Hemlock Woolly Adelgid Workshop and How to Protect Our Native Forest

  • Thursday, January 30, 2020, 9:00 AM - 12:30 PM


The Workshop is Free and Sponsored by the Capital Mohawk PRISM of Cornell Cooperative Extension of Saratoga County 

Conservation Advisory Councils (CACs) and Conservation Boards (CBs) please join the iMapInvasives Team and the Capital Mohawk PRISM (Partnership for Regional Invasive Species Management) in a comprehensive workshop to learn how you can help to protect our Hemlock trees from the invasive Hemlock Woolly Adelgid (HWA). Hemlocks are a foundational tree and play an important ecologic function in our environment from providing critical habitat for animals to protecting our tributaries and native fish. Hemlock trees are one of the dominate trees found in northeastern New York State and provide an aesthetic appeal unique to our region.

The work shop will instruct participants on:

  • Identification of hemlocks and describe their critical function as a foundational tree;
  • The impact, life cycle, and identification of the invasive Adelgid;
  • Best management practices for treating HWA as outlined by the Cornell Hemlock Initiative;
  • Survey techniques specific for HWA, such as how many branches to inspect and the use of a throw rope;
  • iMapInvasives Mobile App training to report survey effort, presence data and not-detected data;
  • Using the online iMapInvasives platform, including viewing and querying data, setting up email alerts and submitting treatment data;
  • 2020: Pesticide Applicator Report Tool

The final portion of the program will provide a field component with a visit to a local hemlock stand at Saratoga Springs Spa State Park. A mock tree stand evaluation focusing on identify target trees for treatment will be conducted. Participants will also have the opportunity to practice using the iMap Mobile app in the field.

Participants will be eligible for pesticide re-certification credits:

  • Demonstration 10 Credits 2.50 / Forest 2 Credits 2.50 / Nursery, Ornamental & Turf 25 Credits 2.50 /
  • Ornamental and Turf 3a Credits 2.50 / Regulatory 9 Credits 2.50

All attendees will be required to register for an iMapInvasives account on line and then download the iMap mobile app to their cellular devise a few days before the workshop.
