Trees, Pests & People

Trees, Pests & People is the story of three kinds of trees -- Walnut, Avocado and Ash. These trees are united by the threat of invasive insects and diseases -- forest pests from other countries that are killing trees across the nation. For the Missouri black walnuts, the threat of thousand cankers disease looms from a distance. For Florida's avocados, each passing day increases the chance that another tree will be found with the deadly laurel wilt fungus. And for the Ash trees of Baltimore, the scourge of the emerald ash borer is already a major battle. But more than the trees, this is the story of how these threats affect everyday lives, and how we can all fight the problem of invasive pests.
