Invasive species and management

Invasive species are one of the most pressing contemporary ecological issues.  Damages from invasive species, ranging from aquatic invaders like zebra mussels, to insects that attack various tree species and also including mnay other dramatic examples, are extremely large.  A set of steps, from introduction to establishment to spread of the invasive, can be used to break down the process of the invasion.  

We will focus primarily on the issue of spread and control of spread, but that is mainly because of time.  

We will also use this lecture to introduce some basic ideas of bioeconomics.
