The fungus Discula destructiva besmirched this creamy dogwood bloom and can eventually slay the tree. The parasite, which is devastating dogwoods in the East and West, is just one of the non-native organisms gnawing, sucking, and sliming their way through U.S. forests. The new Gallery of Pests from The Nature Conservancy (TNC) briefly describes more than 30 insects, fungi, and other troublemakers. Many accounts include photos of the organisms and the damage they inflict, along with maps that illustrate their spread. The gallery is the latest addition to TNC's invasive species site, which includes a host of resources aimed at land managers. To learn more about pesky invasive plants, for instance, consult Australian expert Rod Randall's Big Weed List.
