New Hampshire's forest rangers are cautioning visitors to this weekend's NASCAR race: If you're camping, buy the firewood locally or have a certificate showing it's been heat-treated.

They're trying to slow the spread of the emerald ash borer, an invasive species that has destroyed millions of ash trees over the past decade. It's been found in some areas of New Hampshire.

Rangers will inspect firewood coming into New Hampshire Motor Speedway from July 9-11. The campground at the speedway is the largest in the state and the race attracts more than 100,000 fans.

Whatever flavor you prefer, there is a New Hampshire brew that will do the job well. Today on Word of Mouth, we sample the state's craft-beer scene. Then, there are an estimated thirty thousand invasive species occupying America's eco-system. We have a conversation about the newest strategy against these pests: eating them. Next, we visit with Watson, IBM's cognitive computer and Jeopardy champion, to learn about its newest and slightly surprising endeavor in cooking. Plus: a tale of food and Spanish history from the American west.

We thought this was a pretty exciting idea. After all, we are full of invasives here in New England where the Europeans first landed. To get the ball rolling on  your "invasivore" diet, here are five recipes that can be made with invasive species found here in the Granite State.

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.

The cinematic signal of high plains desolation has an even more pernicious side: it’s an invasive species known as Russian Thistle, and it’s wreaking havoc across the United States. George Johnson is a writer based in Santa Fe, and a regular contributor to National Geographic, where he wrote about fighting the tumbleweed menace in his own backyard.

Eradicating Invasive Species: Part 1 - Plants

Purple Loosestrife, Autumn Olive, Norway Maple and Multi-flora Rose may sound like plants you'd want in your garden, but actually, they're four of the 423 invasive plants currently in New Hampshire.
