City Nature Challenge: the results are in!

A huge THANK YOU to everyone who helped organize, participated in, and identified observations from the 6th annual City Nature Challenge! Despite the ongoing COVID-19 pandemic, we had over 10,000 more people participate compared to last year, and for the first time ever, we made over one million observations in the four days of the challenge!

Here are the collective results:
Observations: 1,270,767
Species: 45,300+, including more than 2,100 rare/endangered/threatened species
Observers: 52,777

Most-observed species globally: Mallard (Anas platyrhynchos)

Here in the Bay Area, our results were:
32,181 observations
2885 species
2265 observers

Although it wasn't a competition this year, we HAVE TO point out that (yet again) we had the most participants of any city! What an amazing community of nature-appreciating folks we have! An enormous THANK YOU to all of you! And a special shout-out to our top...

The City Nature Challenge also contributed to the most observations uploaded in a week on iNaturalist again - and also gave iNaturalist the first two weeks ever with over one million observations uploaded!

Thanks everyone! Continue to help IDing those CNC observations - it takes awhile to get through them! We're looking forward to CNC 2022!

This was a fun weekend for me - time with friends, time in nature, and then time IDing observations from others. I was proud to finish in the top ranks for observations, species, and IDs. So many spectacular people in our area. Thanks for all the organizing!
