Many of these inventories focused on the vertebrate fauna and vascular flora in various units of the NPS system. The NATR has not completed a comprehensive floristic inventory since its establishment as a unit of the National Park Service in 1938. Therefore, as part of this initiative, in August 2004, the S. M. Tracy Herbarium at Texas A & M University, College Station, Texas, was contracted by the National Park Service’s Gulf Coast Inventory and Monitoring Network to conduct an inventory of vascular plants along the entire length of the Natchez Trace Parkway. Inventory Objectives ● Documentation of vascular plant diversity within the parkway’s boundaries – Changes in land use on a local as well as regional level often have negative impacts of the native flora of any given region. The NATR, due to its unique configuration, geographic location, and close proximity to adjacent properties, is particularly susceptible to changes in adjacent land use and commercial development. ● Ascertain the location of endangered or threatened vascular plant taxa - Management of current and future mainternance activities, in addition to parkway construction projects, would 4.11 7.88 * 5.17 10.81 * 4.07 5.23 * 4.38 7.24 *
undoubtedly have negative impacts on taxa that have a limited distribution or highly specific habitat requirements. ● Determine what existing vascular plant taxa within the parkway are considered invasive. The NPS has gone to great efforts to control the invasion of many plant taxa such as; tree of heaven [Ailanthus altissima (P. Mill.) Swingle] and kudzu [Pueraria montana (Lour.) Merr. var. lobata (Willd.) Maesen & S. Almeida] (personal communication Whitworth 2004). This inventory encompassed a parkwide inventory of all vascular plant taxa, with an additional emphasis on plant taxa listed as threatened or endangered on either federal or individual state lists, and identification of taxa considered invasive. The inventory consisted of three primary methods of investigation: 1) a literature review, 2) a herbaria search, and 3) an intensive field inventory. 2.1 Literature Review A review of available literature was conducted to determine any vascular plant taxa that have been previously documented on the NATR. Searches of scientific journals, relevant national, regional, and local floras, and several un-published NPS reports provided by the NATR staff were reviewed for verifiable records of collections within NATR boundaries. 2.2 Herbaria Search A written request for existing records of plant specimens was sent to 4 national, and 38 regional, herbaria. Specimen records were requested from regional herbaria in Alabama (8), Arkansas (6), Louisiana (7), Mississippi (7), Tennessee (9), and Texas (1). The Botanical Research Institute of Texas (BRIT) was included because the collection formerly housed at Vanderbilt University (VDB), Nashville, TN is currently being curated at BRIT. The same request was made to four national herbaria; the New York Botanical Garden (NY), the Smithsonian Institution (US), Harvard University Herbaria (HUH), and the Missouri Botanical Garden (MO) since these larger collections typically house a much wider geographic and taxonomic representation than many smaller herbaria. The request specifically targeted records of any vascular plants and endangered taxa in the states of Alabama, Mississippi, and Tennessee. The search criteria were; 1) any records of specimens collected in the counties through which the NATR traversed, and 2) a listing of any threatened or endangered taxa accounts for those states. The list of herbaria searched and the appropriate herbarium acronyms were taken from Index Herbariorum (IH 2004). 15 Comment [WG1]: Were there any vouchers found as part if this search?
