In 2008, a group of concerned citizens and public agencies led by Douglas Johnson, a summer resident of Seventh Lake, formed the Regional Inlet Invasive Plant Program (RIIPP) to address Japanese knotweed in the Town of Inlet. At its inception, the Town of Inlet took the lead and managed the logistics of the program. Over the next several years, the program expanded to include knotweed treatments in multiple communities throughout the Adirondacks. Beginning in 2015, the Hamilton County Soil and Water Conservation District (District) coordinated RIIPP with the assistance of many partners.
Beginning in 2020, The Nature Conservancy's Adirondack Park Invasive Plant Program (APIPP) assumed the coordinating role for RIIPP with a Knotweed Management Partnership. Under this partnership, APIPP contracts with certified pesticide applicators to treat priority knotweed infestations on private and public land. Treatment on private land is supported by donations to APIPP and other costs are supported, in part, by the Environmental Protection Fund administered by the NYS Department of Environmental Conservation. Volunteer coordinators work with landowners to secure the written agreements required to treat the properties.
Management assistance provided by APIPP is intended to reduce the severity of high-priority infestations in order to enable private landowners to more reasonably control infestations on their own. Three years of consecutive management will generally reduce the severity of infestations; further maintenance by the landowner may be needed for long-term control of the infestation. Volunteers are critical to advance this work. If you would like to get involved, please contact us for more info.
Volunteers provide the following support to the program:
