Oklahoma Native Plant Record Volume 10, December 2010 34 THE VASCULAR FLORA OF HALE SCOUT RESERVATION LEFLORE COUNTY, OKLAHOMA Bruce W. Hoagland Amy K. Buthod Oklahoma Biological Survey Oklahoma Biological Survey and Department of Geography University of Oklahoma University of Oklahoma Norman, OK 73019 Norman, OK 73019 e-mail: bhoagland@ou.edu Keywords: diversity, endemic, inventory, Ouachita Mountains ABSTRACT The Hale Scout Reservation is located in the Ouachita Mountains of southeastern Oklahoma, a region of high plant diversity in the state. A vascular plant inventory yielded 463 species of vascular plants in 288 genera and 99 families. The largest families were the Asteraceae (with 65 species) and Poaceae (56). The flora consisted of 120 annuals, 1 biennial, and 342 perennials. Forty-two non-native species were collected, representing 8.8% of the flora. Sixteen species tracked by the Oklahoma Natural Heritage Inventory were present: Amorpha ouachitensis (S1), Aristolochia serpentaria (S1), Baptisia nuttalliana (S2), Brachyelytrum erectum (S1), Brasenia schreberi (S1), Carex ouachitana (S1), Chionanthus virginicus (S2), Clematis crispa (S1), Didiplis diandra (S1S2), Galium arkansanum (S2), Houstonia ouachitana (S1), Juncus repens (S1), Modiola caroliniana (S2), Monotropa hypopithys (S1), Muhlenbergia bushii (S1), and Ribes cynosbati (S2) (Oklahoma Natural Heritage Inventory, 2010). INTRODUCTION The Ouachita Mountains are a region of high species richness and habitat diversity within the Interior Highlands of the United States (Zollner et al. 2005). The first botanist to visit the Oklahoma Ouachita Mountains was Thomas Nuttall during his expedition from Fort Smith to the Kiamichi River in 1819. Since then, the unique nature of the Ouachita Mountain flora has continued to attract botanists. In April 1913, almost a century after Nuttall, G. W. Stevens visited the Ouachitas and collected 350 plant specimens (Hoagland et al. 2010). Drawing upon botanical records from the region, Zollner et al. (2005) compiled a list of 31 vascular plant species endemic to the Ouachita Mountains. Nineteen of these occur in Oklahoma. In addition, several state rare plant species tracked by the Hoagland, B. & Buthod, A. https://doi.org/10.22488/okstate.17.100075 Oklahoma Natural Heritage Inventory (ONHI; 2010) occur in the Ouachitas. Despite a long history of botanical collecting in the Ouachita uplift, only three floristic lists from the Oklahoma Ouachitas have been published: Smith et al. (1997), Crandall and Tyrl (2006), and Hoagland and Buthod (2009). Smith et al. (1997) inventoried the vascular flora of the McCurtain County Wilderness Area located 66 km southeast of our study site in the Beavers Bend Hills sub-region of the Ouachitas. Fifty-one km west of our study area in Pushmataha County, Crandall and Tyrl (2006) inventoried the vascular plants of Oklahoma Department of Wildlife Conservation‟s Pushmataha Wildlife Management Area. Hoagland and Buthod (2009) inventoried The Nature Conservancy‟s Cucumber Creek Nature Preserve 31 km east in LeFlore County. Oklahoma Native Plant Record Volume 10, December 2010 Hoagland, B. & Buthod, A. 35 The objective of this study was to inventory the vascular plants of the Hale Scout Reservation. The resulting list will be used as an educational tool at the camp and will enhance the knowledge of plant distributions in the Ouachita Mountains. STUDY AREA The Hale Scout Reservation (HSR) is located in the Ouachita Mountains of LeFlore County, Oklahoma (34.736 o latitude, 94.888 o longitude). It is a 192.4 hectare (= 475.4 acre) inholding within the Ouachita National Forest and has been operated by the Boy Scouts of America since 1961 (Boy Scouts of America 2010). Elevation at the site ranges from 251 m to 457 m. The site is drained by Bohannon Creek, which bisects HSR from north to south, and is impounded by 7.7 hectare Bohannon Lake. The climate is subtropical humid (Cf) (Trewartha 1968). Summers are warm and humid (mean July temperature = 26.9 o C; 80 o F) and winters are relatively short and mild (mean January temperature = 2.7 o C; 37 o F). Mean annual precipitation is 122 cm; 48 in., with the highest monthly precipitation occurring in April (13 cm; 5.1 in.) and May (15 cm; 5.9 in., Oklahoma Climatological Survey 2010). The HSR is located in the Ridge and Valley Belt of the Ouachita Mountain physiographic province of southeastern Oklahoma (Curtis and Ham 1979). The region is characterized by broadly folded Mississippian and Pennsylvanian sandstones (Branson and Johnson 1979). Soils on the floodplain of Bohannon Creek belong to Kenn-Ceda complex, which occurs on slopes of 0-2% and are occasionally flooded (Abernathy et al. 1983). The surface layer is dark brown in color and ranges from 18 – 20 cm (7.1-7.9 in.) in depth. The upland soils belong to the Carnasaw-Caston complex and the Carnasaw-Octavia complex. The Carnasaw-Caston complex consists of two units, one on slopes of 4%- 15%, the other on slopes of 15%-35%. These soils are well-drained, with a surface layer of brown stony loam approximately 7.6 cm (3 in.). The Carnasaw-Octavia complex occupies slopes of 35% - 50% and is well-drained, dark grayish brown, and varies from sandy loam to stony loam. METHODS Plant collections were made opportunistically throughout the study area from June 2006 through October 2007. The predominant vegetation associations of HSR were classified according to Hoagland (2000). Vouchers for exotic species were made from naturalized populations only, thus excluding cultivated and ornamental plants. Specimens were processed at the Robert Bebb Herbarium (OKL) at the University of Oklahoma following standard procedures. Manuals used for specimen identification included Waterfall (1973), Smith (1994), and Yatskievych (1999). Origin, either native or introduced to North America, was determined using the United States Department of Agriculture-Natural Resources Conservation Service (2010). Nomenclature and systematics also follow the USDA-NRCS (2010). Voucher specimens were deposited at the Robert Bebb Herbarium at the University of Oklahoma. RESULTS AND DISCUSSION A total of 463 vascular plant species in 288 genera and 99 families were collected at HSR, including seven species of ferns (1.5% of the flora), one gymnosperm (0.22%), 333 dicots (72%), and 123 monocots (26.5%) (Table, Appendix). The Asteraceae and Poaceae had the greatest numbers of species, with 65 and 56, respectively. The largest genus was Carex with 14 species (3%). There were 120 annuals (25.9%), 1 biennial, and 343 perennials (73.9%). Oklahoma Native Plant Record Volume 10, December 2010 Hoagland, B. & Buthod, A. 36 Ninety-four species (27.6%) were trees (49 species), shrubs (31), or woody vines (14). Forty-two species (8.8%) were non-native to North America. Sixteen species tracked by the Oklahoma Natural Heritage Inventory (2007) were encountered: Amorpha ouachitensis (G3QS1), Aristolochia serpentaria (G4S1), Baptisia nuttalliana (G5S2), Brachyelytrum erectum (G5S1), Brasenia schreberi (G5S1), Carex ouachitana (G4S1), Chionanthus virginicus (G5S2), Clematis crispa (G5S1), Didiplis diandra (G5S1), Galium arkansanum (G5S2), Houstonia ouachitana (G3S1), Juncus repens (G5S1), Modiola caroliniana (G5S2), Monotropa hypopithys (G5S1), Muhlenbergia bushii (G5S1), and Ribes cynosbati (G5S2). Species are ranked according to level of imperilment at the state (S) and global (G) levels on a scale of 1 through 5, where 1 represents a species that is critically imperiled and 5 one that is secure (Groves et al. 1995). Galium arkansanum and Houstonia ouachitana are endemic species of the Ouachita Mountains (Zollner et al. 2005). The HSR flora consists of more species than the Cucumber Creek Nature Preserve (with 341 species), McCurtain County Wilderness Area (359), and Pushmataha Wildlife Management Area (447), which is interesting since these sites are larger than the HSR; Cucumber Creek Nature Preserve = 1,333 ha, McCurtain County Wilderness Area = 5,701 ha, and Pushmataha Wildlife Management Area = 7,690 ha. As expected, there are numerous species that occur in both the HSR flora and the other sites; HSR shares 236 shared species with the Pushmataha Wildlife Management Area and 178 with Cucumber Creek Nature Preserve. Smith et al (1997) did not include a species list, so comparison with HSR flora was not possible. Land use and the number of non-native species might account for the greater number of species at HSR. In the case of Cucumber Creek, the site has very little development and consists primarily of second growth, closed canopy forests. Of the three sites, the Pushmataha WMA has the most development for hunting and recreation. The McCurtain County Wilderness Area could be characterized as intermediate. The HSR, however, is heavily developed to maximize potential as a Scouting venue. This is reflected in its number of non-native species (42 species), which is greater than that from the Cucumber Creek Nature Preserve (16), the McCurtain County Wilderness (21), and the Pushmataha Wildlife Management Area (31). Four vegetation associations were identified at HSR. Dry upland forests were the most prevalent natural vegetation type, followed by the extensive area that suffers from anthropogenic disturbance. Although Bohannon Lake occupies a small percentage of the total area at HSR, it supported numerous wetland and aquatic plant species. Descriptions of all vegetation categories follow. 1. Pinus echinata – Quercus rubra – Quercus falcata forest association (PEQRF) This was the predominant upland forest type, but in some locales, P. echinata was absent. In these situations, Q. velutina was the co-dominant. Canopy cover was closed for the most part, but small patches of open woodland did exist. Associated species included Antennaria plantaginifolia, Carya texana, Clitoria mariana, Helianthus hirsutus, Hypericum hypericoides, Scutellaria ovata, Tephrosia virginiana, Vaccinium arboreum, and V. pallidum. Aristolochia serpentaria and Baptisia nuttalliana are species tracked by ONHI that were found in this habitat type. 2. Acer saccharum – Quercus alba – Carya alba forest association (ASQA) This forest association occurred on low and north-facing slopes. Pinus echinata and other xeric tree species were often canopy components, but not dominants. Quercus rubra and Nyssa sylvatica were locally Oklahoma Native Plant Record Volume 10, December 2010 Hoagland, B. & Buthod, A. 37 abundant. Associated species included Agrimonia rostellata, Asclepias quadrifolia, Frangula caroliniana, Fraxinus americana, Geum canadense, Morus rubra, Nyssa sylvatica, Ostrya virginiana, Phlox pilosa ssp. ozarkana, Podophyllum peltatum, Polystichum acrostichoides, and Zizia aurea. Brachyelytrum erectum, Carex ouachitana, Chionanthus virginicus, Clematis crispa, Galium arkansanum, Houstonia ouachitana, Modiola caroliniana, Monotropa hypopithys, Muhlenbergia bushii, and Ribes cynosbati are species tracked by ONHI found in this habitat. 3. Wetland (WETL) Wetland vegetation was restricted to Bohannon Lake and consisted of emergent and floating leaf vegetation. Emergent vegetation occurred along the banks of the lake and consisted of species such as Amorpha fruticosa, Carex crinita, Cornus obliqua, Eleocharis quadrangulata, Hydrolea ovata, Juncus effusus, Polygonum lapathifolium, Sagittaria platyphylla, and Steinchisma hians. The predominant species of floating leaf vegetation were Brasenia schreberi and Nuphar lutea. Associated species included Elodea canadensis, Nymphaea odorata, Myriophyllum heterophyllum, Polygonum hydropiperoides, Potamogeton nodosus, and Spirodela polyrrhiza. Species tracked by ONHI in this habitat were Brasenia schreberi, Didiplis diandra, and Juncus repens. 4. Disturbed areas and old fields (DAOF) Locations, including mown lawns, campsites, roadsides, or sites exhibiting signs of physical disruption, were designated as disturbed areas. Common plants in disturbed areas included Ambrosia bidentata, Andropogon virginicus, Conyza canadensis, Cynodon dactylon, Digitaria sanguinalis, Lespedeza cuneata, Kummerowia stipulacea, Rhus glabra, Sorghum halepense, and Trifolium dubium. Modiola caroliniana is a species tracked by ONHI found in this habitat. ACKNOWLEDGMENTS We thank Priscilla Crawford for field assistance. LITERATURE CITED Abernathy, E. J., K. M. Olszewski, and R.
