“iNaturalist is a place where you can record what you see in nature, meet other nature lovers, and learn about the natural world.  From hikers to hunters, birders to beach-combers, the world is filled with naturalists, and many of us record what we find. What if all those observations could be shared online? You might discover someone who finds beautiful wildflowers at your favorite birding spot, or learn about the birds you see on the way to work. If enough people recorded their observations, it would be like a living record of life on Earth that scientists and land managers could use to monitor changes in biodiversity, and that anyone could use to learn more about nature. That’s the vision behind iNaturalist.org. So if you like recording your findings from the outdoors, or if you just like learning about life, join us…We wouldn’t be able to make iNaturalist without many, many wonderful open source projects, open datasets, and public APIs, including (in no particular order): Catalogue of Life, uBio, Ruby on Rails, jQuery, Google Maps, Mark James’ Silk Icons, and many more we’re probably forgetting. We’ve also been helped by many people along the way, including Coye Cheshire, Andrew McDiarmid, and, of course, all our awesome users!”
