What are the 4 traits of invasive species?

Common invasive species traits include the following:

• Fast growth.
• Rapid reproduction.
• High dispersal ability.
• Phenotype plasticity (the ability to alter growth form to suit current conditions)
• Tolerance of a wide range of environmental conditions (Ecological competence)

Is grass invasive or non-native species?
