Overview

EDDMapS is a web-based mapping system for documenting invasive species and pest distribution. It is fast, easy to use, and doesn't require Geographic Information Systems experience. Launched in 2005 by the Center for Invasive Species and Ecosystem Health at the University of Georgia, it was originally designed as a tool for state Exotic Pest Plant Councils to develop more complete distribution data of invasive species. Since then, the program has expanded to include the entire US and Canada as well as to document certain native pest species.

EDDMapS' goal is to maximize the effectiveness and accessibility of the immense numbers of invasive species and pest observations recorded each year. As of March 2024, EDDMapS has over 8.2 million records.

EDDMapS aggregates data from other databases and organizations as well as volunteer observations to create a national network of invasive species and pest distribution data that is shared with educators, land managers, conservation biologists, and beyond. This data will become the foundation for a better understanding of invasive species and pest distribution around the world.

Why do we care about invasive species?

The biological pollution caused by invasive species is extremely challenging, because even if we never import another non-native species, the ones already invading our native ecosystems will continue to grow and spread. Mapping invasive species is the first step towards their control or eradication.

Users simply enter their observations either in the online form or through one of the invasive species reporting smartphone applications.

How does EDDMapS work?

EDDMapS serves as a platform to document invasive species and pests. Through EDDMapS, participants can submit their observations or view results through interactive queries into the EDDMapS database. Participants can maintain their personal records and visualize data with interactive maps.

All data is reviewed by verifiers prior to appearing on maps and in data queries to ensure all data is accurate. The data is made freely available to everyone, including scientists, researchers, land managers, land owners, educators, conservationists, ecologists, farmers, foresters, state and national parks, etc.
