What is an Invasive Species?
Invasive species are non-native species that have been introduced by human intervention, outside their natural range and that has the ability to threaten our native wildlife, cause damage to our environment, economy or human health.
Once introduced, control, management and eradication where possible of invasive species can be very difficult and costly; therefore early detection and reactive measures are desirable.
Most non-native (also known as alien) species do not cause any harm and only a small proportion are considered to be invasive.
