Page  1 ï~~2010 THE MICHIGAN BOTANIST THE VASCULAR FLORA OF SEBERT PROPERTY, LAPORTE COUNTY, INDIANA Scott Namestnik Keith Board JFNew 616 South Washington Street 708 Roosevelt Road Bremen, Indiana 46506 Walkerton, Indiana 46574 ABSTRACT Sebert Property is comprised of an approximately 40-acre matrix of hummocky wet to mesic flatwoods, dry sandy upland flats with seasonally inundated depressions, mesophytic forests and a buttonbush pond. A remarkable assemblage of 362 taxa of native vascular plants occurs here. Twenty (20) species are listed as endangered, threatened, rare (ETR) or extirpated in Indiana; additional taxa are uncommon in the Chicago Region and Indiana and 13 species are presented as new records for LaPorte County. Keywords: Vascular Flora, Flatwoods, LaPorte County, Sebert Property INTRODUCTION Sebert Property is a 39.2-ac (15.8-ha) parcel that was donated to the LaPorte County Parks Foundation on 1 September 2000 by the late Wilmer and Rose Sebert, becoming the fifth county park in LaPorte County. No development has occurred at the site since that time. The property consists of swamp forest, early successional forest, mesophytic forest, upland forest, buttonbush swamp, sand barrens, seasonal pond, open water/mudflat, abandoned access road and roadside/roadside ditch communities. Portions of the property have been subjected to anthropogenic disturbances in the past, including excavation, likely for sand mining, and planting of pine trees; other portions are intact natural communities. A large percentage of the site consists of a community classified as boreal flatwoods by the Indiana Department of Natural Resources and The Nature Conservancy; Jacquart et al. (2002) describe the boreal flatwoods community as being dominated by Quercus palustris, Acer rubrum and Ulmus americana, with characteristic species including Betula papyrifera and Ilex verticillata. We performed a thorough inventory of the vascular flora of Sebert Property in 2007 and 2008 because there is a lack of published data on sites with boreal flatwoods and associated communities in northern Indiana. In addition, an earlier informal study showed that Sebert Property was comprised of a rich flora that includes endangered, threatened and rare (ETR) plant species, numerous plants of high conservation value and several plant species not previously known from LaPorte County.

Location Sebert Property is located approximately 6 mi northeast of Michigan City, Indiana, on the south side of County Road 925 North, 0.6 mi west of County Road 300 West, directly south of Wintergreen Woods Nature Preserve in northern LaPorte County. The property is 1.3 mi south of the Michigan state line in Springfield Township, in the southeast of the southwest of Section 16, Township 38 North, Range 3 West (44Â~44'N, 86046'W). Soils and Geology The property is located in the Oakville-Morocco-Brems soil unit; seven soil map units are present on the site (Figure 1) (USDA 1982). Moderately well drained to well drained fine sands (Brems fine sand; Oakville fine sand) are present in a low ridge that runs east-west across the site. Very poorly drained organic soils (Histosols and Aquolls) are present in a depression in the northwest corner of the site, and poorly to somewhat poorly drained soil (Saugatuck-Pipestone complex) exists along the north boundary of the site. The remainder of the property consists of fine sands and fine sandy loams that are somewhat to very poorly drained (Cheektowaga fine sandy loam; Morocco loamy fine sand; Newton loamy fine sand). Sand deposits at Sebert Property and in much of northwest Indiana are thought to be remnants of ancient beaches of glacial Lake Chicago, the precursor of Lake Michigan (Greenberg 2002). Natural Communities Located in the Northwestern Morainal Natural Region, Sebert Property is near the boundary between the Valparaiso Moraine Section, the Chicago Lake Plain Section and the Lake Michigan Border Section (Homoya et al. 1985). The

Page  3 ï~~2010 THE MICHIGAN BOTANIST Valparaiso Moraine Section is characterized by forest to the east and prairie to the west, as well as fen, bog, lake, marsh, savanna, seep spring and swamp communities, on generally well drained calcareous silty clay loam soils; the Chicago Lake Plain Section is characterized by marsh, lake, sand savanna, sand prairie, forest and swamp communities on mostly acidic sandy soils; the Lake Michigan Border Section is characterized by beach, dune, forest, savanna and panne communities on sand and muck soils (Homoya et al. 1985). The plant communities and soil chemistry at Sebert Property are most similar to the communities that characterize the Chicago Lake Plain Section to the west, as marsh, swamp and forest communities are present on sandy and mostly acidic soils (USDA 1982). Of the swamp community behind the dunes of Lake Michigan, Swink & Wilhelm (1994) state that "this system is one of the richest and most complicated systems in our region... characterized by a complex hydrology and... interspersed by gentle rises, shallow depressions, and hummocks.. " Sebert Property fits this description quite well. In addition, several degraded communities including old-field, sand blowout and young successional forest are present. Historically, the central early successional forest, central sand barrens and west sand barrens are presumed to have been a sand ridge. This area has been cleared of vegetation and leveled within the past 40 years. MATERIALS AND METHODS Floristic Inventory A meander survey following the methods of Goff et al. (1982) was conducted in 2005 by the authors with occasional assistance from others, resulting in a plant list of 292 taxa. For that study, collections were made for identification purposes but no attempt was made to collect voucher specimens for the entire flora. The resulting species list from 2005 was used as a guide for this more thorough study also conducted by meander survey in 2007 and 2008. The current study resulted in substantial additions to the list of known vascular plants at Sebert Property. Plant communities were generally mapped (Figure 2) as part of the study to document location of occurrence of collected specimens. With a few noted exceptions, a specimen of each taxon was collected and deposited at the herbarium of The Morton Arboretum, Lisle, Illinois (MOR).

Page  4 ï~~THE MICHIGAN BOTANIST Vol. 49 very small numbers, only photographic vouchers were submitted. The primary sources for plant identification were Gleason & Cronquist (1991) and Swink & Wilhelm (1994). Additional resources consulted for the identification of plant species included Deam (1940), Fernald (1950), Flora of North America Editorial Committee, eds. (1993+), Hitchcock (1950), Holmgren (1998), Mohlenbrock (2002), Steyermark (1963), Voss (1972, 1985, 1996) and Yatskievych (1999, 2006). Nomenclature in the species list follows The PLANTS Database (USDA, NRCS 2009). Floristic Quality Assessment Floristic Quality Assessment (FQA) was used to evaluate the natural area potential of the site and to allow for comparison with other sites where inventories have been conducted. Coefficient of conservatism values (C-values) for Indiana were obtained from Rothrock (2004). The methods outlined by Swink & Wilhelm (1994) and Rothrock (2004) for determining floristic quality were followed. RESULTS Floristic Inventory A total of 434 vascular plant taxa representing 245 genera and 90 families were observed and identified to at least the species level (Appendix 1). Of these, 362 (83%) are native to the Chicago Region; seventy-two (17%) are non-native. These figures consider the following species, which are native in Indiana but thought to be non-native in the Chicago Region or intentionally introduced at the site, as non-native: Andropogon virginicus, Pinus virginiana, Robinia pseudoacacia, Thuja occidentalis and Tridens flavus var. flavus. Many of the non-native plants occur in disturbed ground on the edge of County Road 925 North along the northern site boundary. Four additional taxa were observed but not identified to species: two species of Platanthera, one species of Typha and one species of Vernonia. Several individuals of one of the species of Platanthera (SAN PH-6 [MOR]) were observed, but none produced flowers during the study. One individual each of the other species of Platanthera (SAN PH-8 [MOR]), Vernonia (no collection) and Typha (no collection) were observed, but none of these produced flowers during the study. The Typha sp. was found along the right-of-way along County Road 925 North and was mowed prior to anthesis. These taxa were not included in the total species count or the Floristic Quality Assessment. Pteridophytes were represented by 22 taxa (5%), gymnosperms were represented by six taxa (1%) and angiosperms were represented by 406 taxa (94%). Poaceae was the most common family, with 51 taxa (12%) identified. Asteraceae and Cyperaceae were also well represented, with 44 taxa (10%) each. Rosaceae was the fourth most common family, with 25 taxa (6%) collected. Carex was the most well represented genus, with 35 taxa (8%) documented. Swink & Wilhelm (1994), in their discussion of Woodwardia areolata (L.) T. Moore, note that "the dune region is a virtual repository of both boreal and coastal-plain disjuncts and relicts." There are numerous plants at Sebert Property that are more commonly encountered outside of the Chicago Region, some of which may be remnants from a time when the climate was cooler, or from when coastal areas were further inland. The term "boreal" is certainly applied differently at every latitude. In Indiana and the Chicago region, this description is used

Similarly, coastal plain disjuncts, as referred to in Indiana and the Chicago region, are those plants that are much more common on the coastal plain and outer piedmont of the Mid-Atlantic states, but that are much more restricted in distribution in the Great Lakes states. Using categorizations from Swink & Wilhelm (1994), nine naturally occurring boreal relicts (Table 1) and 12 naturally occurring coastal plain disjuncts (Table 2) were observed. Examples of boreal relicts are shown in Figures 3-7 and a coastal plain disjunct is shown in Figure 8. Many other species characteristic of the boreal flatwoods community were documented. Floristic Quality Based on the taxa identified, Sebert Property has a mean C-value of 3.7 (native mean C-value of 4.4) and a floristic quality index (FQI) of 76.0 (native FQI of 83.3). Sites with mean C-values of 4.5 or higher or FQI values of 45 are usually representative of intact natural plant communities (Swink & Wilhelm 1994). As shown in Figure 9, the C-value distribution of native species generally follows a bell curve, with the greatest percentage of native species having a C-value of 4 (63 species, 17%). Species with a C-value of 4 occasionally thrive in communities with anthropogenic disturbance (Rothrock & Homoya 2005). Despite past disturbance at Sebert Property, 31 species (9%) have a C-value of 9 or 10 (Table 3). These plants are thought to be restricted to remnant landscapes that appear to have suffered very little post-settlement trauma (Rothrock 2004).

Plants on the endangered list have one to five occurrences statewide; those with six to 10 known occurrences are listed as threatened; rare species have 11 to 20 known occurrences. A fourth category of concern is watch list. Watch list species were previously on the ETR list but have since been removed, often because they are represented by greater than 20 occurrences. If a plant is removed from the ETR list, it remains on the watch list perpetually, unless there is reason to move it back to ETR. Watch list species are not actively tracked by the IDNR. (M.A. Homoya, pers. comm., February 2008) Table 4 displays a list of plants observed at Sebert Property that are considered endangered, threatened or rare in Indiana, or that are on the watch list (IDNR 2010). Seven species listed as endangered, three listed as threatened and nine listed as rare were observed on the site. Examples of some of these species can be seen in Figures 10-12. One species previously thought to be extirpated from Indiana, Lonicera canadensis (SAN 152 [MOR]), was observed at the site. Two orchid species that never produced flowers during the study were observed;

DISCUSSION Sebert Property consists of a mosaic of plant communities that are collectively considered boreal flatwoods (Figure 2). The most common tree species based on visual observations include Acer rubrum, Betula papyrifera, Fagus grandifolia, Liriodendron tulipifera, Nyssa sylvatica, Quercus alba, Q. bicolor, Q. palustris, Q. rubra, Salix nigra, Sassafras albidum and Ulmus americana. A mix of swamp forest (Figures 13 and 14), mesophytic forest (Figure 15) and upland forest (Figure 16) make up the north and south thirds of the property. These are the communities least disturbed by anthropogenic influences. Tree tip-ups are common throughout the swamp forests (Figure 17), creating functional microhabitats and amphibian breeding pools. Shrub swamp dominated by Cephalanthus occidentalis occupies the northwest corner of the site (Figure 18). Within this buttonbush swamp, a small submerged/emergent wetland that is seasonally to permanently inundated is present in the extreme northwest corner. A somewhat level area that was once a higher sand ridge runs approximately east-west through the middle of the property. As shown on the base map aerial photograph for the LaPorte County Soil Survey, ca. 1970 (Figure 1), this ridge was cleared of vegetation for farming, pasture or potential use as a sand borrow area. These sand flats now exist mostly as disturbed communities including young successional forest (Figure 19) and sand barrens (Figure 20), including a sand blowout area (Figure 21). Conifers in this area that presumably were planted include Pinus sylvestris, P. virginiana, and Thuja occidentalis. Two seasonal ponds that

Photograph by Keith Board. can be characterized as acid sand flat openings are present here (Figure 22). Many species in these flats are typically found in artificial excavations where sand has been removed down to the water table (Swink & Wilhelm 1994); it is likely that sand was removed from these areas in the past. Two excavated ditches are present on either side of an abandoned access road at the north end of the site (Figure 23). These ditches lead to the roadside ditch along County Road 925 North (Figure 24); it appears that an attempt was made at some point to drain portions of the property. Comparisons of floristic inventories should be viewed with circumspection, as many variables, including different surveyors, different methods of collecting and identifying species and different levels of survey intensity can all play a part in the number of species observed. With these things in mind, comparing the quality of natural areas in terms of number of species, mean C-values and FQI can generally show where a site ranks in terms of natural area floristic quality. With 434 vascular plants in 40 acres, Sebert Property has a level of species richness greater than that at other sites of equal or greater size for which vascular plant inventories have been recorded in Indiana (Appendix 2) (Rothrock & Homoya 2005; Angstmann et al. 2006; Ruch et al. 2008; Ruch et al. 2008). Of the sites shown in Appendix 2, Barker Woods Nature Preserve is most like Sebert Property in terms of plant communities and species composition. Barker Woods has a higher mean C-value than Sebert Property, but Sebert Property has more than twice the number of species, including natives, resulting in much higher FQI values.

Page  17 ï~~2010 THE MICHIGAN BOTANIST 17 2010 THE MICHIGAN BOTANIST 17 FIGURE 20. West sand barrens, April 5, 2008. Photograph by Scott Namestnik. The numerous plant communities at Sebert Property support a diverse mix of vascular plants, including several ETR species and species with affinities to more boreal or coastal plain regions. It is noteworthy that 83% of the 434 vascular plants documented in the flora of Sebert Property are considered native, and that 13 new county records were discovered. In addition, 31 of the recorded species have C-values of 9 or 10, indicating that portions of the site still harbor pre-settlement natural area quality despite moderate anthropogenic disturbance in the past. Sebert Property is an important tract of land for conservation of at-risk plant species in Indiana. The Lake Michigan-influenced climate, the acidic soils and the location of the site at the northern extent of Indiana allow species that are more common further north to survive here at the southern extent of their geographic ranges. Many of these boreal relicts are considered species of concern in Indiana because they are not known from other parts of the state. The presence of 10 native species not previously known from LaPorte County further illustrates the ecological significance of Sebert Property. The unique assemblage of plant communities, soil types, hydroperiod and disturbance provides appropriate conditions for species otherwise unknown from LaPorte County to survive at this location. This approximately 40-acre tract of land also provides habitat for Lonicera canadensis, a native shrub that was considered extirpated from Indiana prior to this study. Future research at Sebert Property and in northern LaPorte County in general could be directed towards the genera Dichanthelium at drier sites and Betula in forests. A population of an unusual Dichanthelium, determined as D. oligosanthes (SAN 474 [MOR]), was collected in early successional sand barrens at the site. The

Page  20 ï~~20 THE MICHIGAN BOTANIST Vol. 49 plants have long spreading papillose-based upper sheath hairs and purplish culms, and are intermediate between D. oligosanthes ssp. oligosanthes and D. oligosanthes ssp. scribnerianum. Though the plants have longer, narrower leaves characteristic of D. oligosanthes ssp. oligosanthes, they have shorter spikelets characteristic of D. oligosanthes ssp. scribnerianum. Another Dichanthelium of interest, tentatively determined as D. clandestinum x depauperatum (Board 652 [MOR]), was discovered in early successional sand barrens near a sand blowout. Trees of the genus Betula are frequent in northern LaPorte County, and both B. papyrifera and B. populifolia are encountered at Sebert Property. It would be important to determine whether the two are hybridizing, as trees with intermediate characteristics are observed frequently. It is also unclear whether local colonies of B. populifolia are naturally occurring or escaped from cultivation. Perhaps most importantly, many local reports of B. populifolia are misidentifications of B. pendula (European White Birch), which often grows in sandy woods in the dune area, and telling these two species apart can be "quite a trial" (Swink & Wilhelm 1994); this has important implications for management purposes. This study provides a baseline to help future researchers understand the natural and anthropogenic changes occurring at Sebert Property and the surrounding area. Ideally, our study will promote further botanical studies as well as a casual appreciation of the local flora. In addition, it will provide useful data for the owner, LaPorte County Parks Foundation, as management and/or development decisions are considered. To preserve the natural character of the property, it will be increasingly important to monitor the spread of invasive species, which can quickly lead to the degradation of a natural area. This will be especially important along anthropogenically disturbed areas such as the road and trails through the site. Natural succession will also cause changes to the flora of the site. The plant communities present at Sebert Property will require some form of disturbance to be maintained in their present state. In swamp forest areas, windthrown trees naturally open the canopy and reset successional processes. In the acid sand flat openings, historic sand mining removed accumulations of organic material and exposed an ancient seed bank; without disturbance these areas are expected to fill in over time, changing the composition of the acid sand flat openings flora. The successional forest and sand barren communities will also change with time if no management takes place. Future management decisions will determine how the flora of Sebert Property changes in the coming decades.
