This year we’ve started sharing the key information from our monthly NBN Atlas data updates. These contributions from our 200 data partners are what make the NBN Atlas such a powerful resource for conservation, research and decision making and we think they’re worth shouting about!
We started the year with 304 million species records on the NBN Atlas and we now have over 335 million!
