Renewable Resource Management

Consider a multispecies ecosystem (e.g., predator-prey) that is exploited by different groups of harvesters. Each group will concentrate on a single species. The operation is to be directed by a manager who must set rules for the maximum level of harvesting by each group of harvesters. The manager must set these limits without knowing the specific details of how the harvesters may actually operate under these rules, except that it is assumed that the harvesters will not violate the maximum limits. The manager’s objective is to “maximize” the harvested yield for each species without having any of them become endangered by being driven to unacceptably low population levels.
