יומן של City Nature Challenge 2018: San Francisco Bay Area

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!

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!
