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?

The state of New Hampshire has different management zones for the Emerald Ash Borer. The management zones shown on this map can help landowners and municipalities determine where they are in relation to the affected areas and, in turn, when they should start managing their ash trees.
