Title: From pests to poachers: how much effort should we spend searching for our adversaries?
Date: 7 November 2016
Abstract: Invasive species and illegal exploitation of natural resources are two of the biggest threats to biodiversity, but in order to do anything about them, we must first detect where they occur. In this talk I will present two approaches for determining the right amount of surveillance effort to meet a specified objective. First I will use a cost minimization approach to examine the importance of time-scales when searching for invasive species and then will use a simple system dynamic model to show why inefficiencies in anti-poacher surveillance imply that all proposed management actions to save the African elephant from poaching for ivory will not prevent long term population declines.
