Page  361 ï~~2004 THE MICHIGAN BOTANIST 361 A CHECKLIST OF THE VASCULAR FLORA OF WOODLAND DUNES NATURE CENTER, MANITOWOCTWO RIVERS, WISCONSIN. Charles R. Hart Department of Biological Sciences University of Wisconsin-Manitowoc Manitowoc, Wi 54220 ABSTRACT A floristic survey of the vascular plants of Woodland Dunes Nature Center was conducted over a period of approximately twenty years. I found 336 species, belonging to 300 genera and 70 families, in the area, which encompasses 1200 acres. INTRODUCTION A local flora is important to recognize and document for several reasons. It can serve as a baseline for comparisons to other local, regional and state floras today as well as into the future. It also provides information about various species presence and absence. In fact, in the course of this study, many new county records were established. Finally, these records will currently add to a major project underway to list the flora of Wisconsin (Checklist of the Vascular Plants of Wisconsin, 2001). This study was concentrated in an area that has changed in many respects over the years. The initial holdings associated with the area were quite minimal and over time have grown considerably; i.e., 40 acres in 1974 to 1200 acres in 2004 (Woodland Dunes Web site: History). Land areas that were initially purchased and that had been used for agrarian or residential purposes are undergoing succession. This study then is in no way complete, as floras are always in a constant state of flux. LOCATION AND LAND USE Woodland Dunes Nature Center is located in Manitowoc County between the cities of Manitowoc and Two Rivers (Fig. 1). The current acreage associated with the Center amounts to approximately 1200 acres. The map, Fig. 1, shows the boundaries and areas associated with the Center. The Center and its natural areas are in the West Two Rivers Township of Manitowoc County, T19-20N and R24E and R25E. The sections in the township where collections were made are numbers 35, 3, 2, and 10. Agriculture was the main contemporary land use in the area and subsequently residential as well as commercial development has taken place.

Page  363 ï~~2004 THE MICHIGAN BOTANIST 363 The Center came into being in 1965 as an outgrowth of various avian and educational studies by local educators/naturalists. In 1974, a committee was established with the goal to preserve approximately 1,200 acres for habitat and educational purposes. Today the Center provides educational programs, a trail system, and outdoor opportunities for the public. GEOLOGICAL AND PHYSIOGRAPHICAL FEATURES Cambrian formations of Paleozoic age underlie the study area sampled (Ostrom, 1981). Above the Cambrian formations are five approximately parallel units of sedimentary rocks of Ordovician, Silurian, and Devonian age. From east to west the eroded edges of these rocks appear in the following order: St. Peter sandstone; Sinnipee dolomite, with some limestone and shale; Maquoketa shale and dolomite; dolomite; and dolomite as well as shale. Like most of Wisconsin, the Woodland Dunes area was affected by glaciations. Various glacial lake forces had a more significant impact on the area than did the inland glacial stages. The glacial lakes that influenced the area started with the glacial Lake Algonquin, followed by Lake Chippewa, and finally Lake Nippissing. The last had the most significant impact on the Woodland Dunes Area. During this last glacial lake episode, the lake level was approximately 596 feet above mean sea level which is referred to as the Algoma level (Steffen, 1979). The present area associated with the dunes was once more completely inundated. Later in time, the lake level dropped to its present level of 580 feet above mean sea level. Within this time frame, the lake forces along with the lake level recession formed the beach ridges and swales. These formations at Woodland Dunes differ from other nearby areas along the lake. In most nearby areas, remnant ridges and swales, reflecting the higher lake levels, run parallel to the current shoreline. By contrast, the Woodland Dunes ridges and swales are fan shaped. The base or pivot point of the fan shaped ridges begins in the southeast corner of West Two Rivers township section 10, and then fans out to the northeast into sections 3, 2, and 35 (see Fig. 1). These fan shaped ridges and swales are thought to have developed as a result of an embayment that covered the present day Woodland Dunes area (Steffen, 1979). As the water level receded, the southeastern end of the embayment served as a major deposition point for the ridge/dune forming beach sand; while at the same time, beach sand deposits to the northeast were laid down in much smaller amounts. Consequently, the ridges and swales were formed in an unequal manner, wider or farther apart at the north end, and shorter or closer together at the south end (see Fig. 2). SOILS Woodland Dunes Nature Center is in an area dominated by soils that are underlain by outwash deposits. The soils are referred to as the Granby-Oakville

Page  364 ï~~364 THE MICHIGAN BOTANIST Vol. 43 364 THE MICHIGAN BOTANIST Vol. 43 FIGURE 2. Fan-shaped ridges and swals associated with Woodland Dunes. Tedrow unit. This unit is further described as consisting of soils on outwash plains that are physically interrupted by drainage outlets, old remnants of beaches and glacial lake beds (Soil Survey of Calumet and Manitowoc Counties, 1975). The Granby is the dominant soil type in the area. It is described as follows: topsoil: ca. 10 inches of fine, black sandy loam; and subsoil: ca. 26 inches of an upper brown, loamy fine sand followed directly below by a light yellowish brown sand. In the western part of section 10 of W Two Rivers Township there are Keowns soils as well as Shiocton soil types which are both essentially sandy loams. Interspersed with the Granby throughout all sections, and as well to the east in section 35, are the Tedrow loamy fine sands. To the north in section 35 one encounters Houghton muck along the West Twin River boundary of the Center (Fig. 1). CLIMATE The climate associated with the Woodland Dunes Nature Center is described as a modified continental climate (Otter, 1975). The reason for the designation as a modified continental climate is its proximity to Lake Michigan. The lake's influence is felt most strongly in the spring, summer, and fall. The mean average temperature for the area (thirty year data for Manitowoc, WI from, November 2003) is approximately 43.30 F or 6.3' C. The monthly mean average temperatures run from 19Â~ F or -7Â~ C in January to 70Â~ F or 21Â~ C in July. The average date for the last spring freeze is 17 May and the first fall freeze is around 2 October. The growing season averages around 138 days. Mean annual precipitation, including snowfall, is 30.48 inches. The prevailing wind is from the west, northwest, and southwest with average speeds of 13 miles per hour in April and November.

Page  365 ï~~2004 THE MICHIGAN BOTANIST 365 VEGETATIONAL COMMUNITIES AND HABITAT TYPES The location of Woodland Dunes Nature Center with respect to Lake Michigan and the "tension zone" results in an interesting mix of plant communities as well as habitats. As indicated above and in general terms, the climate associated with Woodland Dunes is cooler, wetter, and results in a shorter growing season than points inland. The floristic tension zone as described by Curtis (1959) separates the flora of Wisconsin into two major plant associations, northern and southern. Part of this tension zone running directly north to south from Green Bay to Milwaukee passes to the west of Woodland Dunes. The proximity of the Center to the tension zone is revealed by a mixture of northern and southern species common to Wisconsin major plant associations, the northern hardwoods and the southern prairie-forest. The classification of the vegetation communities at Woodland Dunes according to Curtis (1959) is mesic northern hardwoods and the wet-mesic southern hardwoods. In a recent study by Kotar & Burger (1996), plant associations were developed for smaller geographic areas in Wisconsin that more closely approximate the plant composition of actual communities. Based on this study, one major plant community comprises the flora of the Woodland Dunes Nature center. It is termed the beech-sugar maple forest with yellow birch and elms, as well as some hemlock and white pine along the Lake Michigan shoreline. These trees represent the common forest canopy or cover types and may also include black cherry. One noticeable omission from the study is its failure to mention or account for the presence of white cedar or black and green ashes which are very common in the swales or wet areas at the Dunes. The understory associated with the Dunes does match to some degree the shrubs and small trees recognized as being part of this community by the above study, those in part being: elderberry, choke cherry, and gooseberries. Further, the wet areas of the dunes are occupied by alders which are not mentioned by the above authors. The ground flora is also similar and as noted reflects the transition between the northern and southern floras of the state. Several southern species of note that are present are enchanter's nightshade, wild geranium, and mayapple. Northern flora types such as partridgeberry, wild lily-of-the valley, and big-leaf aster are typical inhabitants of Woodland Dunes Taxonomy, Nomenclature and Organization of the Checklist. Taxonomically, as well as in regard to nomenclatural considerations, this checklist adopts and follows the procedures outlined by Wetter et al. (2001) in the Checklist of Vascular Plants of Wisconsin. The references, resources, manuals, and electronic sources used were mostly identical to those used by Wetter et al.; e.g., Gleason and Cronquist's Manual of Vascular Plants 2nd. ed., 1991; Holmgren's Illustrated Companion to Gleason and Cronquist's Manual, 1998; and Flora of North America, three volumes, (1973, 1997, 2000). A valuable electronic resource that provided considerable information was the UW Wisconsin Herbarium ( site. The structure of the Woodland Dunes Nature Center checklist also mirrors or follows, with some ex

In cases where a particular taxon is, according to all resources, a new report for Manitowoc County, this is indicated. The collections for the flora are presently housed at the UW Manitowoc campus and duplicate specimens will be donated to the Woodland Dunes Nature Center.
