Les espèces invasives : Discussion générale. Saving Native Wildlife with “Invasive” Plants. There’s been a lively discussion on permaculturists’ occasional planting of introduced species known to naturalize (or, in loaded terms, invasive species) at this blog.
Some there have disputed that exotics can play critical roles in habitat, and I posted the words below to show that removal of exotics can be very damaging to native wildlife: Here are hard data on introduced plants that have rapidly formed partnerships with native insects, from a paper, “Exotics as Host Plants of the California Butterfly Fauna,” by Sherri Graves and Arthur Shapiro, in Biological Conservation (2003) 110:413-433.
