Building a spatially explicit management strategy that integrates multiple species of mammals

Research grant

Project Description

Develop a model to predict the density and spread of agricultural damage caused by several species of mammals living in the same area and expanding their distribution. Based on the results of this model we will assess how the limited eradication budgets of local self-governing bodies can be used on each species and at each location, and allocated to achieve the lowest overall risk, under various scenarios of differing uncertainties, and give policy advice about the results to local administrators.
