Range Covered by the 'Seen Nearby' Feature


While uploading an observation from Sri Lanka, I had to edit the location manually, since I was already out of the place from where I recorded it.
While trying to set the correct location, I noticed that the site gave me the name of the same species under the ‘Seen Nearby’ list for two different locations (ie. It showed the name of Starfruit as ‘Seen Nearby’ for both the Central Province of Sri Lanka and Medadumbara, which I think has a distance of about 31km between them).
What is the approximate range that is covered by the ‘Seen Nearby’ feature and how can I use it more accurately to get the correct species?
You can view the observation stated above here:


I have also often wondered within what range an species counts as "Seen Nearby.
I’m not sure what it is, but I’m curious to see what others have to say…

I frequently see this and have always wondered how far away that can be. I hope to hear some parameters or clarity in the matter.


I could be wrong, but I think it means within 100 km?

I hope that as iNat accumulates more and more records, the “Seen Nearby” circle can maybe be made smaller?

From the old group :

So it is 100 km, and within 45 calendar days (anyyear +/- 45 days) so if you see something in March and the only prior iNat record was from the exact same gps but in September, it will not be considered as seen nearby

Please note

  • there are clear bugs where it does not get it right, where something should qualify but is not reported as seen nearby, II have documented this several times and communicated it, I’ve never heard back on those bugs
  • you should not consider something not reported as seen nearby as not a viable choice, both due to the 45 days criteria, but it may just be there are no iNat records from it yet, especially outside busy usage areas
