City Nature Challenge 2023 Results!

Thanks so much to everyone for another wonderful City Nature Challenge! It's always so incredible to see all the biodiversity in all these different places we call home, and we truly appreciate everyone who took the time to get outside and make an observation, helped with identifications, spread the word, held an event, and more! And of course a huge THANK YOU to all of our local organizers: they're the ones who make the City Nature Challenge happen in their cities, and this event would not be successful without them.

Since not every city uses iNaturalist for the CNC, we wanted to make sure to share the full collective results with all of you:

Total # of observations: 1,870,763
Total # of observers: 66,394
Total # of species documented: 57,227+, including more than 2,570 rare/endangered/threatened species
Most observed species: Mallard duck(Anas platyrhynchos)
Number of participating countries: 46
Number of participating cities: 482
See the infographic below for some interesting and fun finds from around the world!

And mark your calendars, next year's City Nature Challenge is April 26-29, 2024!

If your city doesn't currently participate in the City Nature Challenge and you wish it did, find someone willing to be your city's local organizer and have them fill out the "Interested in organizing for CNC 2024" form!

Might you consider some new targets for most of the cities among the 482?
Who will never feature among total obs and species.

The really interesting.
New species?
Redlisted?
Range extension?

Level the playing field so EVERY city has a target to aim for.

I am from Cape Town. But scrolling down to the bottom of the list, and hoping to encourage them to enter again next year.

Maybe we could encourage identifiers from the top of the list, to mentor a city which desperately needs help with IDs. (I will get to Western Cape - and I never did get to CNC22 for Rest of Africa)

I thank the organizers and congratulate them on this successful CNC.
In Brazil, we more than doubled the record number of observations from CNC 2021.
This year we had 20 projects participating
Although there are still relatively few records for the TOP regions/cities, the progress and progression year by year has been remarkable.

In Brazil we have had: 28.652 Observations done by 891 observers, with 4.687 species identified by 876 identifiers.

Emphasis on cities participating for the 1st time would be a great encouragement...
