SA iNaturalists - December 2021 Update

This December saw 7,079 observations covering 1,921 species from a total of 449 observers. There were 93 species receiving their first iNat record in SA. This month there were 84 new observers contributing their first observations in SA. Upon this months observations, 522 identifiers contributed a total of 12,381 identifications.
Uploads for SA at the end of December stand at 278,325 observations of 8,489 species from 3,988 observers with, as of today, 4,553 identifiers providing 508,608 identifications.
The international National Park City Foundation has awarded Adelaide National Park City status, making Adelaide the first in Australia and second in the world.

That's awesome Geoff :-) Thanks for compiling these lists, they are very interesting.
If it's not too big an ask, is it possible to do a summary for the year? I'm particularly interested in this number "There were 93 species receiving their first iNat record in SA." for the year.

Hi Brett, the +93 species in SA for the December month represents only the difference between the End of Nov total species for SA and the end of Dec total species for SA. I've not found an easy way to determine what exact species these are. They rarely represent 'first sighting records' in SA, more often the first time an observation has been IDed on iNat to a particular species (or first Genus or Family). The number also includes observations still at 'Needs ID' level. And includes new IDs on historic observations, i.e. might not represent a recent sighting.

Investigating these I've found that they generally consist of the following: (1) Legitimate first time iNat records IDed to Research Grade by knowledgeable people, (2) Observations at 'Needs ID', IDed by an expert observer, that is yet to be confirmed, (3) Observations at 'Needs ID' that are 'guesses' by inexperienced users or following the AI suggestions. (4) Cultivated species that haven't been labelled as such.

The 8,500 species recorded across SA represent the most well known and most sighted species. What remains, as I'm sure you're aware, are the harder to identify invertebrates, fungi, bryophyte and algae species that often require multiple photos showing diagnostic characteristics. If I had to hazard a guess, I'd say these represent less than a quarter of the 'new species' added each month. Most of those are still likely at 'Needs ID' awaiting a second expert to confirm. Only a handful of these are likely to be 'first sighting records' in SA (and many of those are yours).

I'll take a look at making a 2021 summary. It looks like 40% of all observations in SA were uploaded last year!

No prob's Geoff, I understand that it's a "rubbery" number (ie not 1st sighting, etc). But it's still interesting. To me it's an "indication" of the growth of knowledge of our wildlife. At the end of the day it's a photographic site and many id's, including mine, don't stand up to scientific rigour; but it's all we have :-) The more photo's of different species locally, the more the general knowledge grows, etc. It's a gr8 thing.
I guess it'd be interesting to see the total species for SA at the end of Dec 2020 vs Dec 2021. That would give the yearly "indication"? But it's not something iNat gives is it, it's based on you storing the end of month figures?

I looked at previous journal posts. As at Dec 2020, 7,129 species & Dec 2021, 8,489 species = 1,360 new species recognised over 2021 on iNat for the 1st time in SA. That's huge!
Solved it myself due to the work you do with the Journals :-)
