When I was a kid in Michigan, my grandmother’s yard was filled with sassafras trees. So I was very interested in this article from the USDA about ambrosia beetles, which can kill a sassafras tree in just four weeks. Will milder winters cause the trees I remember from Michigan succumb to ambrosia beetles in the future? The article can be found in their CompassLive blog at https://www.srs.fs.usda.gov/compass/2018/01/18/how-cold-is-too-cold-for-redbay-ambrosia-beetles/.
