What is an invasive species?
Invasive species are non-native species that can cause harm to the environment, the economy or to human health. Not all non-native species are invasive. Most are not invasive and many are highly beneficial. However, even a single invasive species can cause great harm. Invasives come from all around the world. As international trade increases, so does the rate of invasive species introductions.

Why are invasive species a threat?
Invasive species threaten nearly every aspect of our world and are one of the greatest threats to New York’s biodiversity. They cause or contribute to:
-Habitat degradation and loss
-The loss of native fish, wildlife and tree species
-The loss of recreational opportunities and income
-Crop damage and diseases in humans and livestock

What can I do to help prevent the spread of invasive species?
You can help by learning which invasive species are in your local area, and what actions are being done to manage them. Make others aware of invasive species. Avoid unintentional movement of invasive species as hitchhikers on items such as hiking boots, boat trailers, hay, mulch, and firewood. Replace the invasive plants growing in your garden with non-invasive alternatives. Get involved in organized efforts in your area to find and remove invasive species from local parks, playgrounds and campgrounds. Learn how to care for exotic aquarium fish and other pets and plants, so that they don’t become a problem. Ask your political representative to support invasive species efforts. Support non-profit organizations that work to combat invasive species.
