When non-standard places are created by a user, there’s a check-box option to allow checklists. It appears that the creator of this place did not allow them, so there is no default checklist. That option can be changed, but I think only by the original creator.
Yes, and the user that created the place has a total of six observations and was last active in June, 2019 so I don’t think that messaging them to tick a box will work. Perhaps a site curator or admin can do so?
