An important policy decision in managing invasive species is how to allocate resources between activities aimed at preventing the arrival of new pests - including additional arrivals of existing pests - and activities aimed at reducing the damages done by species that are already here. We...

Economic studies have demonstrated that agricultural landowners could mitigate significant quantities of greenhouse gas (GHG) emissions through afforestation. The associated carbon, however, must remain stored in soils or biomass for several decades to achieve substantial mitigation benefits....

We present a conceptual, but empirically applicable, model for determining the optimal allocation of resources between exclusion and control activities for managing an invasive species with an uncertain discovery time. This model is used to investigate how to allocate limited resources between...

Public policy for managing invasive species has largely focused on preventive measures prior to detection (stage 1) and on the use of chemical/mechanical or biological control measures after the establishment and dispersion of the invasive species (stage 2). Optimal management policy depends...

In this paper we examine the issue of permanence in the context of sequestering carbon through afforestation. We develop a dynamic nested optimal control model of carbon sequestration associated with the decision to afforest a tract of land given there are uncertainties associated with fire and...

This research develops a multiregional optimal control model that incorporates regional allocation of a public budget for controlling invasive plants when regionally differential recreation demand functions and species control costs are present. Our equimarginal condition for optimal budget...
