Biocontrol: Fighting Invasives with...Invasives

 We kick off the second season of NHPR's newest show, Outside/In, with a discussion of  biological control: using non-native species to combat destructive invasive pests and plants that are decimating a local species.  It's the focus of the Outside/In episode titled "Never Bring a Sledgehammer to a Scalpel Fight."  This approach to managing invasive species, used by scientists for over a century, has had some spectacular failures, but there have been many success stories as well.  We'll look at the history of the approach, the arguments for and against, and examine the philosophical implications.  Is biological control messing with Mother Nature or our only hope against invasive species changing the landscape?

While frigid temperatures don’t feel particularly great, they do play an important role in the state’s ecosystem.

One way that cold temperatures can be helpful is by beating back the wave of invasive insects that have laid siege to the state’s forests, but State Entomologist Piera Siegert tells NHPR’s Brady Carlson that the some of the recent headlines about the impact of this cold on invasive bugs over-state the case in the Granite state.
