SA iNaturalists - April 2021 Update



This month saw a significant boost in both observations and observers due the first day of the City Nature Challenge falling in April and a new Uni of Adelaide project.


This April saw 10,295 observations covering 1,843 species from a new record of 529 observers. There were 139 species receiving their first iNat record in SA. This month there was a record 199 new observers contributing their first observations in SA. Upon this months observations, 556 identifiers contributed a total of 17,122 identifications.


Uploads for SA at the end of April stand at 198,116 observations of 7,634 species from 3,192 observers with, as of today, 3,735 identifiers providing 367,591 identifications.


On the final observation day of the City Nature Challenge we surpassed 200,000 verifiable observations in SA. The City Nature Challenge brought in 5,361 observations of 1,101 species from 157 observers. An amazing achievement where across the 4 challenge days an observation was uploaded on average every 64 seconds!


The addition of a Uni of Adelaide zoology class project this month also boosted the number of observers in SA reaching a new record of 199 new observers.

200,000 Verifiable Observations!




On the last observation day of the City Nature Challenge we passed 200,000 verifiable observations uploaded in South Australia!


Congratulations to all who have contributed to this milestone. The first observations in SA were uploaded around mid-2011 and had only reached 4,500 by the end of 2017. Since then however the rate has increase dramatically reaching 23,500 by end of 2018, then 66,800 by end of 2019, and on to 162,400 by end of 2020.


We surpassed 100,000 observations in May 2020. It took 9 years to reach that milestone. The next 100,000 took just shy of 12 months. We are currently uploading approximately 290 new observations a day. That's a new observation in SA every 5 minutes!


If the trend continues, we'll be looking at reaching 300,000 observations around the end of October this year, in only 6 months. With the Great Southern Bioblitz in late October we may even reach it sooner.


Quick Stats:

  • 3,199 observers have uploaded records of 7,648 species across the state
  • Since the first 100k, we've had 1,263 new observers and 1,778 additional species identified.
  • 67.6% of all verifiable observations are Research Grade
  • 2,852 observations of 139 Threatened species
  • 14,378 observations of 543 Introduced species
  • 3,791 identifiers have made 366,000 identifications on observations from SA
  • Observations break down: 29.2% Vertebrates, 36.7% Plants, 18.1% Insects, 12.4% Other Animals, 3.1% Fungi, 0.5% Chromista
  • Species break down: 11.6% Vertebrates, 35.8% Plants, 29.7% Insects, 17.3% Other Animals, 4.9% Fungi, 0.7% Chromista
