Hemlock Woolly Adelgid (HWA) is an invasive insect that is increasing in abundance throughout Western New York. As one of our only native coniferous tree species, hemlock is essential for providing habitat for insects and animals but also for preventing erosion along the streams where it commonly grows. Unfortunately, Eastern Hemlocks do not have any natural resistance to this rapidly spreading pest. Infestation by Hemlock Woolly Adelgid can result in tree decline and death within a few years. 

Trees displaying early signs of infestation can be saved through treatment. The Land Conservancy recently received a Great Lakes Restoration Initiative grant to form an alliance with local partner organizations to monitor for and treat newly detected HWA infestations at properties throughout Western New York, and we are thrilled to do our part in preventing the spread.
