and demonstrating physical, biological, and chemical control methods for aquatic 
nuisance species. 
• Research, Cornell University, Aquatic Research Facility. Researchers are 
contributing to a 50+ year, long-term dataset on Oneida Lake, New York that includes 
information on invasives and an aquatic foodweb ranging from nutrients to top predators. 
An experimental facility examines foodweb impacts of New York invasives in research 
settings ranging from small-scale aquaria to large-scale mesocosms. 
• Water Chestnut Control, State University of New York Oneonta Biological Field 
Station in cooperation with state agencies, nongovernmental organizations, and 
private stakeholders. Focus is on nutrient export associated with control activities. 
• Japanese Knotweed Initiative, Delaware River Invasive Plant Partnership (DRIPP). 
DRIPP develops educational brochures and works with local community volunteer sites 
to provide best scientific guidelines and demonstration control sites (showcasing repeated 
cutting to keep knotweed under control and prevent it from spreading). 
• Japanese Knotweed Study, New York City Department of Environmental 
Protection, in conjunction with Green County SWCD. 
• Delaware River Invasive Plant Partnership, States of Delaware, New Jersey, New 
York, and Pennsylvania. 
A.33.3. CLIMATE CHANGE CONCERNS 
• With climate change, purple loosestrife could move further north, where biocontrol 
insects may not survive. The range of plants and insects may shift and southern invasive 
species could move into New York. 
• Water hyacinth is sold all over the state. Currently, it does not survive the winter in New 
York. However, this could change with climate change. 
• Climate change could cause changes in the native vegetation and, depending on the rate 
at which that happens, could lead to more pest problems. 
A.33.4. CLIMATE CHANGE ACTIONS 
(None reported.) 
A.33.5. RESEARCH ACTIVITIES AND INFORMATION USED 
• Dynamics of decomposition for invasive weeds (Phragmites) and native cattails ( Typha ) 
are being compared in order to determine the benefit of restoration efforts.
