Invasive Pests

What is an Invasive Species?

Invasive species are non-native species that can cause harm to the environment, the economy, or 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).

Don't Move Firewood!

firewood


Firewood Transport Rules were revised August 2012 to improve regulatory compliance and enforcement. The existence of this regulation helps prevent firewood infested with invasive insects such as emerald ash borer and Asian long-horned beetle from being transported throughout the state, destroying trees from one place to another.
