About the PRISM System
New York State is divided into 8 PRISMS, funded through New York State Dept. of Environmental Conservation's Environmental Protection Fund and are hosted by varying organizations.
The Capital/Mohawk PRISM is hosted by the Cornell Cooperative Extension of Saratoga County. It includes the counties of Albany, Columbia, Montgomery, Rensselaer, Schenectady and portions of Fulton, Greene, Herkimer, Saratoga, Warren, and Washington.

What are invasive species?
Invasive species are defined as non-native species that cause or are likely to cause economic or ecological harm, or harm to human health. An invasive species can be any type of organism including plants, animals, and diseases. They moved from their native region into our region, usually with help from humans. In these new habitats, invasive species are freed from the factors that kept their populations in check - like predators, weather, and diseases - and their populations grow, quickly out-competing native species.
Invasive species are usually from a similar climate somewhere across the globe. Native plants and animals are not used to dealing with these new invaders, and are unable to compete. Native animals don't usually browse on non-native plants, giving these invaders an additional competitive advantage. They cost the U.S. about $120 billion each year due to control costs, lost production, and environmental damage, and threaten 46 % of federally endangered and threatened species. The threat of invasive species ranks second behind habitat loss as the greatest threat to biodiversity globally.
