Please when posting, if you would add the location of your perspective;
As "from where I'm sitting" adds a dimension to the discussion.

"productive" species into the environment.

Non-native plants and the loss of natural diversity...

> Where I work, in the 100th of 1% of what's left of the great

> plants and animals...some very aggressive...and some introduced by our
> well meaning government many years ago. A dozen non native pasture
> grasses compete with native grasses. Pears, crabapples, regular apples,
> and many other plants grown as ornamentals threaten wetlands..we have
> cotoneaster, rowan, juniper spp., hawthornes (which hybridize with our
> native Crataegus douglasii), pyracantha, and of coarse scotch
> broom...which lumberjacks in the early 20th century noticed invading the

> Conservancy is dedicated to eradicating these pests wherever possible.
> Some will never be completely eradicated and we must live with them. For
