dc.description.abstract Sullivan, Roscoe. Master of Natural Resources Assessment and Analysis. The Mapping of Nonnative Invasive Plants Leads to an Herbicide Trial of Autumn Olive in Lake Raleigh Woods Nature Preserve A survey of nonnative invasive plants was conducted within the boundary of Lake Raleigh Woods Nature Preserve, a nature preserve on North Carolina State University’s Centennial Campus situated West of Lake Raleigh. This survey revealed that there was an abundance of undesired plants existing within the nature preserve. There were roughly ten acres of autumn olive (Ellaeagnus umbellata) growing in the heart of Lake Raleigh Woods. Without intervention, this nonnative invasive plant could continue to spread and out-compete desired native plant species. To inform management practices, an herbicide trial was initiated to study the effectiveness of different herbicide and application method combinations for controlling autumn olive. The study was a 3 x 4 factorial design with three application methods and four herbicides. Herbicide treatments were: glyphosate, imazapyr, triclopyr and a mixture containing aminocyclopyrachlor, imazapyr, and metsulfuron. Application methods were: cut stump application, foliar application, and basal bark application. A ‘cultural control’ and nontreated check was included for comparison. Treatments were arranged in a randomized complete block design with four replications. Individual experimental units (plots) consist of three autumn olive subsamples. Visual ratings for control and stem count data was collected for statistical analysis. The cut stump treatment was the most effective application method across all herbicides for control of autumn olive, while triclopyr was the most effective herbicide across all application methods. The trial was repeated over two years with nearly the same results.
