City Nature Challenge 2026

I would suggest giving it another try. It looks like you have six figure IDs (which is great!), and making that many without using Identify is quite an accomplishment. I think almost all high volume IDers use Identify to some extent.

You can definitely

in Identify and handle most observations in the modal. If some observation requires specific functions that aren’t there (maybe <2% in my experience), there’s a link to open each observation in a new tab, so it’s no more work to do that than opening each observation via any other page.

See info here:

You can also filter for a single user’s observations in Identify and go through them quickly if there are a lot of captive/cultivated ones.

Me too proteas in Western Cape Normally I clear that every day, but they will accumulate for me, till the CNC IDs are cleared. You can do a page of IDs, then go thru again if you usually annotate - flowers, fruit, buds, none. A small learning curve, and with a text expander for frequently used texts.

That’s a great idea, and something that we will talk to iNaturalist about for next year. By the third day of the CNC, I do send out an email to our project organizers whose projects have 0 or very few observations encouraging them that there’s still time to start making observations.

probably not humans… or is that too cheeky :face_with_hand_over_mouth:

The area I’m most active in is indopacific fishes.

I select the area by drawing a rectangle on the map.

I’ve tried many times in the Identify mode and cannot find any way to select the area.

  • Draw the rectangle in the observations view
  • copy the coordinates in the url. It should look something like this
    nelat=10.10&nelng=10.10&swlat=10.10&swlng=10.10
  • go to the identify page
  • add the coordinates to the identify page url.

Thanks … I’ve now found that I can use the right arrow key to zip through observations and X them more efficiently.

I hoped this would work as it sounds good, but I’m unable to get it to accept the location and it reverts to worldwide each time.

I drew a small rectangular in the water above Madagascar, and set the observations to needs_id on the Explore page. Then I copied the coordinates to identify page. Both the explore page and identify page have 144 observations.

Explore page

Identify page
https://www.inaturalist.org/observations/identify?nelat=-7.627502526966873&nelng=50.23610609977258&swlat=-11.26818985029566&swlng=47.07204359977258

just to clarify, there is no need to do this. Once you draw the bounding box in Explore, click the Filters box and then click ‘Identify’ at bottom right, and the spatial filter will be carried across

When you look at observations via Identify on the web site, is there any clue to which ones are part of CNC?

Is there acually any issue with the CV suggestions? Since yesterday I get strange suggestions for nearly any plant in my region (Switzerland).

Some tropical plants, some tropical chamaeleons, etc… Nice creatures, but not helpfull for any ID.

Is CV model lost in the amount of observations somewhere? Can you fix it soon please?

There are projects for all the CNC cities/areas, so you could add one of those to the identification filters. (Or just use the umbrella project: City Nature Challenge 2026).

For now - I am only IDing via my dedicated URLs for CNC.

oy vey! I had Unknowns in the whole Middle East down to half a page and now it’s 21 pages. well, at least a love of nature bodes well for peace and hope in the Middle East… lol…

Thanks. I’m not looking to add observations to the CNC. Its just that last night I put casual on about 100 observations of birch trees planted along the roadsides of a housing estate in Ireland, sometimes multiple obs of the same tree. I wondered if the observer was hoping to boost his city’s nature challenge but I couldn’t see anything that indicated CNC.

I think - the project badge only shows on obs, if the observer has joined the project. But it still counts … unless marked Casual.

I’m glad I don’t have to participate in this year’s CNC. Last year Málaga was taking part, so I had too, but I found it really stressing to take photos of everything. I’m going out every day anyway for my streak, but I like to take various photos of one organisms, then process my photos, crop, sharpen and maybe adjust light. Once everything is uploaded I go through them, annotate, add observation fields or to projects. All of that I didn’t do last year. Not to speak of the organiser who didn’t do a single ID. Fortunately there were not many participants.

I’m also from southern Ontario and have always been frustrated by this as well. I was leading a birding hike on Saturday and it was 5*C and windy and raining for most of it haha…

Similarly eBird does its “Global Big Day” on World Migratory Bird Day which is the second Saturday of May. Peak migration in southern Ontario is generally around 3 weeks into May so this ends up being up to half a month too early in some years.

I admit I am a little jealous, hahaha!

Today promises to be another scorcher. (We are in a 23 day heat wave that began 23 April.)

I was out Friday early and then again briefly later that afternoon but since then have decided my time is better spent making identifications for heartier, younger Observers, there being plenty at Needs ID in the local reto I recognize to species. In this way, perhaps I can encourage some fresh, local eyes and make a little difference.

(I suspect there is not any one date that would suit everywhere.)
