and more in the old google group as well.
I’m not sure why people consider marking something cultivated makes it trash. They do get less IDs. But it’s not because they are trash. The people who do IDs can choose whether to filter those out, and most do. So the interest just isn’t there for people doing ID help. You could try to recruit more people who care about them, i guess.
for what it’s worth i think they should be able to get ‘research grade’ equivalent as others have said, and i think they do have value when they are plants growing outside and being used by pollinators, potentially seeding into other areas, etc. However i don’t think they should be displayed on the range maps unless with a different symbology.
