The New York Power Authority (NYPA) received new operating licenses for two of its hydroelectric power projects and is implementing a series of Habitat Improvement Projects (HIPs) to help comply with the terms of each facility’s operating license. Two HIPs, one in northern NY and another in western NY, focus on a multi-year effort to control approximately 25-acres of invasive wetland vegetation to protect and enhance several hundred acres of high-quality marshland.
Working closely with NYPA and stakeholders including Federal and State resources agencies at each power project, Kleinschmidt helped develop Invasive Species Control Plans for multiple areas encompassing nearly 25 acres within much larger several hundred acre marsh ecosystems. Development of these plans included initial planning and mapping of invasive species, investigation of acceptable control measures that could be used to control the invasive species, permitting, development of bid documents, selection of contractors, and management and field monitoring of the invasive species control contractors. The Invasive Species Control Plans utilized Integrated Vegetation Management (IVM) techniques to target individual control measures to each of the target species locations. The largest-scale implementation effort was focused on common reed. Purple loosestrife, buckthorn, and Japanese knotweed were also controlled. Kleinschmidt performed long-term monitoring to assess native species recolonization within treated areas and directed spot treatments as necessary to ensure that invasive plants do not re-erupt.
Results have shown excellent efficacy over the course of the multi-year projects, including the near or virtual elimination of common reed and other target species within the extensive treatment areas. Native wetland plant communities are observed to be recovering over time, and the agencies and other stakeholders have been pleased with the success of the control efforts.
