Survey Methods and Observations
The Hemlock Woolly Adelgid (HWA) survey of the SLELO-PRISM region was conducted from January 2021 to April 2021. Several Highly Probable Areas (HPAs) within the 13 Priority Conservation Areas (PCAs) were surveyed by Brittney Rogers, Robert Smith, Megan Pistolese, and Frank Williams for signs and symptoms of Hemlock Woolly Adelgid (HWA).
The following tables of the PCAs include the location of each HPA, average HWA density, % of trees infested, crown density, and whether hemlock needleminer (Coleotechnites spp.) or tip blight (Sirrococcus tsugae) was found on these trees. The tables indicate that HWA was found at three of these sites (Independence Park, Camp Hollis, and Oswego County Reforestation Area). Landowners/managers have no obligation to treat this insect, but we encourage treatment for two reasons; 1) to protect the land managers investments by supporting tree stand health, integrity and resiliency to other forest pests and pathogens and 2) to reduce the rate of spread of HWA into other parts of our region. All data was recorded using iMap3 Forest Pest Data Collection Tool.
Of the 30 HPAs searched, Hemlock Woolly Adelgid was detected at 3 HPAs.
