9.1.3 Indicators of potential invasiveness

The success of an introduced species in becoming invasive and harmful to native species and ecosystems depends on certain traits of that species as well as certain characteristics of the invasion site. Traits of a species that are indicators of potential invasiveness include

• wide distribution and abundance in the source region
• high physiological tolerance
• special traits not present in the invaded community
• ecological versatility
• high population growth rates and it correlates high fecundity and short generation time
• rapid dispersal

Invasion success is also determined by the invisibility of a habitat.
