A total of 388 taxa in 80 families were collected. Two hundred and fifty-seven genera, 361 species, and 27 infraspecific taxa were identified. The largest families were the Poaceae with 66 taxa and the Asteraceae with 55 taxa. Fifty-seven taxa were planted or non-native to the U.S. (14.7 % of the flora). Four taxa tracked by the Oklahoma Natural Heritage Inventory were found. INTRODUCTION AND STUDY AREA The Kessler Atmospheric and Ecological Field Station (KAEFS) at the University of Oklahoma was established on properties donated by Dr. Edwin Kessler from 1988 to 2011 (http://kaefs.ou.edu/). Located approximately 28 km southwest of the Norman campus, KAEFS promotes and facilitates collaborative research and learning. The station hosts both formal and informal courses, workshops, and numerous meteorological and biological experiments, including a long-term global warming experiment. The goal of this work was to compile a complete list of vascular plant taxa present at the site to assist current and future KAEFS researchers in species identification and documentation. KAEFS occupies 146 ha in McClain County in central Oklahoma approximately 13 km from the town of Washington (Figure 1). Latitudinal extent ranges from 34°58’15.99”N to 34°59’10.61”N and longitudinal extent from 97°30’32.88”W to 97°31’42.63”W. Physiographically, the site is located within the Western Red-bed Plains geomorphic province, which consists of gently rolling hills of red sandstone and shale of Permian age (Curtis et al. 2008; Johnson 2008). Two soil associations predominate at KAEFS: the Nash-Lucent- Grant (deep to shallow, gently sloping to moderately steep loams over sandstone uplands) and the Port-Pulaski-Keokuk (deep, nearly level loamy soils on floodplains; Moebius and Sparwasser 1979). KAEFS is located within the subtropical humid (Cf) climate zone (Trewartha 1968), with a mean annual temperature of 16oC. Low temperatures (to 3oC) occur in January, while the warmest temperatures occur in July (to 28oC; Oklahoma Climatological Survey 2016). The month of May is typically the wettest, with an average precipitation of 13.5 cm. Mean annual precipitation is mailto:amybuthod@ou.edu http://kaefs.ou.edu/ 46 Oklahoma Native Plant Record Volume 16, December 2016 Amy K. Buthod and Bruce W. Hoagland 96.7 cm (Oklahoma Climatological Survey 2016). Elevation ranges from 332 m to 343 m. The dominant potential vegetation type is tallgrass prairie (Duck and Fletcher 1943). The KAEFS property has a long history of farming and livestock grazing. The first homestead was established in 1904, and crops such as cotton, sorghum, and wheat were grown on the property up until the early 1970s. The property has an equally long history of cattle grazing, and a small herd still roams the grasslands today (http://kaefs.ou.edu/). A population of the Mediterranean basin native Carthamus lanatus L. was discovered at the site in the mid- 1970s and grew to approximately 3000 plants by 1989. It was eradicated in the early 1990s with a strict regime of hand-pulling (Kessler unpublished). METHODS Vouchers of vascular plant taxa encountered at KAEFS were made throughout the growing seasons (March through October) of 2013, 2014, and 2015. Vouchers for U.S. non-native or planted taxa were only collected from naturalized populations. Specimens were processed according to standard procedures. In addition to these vouchers, collections from an earlier, unpublished study were also examined to see if additional taxa had been collected. Manuals used for identification included Diggs et al. (1999) and Tyrl et al. (2015). Identifications were verified by comparison with specimens from the Robert Bebb Herbarium at the University of Oklahoma (OKL). Duration, growth habit, vegetation type, and nativity were determined using the PLANTS database (USDA-NRSC 2016) and Taylor and Taylor (1991). Classification and nomenclature follow Angiosperm Phylogeny Group III (Stevens 2001 onward) and the Integrated Taxonomic Information System (ITIS 2016). All specimens were deposited at OKL. RESULTS AND DISCUSSION A total of 388 taxa in 80 families were collected (Appendix). Two hundred and fifty-seven genera, 361 species, and 27 infraspecific taxa were identified. Two hundred and fifty-two taxa were perennials; there were 133 annuals and three biennials. The largest families were the Poaceae with 66 taxa and the Asteraceae with 55 taxa. Two-hundred and fifty-one taxa were forbs, and 91 were graminoids. There were 26 trees, 12 shrubs, and eight vines. Four taxa tracked by the Oklahoma Natural Heritage Inventory were found (Table 1). Three- hundred and seventy-nine of the 388 taxa were collected by the authors. Nine additional taxa were found during an earlier survey by former KAEFS researcher Becky Sherry. Fifty-seven taxa were planted and naturalized or non-native to the U.S. (14.7 % of the flora). Fifty-six of these were non-native. This number is high when compared to surveys from other Oklahoma grassland-dominated sites (Table 2), but it is not surprising given the land use history at KAEFS. Taxodium distichum, which is native to southeastern Oklahoma, was also found but was planted by the former property owner and has since naturalized. The Poaceae had the greatest number of exotic taxa with 13. The Fabaceae followed with nine exotics. Carthamus lanatus, reported from the property as late as 1991, was not relocated (Kessler 1987; Hoagland et al. 2012; Kessler unpublished). The predominant vegetation type encountered at KAEFS was the Schizachyrium scoparium-Sorghastrum nutans association, a herbaceous vegetation type found throughout Oklahoma on uplands with well-drained soils. Associated taxa included Amorpha canescens, Dichanthelium oligosanthes var. oligosanthes, Panicum virgatum, and Symphotrichum ericoides var. ericoides (Hoagland 2000). http://kaefs.ou.edu/ Oklahoma Native Plant Record 47 Volume 16, December 2016 We encountered three community types dominated by woody plants at KAEFS. The Populus deltoides-Ulmus americana-Celtis laevigata forest association was found on the bottomlands surrounding the property’s larger order streams. This vegetation type is found frequently throughout the state (excluding the panhandle) on moist or wet soils along riparian corridors. Associated taxa found in this association included Carya illinoinensis, Symphoricarpos orbiculatus, and Toxicodendron radicans (Hoagland 2000). Small stands of Quercus muehlenbergii were encountered in mesic situations. Associated taxa included Amphicarpaea bracteata, Desmodium glutinosum, Elephantopus carolinianus, and Phryma leptostachya. Upland woodlands of the Juniperus virginiana- Schizachyrium scoparium association intergraded with the grasslands and the riparian zones of low order streams. This vegetation type is common throughout Oklahoma (excluding the panhandle) and is the product of fire suppression and land-use change. Associated taxa included Andropogon virginicus, Cirsium altissimum, Quercus marilandica, and Smilax bona-nox (Hoagland 2000). Herbaceous wetland vegetation was restricted to ponds and creek channels. Plants found in this type included Coleataenia anceps, Juncus torreyi, Lycopus americanus, Teucrium canadense, and the invasive aquatic Myriophyllum spicatum. Disturbed areas included an area around a barn, the parking lots, and gravel roads. Plants in these areas included Mollugo verticillata, Muhlenbergia paniculata, Polygonum ramosissimum, and Solanum rostratum. Figure 1 The Kessler Atmospheric and Ecological Field Station.
