Intro. to Invasives

Phragmites australis infestation

Not all species pose threats or cause harm to natural areas, forest or agricultural productivity, human health or the places and pursuits we care about. There are many native and non-native species present in the Adirondack region whose benefits significantly outweigh any impacts. The National Invasive Species Council defines an invasive species as a species that is non-native to the ecosystem under consideration whose introduction causes or is likely to cause economic or environmental harm or harm to human health. Known invasive plants and animals have been assessed by level of threat for New York. The Adirondack Park Invasive Plant Program (APIPP) tracks which invasive species are present or likely to arrive in the Adirondack region and then prioritizes which species to map, monitor, and manage based on a variety of factors including staff capacity, available resources, potential impact, and likelihood of successful eradication.

Species of Concern are those that are present or are approaching the region that are ranked highly or very highly invasive based on New York State’s Invasive Species Threat Ranking Assessments. APIPP and partners actively survey for, detect, and, if feasible, manage infestations, and provide guidance to others on management techniques.

You can help protect the Adirondack’s valuable natural, economic and cultural resources: learn how to identify harmful invasive species in your community, spread the word about their negative impacts, and join the regional effort to put a stop to their spread.

Remember – Some native species may resemble invasive species. Always confirm identification and learn about best management practices and permitting requirements before beginning any control program.
