Priority Setting

AATV Meeting_001There are hundreds of invasive species impacting New York’s natural areas, economy and communities. Each of these species exhibits its own unique set and severity of impacts which are often influenced by habitat, associated stressors, and climate. In the Adirondack Partnership for Regional Invasive Species Management (PRISM) alone nearly 100 different invasive plants and animals have been documented. Many of these species have been long established and are beyond the point of effective control. Others are just emerging as threats and localized infestations can still be eradicated. There is no amount of resources or funding that could eliminate all known invasive species infestations from the landscape and the nature of invasive species themselves often limits the ability to develop and implement effective control measures. Therefore, the Adirondack Park Invasive Plant Program (APIPP) and other invasive species managers must prioritize their efforts on prevention, early detection and rapid response to those species and/or infestations that pose the greatest threats and whose management will result in the highest conservation returns.

The 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 prevention, management, education and outreach efforts. Those 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.
