City Nature Challenge 2018: San Francisco Bay Area's Boletim

13 de junho de 2018

Species new to the Bay Area from the City Nature Challenge

During the 2018 City Nature Challenge we ended up making observations of species that had not previously been recorded in the San Francisco Bay Area (the 9 counties that touch the bay). Some of these have made it to Research Grade, some are waiting to be confirmed or to have mis-IDs changed. Help us refine this list to figure out exactly what species we added in the Bay Area during the City Nature Challenge!

Congratulations to us, Bay Area - for the first time ever, we won the City Nature Challenge! And we won in high fashion, taking first for number of observations, species, and participants!

Diving deeper into the results for the Bay Area, 94% of observations submitted were verifiable, meaning that they had both a photo or sound AND were not marked captive or cultivated. By the time the numbers were pulled at 9 a.m. this morning, 50% of those observations had made it to Research Grade - a big thank you to our identifiers!!! Compared to last year's City Nature Challenge, even though this year's was one day shorter, we made almost double the observations we did last year, found close to 1000 more species, and had 2.5 times more people participate this year!

Congratulations to our top observer AND species-finder, @sea-kangaroo! @dpom and @damontighe also made it onto the top 5 for both lists. Our other top observers were @lemurdillo, @merav, and @wbsimey, and on the rest of the list for finding the most species are @catchang, @mrchasse, and @leftcoastnaturalist. We also want to thank our top identifiers: @graysquirrel made almost 3000 IDs, with @farinosa close behind with nearly 2000 IDs! @catchang, @boschniakia, @kueda, and @dshell all made over 1000 IDs - amazing! Big thanks to all of them (we'll be in touch about prizes) and equally big thanks to EVERYONE who got out and made observations and helped with identifying observations for the SF Bay Area City Nature Challenge this year!

And importantly, a HUGE THANK YOU to all of the people and organizations who held events in the Bay Area for this year's City Nature Challenge - we were able to offer more than 20 public events, where people could learn how to use iNaturalist, meet other people, and document a ton of species together. Building our local naturalist community is extremely important to us and is one of the main goals of the City Nature Challenge, so thanks to everyone who helped out, and a big WELCOME to all of the people new to iNaturalist who jumped in this year for the City Nature Challenge!

Looking at the impact overall, this year's City Nature Challenge was AMAZING! Almost 70 cities around the world, all mobilizing their residents and visitors to go out and find and document their local nature. The energy and enthusiasm for the City Nature Challenge was once again amazing- watching hundreds of thousands of observations flow in from around the world was truly inspiring. Our collective impact was obvious and incredible - we also gave iNaturalist its biggest 4 days in a row EVER!

Here are the results of the City Nature Challenge (as of 9:00 a.m., May 4 in each city’s time zone):
All 68 cities together:
Observations: 441,888
People: 17,329

All 63 cities using iNaturalist:
Observations: 423,845
Species: 18,116
People: 16,544

Here's the top five in each category:
San Francisco Bay Area: 41,737
Dallas/Fort Worth Area: 34,218
San Diego County: 33,448
Klang Valley / Greater Kuala Lumpur: 25,287
Washington- D.C. Metro Area: 22,800

San Francisco Bay Area: 3,211
Houston Area: 3,088
San Diego County: 2,946
Hong Kong SAR: 2,932
Dallas/Fort Worth Area: 2,560

San Francisco Bay Area: 1,532
San Diego County: 1,211
Boston: 992
Washington- D.C. Metro Area: 872
Los Angeles County: 855

...and some more results...
All together we also made 4,075 Research Grade observations of 599 rare, endangered, and threatened species globally, and added over 100 new species that had not previously been recorded on iNaturalist EVER!
City with highest percentage of verifiable observations: Tulsa, Oklahoma with 98.9%
City with highest percentage of verifiable observations making it to Research Grade: Cádiz, Spain with 70.5%
City that added the most new species to their region on iNaturalist through the City Nature Challenge: Kuala Lumpur (Klang Valley), Malaysia with 1392 new species documented on iNaturalist
City that added the most new iNaturalist participants to their region through the City Nature Challenge: San Diego, California with 733 new observers added during the City Nature Challenge

Observing is done, on to uploading & IDing!

Hey SF Bay Area! AMAZING job over the last 4 days going out and making observations! It's truly incredible what we can accomplish when we all work together, and not only did 1472 of us here in the Bay Area make 38,000 observations of 3100 species (so far!), but all together 16,000 people participated in making 385,000 observations of 16,500 species (so far!) around the world for the City Nature Challenge. So incredible.

So what's next? Well, we know many people were incredibly busy making observations Friday-Monday, and need some time to get them uploaded. We also know it takes time to get eyes on all these observations to try to confirm or refine the IDs. So, from now until 9am, Friday May 4, you should:

  1. Upload all your observations! As long as they were made April 27-30, you can upload them now and they'll still count for the City Nature Challenge.
  2. Help ID observations! Just like anyone can make observations, anyone can help with identifying observations. Here are all the observations made in the SF Bay Area for the City Nature Challenge that are not yet research grade! If you have some expertise or some naturalist know-how, feel free to help confirm IDs, correct mis-IDs, or try to take general IDs (e.g., "plants") down to more refined IDs (e.g., "California Poppy").

Our numbers will be pulled as final results at 9am this Friday, and results for the City Nature Challenge will be announced early afternoon that day!

What haven't we found yet?

We're doing a great job, SF Bay Area! Squarely in the lead for observations, species, and people. I personally think finding lots of different species is pretty rewarding, and it's how we can measure the "most biodiverse" city in the City Nature Challenge.

It's easy to see the species we have found, but what are we missing that we could potentially go find? Are you up for a treasure hunt? :) If so, I recommend the "compare" tool! These links are comparing species found in the SF Bay Area ever in April & May, versus the species we have found so far in the 2018 City Nature Challenge. You can see which "low hanging fruit" species are still out there to find!

Butterflies & Moths
Dragonflies & Damselflies
Ants, Bees, Wasps, & Sawflies


Asterales: Sunflowers and allies
Apiales: Carrots and allies
Boraginales: Borages and allies
Brassicales: Mustards and allies
Caryophyllales: Pinks, Cacti, and allies
Ericales: Heathers and allies
Fabales: Legumes and allies
Fagales: Oaks/birches/etc
Lamiales: Mints and allies
Malvales: Checkerblooms/mallows/rock-roses/etc
Ranunculales: Buttercups, Poppies, and allies
Rosales: Roses and allies
Sapindales: Maples, Mangos, Mahogany, Citrus, and allies
Saxifragales: Saxifrages and allies
Solanales: Nightshades, Bindweeds, Gooseweeds, and allies

If there are other taxa you're interested in that are not in this list, all you have to do is change the "taxon id" in both strings of the comparison. You can find the taxon id by doing a search for the taxon you're interested in on the "Observations" page and the taxon id will show up in the url! **Please note: you can only compare 500 species at once, so be sure to pick a taxonomic level that represents 500 species or less in the SF Bay Area. "Plants" won't work, but "Asteraceae" will.

Great job on Day 1 - on to Day 2!

Nice work, San Francisco Bay Area! When I went to bed last night, we were in the lead of all the cities participating in the City Nature Challenge! Of course, when I went to bed, it was also coming into the mid-part of Day 2 for Hong Kong, and while we were sleeping, they crept up and took the lead! I know we will overtake them once again as we get the observation-making ball rolling today, but let's also watch out for San Diego, who is keeping firmly on our heels!

You can check out the leaderboard here:

Where did everyone go yesterday to make observations? Where are you going today?

Yesterday I spent my morning at Edgewood Park taking in all of the amazing wildflowers & insects, and then ventured out to the Pillar Point tidepools in the afternoon for a not-so-great low tide... but luckily there is so much life in the tidepools that I could still find a ton of species even with the tide flooding out much of the reef. Today I'm going to the bioblitz at Trione-Annadel State Park! There are a ton of events happening today if you're looking to find a group to make observations with:

Have fun out there today!
