Some of these species might be considered exotic, invasive or naturalised. However, it is exciting to see all of them even if some people might consider them to be non-native. It is always a challenge to gain an understanding as to how an introduced species is impacting native species.

Some of these species may pose a problem, whilst others may harmonise with species that are already established. Read on and see if you have seen any of the species below.
