Hemlock Woolly Adelgid Bio Control Lab Established

The New York State Department of Environmental Conservation (DEC) and Cornell University have announced the creation of a new biocontrol laboratory on the Cornell campus focused on protecting the state’s population of hemlock trees.

The $1.2 million lab, partially funded by DEC with monies from the State’s Environmental Protection Fund and headed by Cornell entomologist Mark Whitmore, is expected to be dedicated to researching and rearing biological controls to stop the spread of the invasive pest Hemlock Woolly Adelgid (HWA), which is threatening trees in about half of New York’s 62 counties and more than 15 other states. » Continue Reading.

Forest Landowners Take Note Of Hemlock Woolly Adelgid

hemlock woolly adelgidEastern hemlocks (Tsuga canadensis) are one of the most beautiful conifers found in northern New York forests. It can take up to 300 years for them to reach mature heights of up to 70 feet and diameters of up to 3-feet. They commonly live for 500 years and can live for 800 years or longer. Many are among the oldest trees in the state.

In their northern range, they’re found at a variety of elevations (sea level to near 5000 ft.) and on a multiplicity of sites (hillsides, valleys, shorelines, glacial ridges). Hemlocks are commonly found growing in mixed stands, with yellow birch, sugar maple, northern red oak, white ash, American beech, and white pine and can be distinguished from pine and by their short, flat needles. » Continue Reading.
