Abstract:

Effective management of wild horse populations has proven difficult for land managers. This paper develops and evaluates dynamic optimization models of wild horse management for three nonlethal population control methods: removals, fertility control, and a hybrid method combining removals and fertility control. Two state variables are included in the models to account for horses on the range and horses in off-range holding facilities. The optimization problems are solved and dynamic simulations are generated for each method. The results indicate that a strategic approach to nonlethal wild horse population control has the potential to signifi- cantly improve management efficiency.

Description:

This study develops dynamic optimization models to evaluate alternative non-lethal wild horse managment strategies.
