The effort to help manage and control hemlock woolly adelgid (HWA) in Grimes Glen is underway thanks to efforts by Ontario County Soil and Water Conservation District with support from CLWA.
Hemlock woolly adelgid (HWA) is an aphid-like insect impacting our region’s hemlock trees. Hemlocks are some of the largest and most beautiful trees in the Finger Lakes forests. Because they are shade tolerant, they often thrive in gullies and help to stabilize slopes and riparian corridors, support native assemblies of plants and animals, and keep our streams cool. HWA is a major threat to the stability of our tributaries that drain into the lake, and their loss could have negative outcomes on our water quality.
Local funding and technical support were leveraged to obtain grant funding from the U.S. Forest Service’s Great Lakes Restoration Initiative (GLRI) to implement a coordinated strategic Hemlock Woolly Adelgid (HWA) management initiative across Ontario County for several public land areas. Grimes Glen was identified as a high-priority treatment area for HWA and was the first to be treated, with 69 trees protected in November. Treatments will continue in the Spring of 2023.
HWA treatments are being used to save ecologically important hemlock trees as biocontrols are being further developed.
Efforts are ramping up to continue surveys this winter. The information collected will aid in prioritizing watershed areas for HWA management efforts in the future. Stay tuned for upcoming workshops in the coming months.
Do you have HWA on your Property?
If you have Hemlock trees on your land, there is a good chance that HWA is present.
CLWA is actively gathering survey requests from private property owners. The more data we have on HWA and its whereabouts on hemlock stands in our watershed, the more we can do to prevent its spread.
We will come to your property and survey for HWA using New York State Hemlock Initiative reporting standards. We can offer you a full report on the health of your hemlock stand(s), and recommend certified treatment applicators.
Use the link below to submit an HWA Survey Request on our website. We will contact you shortly after your submission to set up a time for us to come survey your property this winter. (You do not need to be present for the survey).
