2008 SOUTHEASTERN NATURALIST 7(3):527–540 The Vascular Flora of the Coon Creek Forever Wild Tract, Tallapoosa County, Alabama T. Wayne Barger1,* and Dan Tenaglia2 Abstract - The Coon Creek Forever Wild Tract (CCFWT) is an area of approximately 130 ha that was purchased by the State of Alabama Forever Wild Program on February 1, 1995. The CCFWT lies 45 km west of Auburn, AL with the main tributary, Coon Creek, dissecting the tract and eventually emptying into the Tallapoosa River. The site is managed by the Alabama Department of Conservation and Natural Resources with an emphasis on recreational use, habitat management, and rare species protection. A fl oristic study of this area was conducted from March 2006 through May 2007. A total of 503 species from 319 genera and 114 families were collected, with 195 species being county records. Asteraceae was the largest family with 74 species. Poaceae, Cyperaceae, and Fabaceae were the next largest families with 45, 31, and 31 species, respectively. Carex was the largest genus represented with 15 taxa. Introduction In 1992, the Forever Wild Program was established by an Alabama constitutional amendment (Satterfield and Waddell 1993) to provide a mechanism for purchasing land from willing landowners to provide public recreation and conservation of vital habitat. Since its inception, this program, managed by the Alabama Department of Conservation and Natural Resources (AL-DCNR), has purchased lands for general recreation, nature preserves, and additions to wildlife management areas and state parks. For each Forever Wild land tract purchased, a management plan laying out guidelines and recommendations for the tract must be in place within a year of acquisition. On February 1, 1995, the Coon Creek Forever Wild Tract (CCFWT) was purchased by the state of Alabama as the third Forever Wild property. This study represents the first systematic inventory of the vascular fl ora on the tract and provides many county records for the poorly surveyed fl ora of Tallapoosa County. Description of the Coon Creek Forever Wild Tract The 130-ha CCFWT is located in east-central Alabama in rural, southern Tallapoosa County (Fig. 1). Tallapoosa County had an estimated population of 40,717 in 2005 and has an area of 1860 km2 (US Census Bureau 2006). Located 6.4 km north of Tallassee (Elmore County) and 45 km west of Auburn (Lee County), the CCFWT was acquired to provide the public with outdoor recreational opportunities, a nature preserve, and an environmental education study area. 1State Lands Division, Natural Heritage Section, Department of Conservation and Natural Resources, 64 North Union Street, Montgomery, AL 36130. 21416 Victoria Avenue, Opelika, AL 36801. *Corresponding author - wayne_barger@yahoo.com. 528 Southeastern Naturalist Vol.7, No. 3 The CCFWT is located just east of the Tallapoosa River with Yates Dam located 2.4 km to the south of the property. An old concrete boat ramp allowing access to narrow Yates Lake through the southern edge of the property is the only developed area on the site, with the exception of old woods roads and a narrow paved road along the southern section of the property. The northern portion of the study area can be accessed via a graded county dirt road that runs along a portion of the northern boundary. When compared to the surrounding area’s land use or other area lakes (such as Lake Martin), Yates Lake is relatively isolated and there is little encroaching development. This lack of development is partially due to the property having one mindful land steward from 1961 until the time of its purchase by the state in 1995. Though the CCFWT technically falls in the Piedmont (Southern Outer Piedmont Ecoregion), the tract has many characteristics common to the Coastal Plain (Fall Line Hills Ecoregion). The vegetation and terrain generally consists of heavily wooded oak-hickory forest lands with rolling hills sloping into and surrounding the mouth of Coon Creek. Elevation ranges from 105 m to approximately 182 m above sea level, with slopes of near 15% present in places. The major soil association of the area is Gilead- Norfolk-Greenville and is described as being comprised primarily of pacolet Figure 1. Location of the Coon Creek Forever Wild Tract in Tallapoosa County, AL. Yates Dam (not shown on the map) backs up the Tallapoosa River to create Yates Lake. 2008 T.W. Barger and D. Tenaglia 529 sandy loam surface soils with clay loam subsoil, and secondarily of sandy surface soils and loamy sand subsoil (USDA NRCS 2007). The climate for the area averages a July high of 33 oC and a January low of 1 oC; rainfall for the area is approximately 134 cm (54 inches) per year, with March being the wettest month and October being the driest (The Weather Channel 2007). The number of frost-free days (growing season) averages 234. Coon Creek is the main drainage through the CCFWT, fl owing east to west, and eventually emptying into the Tallapoosa River. Several smaller creeks also extend into the CCFWT’s boundary, each eventually emptying in to Coon Creek. Backwater from Yates Lake covers approximately 9 ha of the 130-ha tract, with approximately 4 additional hectares being marshland. Classification of forested plant communities on the CCFWT in 1995 showed the following community-type percentages: 17% upland pine, 31% mixed pine/hardwood, 36% upland hardwood, 14% intermediate hardwood, and 2% bottomland hardwood (State Lands Division, Department of Conservation and Natural Resources, Montgomery, AL, unpubl. data). This breakdown accurately depicts the community types and percentages currently present. Oak-hickory is the primary climax forest, with scattered Pinus taeda L. (Loblolly Pine) being the predominant pine species. However, there is a natural inclusion of P. palustris P. Mill (Longleaf Pine) on the north side of the property. Historical Land Use Historically, land use of the CCFWT was documented to have supported the turpentine industry that was once widespread across the longleaf forests of the southeastern US. Longleaf Pines were the species typically utilized for sap because of their plentifulness, long life span, prolific sap fl ow, and ability to withstand injury. From the mid-1800s until the turn of the century, collection of pine sap for use in conversion to turpentine or use in naval stores was a vast industry. This natural resource was primarily derived from the Longleaf Pines that covered the southeastern US, but sometimes also employed other species such as Pinus elliottii Engelm. (Slash Pine). The discovery of a “catface” (the name for the resulting marks made on pine trees in an effort to collect the sap) and several turpentine collection pans indicate that Longleaf Pines may have been more prevalent around the CCFWT than they are today. Methods The systematic collection within the CCFWT was conducted from March 2006 through May 2007. Methodology for surveying the study area was performed utilizing a modified meandering method similar to that of Goff et al. (1982). When possible, plants were collected in a non-destructive (top-snatched) manner for plant populations that were sampled. Because of the relatively small size of the CCFWT, the natural divisions of the property, and the frequency of surveys, the entire tract was thoroughly sampled. 530 Southeastern Naturalist Vol.7, No. 3 Voucher specimens were collected and identified by the authors and subsequently deposited at the Anniston Museum of Natural History, part of the Jacksonville State University herbarium collections (JSU). Verifications were made by the museum’s curator of collections, Dan Spaulding. Duplicates were deposited at Troy Herbarium (TROY). Identifications were determined using the following: Flora of the Carolinas, Virginia, Georgia and Surrounding Areas – online working draft version, August 9, 2006 (Weakley 2006); Manual of the Vascular Flora of the Carolinas (Radford et al. 1968); Manual of the Grasses of the United States. Volumes I and II (Hitchcock 1971); Guide to the Vascular Plants of the Florida Panhandle (Clewell 1985); Aquatic and Wetland Plants of the Southeastern United States. Monocotyledons (Godfrey and Wooten 1979); and Aquatic and Wetland Plants of the Southeastern United States. Dicotyledons (Godfrey and Wooten 1981). Results and Discussion Plant survey summary A total of 503 species representing 319 genera and 114 families were collected from the CCFWT. Of these, 195 were ascertained to be county records for Tallapoosa County (Kartesz 2007). Asteraceae was the largest family with 74 species. Poaceae, Cyperaceae, and Fabaceae were the next largest families with 45, 31, and 31 species, respectively. Carex represented the largest genus with 15 taxa. Flowering plants comprised 96% of the fl ora, with dicots making up 72% and monocots comprising 24% (Appendix 1). Ferns and allies accounted for another 3%, and conifers made up 1% of the total vegetation sampled. Thirty-five species, or 7% of the species composition, were introduced species to the fl ora. No members of Lycopodiophyta were discovered during vegetation sampling. Rare plant species Three species of special interest were collected during this study. They are: Matelea baldwyniana (Sweet) Woods. (Baldwin’s Milkvine), Croomia paucifl ora (Nutt.) Torr. (Croomia), and Baptisia megacarpa Chapman ex Torr. & Gray (Apalachicola Wild Indigo). These species are designated by NatureServe as G3, G3, and G2, species respectively (NatureServe 2007). The G3 designation indicates that a species is “vulnerable range-wide,” and G2 indicates that a species is “imperiled range-wide.” Matelea baldwyniana is a twining, perennial herbaceous vine that has mostly heart-shaped leaves that are opposite in articulation. The fl owers are approximately 1 cm wide with strongly to moderately twisted petals that are creamy-white. Anthesis for this site was mid-April. This species is typically found on dry to slightly mesic slopes over calcareous bluffs and was once considered for listing as an endangered species. However, populations were considered too abundant for this designation. Baldwin’s Milkvine was historically found in four Alabama counties (Barbour, Clarke, Monroe, and 2008 T.W. Barger and D. Tenaglia 531 Wilcox), however each of those populations are considered extirpated (Mohr 1901). Ironically, Mohr (1901) recognized this taxon as being among the rarest in the south. Verification of this species in Tallapoosa County marks a state record for rediscovery of the species. Prior to this study, the plant was only known in Missouri, Oklahoma, Arkansas, and two Florida counties. Croomia paucifl ora is an herbaceous perennial member of the Stemonaceae, which is comprised of four genera and approximately 35 species. There are only 3 species of Croomia worldwide, with C. paucifl ora being the sole species found within the US (Whetstone 1984). Currently, C. paucifl ora has a limited distribution outside Alabama, occurring in only one Louisiana parish, two Florida counties, and eight Georgia counties. In Alabama, Croomia occurs in 25 counties, extending from the upper Coastal Plain to Harper’s discovery in the lower Appalachians (Harper 1942). Found mostly in moist, rich forests with common mesophytic forest indicators such as Fagus grandifolia Ehrh. (Beech) and Tilia americana L. (Basswood), anthesis for Croomia in our area is mid to late-April. Croomia was also once a candidate species for federal listing under provisions of the Endangered Species Act; however, listing was denied because the plant was found to be too abundant in Alabama (Patrick et al. 1995). In 1983, Kral noted Baptisia megacarpa as a “rare or threatened plant species.” Occurring mostly in moist forest fl oodplains and lower wet slopes, Apalachicola Wild Indigo is endemic to three Georgia counties, seven Florida counties, and 10 Alabama counties. It is considered imperiled or critically imperiled throughout its distribution and is regarded as being particularly susceptible to disturbance (Nelson 2005). The present discovery is near the northern limit for the distribution of the species, with only one known location lying further north. Anthesis for B. megacarpa is early to mid-May for this location. Relatively little information has been published regarding this uncommon species. Other species of interest, because of state or distributional rarity, included: Agalinis tenella Pennell (Ten-lobe False Foxglove) G4; Celastrus scandens L. (American Bittersweet) G5; Crataegus pulcherrima Ashe (Beautiful Hawthorn) G3; Sida elliottii Torr. & Gray (Elliott’s Fanpetals) G4; and Verbesina aristata (Ell.) Heller (Coastal-plain Crownbeard) G4. Exotic plant species Thirty-five non-native plant species were collected on the CCFWT. This group accounts for approximately 7% of the total species observed. Other regional fl oras have had slightly higher percentages of non-native plant species; however, the areas surveyed were generally much larger than the 130 ha from the present study: 2528 ha of Lake Guntersville State Park yielded 17% non-natives (Spaulding 1999); 28,329 ha of Talladega Ranger District, Talladega National Forest yielded 12% non-natives (Ballard 1995); and 1101 ha of Cheaha State Park yielded 10% non-natives (Bussey 1983). While this study did not focus on quantitative measurements of plant coverage, the observed land area covered by these non-native plants was relatively small. 532 Southeastern Naturalist Vol.7, No. 3 The most commonly encountered non-native plant species, in order of abundance, were: Albizia julibrissin Durazzini (Mimosa), Microstegium vimineum (Trin.) A. Camus (Japanese Stilt Grass), Lespedeza cuneata (Dumont) G. Don (Chinese Lespedeza), Melia azederach L. (Chinaberry), Pueraria montana (Lour.) Merr. (Kudzu), Wisteria sinensis (Sims) Sweet (Chinese Wisteria), and the combined Trifolium spp. Acknowledgments The authors thank Curtis Hansen and the anonymous reviewers for their helpful comments in crafting this manuscript.
