Journal of the Oklahoma Native Plant Society, Volume 5, Number 1, December 2005 Oklahoma Native Plant Record 73 Volume 5, Number 1, December 2005 Crawford & Crawford https://doi.org/10.22488/okstate.17.100040 Additions to the Flora of Garvin County, Oklahoma: Including a Complete Vascular Plant Checklist Priscilla H. C. Crawford and Phillip T. Crawford Oklahoma Biological Survey, University of Oklahoma, Norman, OK 73019 A species list created from the Oklahoma Vascular Plants Database (OVPD) indicated that Garvin County, Oklahoma had been neglected by botanists. Our objective was to collect all vascular plant species encountered during three growing seasons to increase our botanical knowledge of the county. A total of 387 species were collected; 174 of these species had not been previously recorded for Garvin County in the OVPD. As a result, 14 families and 62 genera were added to the known flora of Garvin County. The majority of the species collected during this survey are assigned to five families of flowering plants: Poaceae (70 species), Asteraceae (63), Fabaceae (39), Cyperaceae (17), and Euphorbiaceae (16). Forty eight species (representing 13% of the taxa collected during this study) were not native to the United States; the families Poaceae and Fabaceae (with 18 and 10 species, respectively) exhibited the greatest number of introduced species collected in this survey. Five taxa on the Oklahoma Natural Heritage Inventory working list of rare Oklahoma plants were encountered. This collection effort increased the total number of vascular plant species recorded in the Oklahoma Vascular Plants Database for Garvin County to 628 species. INTRODUCTION During the last few decades there has been a decline in the number of plant specimens deposited in herbaria across the U.S. (Prather et al. 2004). This trend in plant collecting has been evident in Oklahoma as well (Hoagland et al. 2004). Certain areas, such as Black Mesa, Wichita Mountains, Arbuckle Mountains, LeFlore and McCurtain Counties, and the counties housing universities are well represented in the floristic collections of the state. Inconveniently located and less glamorous regions of Oklahoma have been ignored by the majority of botanists depositing plants in the state‟s herbaria, creating gaps in the known geographic distribution of taxa within the state. The objective of our research was to fill an apparent gap in floristic data for south- central Oklahoma. G. W. Stevens made the first collections in Garvin County in 1913, and episodes of plant collecting in Garvin County have occurred in each decade since the 1960s (Figure 1). However, no single effort was made to collect all of the species found in a variety of habitats in Garvin County. Prior to our collection effort only 456 species were documented in the Oklahoma Vascular Plants Database (OVPD) for Garvin County, Oklahoma, compared to over 900 species recorded for neighboring McClain County (Hoagland et al. 2004). We believed that the relatively short OVPD species list for Garvin County was most likely due to a deficiency of plant collecting, rather than a lack of floristic diversity in the county. STUDY AREA The study area consisted of a privately owned farm and cattle ranch which covers 906.5 hectares (2240 acres) in the western portion of Garvin County, approximately 14.5 km (9 mi) south of Lindsay, Oklahoma (Fig. 2). Latitudinal extent ranges from 34.72°N to Oklahoma Native Plant Record Volume 5, Number 1, December 2005 74 34.68°N and longitudinal extent from 97.56°W to 97.52°W. The elevation ranges from 295-365 m (975-1195 ft). Rush Creek, which was straightened in this area in the early 1900s, transects the northernmost portion of the study site, which has been continuously managed for livestock and crop production since 1904. The study site is in the Prairie Parkland Province of the Central Great Plains (Bailey 1995), although approximately 150 hectares (371 acres) has been cleared for cropland or “improved” pasture. Physiographically, the study site is located in the Central Redbed Plains. The soils that dominate the site are loamy alluvium in the floodplain, loamy in the bottomland forest, and loamy clay soils in the upland (Kichler et al. 1982). The parent material is of Permian age and is dominated by shallow-marine, deltaic, and alluvial deposits of red sandstone and shale (Johnson et al. 1972). The study area is located within the Subtropical Humid (cf) climatic zone (Trewartha 1968). Mean annual precipitation is 93.5 cm (36.8 in) with May, June, September, and October being the wettest months (21.6, 10.7, 10.2, and 9.7 cm respectively). The mean annual temperature is 15.8°C (60.4°F); July and August are the hottest months, with average temperatures above 26.7°C (80°F). Temperatures exceed 32°C (90° F) approximately 70 days each year (Oklahoma Climatological Survey 2005). METHODS We conducted our survey during the growing seasons of 2001, 2003, and 2004. Although collections were made throughout the study site, areas for collection focus were selected with field reconnaissance and we returned to those specific areas at regular intervals during the growing season. A few collections were also made randomly throughout the county. The habitat type in which each plant was found was recorded, as was its relative abundance within the study site [see Palmer et al. (1995) for a detailed description of the abundance scale]. Specimens were identified using the following manuals: Waterfall (1969), Great Plains Flora Association (1986), Diggs et al. (1999), and Tyrl et al. (2002). Specimens from the Robert Bebb Herbarium at the University of Oklahoma (OKL) were consulted to confirm the identification of some collections. Nomenclature follows the National PLANTS Database (USDA, NRCS 2004). Voucher specimens for all species and, in certain cases, subspecific specimens were collected and deposited in the Robert Bebb Herbarium. Species were identified as native (originating in North America), introduced (originating outside of North America), or cultivated (species generally found only in cultivation; USDA, NRCS 2004). All non-native and agricultural species were collected from populations that had naturalized or were escaped from cultivation. Rarity status was determined using the Oklahoma Natural Heritage Inventory‟s list of rare plants of Oklahoma (Oklahoma Natural Heritage Inventory 2003). We compared our species list with the plant collection records for Garvin County found in the OVPD (Hoagland et al. 2004). RESULTS and DISCUSSION We collected 471 specimens representing 387 species of vascular plants; 174 of these species were not previously recorded in the OVPD for Garvin County (Appendix I). As a result, 14 families and 62 genera were added to the known flora of Garvin County. The greatest number of species collected during this study are assigned to the Poaceae (70 species), Asteraceae (63), Fabaceae (39), Cyperaceae (17), and Euphorbiaceae (16); these five families represented over 53% of the taxa collected at the study site. The remaining 83 families were each represented by 10 or fewer species. We combined our data with the floristic data found in the OVPD to produce a species list for Garvin County. There have been 628 species collected in Garvin County Crawford & Crawford Oklahoma Native Plant Record 75 Volume 5, Number 1, December 2005 Crawford & Crawford since 1913 (Table 1). The Asteraceae (98), Poaceae (89), and Fabaceae (63) are the three families with the largest number of species collected. These three families represent 40% of the species known to occur in the county. We encountered no federally listed threatened or endangered species. However, we found several species tracked by the Oklahoma Natural Heritage Inventory: Eriogonum alatum (G5 S2S3); Muhlenbergia bushii (G5 S1S2); Quercus sinuata var. breviloba (G5GT S?); Quercus stellata (G5 S?); and Rhynchospora nivea (G4 S2). Species are ranked according to their imperilment at both the global (G) and state (S) levels; on the 5-1 scale, 5 indicates a species is secure and 1 indicates it is imperiled (Oklahoma Natural Heritage Inventory 2003). Because older botanical work generally ignores introduced or “weedy” plants, we expected our collection to have a significantly higher proportion of these species than those of previous collectors. Prior to our study, only 46 species of introduced plants were represented in the OVPD for Garvin County, comprising 10% of the taxa known to occur there. Our collection included 48 introduced species (including 26 species not previously recorded in the OVPD for Garvin County), representing 13% of the taxa collected during this study. Poaceae (18) and Fabaceae (10) were the families with the greatest number of introduced species. We defined eight general habitat types found within the study area. Habitat type was recorded for each species (Appendix I). A brief description of each habitat type follows. Bottomland Forest (BF) Bottomland forest occurred in the floodplain of Rush Creek and along its principal tributaries. Hardwood trees such as Carya illinoinensis, Celtis laevigata, Fraxinus pennsylvanica, Quercus macrocarpa, Q. muehlenbergii, Q. velutina, and Ulmus americana dominated the canopy. The shrub layer consisted of many woody vines, including Passiflora spp., Parthenocissus quinquefolia, Smilax spp. and Vitis spp. Viola affinis, Chasmanthium latifolium, and Elymus canadensis were often found in the herbaceous layer of the bottomland forest. Upland Forest (UF) Upland forests differed from the bottomland forest by having a more open canopy and inhabiting coarser soils with less available moisture. Tree species dominating this forest were: Gleditsia triacanthos, Quercus marilandica, Q. stellata, and Sideroxylon lanuginosum. Common small trees and shrubs were: Cercis canadensis, Cocculus carolinus, Maclura pomifera, Morus rubra, Prunus mexicana, Sapindus saponaria var. drummondii, Symphoricarpos orbiculatus, and Viburnum rufidulum. Native Pasture (NP) Native Pasture occurred in upland areas that were originally open grasslands or areas of Cross Timbers that had been cleared of much of the woody vegetation. Native grasses dominated this habitat type: Andropogon gerardii, Bouteloua spp., Eragrostis spp., Schizachyrium scoparium, and Sorghastrum nutans. Common forb species of the native pasture were Ambrosia psilostachya, Amphiachyris dracunculoides, Desmanthus illinoensis, and Tetraneuris linearifolia. Some native prairie plants found were Asclepias tuberosa, Dalea enneandra, Gaillardia aestivalis, Liatris squarrosa, Ratibida columnifera, and Sabatia campestris. Small patches of the woody shrubs Prunus gracilis and Rhus glabra could be found within the native pasture, as well as two species of cacti (Escobaria missouriensis and Opuntia macrorhiza). Outcroppings of native sandstone hosting a different suite of species occurred within this habitat; many of these species (including Ceanothus americanus, Eriogonum alatum, Euphorbia longicruris, Oenothera macrocarpa ssp. oklahomensis, and Pellaea atropurpurea) were only observed in association with these rock outcrops (RO). Cultivated Pasture (CP) Cultivated pasture was typically found in areas previously inhabited by bottomland forest. These areas were cleared of woody Oklahoma Native Plant Record Volume 5, Number 1, December 2005 76 vegetation and planted in row crops in the late 1800s and early 1900s, and were planted with a monoculture of Cynodon dactylon (Bermuda grass) in the mid-1900s. Many “weedy” and introduced plants could be found within this habitat type. Other grasses encountered included Bromus spp., Cenchrus spinifex, and Setaria viridis. Typical forbs found in the cultivated pasture were Capsella bursa-pastoris, Galium aparine, Geranium carolinianum, and Lamium amplexicaule. Disturbed (D) Disturbed areas occurred throughout the study site and included roadsides, edges of cultivated fields, mowed lawns, areas experiencing heavy cattle usage (near feeding areas, stock tanks, or shade trees) and other areas exhibiting signs of physical disturbance. Disturbed areas share many species with the cultivated pasture habitat. Common forb species encountered were Ambrosia trifida, Cirsium undulatum, Conyza canadensis, Cucurbita foetidissima, Grindelia papposa, and Solanum elaeagnifolium. Aegilops cylindrica, Eragrostis cilianensis, Poa annua, and Sorghum halepense were grasses typical of disturbed areas, as were the escaped cultivated plants Secale cereale and Triticum aestivum. Riparian (R) The riparian zone was found along Rush Creek and its principal tributaries. Acer negundo, Celtis laevigata, Salix nigra, and Ulmus americana were the most abundant arborescent species in the riparian zone; Tamarix chinensis and Salix exigua were common along Rush Creek. Fruticose and herbaceous species abundant in the riparian zone included Amorpha fruticosa, Cephalanthus occidentalis, Erigeron philadelphicus, Eupatorium serotinum, Symphyotrichum oolentangiense, and Teucrium canadense. Seeps (S) Seeps occur sporadically within the native pasture, in areas where sloping rock strata carrying ground water from higher elevations intersect the soil surface. The flora of these seeps was conspicuously different from that of other wetland areas within the study site and that of the surrounding pastureland. This flora was dominated by graminoids, including several genera of sedges and rushes (Cyperus, Eleocharis, Fuirena, Juncus, Rhynchospora, Schoenoplectus, and Scirpus). A few grass species also occurred in this habitat (Andropogon glomeratus, Panicum anceps, and P. virgatum), as did several dicotyledonous forbs (Lobelia siphilitica, Marshallia caespitosa, and Valerianella amarella). Wetland and Aquatic (WA) Wetland and aquatic habitats were formed in and around farm ponds, beaver ponds on small drainages, springs, and in small depressions in native and cultivated pastures. Farm ponds and small depressions in pastures were typically bordered by a narrow fringe of herbaceous species common to frequently-flooded and disturbed habitats, and were subject to frequent trampling by cattle. The flora of these areas included Alopecurus carolinianus, Ammannia coccinea, Echinochloa crus-galli, Eclipta prostrata, Leucospora multifida, Mollugo verticillata, Phyla lanceolata, and Symphyotrichum subulatum. The few springs within the study site and several small impoundments created by beavers (Castor canadensis) on unnamed tributaries of Rush Creek were relatively undisturbed; these areas were flanked by woody vegetation similar to that of the above-described riparian zone. The beaver ponds were bordered by a narrow fringe of herbaceous vegetation, including Bidens frondosa, Equisetum hyemale, E. laevigatum, Leersia oryzoides, L. virginica, Leptochloa fusca, Polygonum spp., and Ranunculus sceleratus. The springs were vegetated with the aquatic plants Potamogeton nodosus, Rorippa nasturtium-aquaticum, and Samolus valerandi.
