25,000,000 Observations!

Today we've reached 25 million verifiable observations! Here's a time lapse video that shows when and where these observations were created going all the way back to launch in 2008. You can follow along with the total observation count as it grows.




At the end of 2018, when we reached 15 million observations, we wrote a blog post where we visualized what these observations would look like if each dot represented 100,000 observations. We've updated those figures below. We now have 250 dots: each row represents 1 million observations and each little block represents 5 million. The unfilled dots represent the 100 new dots since the last analysis.




iNaturalist observations now represent over 230,000 distinct species! That's 40,000 more than last time which, for perspective, is approximately the combined number of all bird, mammal, reptile, and amphibian species. We now have nearly 10 million plant observations and 6 million insect observations. We've passed 1 million fungi observations since our last analysis.

iNaturalist continues to have a strong North American bias, but we now have 2.5 million observations from Europe, nearly 1.5 million observations from Asia, and over 1 million observations added to Oceania, Africa and South America since our last analysis.

We ended up adding just shy of 8 million observations in 2018. As of today we've added nearly 10 million observations in 2019 and are on track to add another 6 million or so by the end of the year.



The core stats we show on the explore page are the number of observations, the number of species that these observations represent, the number of observers, and the number of identifiers. The graphs below show how these 4 stats have increased over time.




It is noteworthy that the number of species has also continued to increase rapidly. The Global Biodiversity Information Facility (GBIF) recently wrote a blog post about citizen science contributions to the GBIF archive. Their analysis shows that while there are other citizen science efforts that are generating more observations for a group of taxa (e.g. eBird for birds) or for a particular place (e.g. Artportalen for Sweden), iNaturalist stands out as the only global citizen science contributor that is generating observations of hundreds of thousands of species.

We're accumulating new species more and more rapidly - currently around 5,000 new species a month. But this growing rate is driven by the growth of new observations. It's actually getting harder to observe new species. Currently, about 1 in 400 observations represents a new species, but this rate is dropping over time. It will be interesting to see how iNaturalist continues to accumulate new species as they get rarer and rarer!

These 25 million records have a broad reach. iNaturalist data via GBIF has been cited over 340 times, which is just a fraction of the over 2,000 times iNaturalist is mentioned or cited in publications.

Thanks to every single person who helped us reach this 25 million milestone! And thanks to everyone who has donated to help us continue to improve the platform.

Hey Scott, you've left out 10 million observations in the first para - I guess it's testimony to iNat's incredible growth. A big thank-you to the entire team running this wonderful platform!

Love the new species / observation metric. Would love to see that mapped -- where in the world is above and below that average 1 in 400. Thank you Scott et al!

Let's get those fishy numbers up! I've been trying really hard to get anyone I know into "life listing" to get involved but it's been a slow go.

Amazing and wonderful exponential growth! I hope the developers are as excited about that as us out here on the front end...

Random note: I see that the bright dot at 0,0 didn't start showing up until about January 2019.

wow, iNat will need a lot of storage in a few years time growing at this rate!
An amazing project indeed showing so much of this wonderful world we live on.
And isn't it coincidental? the final picture in the timelapse reminds me of satellite photos by night, observations seem to be linked to electricity consumption clearly showing that the poor and oppressed have other things on their mind....

I see "global warming": The entire globe is warming up to the idea of using iNaturalist for citizen science! The curves of accumulating observations are the same shape as something former VP Al Gore would put up in a chart! It's probably no coincidence that the more recent images in the video begin to mimic the brightness of the night sky around the world. Absolutely fascinating...and so encouraging from the standpoint of citizen science.
Huge THANKS to the wonderful staff!

I continue to be amazed, fascinated, and delighted by Inaturalist, which is not something I can say about anything else i see online. The New Species info is wonderful. Would it be possible to see each of those new species as they are identified? It would be great if, for instance, you could arrange the 230,000 species ID'd so far by date of first identification.

Thank you to the identifiers and experts that take out time to give so many of us citizen scientists support and education of species. A big shout out to the bee experts, the herp experts (coolest personalities on INat), and all of the experts that give me a hand while observing in environmental disaster areas (I actually got our entire crew to sign up on one deployment :)
How can anyone ever be bored again? Such great friendships and common cause gatherings.
Donate to the greatest citizen science project in the world. All of our donations keep it going! Donate to INat!

Awesome! Was introduced to this by a colleague in the NSW Office of Environment & Heritage when she asked me to come from retirement and help with a citizen science/school project in 2015. Never enjoyed any databasing so much! Keeps me young I suspect. Just love the power of the algorithms that help along the way. More please!

hmm - I count 25,225,701 - where are you guys getting that count?

Posted by loarie 30 days ago (Flag)

My mistake. Maybe I was counting all observations, not just the verifiable ones? I noticed one of the observations I was looking at was #31133537. Sorry about that.

Posted by jmaughn 30 days ago (Flag)
Thumb

I count 29,278,176 including non-verifiable which is certainly more in the 30M ballpark - we probably won't hit 30M verifiable till pretty close to the end of the year.

Posted by loarie 30 days ago (Flag)
Thumb

@jmaughn you're right that more than 31M observations have been created, but many were also deleted. For example, there have been some occasions when someone has done a large csv import and then deleted it all, which increases the unique observation identifiers without increasing the actual observation tally.

There are also, for example, 250K observations without evidence *or* identifications which is why we use the verifiable count in our celebratory announcements rather than the overall total.

@gyrrlfalcon , @dloarie , & @carrieseltzer Is is possible or on the horizon to have a dynamic webpage with some of the figures above (and more!) that are frequently updated?! I'm asking for a friend: my inner data-phile. (Also, to repeat my comment above—great work/this is wonderful!)

Posted by ecologistchris 30 days ago (Flag)

Thanks, Carrie. That makes sense. My enthusiasm got in the way of my own, there.

Posted by jmaughn 30 days ago (Flag)

@ecologistchris I think the closest we've got to that are the ongoing stats page (you can also make it go way back) and the year in review pages (e.g. 2018). The time lapse video was a joint effort by @tiwane and @loarie and loarie made the dot charts basically by hand, so neither of those are easily automated. If that's still not enough, you can experiment with making your own through judicious use of the API. :-)

Posted by carrieseltzer 30 days ago (Flag)

@carrieseltzer Thanks! I somehow have not seen the stats page, but I can't wait to play with it! The stats that you show are always *super* pleasing, including these and the year-in-review pages! If I had the time or were already savvy enough I would attempt my own . . . maybe someday ;) Thanks and congrats again!

Posted by ecologistchris 29 days ago (Flag)

@carrieseltzer , are the post without ID or evidence resulting from uploads that failed or created by mistakes? I followed the link you gave and found about 100 from me, so I deleted them, but I'm quite curious how I made them to start

Posted by amarzee 29 days ago (Flag)
Thumb

@amarzee many of the obs without evidence or IDs are probably accidental or tests. Or maybe intentional placeholders.

Some may also be upload errors. 197K are from the Android app (add &oauth_application_id=2) where some users have had difficult errors where data fields from a single observation are split across 2 observations. As always, if you experience anything weird in the Android app, please send us a log file ASAP so we can investigate. Even better if you can replicate it. But I suggest any further conversation on the topic of real or potential (software) bugs move to the iNat Forum to keep the primary focus on this post about the milestone :-)

Has anybody noticed the bell curve similarities between observations, species, observers and identifiers? I find that cool 😎 and consistent. Anyway, I feel good to have gotten into it when I did. It was nice to be part of the 25 million threshold. We got a long way to go because insects alone have a million species and plants 🌱 have 500,000. Let’s hope that remains as many species are threatened and we are supposedly in a time of “mass” extinction. Though I have not seen much written about it recently.
