SA iNaturalists - March 2020 Update

This month 170 users added 4,557 observations with 122 species observed for the first time, bringing our totals to 82,795 observations of 5,450 species.

There were 51 first time observers in South Australia bringing the total to 1,693. This number was boosted by a time zone fix which had been excluding a number of new users from the total.

The number of species observed in SA continues to climb at a steady rate, but this is primarily due to the increasing number of observers uploading ever more observations. The average number of observations required for each new species added in SA continues to decline. In 2016 every 8th observations was a new species, in 2017 it was every 10th observation, in 2018 every 21st observation and in 2019 every 32nd observation. The trend continues in 2020 with every 36th observation adding a new species to the SA total.

Top 10 observers for the month: cobaltducks (766), davidsando (734), davemmdave (385), mtank (371), wattlebird (202), stephen169 (190), mendacott (177), rfoster (133), anthonypaul (76), ellurasanctuary (72).
