In recent years there has been an increase in awareness that introduced invasive species are having a significant impact on our economies, our environment, and our health. Many of the currently known invasive plants causing problems today were originally imported as ornamentals. Recent increases in global trade, including trade in ornamental plants, have created new opportunities for the spread of both intentional and non-intentional exotic species.

It is estimated that only 1% of the species introduced every year will become invasive. Invasive species include plants, animals including insects and pathogens. They have negative impacts on forests, agriculture, wildlife, water bodies and human health. They also diminish our recreational areas. Even though only a small percentage become invasive, the damage they cause is significant. The need for a national early detection and rapid response (ED/RR) system has been recognized in order to deal with this increasing threat.

Cornell Cooperative Extension of Columbia and Greene Counties is working with the Catskill Regional Invasive Species Partnership to develop an early detection and rapid response (ED/RR) system in the Catskill region. Research has shown that the best strategy to deal with invasive species is to identify and eradicate them before they become established. We urge people in the region to join us for this important task. The more eyes we have looking for these invaders, the better able we will be to deal with them quickly and effectively.

Free Identification Services for Invasive Species

Information and free identification services for potential early detection species is available at the Cornell Cooperative Extension of Columbia and Greene Counties offices in Acra and Hudson. If you suspect you have found an invasive species on your property or anywhere in the region, please contact us at 518 622-9820 or email us at
