100 of the World's Worst Invasive Alien Species

Ant writes "100 of the World's Worst Invasive Alien Species list says: 'Invasive species have been recognised globally as a major threat to biodiversity (the collected wealth of the world's species of plants, animals and other organisms) as well as to agriculture and other human interests. It is very difficult to choose 100 invasive species, from around the world, that really are "worse" than any others. Species and their interactions with ecosystems are very complex. Some species may have invaded only a restricted region, but have a huge probability of expanding, and causing further great damage (e.g. see Boiga irregularis: the brown tree snake). Other species may already be globally widespread, and causing cumulative but less visible damage. Many biological families or genera contain large numbers of invasive species, often with similar impacts; in these cases one representative species was chosen. The one hundred species aim to collectively illustrate the range of impacts caused by biological invasion.'"

It seems we would be on top of the list.

C'mon, Humans have got to rank someplace on that list.

First Post!

Forgot one

I would say:

1) Homo Sapiens

To quote the entry: "few single species occupy as many diverse environments as humans"

Nah, homosapiens should have been #43... The list is alphabetical.

For places where cats are not normal, like Australia and other islands, cats have caused a huge amount of damage to the native fauna. Cats are wiping out small animals and birds, either through predation or through competition.
