The hemlock woolly adelgid (Adelges tsugae) is an invasive, aphid-like insect native to Japan. First detected in the US in the 1950s in Virginia, it has since spread throughout the Appalachian Mountains and into parts of Canada. This pest infests hemlock species in the eastern US, including the Carolina hemlock (Tsuga caroliniana), which is endemic to the southern Appalachians. If left unmanaged, HWA infestations can eventually lead to host tree mortality, highlighting the importance of effective management strategies. This new publication explores the role of light gradients as a potential silvicultural management tool. Check it out!
