MONITORING & MANAGEMENT
European Frog-bit Monitoring
Detecting an invasive species early provides the most realistic chance for management activities to successfully eradicate the population. However, aquatic invasive plants are often cryptic and difficult to locate before widespread population growth. Detecting a species requires thorough surveillance of all preferred habitat for a given species. Documentation of surveillance efforts provides critical information on where the target species is found and where it is not.
The European Frog-bit Collaborative developed a series of ArcGIS tools to assist managers in the Great Lakes region with monitoring and delimiting European frog-bit.
Prioritizing monitoring locations
The Survey Prioritization and Data Editor web app serves dual purposes: to assist managers in planning European frog-bit survey locations by visualizing the existing data along with relevant ancillary datasets, and to give data contributors a way to edit survey data that they have collected and shared. Ancillary datasets in the map include information on protected areas, boat ramp locations, dams, wetlands, and watershed boundaries as well as relative wind exposure for Great Lakes sites. EFB observations in the MISIN database are also included. Data contributors can edit features they have already created and create new features. Contributors are only able to edit features created using their own account.
