Wildlife Damage Management at the County Level: Fresno County, California

A bioeconomic model for optimal control of wildlife damage by migratory small mammal populations is developed under the framework of a nonlinear distributed parameter control problem. The model first simulates the spatio-temporal dynamics of dispersal population by parabolic diffusive Volterra-Lotka partial differential equation and then optimizes a criterion function of present value combined costs of wildlife damage and harvesting. The existence of a unique optimal solution for a finite time problem is proved. An iterative procedure for numerical solution of the Optimality System with parabolic equations of opposite orientations is developed. The theoretical model is applied to a real life problem using biological and economic data for beaver populations under certain simplistic assumptions.

Strategic Program

The National Wildlife Research Center (NWRC) functions as the research arm of Wildlife Services (WS) by providing scientific information on the development of socially acceptable methods for wildlife damage management. NWRC has identified four strategic program goals: (1) developing methods, (2) providing wildlife services, (3) valuing and investing in people, and (4) enhancing information and communication. WS is dedicated to helping meet the wildlife damage management needs of the United States by building on NWRC's strengths in these four key areas. This annual research highlights report is structured around these programs goals.
