Field Guide to Wisconsin Sedges: An Introduction to the Genus Carex (Cyperaceae)

Appendix B: Atlas of the Wisconsin Carex Flora

Appendix B Atlas of the Wisconsin Carex Flora MEREL R. BLACK AND THEODORE S. COCHRANE The Wisconsin distribution of each Carex species, subspecies, or variety is shown by a map. These maps are a joint product of the Wisconsin Botanical Information System database, created and maintained at the University of Wisconsin–Madison Herbarium (WIS), of the University of Wisconsin– Madison, and handmade maps produced over a period of 30 years by Theodore S. Cochrane. Both the database maps and the Cochrane Xoristic atlas maps have their roots in the work of Norman C. Fassett, Hugh H. Iltis, and their colleagues, who authored the Preliminary Reports on the Flora of Wisconsin series and books on Wisconsin ferns, grasses, and legumes. These works are based only on specimens examined, and all of them include a map for each species, showing its known distribution by dots, circles, or triangles and implying its relative frequency by the number of symbols. Throughout the preparation of these Carex maps, the specimen-based and exact-locality principles have been followed. The names on the maps reXect the same recent taxonomic revisions and nomenclatural decisions that appear in Flora of North America, vol. 23, and the Wisconsin Vascular Plants website (www .botany.wisc.edu/wisXora), except in three cases in which it proved difWcult to recognize taxa at the level of subspecies. The arrangement of taxa follows the numbering system used throughout this book. In 1974 Cochrane launched a long-term effort to gather sedge data from as many Wisconsin herbaria as possible and from several out-of-state and private collections as well. Using the U.S. System of Rectangular Surveys (townships /sections grid system) to plot location data, he manually placed colored pencil dots representing about 21,000 specimens belonging to twenty-seven institutional and two private herbaria onto blank working maps, mapping only specimens that had been annotated by James H. Zimmerman or himself or occasionally another authority on the genus. The many specimen labels that do not include such information were mapped to the nearest named place. The computer-generated maps were produced from the same 221 222 APPENDIX B survey data and/or place information. Employing the Landnet Wle from the GEODISC2.1 produced by the Wisconsin Department of Natural Resources, Geographic Services Section, the x,y coordinate was determined, then plotted by ArcView graphic information system software. A comparison of the computer-generated maps with the unpublished Xoristic atlas maps revealed that many collections that had been mapped manually were yet to be databased . Therefore, the database maps that are the basis of this appendix have been updated through the addition of county records copied from the manuscript maps. The databasing of the Wisconsin vascular Xora has occupied the attention of the staff of the Wisconsin State Herbarium since 1994. Grants from the Wisconsin Department of Natural Resources and National Science Foundation and funds from the Department of Botany and O. N. and E. K. Allen Herbarium Fund, of the University of Wisconsin–Madison, have enabled us to enter label data from WIS, a task nearing completion for all Wisconsin vascular plants in the holdings. For the privilege of incorporating records from collections that have already been databased we extend our most sincere thanks to the staffs of the Milwaukee Public Museum, the Morton Arboretum, and the University of Wisconsin–Green Bay.
