Are invasive plants a threat to native biodiversity? It depends on the spatial scale

Sounds like a couple more good reasons to eradicate the Amur honeysuckle!

Yes, very good reasons to remove amur from your land. When looked at carefully these types of problems with invasives always occur, what ever else may be going on at a local level. So while species may not be extinct from the state or mountain range, they may be disappearing from a particular stream or woodland lot because of the invasives. How long can this go on without intervention? Sooner or later some species will not have a place to get a foothold and will go extinct. Saying the invasive was not the only cause does nothing to save the species.
And even if those species always exist somewhere else what about this small place left in a condition that does not have healthy ecosystem function? |

It should also be mentioned that invasive plants are only one type of invasive species. If they want to see some major biodiversity degradation (not necessarily limited to extinctions) all they have to look at are invasive species like chestnut blight and Dutch elm disease. That's not to pick on the authors or their article, they clearly indicated that their study was limited to invasive plant species causing extinctions. But it is a narrow view of how invasive species harm ecosystems. . .

When looked at as a whole and not limited to extremes, it should be clear to anyone truly looking into the situation just how devasting invasives (flora, fauna, pathogens, etc.) really are to natural habitats around the world. How do we get the word out in a clear and concise way to the masses?
