The “Tracking Invasive Species with Pennsylvania iMapInvasives” newsletter is a triannual newsletter featuring stories written by natural resource professionals and citizen scientists from Pennsylvania who are doing work related to surveying, reporting, and managing invasive plants, animals, and insects in the state. Each story includes a connection to the Pennsylvania iMapInvasives Program, which operates iMapInvasives, an online reporting and data management tool used to track occurrences of invasive species. The goal of the Pennsylvania iMapInvasives Program is to assist natural resource professionals and citizen scientists by advancing their knowledge of species distributions in the state Pennsylvania and to provide a tool which stores both location and management details.
