In PlantID.net, I offer a link to iNaturalist observations of taxa found at Edgewood Park. This works because I know the place_id for Edgewood is 6727.
For instance, the link to get to iNaturalist observations of American Vetch at Edgewood is https://www.inaturalist.org/observations?taxon_name=Vicia%20americana&place_id=6727
I’d like to extend this capability to other parks covered by my website, but to make a link URL I think I need to know the park’s iNat place_id, and I don’t find a list anywhere.
Where can I go to get a list of iNaturalist place_ids?
