One of the great features of the new NatureWatch NZ (which went live last Monday) is its "ID Please" feature. You can upload a photo, or photos, of a species you don't know, tag your observation as "ID Please", and other NatureWatch NZ users will suggest identifications. It's the internet at its finest.
Here's a look at the diversity of species that have been identified already. If there's something you don't know, pop over to NatureWatch NZ and log your observation. It's free. And while you're there, have a browse of the ID Please list to see if there's anything you know that you can help someone identify.
And, of course, if you disagree with any of the identifications made on any observations on NatureWatch NZ, you can sign in and suggest another ID. We're all about getting it right.
