Title Development of models of mallard population dynamics for adaptive harvest

management

Project Description This work involves application of an adaptive approach to management of migratory bird

populations. Adaptive management is an approach to solving the so-called dual control problem of

simultaneously managing a population (a goal for the present) and learning about the functional

relationships between management actions and population status (in order to achieve future

goals). This approach is currently being applied to the annual establishment of mallard hunting

regulations in the United States. The approach also holds promise for use with habitat

management for both hunted and nonhunted species. Work on this topic ranges from the

development of competing management models, to research on methods for updating associated

model probabilities based on a comparison of model predictions with survey results, to work on

solutions to problems in optimal stochastic control.
