iNaturalist is a community website for sharing pictures and observations of plants and animals. To enable easy sharing of observations, iNaturalist offers a free Android app and a free iOS app. Using the apps you can take a picture, geo-locate it, write your observations, and upload to the iNaturalist community. If your observation is incomplete, for example if you’re not sure of a scientific name, you can ask the community to add comments to improve the recording of your observation.
Applications for Education
I learned about iNaturalist through an excellent post on the Google Lat Long Blog that outlined the efforts of a group to compile a large collection of observations about the Pepperwood Preserve in California. Pick a woodlot or nature preserve in your area and have your school build a record of observations about that area.
