It got buried in this thread (post 389) but I want to plug a fantastic website created @wy_bio here called iNat Explorer which covers most of the requests here, and maybe even some you hadn’t asked for yet!
I created a quick example of how it will help me, searching California for 2 species of oak (dark and light blue) and their hybrid (green) so that I could identify areas where there are likely hybrids, but which haven’t yet been identified or are under-counted:
You can also get much more granular, and make selections from a seemingly endless set of filters, allowing me to determine which wild oaks I had not already reviewed in CA that had ID disagreements and were also tagged with the observation field “possible hybrid” and to then sort by number of “faves” so that I could review any compelling oak hybrid observations that get buried in the growing pile of indeterminate genus/section level.
The UI takes a little getting used to at first, but the learning curve is pretty quick, and once you get used to it, there’s so much functionality in terms of filters and combinations you can apply.
I can’t really overstate how useful I’ve found the site, so if you’re looking for a function, check it out (click on ‘Filters’ to get started), and don’t forget to leave feedback on the forum post where the developer has asked and responded to feedback over time.
