G'day everyone,

It comes back to the precautionary principle in both directions.

Weeds should not be planted without very good evidence in their favour.

It has been reported, however, that a couple of near extinct parrots,
Turquoise Parrot and Long-billed Corella, have come back from the brink
because of adoption of weeds in their diet. Another post points out the
shelter value of Gorse and Blackberry to which can be added Boxthorn. As
Michael Norris well knows, Superb Fairy-wren has a tough time of it in
suburban Melbourne but can often hang on around this noxious South African

If it were possible to eradicate weeds overnight it would have many
undesirable side-effects.

Do you mean something exotic?
