Aquatic Invasive Species Distribution

Aquatic Base Map with Legend_2015 A variety of monitoring programs collect information directly or indirectly about the distribution of aquatic invasive species (AIS) in the Adirondack region including the NYSDEC, Darrin Fresh Water Institute, Adirondack Watershed Institute of Paul Smith’s College, Lake Champlain Basin Program Long Term Biological Monitoring Program, and lake associations and lake managers, among others. In 2002, the Adirondack Park Invasive Plant Program (APIPP) compiled existing information about the distribution of aquatic invasive plants in the Adirondack region and instituted a regional long-term volunteer surveillance and monitoring program. APIPP trains volunteers in plant identification and reporting techniques to monitor Adirondack waterways for the presence of aquatic invasive plants.

Until recently, no systematic surveys were underway in the region for aquatic invasive animals. Data on non-native fish primarily are collected by the NYSDEC, but data on other aquatic invasive animals, such as zebra mussel and Asian clam, are largely limited to reports from individual lakes. In 2008, the NYSDEC contracted with APIPP to serve as the Adirondack Partnership for Regional Invasive Species Management (PRISM), and APIPP broadened its scope beyond plants to address all invasive species and now also serves as a repository for aquatic invasive animal distribution data. In 2012, APIPP initiated an annual training program for aquatic invasive animal identification and survey techniques and is expanding its volunteer surveillance and monitoring program to include aquatic invasive animals.

Our knowledge of AIS distributions in the Adirondack region is limited by the number of waterways that have been surveyed and the frequency of monitoring. In some cases, only a portion of the water’s shoreline has been surveyed. In other cases, a single specimen may have been identified without documentation as to its location within the waterway. It follows that a “no invasives observed” survey result indicates only that an invasive species has not been detected and does not preclude the possibility of its existence.

Information is still needed for a number of Adirondack waterways!
