What is an Invasive Species?
Invasive species are non-native species that can cause harm to the environment, the economy or to human health. Invasives come from all around the world. As international trade increases, so does the rate of invasive species introductions. Invasive species 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; and crop damage and diseases in humans and livestock (from the New York Dept. of Environmental Conservation).
