Map Invasive Species on Your Smartphone

image9

The Great Lakes Early Detection Network (GLEDN) is an online system that collects invasive species reports from casual observers, verifies these reports, and integrates them with other networks. DCIST verifies and collects data using the GLEDN smartphone app, which is available at https://apps.bugwood.org/apps/gledn/.  You can participate in three easy steps (click the green hyperlinks to learn more about using the app): 

Download the app and read the getting started guide or watch short tutorial videos to learn how to use the GLEDN app. More information on using the app is also available from this year’s webinar session.


Remember – DCIST is alerted of any invasive species information recorded for Door County and information collected helps us determine priority species, control projects, and outreach needs! 

Report an Invasive

Please fill out the form if you have observed an invasive species that you think may be a potential problem. Provide as much information as possible.  

Additional Tools & Websites for Invasive Species Reporting

*Note: you do not need to report species to multiple webpages.  Aside from the Wisconsin DNR, all of the databases below (and including the GLEDN smartphone app) communicate with one another through the Global Invasive Species Information Network.  


Global Invasive Species Information Network (GISIN) – www.gisin.org 

GISIN provides a platform for sharing invasive species information at a global level via the Internet. You can search, browse, and download data as well as provide data to GISIN over the web.   


Midwest Invasive Species Information Network (MISIN) - www.misin.msu.edu 

Report observations, explore data, or download factsheets on a number of Midwest invaders. 


Early Detection & Distribution Mapping System (EDDMaps) – www.eddmaps.org 

Browse species information and nation-wide distribution maps of invasive species. 


Wisconsin DNR - http://dnr.wi.gov/topic/Invasives/report.html  

Specific instructions for reporting aquatic, terrestrial, wetland, and NR-40 listed invasive species to the Department; also instructions on collecting and sending in voucher specimens.  The first step of action may be to email photo and description to invasive.species@wisconsin.gov if reporting to the WDNR.
