A tiny beetle from the Pacific Northwest may be reversing the fortunes of the region’s remaining hemlock stands.
Once thought to be doomed by a sap-stealing insect from Japan called a hemlock woolly adelgid, North Jersey’s hemlock groves now appear to be in the aftermath of a near fatal attack, said Rosa Yoo, an assistant regional forester with the state forestry service.
A series of cold winters several years ago has received some credit for the reprieve. There is also a predatory beetle brought in from the West Coast in 2005 that Mark Mayer, the New Jersey Bureau of Biological Pest Control chief, said has helped him overcome a bought of depression.
