The U.S. Department of Agriculture confirmed recently that the emerald ash borer, a tiny, glitter-green insect from China expected to kill virtually all ash trees in the East, is devastating trees across North America as we speak. The emerald ash borer could cost the Grand River Conservation Authority between anywhere $4 to $8 million over the next decade and result in the destruction of tens of thousands of ash trees, according to the authority’s top forester.

The emerald ash borer (EAB) is an invasive species with few-to-none natural predators in the United States. This leaves the insect to freely reproduce en masse. Its larvae feed just below an ash tree’s bark, interfering with the plant’s water and nutrient uptake and causing it to die.
