IDENTIFICATION TIME

Noon Wednesday.
I trust that everyone has now uploaded all their observations. There may be a few outstanding, but time to turn our attention to identification in earnest.

But before that ...
Well done Cape Town
What a magnificent job. During planning we decided that based on past projections we would need:
60,000 observations, 5000 species and 3000 observers to top the leaderboard. Everyone balked at these suggesting that they were far too ambitious.
That will teach them!

  • So we made 60,000 observations!! At noon today it was 61,729 - WELL DONE CAPE TOWN.
    I must confess that when I did my rounds of the Swartveld on Saturday I was extremely doubtful that people would contribute from such a bleak landscape: Only the Autumn Asters and Township Daises were in full flower, and the Swartland was black, and the Strandveld wilted and drab. And yet we done did it! A fantastic job, so give everyone a round of applause.

  • Species-wise we did not make 5000 species, but we are only just into the IDs and we currently have 3,453 species (on the CNC umbrella summary), but 3,880 on our project page. We will use the project page as our summary, and so we are 120 from 4000, so we are certain to make that - perhaps 5000 during one of the driest end-summers (April rainfall anyway) on record, was a little ambitious. But we can make up during the Great Southern Bioblitz when things are actually flowering (although it is late in October, so it will depend on the rains). .
  • Again, we failed to get our observer numbers. We will need to look into this. So an advance notice. 2022 will be about observers. So view the City Nature Challenge 2022 as a recruitment and awareness drive for your society. We managed just 1,268 observers: less than half our target. Still we made 5th place (at present), so not a bad result at all.

And dont forget that we were not alone. Just short of 50,000 observers worldwide contributed over one million observations (1,090,455) in 96 hours! A fantastic contribution to our urban biodiversity! Well done everyone, and hope that you had as much fun as we did.

OK: Identifications.

Currently we have:

If you are a specialist, then please help with finer level identifications.

Tips

  • Remember to fave any pictures-observations that you think qualify for consideration for observation of the CNC 2021 Cape Town. Everyone should fave at least 10 observations (and it is OK to include a few of your own)!
  • Remember to mark planted and captive observations.
  • Please tell users who posted too many species on an observation to split them. And those who overly split them: please ask them to join them up. And observations without pictures: please ask them to add some pictures. Use the Comments Box for these. Please help us curate the Challenge.
  • The curation tool is really a useful and powerful tool. If you need a refresher on how to use it, then please see here: https://vimeo.com/246153496
  • if there is a tree that needs identifying, add them to the tree project for the tree specialists: https://www.inaturalist.org/projects/trees-of-southern-africa

Good morning
Just wondering if we know the reason for the discrepancy between the numbers of species displayed on the Cape Town web pages and the parent City Challenge page? Currently 4225 vs 3726. Is it just a filter that needs changing or a more serious glitch that shall require us to amend or reload some of our data to reconcile the numbers? Interestingly looks like Hong Kong may have the same problem – 4142 vs 3462
And just to say a huge thank you to the Cape Town team for all the hard work you are doing. Also for arranging such perfect weather for us. What an amazing bunch of people you are!

INat counts species in many different ways. The biggest difference is strict species (i.e. only species rank) versus leaves (the terminal rank, so an ID of genus (say Peripatus, or even tribe or family) would count if there were no species in it, as would any subspecies). And there are a few other variations as well.
I suspect the the parent pages count leaves and the umbrella strict species.

But it may be that the umbrella excludes planted and captive from the species total - whatever, we have probably been told in previous years (see the fora).

((The weather for the challenge was easy: it was far harder getting the rain to keep you indoors for the identifications))

So No ID down from 19% to 14%, and RG up from 27% to 31%- Great Work!

Progress by group:
Birds: from 404 to 401 (needs feather and nest fundis)
Mammals: 260 to 278 (needs Scats, Signs and Skeleton crews)
Reptiles: 97 to 52 (skins and eggs, but some outstanding sitters)
Amphibians: 77 to 68 (the usual river vs clicking frogs, and quite a few calls)

Insects: 2,220 to 2,886
Molluscs: 992 to 1,091
Arachnids: 493 to 638 (no movement here: can some call the Spider Society to help?)

Fungi: 516 to 658

Mosses: 128 to 200
Ferns: 341 to 281
Monocots: 4,552 to 5,887
