Hemlock Woolly Adelgid Surveying

27 March-- 2:00 pm - 4:00 pm

The hemlock woolly adelgid (HWA), Adelges tsugae is a destructive pest of hemlock Tsuga spp. It is native to India, Japan, Taiwan, and China. In 1919, HWA was first reported in North America in British Columbia. HWA was later detected in the eastern United States in Virginia in 1951. Finally, the first appearance of this pest in Atlantic Canada was confirmed in July 2017 in Digby County, Nova Scotia. As of now, HWA has been observed in four additional regions of Nova Scotia: Queens, Shelburne, Yarmouth, and Annapolis counties.

The Hemlock Woolly Adelgid is an aphid-like insect that targets hemlock trees, obtaining nutrients from storage cells at the base of the needles which ultimately kills the needles and eventually the tree. Although we cannot completely stop the spread of HWA in Nova Scotia, early detection can alert us to the presence of HWA. When HWA is confirmed in an area, the public can be encouraged to practice precaution when entering a hemlock stand to slow the spread of this pest.

A webinar on Wednesday, March 24th at 6:30 – 7 pm, will provide background information on the Hemlock Woolly Adelgid, which will prepare you for the field trip to survey hemlock stands for the presence of HWA. After registering, you will receive a link to join this zoom webinar.

On this field trip (March 27, 2 to 4 PM) you will learn how to survey for HWA, and be able to identify and report any sightings. 

 

The field trip location is still to be determined. We will be in touch with you after registering to finalize the location. However, for planning purposes it will be around the Wolfville/Kentville area. 

This event is free to the public. However, we do ask that if you have the capacity, please consider making a small ($5 or $10) donation to support the Blomidon Naturalists Society.
