Invasives in Other Lands

Post by jamesrobertsmith » Tue Feb 01, 2011 5:45 am

I read a lot about invasives from North America:

The UK also has a severe problem with North American gray squirrels.

Bob,

Thanks for posting this link. I thought it was amusing that in the earlier post about Alianthus, that "The tree of heaven, in popular jargon of these lands, is called "American Nucellare. "Nucellare" because it has a habit and foliage similar to that of a walnut, "American" to indicate their exotic appearance."

I am sure there could be quite the discussion about rabbits being introduced to Australia and their deleterious effects, and various snakes to in the south pacific islands. Of course there are Norway rats all over the world.

Cane toads are another one. And of course those horrible brown snakes invading every island where a military transport lands.

ENTS-
And of course the relatively innocuous house finch from western NA, which has become the new house sparrow at feeding stations in the East and Midwest, and has impacted the native purple finch population.

Recently I read a brief article that mentions that the starling may have been part of the reason that Passenger pigeons went extinct.
