| Outline of Final Research Achievements |
Overpopulated mammal populations cause damages to ecosystems and agricultural crops in Japan. We need to develop effective management plans under limited hunting resources. When we determine management plans, we have to deal with various uncertainties such as population size, growth rate, dispersal probability and hunting efficiency due to lack of data. We developed statistical models to estimate population sizes, growth rates, and agricultural damage from spatially-sparse survey data. We also developed a spatially explicit models incorporating anisotropic movement in heterogeneous landscape for the management of deer. We derived optimal allocation of hunting efforts to each management unit under uncertainties to minimize agricultural damage caused by deer, wild boars, and raccoons in Chiba prefecture, Japan.
