Preliminary financial evaluation of management regimes controlling Chinese privet in loblolly pine stands.

Abstract

Chinese privet (Ligustrum sinense Lour.) is the most common invasive shrub species in the Southern United States, causing biodiversity and economic losses. This study evaluated several treatments found in the literature and conducted a financial analysis to identify the most cost-effective management regimes for controlling this species in loblolly pine (Pinus taeda L.) stands. Simulated scenarios were created to assess these management regimes. Three components were used: infestation levels, herbicide application methods, and herbicides. For each simulated scenario, the financial impact on land expectation values (LEV) was analyzed. Results indicated that the most cost-effective management regime controlling Chinese privet in loblolly pine stands is to aerial spray with Arsenal AC, followed by a backpack spray 2 years later with the same herbicide. Chinese privet control is economically feasible, and a positive LEV could be achieved for all scenarios. Further research of the same nature with more components and variables is being conducted.
