Target & Watched Species

AATV Meeting_001The New York State Department of Environmental Conservation (NYSDEC) ranks invasive plant and animal species by threat level on an ongoing basis through the New York State Ranking System for Evaluating Non-Native Plant and Animal Species for Invasiveness. APIPP further assesses these species using the PRISM Threat Ranking Forms. Those terrestrial and aquatic invasive species that are present in the Adirondack PRISM and rank “High” or “Very High” under the PRISM ranking process are classified as targets. Target Species are prioritized for APIPP’s ongoing prevention, surveillance, education and outreach efforts. Species that are present in New York State and have not yet been detected within the Adirondack PRISM, but rank “High” or “Very High” under the PRISM ranking process are classified as Watched Species for APIPP’s ongoing early detection efforts. The PRISM threat ranking assessment outcomes for APIPP’s Target and Watched species can be found below.
