Tree of Heaven Treatments

To control the growth and spread of the invasive plant, Tree-of-Heaven (Ailanthus altissima), as well as mitigate potential impacts from serving as the preferred host plant to Spotted Lanternfly (Lycorma delicatula), the New York State Office of Parks, Recreation & Historic Preservation (OPRHP) seeks to hire a contractor to chemically treat populations of Tree-of-Heaven at Watkins Glen State Park using herbicide containing the active ingredient, triclopyr. Application methods will include hack-and-squirt, basal bark, and foliar spray, based on size. Methodologies are further explained in the Scope of Work.
