When I walk out on the bottom lands beneath my home in the hills of northwest Oregon, I am keen to take note of such troublesome invasive species as Nutria (or Copyu, Myocastor coypus), American Bullfrog (Lithobates catesbeianus), and Scotch Broom (Cytisus scoparius). However as I’m doing so, I’m passing by a number of other invasives without giving them so much as even a passing glance.
