“Eastern hemlock is a shade-tolerant species,” says USDA Forest Service research entomologist Bud Mayfield. “But extra sunlight may help it survive HWA infestation.” Extra sunlight equals fewer HWA, at least on potted hemlock seedlings grown under shade cloth.
“About a third of all forest insect species are saproxylic,” says USDA Forest Service research entomologist Michael Ulyshen.
Ulyshen recently edited a definitive new book called Saproxylic Insects: Diversity, Ecology and Conservation and wrote four chapters.
Approximately one third of all forest insect species worldwide depend directly or indirectly on dying or dead wood (i.e., saproxylic) and these organisms are known to be sensitive to forest management decisions. The loss of saproxylic insect diversity in Europe due to reductions in the amount of dead wood and old trees across the landscape serves as a cautionary tale for researchers and land managers working in other parts of the world. This presentation will provide a broad overview of these insects, their conservation and the ecosystem services they provide, with a focus on the southeastern United States.
