iNaturalist Data in iMapInvasives

You can now view invasive species observations from iNaturalist in iMapInvasives!

  • We are using the continental invasive species list; some species might be native in your area but invasive somewhere else.

  • This includes data from the past five years only, updated weekly.

  • This includes only records with "research grade” status; each record must have a photo & two users agreeing on the species identity (Learn more about research grade status in the iNaturalist database).*

How to view the iNaturalist data in iMapInvasives:

  • Look for “iNaturalist data” in Layers On/Off (righthand side of the screen).
    • By default, this layer is toggled off – to toggle it on, you must first zoom in on the map**, or filter on one or more species with the filter tool.

  • To learn more about an iNaturalist record, click on the record in the map to view a window with more info.

    • Click on “iNaturalist URL” at the bottom of the popup window to view the iNaturalist record page.

Several iMapInvasives programs have active iNaturalist projects which may collect additional invasive species records. Learn more at the NatureServe Network Invasives Umbrella Project.

*Disclaimer: The iNaturalist data viewable within iMapInvasives comes from an export of data submitted from iNaturalist to GBIF (the Global Biodiversity Information Facility)These iNaturalist records are view-only within iMapInvasives,  and are not brought directly into the iMapInvasives database. iNaturalist records do not undergo the same review & confirmation process as iMapInvasives records; NatureServe does not guarantee the accuracy of iNaturalist records. In some cases, key iNaturalist records (e.g. high priority species, or first-in-area records) are entered directly into iMapInvasives, so there will be some duplication between the iNaturalist layer and the iMapInvasives presence layer.

Note: Some iNaturalist records have generalized or imprecise locations, and this may be documented in the coordinate uncertainty field. You can view this information by clicking on an iNaturalist record in the iMap online interface. Please note that a value of -1 indicates that no value was recorded for coordinate uncertainty for that iNaturalist record.
