I live near the Long Island Sound, in a landscape overrun with invaders from all over the world. My wife spends her free time ripping out Japanese knotweed from our garden. The Connecticut salt marshes are overrun with invasive Phragmites reeds.  Starlings descend on us like a hail storm. So I found it intriguing to discover some scientists who don’t consider invasive species to be all that big a deal compared to other effects we’re having on the environment, like habitat destruction and climate change. In today’s Science Times section of the New York Times, I have an article about some of their recent research, and their critics who think they’re missing the true dangers of invasives.

The article was not based merely on vented spleen. There have been a number of papers published on this issue in recent years. Here are a few…
