Destructive and Invasive Species

The World Conservation Union (I U C N) has released a list of the world's top 100 most destructive invasive species. The list includes plants, micro-organisms, insects, mammals, birds etc. I have included species relevant to us in the list below, and where they appear in the ranking.

Remember this is a global ranking, and yet these species still rate in the top 100 of thousands.

In Australian terms these species would rank very high, possibly all within the top twenty.

Specie	World Ranking
Indian Myna	2
Feral Goat	17
Red Deer	22
Domestic Cat	38
Rabbit	67
European Starling	89
Feral Pig	90
