Evaluating Cost Effective Control Strategies for dealing with Beaver Infestation in Tierra del Fuego.

In 1947, the non-native species of North American beaver was introduced in the southern
tip of South America, with the goal to encourage fur industry. Since then, beaver population
has spread and grown many fold, resulting in a huge challenge to control its population in
Tierra del Fuego, covering regions in both Chile and Argentina. Primary reasons for their
rapid spread in part include good ecological conditions and lack of natural predators, thus
causing huge ecological damage in the region. This study uses data from Tierra del Fuego on
growth rates, dispersal rate of beaver population and types of available controls to develop
dynamic models of population spread. These models are used to design effective population
control policies that include trapping and hunting. Monetary cost for the implementation of
these controls are considered in order to optimize costs and reduction policies for development
of long lasting strategies.
