An example of imported species in the San Francisco Bay Area 
is the French garden snail,
imported (according to local folklore at least) as food;
it has taken over in a big way and is a major pain for any
causal gardener.  A more serious disaster is the polyester
garbed tourist, imported from Podunk Iowa, which has driven most
native species to distraction.
