3.0 RESULTS AND DISCUSSION 3.1 Literature Search 3.1.1 Review of National Park Service Sources Although there has not been a comprehensive inventory of vascular plants within the NATR, a number of smaller floral surveys have been conducted. However, the emphasis of these reports was limited to either localized sites or specific plant groups based on growth form and rare taxa. Beginning in the mid 1940’s, and continuing intermittently through the mid 1960’s these studies accumulated approximately 1900 specimens, representing 1021 taxa. With data collected at specific localities, these collections represent an initial attempt to inventory the NATR by park naturalists, associated staff, and associated independent contractors. In 1963 park naturalist Donald Black developed an Illustrated Guide to the Climbing Plants of the Parkway (Black 1963). The stated purpose of this guide was to “provide a layman-type picture guide for quick identification of climbing plants found along the parkway” (Black 1963). Probably used mainly by park staff, the illustrations appear incomplete and were apparently drawn from dried herbarium specimens. Black (1963) stated in the introduction to the guide that “a more comprehensive manual to all parkway taxa was in progress” but as far as can be determined this was never completed. In 1991, a preliminary vegetation survey was conducted at the Chickasaw Village site located in Tupelo, Mississippi (Wieland 1994). The purpose of this survey was to determine the suitability of this site for prairie restoration. Plots surveyed as part of the survey identified 107 taxa. In 1995, the Tennessee Chapter of the Nature Conservancy (TNC) was contracted to conduct a biological survey of the flora, fauna, and ecological associations along the NATR from Highway 32 in northeast Mississippi to Leipers Fork, Tennessee. This survey covered approximately 130 miles of the Parkway’s 445 mile length (TNC 1995). Results of this report are summarized in section 3.3.7 and in greater detail in Appendix C. The most recent study, completed in 1996, focused on the presence of three threatened or endangered species in the proposed location of the Southern Parkway Terminus. The goals of the study were to delimit the distribution of these taxa in the area surveyed and determine the approximate the size of 18
any extant populations (Rosso and Reed 1996). Results of this report are summarized in section 3.3.7 and in greater detail in Appendix C. 3.1.2 Review of Tennessee, Alabama, and Mississippi State Floras Tennessee - According to Frodin (2001), Gattinger published The Flora of Tennessee and a Philosophy of Botany in 1901, which included a listing of the vascular plants as well as some remarks on local range and habitat; however, there was no usable key. The most current listing of vascular plants of Tennessee was published by Wofford and Kral (1993). Also published by Wofford and Chester (2002) was the Guide to Trees, Shrubs, and Woody Vines of Tennessee, which proved to be an invaluable resource during the course of this project. Alabama - The only flora published for Alabama is Mohr (1901) Plant Life of Alabama. However, being published in 1901, it is currently outdated. A checklist of vascular plants was published in 2002 by the Department of Biological Sciences at Auburn University (Morton et al. 2002). The collections of the John D. Freeman Herbarium at Auburn University and the University of Alabama Herbarium were combined to produce a checklist of 201 families, 1047 genera, and 3544 taxa (Morton et al. 2002). A treatment of ferns of Alabama was published by Dean in 1969, which included keys as well as county distribution data (Frodin 2001). Mississippi - There is currently no vascular flora available for the state of Mississippi. Treatments of several small families have been produced and published in journals such as Castanea and Phytologia by S.B. Jones (Frodin 2001). A Preliminary Checklist of Mississippi Plants (McCook and Kartesz 2004) is currently being developed by staff at the University of Mississippi’s Thomas H. Pullen Herbarium. 3.1.3 Review of Regional (Southeastern United States) Floras The first major floristic work in the southeastern United States was by John Darby. Frodin (2001), reports that Darby produced A Manual of Botany in 1841 and Botany of the Southern States in 1855. The Manual of the Southeastern Flora by Small, first published in 1903, was a compilation of data from over 50,000 specimens as well as literature provided by other botanists in the region (Frodin 2001). Small’s Manual of the Southeastern Flora is still one of the few major floras for the area, although it is mostly outdated now due to numerous nomenclatural changes. There has been little work at the state level with the exception of Mohr (1901), Plant Life of Alabama. This work was published as part of the Geological Survey of Alabama by Eugene Smith after Mohr’s death. 19
