the river to the Mississippi River. Examples of this pattern include Homalia trichomanoides, Isopterygiopsis muelleriana, Mnium lycopodioides, and Saelania glaucescens. Door County is significant in its mixture of northern and southern habitats, but also supports several Great Lakes dune species such as Niphotrichum cansecens. Areas of low diversity are misleading in that the exceptionally low numbers are more than likely due to under collection (for example, Pepin County likely has at least one moss species), although habitat loss due to agriculture and/or relative habitat uniformity is likely to be an additional factor. These areas should specifically be targeted for additional records, especially the west-central part of the state, where speciesof a slightly more western distribution may yet be found. About the Maps & Nomenclature The moss flora of Wisconsin presently contains 412 species in 45 families. Nomenclature follows Floraof North America volumes 27 and 28. Grey shading in counties indicates one or more specimens documenting that species, although the identity of the specimen may not be verified. 4 Abietinella abietina Acaulon muticum Amblyodon dealbatus (Hedw.)
