Reported this in the Google Groups just before the switch.
In my account settings, both my “Search Place” and “Names Place” are set to Ontario. The following observations search, with “threatened” checked, and place set to Ontario, returns observations of, among other things, Purple Pitcher Plant, Sarracenia purpurea :
Under “status” for the species, no status is shown globally, for Canada, or for Ontario. It is indeed a pretty common and widespread species across the province.
One of the subspecies of this species IS set as threatened globally (https://www.inaturalist.org/taxa/182747-Sarracenia-purpurea-montana). But this shouldn’t be rolling up to the parent species, especially as that subspecies is not even found in Ontario.
If that’s not the explanation, then I can’t explain it at all. Everything else in that observations search seems to be valid.
