Focused efforts to save hemlocks showing promise

Written by 

Good news on the hemlock front — the U.S. Forest Service reports it has had some success in ongoing efforts to protect these trees from the hemlock woolly adelgid.

The non-native invasive insect has killed thousands of hemlocks in the Southern Appalachians.

Treatments include soil injection of insecticides containing the active ingredients imidacloprid and dinotefuran, both of which have proved effective in reducing adelgid populations. Predatory beetles have been released in several areas across the two national forests in the region — Nantahala and Pisgah — with additional species of beetles studied as options by partner researchers and universities. An adelgid-killing fungus applied through aerial spray is also being considered.

The Hemlock Woolly Adelgid Working Group includes the National Forests in North Carolina, USFS Forest Health Protection, Southern Appalachian Forest Coalition, WildLaw, Western North Carolina Alliance, N.C. Wildlife Resources Commission, a local arborist, and the N.C. Department of Environment and Natural Resources.

This Must Be the Place

    art theplaceI did it again. It’s 9 a.m. last Saturday at the starting line of the Cashiers Trail Mix five-mile backwoods race. I knew I should have gotten more sleep the night before, should have at least had something to eat that morning. Shouldn’t have overindulged in the libations of Friday night, nor said the things I now regretted to my girlfriend.
