Reminds my if an old timey sayjng—"A weed is just a plant out of place."

And back on topic - Kill 'em all - native, invasive, makes no difference. As I read the expert concensus, after eradication the likelihood of some edge case eco-dependency being revealed should be vanishingly small, whereas the status quo allows millions of homo sapiens to be sickened and or killed.

That seems like easy math to me.

NB: I'm a Southerner (Peach state) so I'll admit I carry a strong, but well earned, hatred of the vile creatures.
