Chris Oddie is a passionate member of the Lithgow Environment Group (LEG). With other members of LEG, she became increasingly concerned about the growing number of invasive Indian Myna birds proliferating in Lithgow. Mynas are listed among 100 of the world's worst invasive species by the World Conservation Union.

The story of Lithgow Environment Group is a saga spanning nearly two decades of their heroic struggle against fire, local habitat destruction, weak government legislation and in particular, irresponsible mining practices.
