The following query returns all species of plants (with flower) observed in Vermont from January to May: https://www.inaturalist.org/observations?introduced=false&captive=false&hrank=species&month=1,2,3,4&order=asc&order_by=observed_on&place_id=47&term_id=12&term_value_id=13&verifiable=any&view=spe…

I’m pretty sure this is leftover from the bug where changing the establishment means didn’t automatically re-index observations. That’s been fixed, but the fix wasn’t retroactive. https://forum.inaturalist.org/t/how-to-use-inaturalists-search-urls-wiki-part-1-of-2/63/320 I re-indexed the observat…

Adding &native=true seems to do it. https://www.inaturalist.org/observations?introduced=false&captive=false&hrank=species&month=1,2,3,4&order=asc&order_by=observed_on&place_id=47&term_id=12&term_value_id=13&verifiable=any&view=species&native=true Read more about it here: https://forum.inaturalist…

&introduced=false finds taxa set to unknown, native, or endemic. &native=true finds taxa set to native or endemic Then why does adding both &native=true &introduced=false results in unknown, native, or endemic?

[image] naturalist: Then why does adding both &native=true &introduced=false results in unknown, native, or endemic? Yeah, I agree, it doesn’t make any sense, but it works for me! :-)

Just keep in mind that there are a lot of native species on a lot of place checklists where Establishment Means is currently at the default “unknown” setting, and hasn’t yet been updated to “native” or “endemic.” Using &native=true will exclude introduced taxa, but it will also exclude “unknown” ta…

After playing around with this some more, I’ve concluded that &native=true does not do what I want. The documentation suggests that &introduced=false finds taxa set to unknown, native, or endemic. I assume that’s equivalent to not introduced but it doesn’t seem to work that way. What am I doing wron…

The query string at the very top of this thread (with parameter introduced=false) lists the following 7 introduced species: https://www.inaturalist.org/taxa/167599-Pulmonaria-officinalis https://www.inaturalist.org/taxa/862704-Scilla-siberica https://www.inaturalist.org/taxa/68357-Scilla-forbesii …

I haven’t dug to the root of the problem, but I think the issue is that those taxa are marked introduced on the Vermont checklist, but not on the observations. For example, https://api.inaturalist.org/v1/observations/1441185 [image]

Thanks for the explanation. It helps to know that I’m using the parameters correctly. Why haven’t all observations been re-indexed? Are there just too many of them?
