National Geographic - The Great Nature Project

What type of organism you see? Perhaps all you know is it's a “flowering plant” or “fungus”-- that’s ok. Others can suggest identifications if your photos and description are clear enough. If you know exactly what it was-- great! Use the look up feature to find the species name or taxon.

Your photos will be added to the Great Nature Project photo stream and contribute to a global database of biodiversity. As a part of the project, you will be able to track your observations, get help identifying organisms, and connect with a community of nature lovers.

There is also an option to contribute only to the photo stream.
