As I am sure most people reading this are aware by now, this year’s CNC event has caused a lot of disruption and frustration for many iNat users and curators. In the interests of being proactive and solution-seeking, I thought I’d put together a post compiling the exact issues, and potential actions…

Or just get rid of CNC altogether and think of other ways to promote interest in biodiversity/iNaturalist? These kind of shenanigans undermine the notion that iNaturalist can be a place for serious citizen science and data collection. Also, CNC was started back in 2016 when iNaturalist was not wel…

[image] jsamyn: 5-10 organisms in one observation for that we have DQA - not a Single Subject. If you use that the obs goes to Casual.

If CNC is to continue I strongly support making Casual observations ineligible for inclusion in the counts. Also allowing much more time before a winner is announced since it takes months to really deal with all the submitted records.

I have been thinking about this for days. Background: I am just an Observer, not a very good Identifier, and here we have “Retos”, periodically, in which I participate lightly but not competitively, which is to say I do not change my habit at all. Tangential background: a friend of mine once desig…

Let the winner be the first to cross 60% RG That would be Graz this year. Say the first third of identified obs are the WOW and the straight forward (mostly done), and second third is the straight forward but we haven’t got to them yet. The last third is the blurry green stuff, who knows?! (And fr…

Let’s face it, what we saw in this year’s CNC was a contest to see who could cheat the most - La Paz or Cochabamba. Their regional rivalry should be settled on the football field, not on iNat. They should both be sanctioned until they clean up their act.

Cochabamba project has been flagged. Not La Paz. Yet. But only 6% RG Macao is 39% RG which matches the average.

Macau put on a showing as well - I’ve never seen so many flags generated by such a small project before!

I have been finding a good way to quickly whittle down the numbers of plant species in one project: by looking at the species page, and examining observations one species at a time. This way I usually end up discarding as cultivated quite a number of plant species very quickly, especially if I star…

Thank you, I didn’t know (obviously) and will definitely make use of that going forward!
