Public trustees at the state, federal, and tribal level are tasked with ensuring that those responsible for destroying or damaging natural resources sufficiently compensate the public for its loss. Those trustees have the fiduciary duty to maintain and restore the natural resources within the...

This study examines the spatial nature of optimal bioinvasion control. We develop a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal spatial-dynamic control strategies. We find that the optimal...
