Protect the Hemlocks! Fence Raising at Thorn

  • The Thorn Preserve 55 John Joy Road Woodstock, NY, 12498 United States (map)

Four years ago, the Catskill Center planted four rows of young hemlocks, as a future biological control release location for hemlock woolly adelgid (HWA). These trees will grow into a thick hedgerow which promotes easy recollection of the beetle Laricobius nigrinus, a target-specific predator of HWA.

On July 14th, we will be repairing the fence that has protected the hemlocks from deer herbivory, to keep them healthy as they grow. Come help us protect these trees, and learn about the invasive species that are plaguing our hemlocks, as well as what you can do to help keep hemlocks alive in the Catskills landscape.
