The Black Wattle (Image by Google)
Except for humans, apparently the most dangerous species out there is the Black Wattle or Black Acacia (Acacia mearnsii). This plant is originally from Australia, and was introduced in several parts of the globe in the 70's to recover riparian areas and as ornamentation. The results were catastrophic.
The problem is that this Acacia alters the soil nutrients, generating substances that prevent the germination of the native species where it is planted. It can only be eliminated by powerful herbicides, which will also affect the other nearby plants as well, practically destroying the vegetation of the area.
