Took me a while, but I am now ready to accept @EcoInvasions definition of what 'invasive' means: an exceptional ability to colonize, establish & spread, regardless of impact (and regardless of nativeness status)

@JLembrechts @EcoInvasions So, Fagus sylvatica is invasive in Central Europe & Picea abies in Fenno-Scandia? ;)
@JCSvenning @EcoInvasions I might have stept out of line with the 'nativeness', but was trying to include the concept of 'native invaders'. Might not be entirely possible to match both, however...
@JLembrechts @JCSvenning @EcoInvasions Invasive species are inextricably related to competitive release. Non-native species tend to invade when there’s no biological restrictions to their spread. You can envisage similar process of invasion by native species after a massive extinctions but this seems unlikely.
@Araujo_lab @JCSvenning @EcoInvasions Yes, I was thinking along the same line now, the 'spread' part of the definition implies some dynamic changes. Simply successful native species in equilibrium with the emvironment are not invasive, disturbance, then competitive release and rapid spread could make them invasive
