Do you want to make and share observations? Or, do you need help identifying something you have found? EOL and iNaturalist have teamed up to provide these capabilities for EOL Collections. You can make a checklist for making and sharing observations by turning your Collection into a shared EOL-iNaturalist Project, such as this Invasive Species Project. These Projects are great for school activities, species inventories and personal checklists.
