Invasive Species Watch
Hemlock Wolly Adelgid - URGENT
Look for: White woolly masses at the base of needles on undersides of hemlock twigs.
The hemlock woolly adelgid, a small, aphidlike insect that threatens the health of eastern hemlocks, was detected for the first time in Tompkins, Seneca, Yates, and Schuyler Counties, New York, in 2008 and now appears to be spreading.
This insect pest attacks both eastern and Carolina hemlock, which are often damaged and killed within a few years of becoming infested. According to a USDA pest alert, this pest threatens the health and sustainability of eastern hemlock in our area.
Numerous agencies, including the National Parks Service, NY Department of Environmental Conservation, and Cornell are tracking the insect's spread into Central New York.

You Can Help
Everyone can help minimize the destructive impact of invasive species on our natural environment. Whenever CNYNCTA is asked for special assistance, we'll post information and links to help hikers participate in these efforts.
This massive plant is impressive looking, but it can cause trouble for those who are sensitive to its sap. Serious burns have been reported. Growing up to 15 feet, the leaves can span from 2-5 feet. The thick green stem may have purple areas. The stem, leaf and flower stalks are hairy. Its small white flowers grow in big clusters, resembling Queen Anne's Lace. In late summer, small green fruit that quickly turns brown replaces the flowers.
