Early Detection and Rapid Response

Early Detection and Rapid Response (EDRR) means locating invasive species just as they are beginning to invade a particular area and quickly treating the new infestation.  This concept is fundamental to effective invasive species management.  Early identification and treatment makes successful control more likely and can save critical funding and resources for the park.  EDRR relies upon a strong communication network and the education of visitors, neighbors, and employees about potential invaders.
