Optimal Timing of Investments to Control Honey Mesquite

Abstract

A general economic model to analyze optimal timing of brush control treatments and other range improvements was developed. The model was then applied to investments to control mesquite (Prosopis glandulosa Torr.) invading native rangeland in the Rolling Plains of Texas. Although a positive grass response from mesquite control would be anticipated for 5 years under average conditions, the economic optimum retreatment schedule is only 4 years. An increase in beef price shortens the optimal retreatment schedule, while an increase in treatment cost lengthens the optimal retreatment schedule. Implementing brush control treatments during a year favorable for a high rate of top kill is an important economic consideration.
