City Nature Challenge GLOBAL Results

[Carrie Seltzer]

Please see below for the final tally of the global results!

If you plan to communicate CNC results to any of your groups or organizations, please feel free to use or adapt any of the language below. 

If you want to explore the stats from all of the cities, there's a spreadsheet for you to sort to your heart's content.

Hope to see you soon for our virtual celebration!

Hello incredible CNC organizers!

We've been up all night gathering each city's numbers as it became 9am, Monday May 10 for each of you – and now with our two Hawaiian cities finally getting their Monday started, we have the full results to share!

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)

We are beyond excited that we've finally topped one million observations in four days - and so appreciative of all the time and hard work you've put into getting us there by making the CNC happen in your community. Whether your city made 100 observations or 10,000 observations (or 71,000 observations–looking at you, Cape Town!), we are so grateful to have you as a CNC organizer.

We've attached some resources to help you look through the results and communicate them to your city's participants. These are Excel sheets and Word docs (instead of a Google sheet or doc!) so that you can sort the results and look at them whatever way you wish:

CNC 2021 Results Workbook: there are multiple spreadsheets in this workbook:

1. Collective results: the combined numbers across cities and platforms, and includes a full list of all the countries with participating cities
2. City Numbers: the official numbers from each city (collected at 9am, Monday, May 10 for each city). There are three groups of numbers for each city: (1) the TOTAL observations, species, identifiers, and observers; (2) the VERIFIABLE (has evidence, not captive/cultivated) observations, species, identifiers, and observers; (3) the RESEARCH GRADE (verifiable and has community consensus on the ID) observations, species, identifiers, and observers
3. % Verifiable and Research Grade: shows for each city the percent of TOTAL observations and species were VERIFIABLE, and the percent of the VERIFIABLE observations and species that have become RESEARCH GRADE. (Note: if your platform wasn't an iNaturalist platform, then you'll just have the first set of numbers - the TOTAL ones.)
4. Average Observations per Person: for each city, the TOTAL observations divided by the TOTAL observers to show the average number of observations each observer made
5. MASTER: includes all the numbers listed above for each city and includes the links we used to get the "City Numbers" stats
6. Hemisphere/Climate: Includes all the numbers listed above for each city, and each city has been classified by its climate type and if it's in the northern hemisphere, southern hemisphere, or the tropics (between the Tropics of Cancer & Capricorn). Use this sheet if you're interested to see how your city compared to other cities that are in your climate zone (and thus may have been experiencing similar seasonality/weather during the CNC).

***NOTE: if you see any mistakes with the stats for your city, let us know THIS WEEK. We apologize for any mis-typed results–we did stay up all night to gather them, so in our sleepy state we may have entered a wrong number somewhere. We'll send out an updated results workbook on Friday if needed, so if you see any mistakes, let us know by Thursday evening.***

CNC 2021 Infographic: highlighting the collective results and interesting finds from around the world. We wish we could've included more interesting finds–there were so many! We had a great time looking through all of them & searching out some new ones as well so we could have a diversity of taxa and a diversity of places represented.

CNC 2021 Collective Results for iNaturalist journal post: a document that you can cut and paste into an iNaturalist journal post, celebrating the collaborative results of the City Nature Challenge. This includes all the html formatting needed for links to work and for the infographic to display, if you want to highlight the collaborative results in your CNC project. This is the journal post we'll add to the CNC umbrella project; you're welcome to add it to your city's project as well.

CNC 2021 San Francisco results iNaturalist project journal: THIS IS AN EXAMPLE JOURNAL POST. You'll need to change it if you want to include both the overall collaborative results as well as results from your city. This is the journal post that will go up in the San Francisco CNC project, talking about local results as well as collaborative results. This includes all the html formatting needed for links to work and for the infographic to display. You're welcome to use this as a template to talk about your city's results, but be sure to change all the SF details out for information from your city! 

We'll hold some debrief meetings probably in early June - until then, hopefully you can rest up and recover from the City Nature Challenge!

Thanks,

Alison, Lila, and Amy
