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 @EcoInvasions I think those two tree species would fit pretty much any concept of native invader ;) eg cf Ellenberg:
@JCSvenning @JLembrechts @EcoInvasions Otherwise, what you describe as invasive native species seems more subtly captured by Grime’ CRS plant strategies.
@Araujo_lab @JCSvenning @JLembrechts @EcoInvasions Ho, I can see Acer pseudoplatanus in this list from Ellenberg, interesting as this is exactly what we see in the field 😀 Acer pseudoplatanus is so dynamic and spread quite fast beyond its north-western limit in France
@EkoLogIt @Araujo_lab @JLembrechts @EcoInvasions Acer pseudoplatanus is also very success in many forest settings in DK, but not helpful calling it an invader imo. It's just doing what it traits always it to do in a completely normal manner
@JCSvenning @EkoLogIt @Araujo_lab @EcoInvasions If not spreading vigorously, probably not, indeed...
@JLembrechts @JCSvenning @Araujo_lab @EcoInvasions In Picardie region and western France, it is spreading vigorously 😉
@JLembrechts @JCSvenning @Araujo_lab @EcoInvasions And in the UK, it is definitely invasive. Even known, in the past, to cause big delays in trains due to leaves falling on tracks during fall season
@EkoLogIt @JLembrechts @JCSvenning @EcoInvasions In a view from the European south, you have species that invade disturbed land quite vigorously, like Cistus ladanifer, specially after fire. In plant ecology, they are known as ruderals. That’s what they do when competitors are removed.
