Early Detection / Rapid Response

An early detection is when a new invasive species is found in an area before it has had a chance to become well established. Finding invasive species early generally allows you to conduct a “rapid response,” or to control the small population, eliminating it quickly before it becomes too difficult or costly to control.

In order to be prepared to conduct a rapid response, DEP is implementing an Early Detection and Rapid Response Plan. This plan puts into place measures to help make DEP staff, the public, and visitors to the upstate watershed who are engaging in recreation activities aware of specific species to look for and to know what to do if they find them.
