The Herbaceous Vascular Plants of Blackacre Preserve a Preliminary List II Additions for 2011 Season The Herbaceous Vascular Plants of Blackacre Preserve A Preliminary List II Additions for 2011 Season December 8, 2011 Submitted to: Kentucky State Nature Preserves Commission Submitted by: William E. Thomas Herbarium Indiana University Southeast Photo: Purple Rocket by Richard Lyons 1 Scope The goal of this survey was to compile a rough list of herbaceous vascular plant species on the below described tract. The survey was conducted from July 11, 2010 through the end of the growing season in 2011. This report is the second of the survey and augments the first report of December 2010 by adding many of the spring ephemerals which were missed due to the late start in the 2010 season. Any extensive populations of invasive alien species were noted as well. Locale Description The Blackacre Preserve website states that the property consists of 170 acres in eastern Jefferson County Kentucky. It is the authors understanding that some additional acreage (size?) was appended to the southern border of the original 170 acre tract. The property is located at 3200 Tucker Station Rd. The tract is bordered on all sides by housing and urban areas; a railroad track runs along the north border. The terrain is of mostly gentle slopes with some wooded areas and open fields formerly used for pasture or crops. There are several ponds on the property; a limestone glade area constitutes the northeast corner of the tract. A small creek flows east to west across the tract north of the center. There are numerous foot trails, some designated and some rogue. An old section of Mann’s Lick road runs northward about midway in the tract. Map #1 from the Blackacre Preserve website provides a general layout of this tract. Map #2 is a topographic map with a NAD83 UTM 16 grid superimposed and the foot trails plotted in various colors. Methods The survey was accomplished by conducting random forays into the area; the routes chosen to best accommodate species that were expected to be in flower. Eight visits were made to the preserve by the author this season between March 20 and July 2. Some collections of plants were made to provide a voucher and determine the species if in doubt. All plants collected reside in the Indiana University Southeast Herbarium (JEF) and carry the author’s collection numbers. All plant collections associated with this survey are summarized in table 2. All locations of collected species and major invasive sites were recorded with a handheld GPS. The open pastures and fields south of the creek [shown in map #1 as Pastures 1 to 4; Front field; Parking Lot Field and Nature Center Field] were paid little attention during the survey as they were apparently not in a native or ordinary fallow state but rather more likely planted with a seed mixture of some sort and or occupied by livestock. Some of the plants observed in these areas are listed however. The survey focus was mainly on the glade area, woods and creek channel in the north half of the property. This survey was conducted under KSNPC permit # BLAC 071610-ext 2011. Nomenclature herein follows the USDA Plants Database. All GPS data provided in this report refer to the NAD83 UTM16 datum and are in units of meters. 2 Results No federally listed or state listed species were observed on the tract. With the addition of spring blooming species this season the list for the Blackacre Preserve was expanded from 240 to 313 herbaceous species. Table 1 provides a summary of these plants with notes on their habitat. Table 2 is a listing of all plants collected from the tract this year. The focus this season was on the spring blooming plants. Although no Kentucky state listed species were found on the property many species that are locally rare, some in fact state listed in Indiana were observed. Of the early species only a few were of any particular interest. Both local varieties of Chaerophyllum procumbens [Chervil] were found on the tract. Variety shortii [Short’s Spreading Chervil] which has hairy fruit pods was found to be common in the woods, particularly in the waterfall ravine area. This may be the first report of the variety for Jefferson County. Variety procumbens [Spreading Chervil] with glabrous fruits was more common in clearings and along the roads. Two species of spring Forget-Me-Not were also found on the preserve. Myosotis macrosperma [Large Seeded Spring Forget-Me-Not] was particularly abundant to the south in the Tyler’s Trace Trail area. Myosotis verna [Spring Forget-Me-Not] was more common on the remainder of the tract and near the glade areas. Nothoscordum bivalve [Crowpoison] was also common in the rocky woods of the waterfall ravine area. An area that may be a small glade remnant was noted in the southeast corner of the tract. This little area located at GPS 628679 mE 4228049 mN was at the end of a short trail branching off the Tyler Trace Trail. The area had an abundance of Eleocharis bifida and Scutellaria australis both of which were found mainly in the glade area. The author did not get a chance to check this area later in the 2011 season; it may prove to be of no interest but bears watching. See map #2. While this included list is extensive and represents a good start, it still must be considered incomplete. Woody plants and shrubs were not included in this survey and many of the below listed collections and those from last season still need careful examination. Compilation of an accurate and complete species list must be an ongoing project. 3 Invasive species The invasive species noted across the tract over the last 2 seasons include: Elaeagnus umbellata Thunb. [Autumn Olive] Euonymus fortunei (Turcz.) Hand. [Climbing Euonymus, Wintercreeper] Lonicera japonica L. [Japanese Honeysuckle] Lonicera maackii (Rupr.) Herder [Amur Honeysuckle] Microstegium vimineum (Trin.) A. Camus [Japanese Stiltgrass] Rosa multiflora Thunb. [Multiflora Rose] Setaria pumila (Poir.) Roemer & J.A. Schultes [Yellow Foxtail Grass] Alliaria petiolata Cav. and Grande [Garlic mustard] Amur Honeysuckle (shrub) is perhaps the worst problem on the tract, but Climbing Euonymus which is spreading throughout most of the wooded areas of the tract is hot on its heels. Japanese Stiltgrass was observed to be heavy in the west central area of the tract, particularly along and north of the creek. A particularly large patch was located at GPS 628055 mE 4228735 mN. Japanese honeysuckle was scattered across the tract but distributed about normally for this area. Garlic Mustard was not found to be unusually abundant either. A few Autumn Olive trees were scattered in the clearings, particularly numerous in the area south of the Dragonfly Pond. Foxtail grasses were scattered across the tract with Yellow Foxtail becoming somewhat common on the glade area. Multiflowered Rose was occasional across the wooded areas of the tract, not abundantly though. 4 Acknowledgements The author would like to thank the Kentucky State Nature Preserves Commission for the opportunity to do this survey and for issuing a plant collection permit.

  • Variability of Anthoxanthum Species in Poland in Relation to Geographical-Historical and Environmental Conditions: Isozyme Variation
    Biodiv. Res. Conserv. 30: 63-93, 2013 BRC www.brc.amu.edu.pl DOI 10.2478/biorc-2013-0011 Submitted 18.04.2013, Accepted 27.06.2013 Variability of Anthoxanthum species in Poland in relation to geographical-historical and environmental conditions: isozyme variation Maria Drapikowska Department of Ecology and Environmental Protection, Poznań University of Life Sciences, Piatkowska 94c, 61-691 Poznań, Poland, e-mail: [email protected] Abstract: Variation of 9 isozyme systems was studied in Polish populations of 3 species of the genus Anthoxanthum: the native A. odoratum s. str. L. and A. alpinum Á. Löve & D. Löve, as well as the alien A. aristatum Boiss. Results of this study show that A. odoratum is characterized by a high isozyme variability of lowland populations, weakly correlated with habitat type, and partial genetic distinctness of montane populations. Moreover, 5 isozyme markers have been identified (Pgi-2, Dia-2, Mdh, Idh, Pgm) for the allopolyploid A. odoratum. Populations of A. aristatum are highly polymorphic (P = 98%). The observed isozyme differentiation of its populations (FST = 0.087) is low and gene flow between them N( m = 5.314) is high. The genetic variation reflects environmental variation only to a small extent and is not significantly related to the phase of chorological expansion of this species. Altitudinal vicariants, A. alpinum and A. odoratum, are characterized by morphological and isozy- matic distinctness, indicating their reproductive isolation. In populations of A. alpinum, polymorphism is high (P = 76.92%), differentiation among populations is moderate (FST = 0.198), and gene flow between populations along the altitudinal transect (Nm = 1.709) is relatively low.

Loudon (Fabaceae) is a tall, herbaceous, perennial legume that is regionally rare in New England. Found most often in dry, open, rocky woods over circumneutral to calcareous bedrock, it has been documented from 28 historic and eight current sites in the three states (Vermont, New Hampshire, and Massachusetts) where it is tracked by the Natural Heritage programs. The taxon has not been documented from Maine. In Connecticut and Rhode Island, the species is reported but not tracked by the Heritage programs. Two current sites in Connecticut are known from herbarium specimens. No current sites are known from Rhode Island. Although secure throughout most of its range in eastern and midwestern North America, D. cuspidatum is Endangered in Vermont, considered Historic in New Hampshire, and watch-listed in Massachusetts. It is ranked G5 globally. Very little is understood about the basic biology of this species. From work on congeners, it can be inferred that there are likely to be no problems with pollination, seed set, or germination. As for most legumes, rhizobial bacteria form nitrogen-fixing nodules on the roots of D. cuspidatum. It is unclear whether there have been any changes in the numbers or distribution of rhizobia capable of forming effective mutualisms with D.
