Lower Hudson PRISM
The mission of the Lower Hudson Partnership for Regional Invasive Species Management is to protect the rich biodiversity and ecosystems of the Lower Hudson region through partnerships and collaborations that focus on controlling the introduction, spread, and harmful impact of invasive species.
To combat the impacts of invasive species, DEC created and supports the Bureau of Invasive Species and Ecosystem Health (BISEH) within the Division of Lands and Forests. This group works across the state by providing expertise, assistance and action where invasive species are a threat. BISEH collaborates with numerous stakeholders including State and Federal agencies, non-governmental organizations, industry and notably through Partnerships for Regional Invasive Species Management (PRISMs).

NYIS.INFO links scientists, local, state and federal resource managers, policy setters, educators, and grassroots efforts to help you become part of the battle against invasive species in New York.
Croton River Hydrilla Control Project
DEC and partners have developed a plan to control Hydrilla verticillata (hydrilla) in the Croton River. Hydrilla grows and spreads rapidly and is one of the most difficult aquatic invasive plants to control and eradicate in the United States. Infestations can have negative impacts on recreation and tourism, as well as severe consequences for aquatic ecosystems.
Methods of Control
Three broad categories cover most invasive plant control:
mechanical, chemical, and biological. Mechanical control
means physically removing plants from the environment
through cutting or pulling. Chemical control uses herbicides to kill plants and inhibit regrowth. Techniques and chemicals used will vary depending on the species. Biological controls use plant diseases or insect predators, typically from the targeted species’ home range. Several techniques may be effective in controlling a single species, but there is usually one preferred method—the one that is most resource efficient with minimal impact on non-target species and the environment.
US Forest Service
The Chief of the USDA Forest Service has identified invasive species as one of the four critical threats to our Nation’s Forests and Grasslands. The USDA Forest Service has designed an invasive species program whose goal is to reduce, minimize, or eliminate the potential impact of invasive species across all landscapes and ownerships.
