An Invasive Exotic Plant Inventory of Pea Ridge National Military Park
Hinterthuer B. 2003. An Invasive Exotic Plant Inventory of Pea Ridge National Military Park. Technical report NPS/HTLN/P6370010724. Fayettville, AR
No information on current invasive exotic species composition, distribution, and abundance existed for the Pea Ridge NMP prior the inventory. Information is needed for park managers to make appropriate decisions to ensure the long-term sustainability of species and abide by the National Park Service (NPS) mission statement. Surveys were conducted in the fall of 2001, continued through the spring/summer of 2002, and ended in November 2002. Plots were revisited as part of another general plant inventory in the spring of 2003. Invasive exotic plant species presence/absence was assessed within 496-100 meter square plots randomly allocated throughout the park. Percent cover was assessed in a subset of these. Invasive exotic plants located adjacent and en route to plots were also noted.
